James, I don't recommend using a multi-meter to set an amplifier's gain because it'll only read voltage accurately around 60 Hz (maybe 40-100 Hz) and can't tell you if the signal's clipped or not. I take the 100 to be the nominal rating in that? Shop for rockford fosgate at Best Buy. Pick the tone with the lowest clean volume setting and play it again at that setting. then enter to win a $350 gift card. The Rockford Fosgate® PerfectTune™ app is designed for use with the Rockford Fosgate DSR1 8 Channel Interactive Signal Processor with Integrated iDatalink Maestro Module. I'm assuming I would need to set the gain on the LC7i at a very low level as well as my amp gains to a low level to figure out the factory head unit's maximums, then go to the LC7i, set it's maximum and finally go to the amp and set it's gains. I followed your guide blew a $150 speaker. What gives?? Crutchfield: Audio, video, and more. This amp has a gain control, a bass boost control, and an external remote level control. You should leave the receiver set at its maximum clean output in order to achieve optimum amp gain setting. But i wonder what level the tones should be, -0db, -5db and so on. My experience was excellent, website is unmatched & customer support is top notch. It includes a pair of studio-quality headphones, a combination DAC (digital-to-analog converter) and headphone amp, USB mobile adapters, and a guide to getting the most out of your session. Also when I set 1kHz to max unclipped amplification then check 4kHz and 8Khz the higher frequencies show "sine like" waveforms but the shape is somewhat distorted ... and even when maxed out on the gain the 4-8kHz don't show up as a flat topped wave but rapidly spike the voltage and appear completely garbled.. • Mounting Hardware • Operation CD- (Test Tones & 7. I went into The Crutchfield Labs and set up an amplifier, wired to a power supply, a car receiver, and a pair of speakers. That said I then went on to check the output voltages after all had been set with lovely sine waves on the scope. This is because most meters are made to measure AC voltage accurately at 50-60 Hz (the common frequency of all power systems around the world). C. L. E. A. N. gain setup system test tones available as MP3 download from Amazon On Demand, Rhapsody, Google Play, and Spotify, labeled "3sixty. If you go that route, immediately save to your laptop incase things get messed down the road. When it distorts, you can clearly hear it buzz. I don't know of any 5-1/4" speaker that can play bass tones very well, in spite of their specifications. Christhian, Disengage the amp's filters for these steps. Check out this overview of a typical installation to see the steps involved when you install an amplifier in your vehicle. Kenyon, Test tones and oscilloscopes are commonly used to set gains in audio equipment - a device's input sensitivity to the output of a preceding device in a system. I followed your o-scope method to the tee. For instance, the Amprobe 15XP-B multimeter I used in this Labs demonstration reads the voltage of a 0 dB 1 KHz signal about one-fifth the level that it reads at 40 Hz or 100 Hz. Working in a music store in Austin, Texas, I spent a few years manufacturing, installing, repairing, and operating sound systems. I may have read somewhere that it is safer to disconnect the speaker wires from the amp. But the answer to your question is that to put out 100 watts RMS through a 3-ohm load takes 17.3 AC volts RMS. I don't have a dummy 2 ohm load rated for that kind of power. These tones are best used in conjunction with external devices, such as a sound level meter or an audio spectrum analyzer. Most meters only read accurate AC RMS voltage around 60 Hz. John, No. Turning the gain back down until the distortion disappeared, I set the gain exactly where the amp and receiver were both at their maximum clean output levels: perfectly gain-matched. If it's just another gain control then my inclination is to set it to the max and leave it there, setting the on amp dial to minimum and turning the on amp dial up until I find clipping, backing it off to the clean signal point and leave it there permanently. For Tech Support, call In 2006, I finally came to my senses and got this job at Crutchfield. It means POWER! Thanks for taking the time to answer everyones questions. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. Gain Overlap If we want a “clean sounding” car audio system, it doesn’t mean setting the … i found my limiting Hz and volume level. Download this uncompressed low-distortion WAV file for measuring your system distortion level at 1KHz, beginning from the digital source: 1KHz / 0db tone @ 192KHz / 24bit samples - 60 seconds duration (zipped) Below is a sample measurement on Macbook 12" with internal loopback in place with the above WAV file as a sour Ashay, Yes, that's the way to proceed. Please enter your email address below. Great info here. Along the way, power flows through the circuit's transisters, inductors, and capacitors that have the ability to boost the subsequent AC (alternating current) output. Raise the amp’s gain until you hear it buzz, back off until it hums, and you’re done. Brian, Finding the maximum clean volume of your receiver is unaffected by the amplifier's gain setting. Cheers. The male singer's voice suddenly developed a rasp. Is simply rotating the gain knob to the voltage location that matches the head unit output voltage an accurate way to set it? PBR400X4D amplifier pdf manual download. Al the sine wave tones you need are in spotify. It didn’t "clip" at the top and bottom, it distorted in the middle. Thanks for the great info this will be very helpful for setting up my amps! These test tones are sine waves meant to provide a consistent signal for the KX amplifier to reference. And you didn't say what the impedance of your subs are. Car amplifier audio terms - like watts, volts, and efficiency - are explained. Glennon, Not knowing exactly what amplifier you have makes it impossible to give advice on how to wire subs to it. Using a standard hand-held multimeter to measure the voltage of a higher-frequency signal results in readings that are much lower and leads to inaccurate power calculations. I don't know which receiver you have, but you should set its subwoofer output as you would the gain - turn it up until it distorts, then lower it until it's clean. If you like the tone when using a bass boost, you must readjust the amp's gain control to compensate for the boost in over-all volume and ensure that no dangerous distortion ever plays. I can wait to try all this stuff out next week. In the Crutchfield Labs, I ran a set of tests and determined that "doing it by ear and music" works, but not quite as accurately or scientifically as using test tones. So I need to calculate how many volts 300 watts RMS is, then set the gain to that level. Rockford Fosgate P3D2-12 Punch P3 DVC 2 Ohm 12-Inch 600 Watts RMS 1200 Watts Peak Subwoofer. Your email address will not be published. I turned up the gain on the amp and it never went past 10V. Continue reading the article if you want to see how I came to this conclusion by my researching the issue in the Crutchfield Labs. Definitely recommend them. You can measure the signal's peak-to-peak voltage with your scope, as well as see when it clips. Kevin, You should set your receiver's EQ and the amp's bass boost to the way you normally listen to your music, before finding maximum clean volume and setting amp gain. Do we need to change the gain level setting each time we change the speaker or we can just used the current that we already set? When I isolate the head unit I'm checking the max output through the rca cables with a 0dB test tone suite I made.. once I found the max receiver volume at 0dB I disconnected all speakers and plugged the rca pre-amps back in. I imagine you have to bring the receiver volume back down somewhere to have headroom to bring the gain up. I've done some searching on the web but everyone says different. Read More. But both times, the amp gain setting was exactly the same as the other methods. Thank you! I made some test tones using NCH for people who wanna clamp there amp or set there gains. A lot of people set their amp gains to just above clipping, to achieve higher levels of sound. John, Each gain knob controls two channels - left and right - so setting gain with a pair of speakers playing is probably the beat way to go. Jordan, also in the Labs area at the time, complained that the 4K Hz tone was still ringing in his. This really helped me in so many ways !!! Anthony, You can certainly play test tones on your home theater, but I have never heard of a home theater receiver with a gain control, so you can't use the test tones for gain-setting. Our customers were recording studios, nightclubs, and touring bands. Thanks again. Mr, It sounds like your speakers can't handle the test tones you're using sending them very well. Some confusion. Or is it in some way different from the gain control dial on the amp? Why would I be getting a distortion buzz at such low HU volume? Clipping doesn't seem to be a problem for me. I'm just concerned that different subs/speaker runs may introduce resistance variation, and I'm trying to be accurate. Your description of ringing ears from setting your gain by this method does not sound fun... Brian, The spikes you see are probably more an artifice of your oscilloscope's response-time than the clipped signal's harmonic radiation. Also, would hearing protection inhibit your ability to accurate determine the clipping point? I took courses in radio and electronics as a teenager, and became a ham radio operator. If you were to have the gain somewhere else but still on the lower end, (say 10% or 20%), would the distortion point on the HU vary in any way? Do you leave it at the same max level as you just found? To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. We engineer the best audio systems for your lifestyle! They were so helpful & the company really seems to care. Any insight would be greatly appreciated. (PS: producing 300 watts through a 2-ohm load takes 24.5 volts.). Thank you. Is that correct? Repeat Step 2, noting the top clean volume settings, using the 100, 400, 800, and 1K Hz tones. So are we talking db or dbfs tones? It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision. Rating ... C.L.E.A.N. You'll probably get better results. Since 1974. rockford fosgate p400x1 Php 15,200.00 Punch 400 Watt Mono Amplifier The Punch P400X1 is a mono amplifier capable of producing 400 Watts into a 2-Ohm load and is designed for medium to high-powered subwoofer applications. Could this just be an artifact of class d amplifiers? Can't find the test tone disc. So using a oscilloscope what type of cd should I I use to set EQs line drivers processors etc, also what would I look for while setting them? Two subwoofers that can get wired together to form a 4-ohm load cannot be rewired to form a 2-ohm load - that's impossible. Sound Ordnance M-4050 4-channel amplifier. If you do set gain via test tones and an oscilloscope with the speakers connected, you will be able to hear as well as see when the amp clips. Dann, The owner's manual for that amplifier is a bit confusing as to the actual function of the remote - whether it adjusts the amp's input gain or output level. I certainly cranked some swing those evenings in the Crutchfield Lab. When a speaker gets replaced, then the gain should be re-set to ensure that the new speaker doesn't distort. Find the receiver's highest clean volume, then the LOC's, and then the amp's. I figure a reading with the scope under the actual load is the best way to optimize the power output of the amp. I used test tones to set my amp gain for my component speakers. After further testing, I've discovered it's only the right midrange woofer making the noise, but the strange part is that I'm not sure it's distortion. Can you use these same test tones for a home theater setup? gain setup system includes test tone CD; test tones also available as MP3 download from Amazon On Demand, Rhapsody, Google Play, and Spotify, labeled "3sixty.3 setup disc" (Punch amps and the 3sixty.3 use the same test tone tracks for set-up) Class … Personally, I think using test tones and listening for the buzz is an easier and more accurate method for setting an amp's gain. An example of a a clean waveform (left) and a distorted, clipped wave (right). Maybe that one speaker wire is picking up noise somewhere in the car? I turned up the gain to the amp’s top clean-playing point and read the volt meter. For setting a subwoofer amplifier's gain, you can use a 40 or a 60 Hz tone. Clipped signals, as you noticed, don't always take the form of a square wave. Monty, Googling "download 0dB test tones" brings up quite a few reputable sites where you can download tones and purchase test tone CDs. If you read that your amplifier's putting out 44 volts AC RMS, it means that it's outputting 968 watts into that 2-ohm subwoofer. Sincerely appreciated. This would result in a calculated wattage about one-twentieth of the correct output power. Should I check the whole process on head unit first then the loc and then the amp? even without the oscilloscope, the tones made it possible for me accurately set the gain. It's no secret - a low-pass crossover removes high-frequency content from a subwoofer, and a high-pass crossover removes low-frequency content from midrange speakers and tweeters. But seeing as most people don’t have oscilloscopes, I thought that maybe by listening to the tones through speakers, one could also set an amplifier’s gain correctly. Please help? Finally, I tried music and my ears alone. Current setup: infinity 475a amp - 4x75rms to 2x alpine coaxial 75rms rear, 2x alpine component speakers 75rms front and infinity 1600a amp - 400rms to single pioneer sub 400rms. Oh and I have the two 12inch MTX Terminator subs in a box whats a good amp? Our boxes are packed with biodegradable packing peanuts. (Punch amps and the 3sixty.3 use the same test tone tracks for setup.) Also, I have a yellow top batt ran to my primary and my amp ran to the yellow top so it has a standalone battery all for itself. Find low everyday prices and buy online for delivery or in-store pick-up 4 channel pioneer GM D8604 Check Crutchfield out first! Using test tones and your ears means it doesn't matter what an amp or receiver's visual display or markings show while setting gains. Or as a pair, front then rear or all together? Does your amp has boost power supply to get 17.2 V RMS? I took note of what the receiver’s volume reading was: 52. 3 use the same test tone tracks for setup. Tendai, The gremlin's in your multi-meter - it's only accurate at 60 Hz. Each tone creates a reference-level (0 dB) sine wave that you can observe on an oscilloscope screen. However, it's safer using 0dB tones to set gain. If you purchased your equipment elsewhere, you can still get expert Crutchfield Tech Support - 90 days-worth for only $30. I have two other gain adjusters for the other 4 channels and the highest reading i get on either of them is 42. $219.99 $ 219. Zack, A subwoofer voice coil presents an inductive load, not a resistive load, to an amplifier's output - so measuring a coil's DC resistance with a multimeter won't accurately tell you its impedance. Do I put filters on the amps before tuning with the 100hz or after? Running two 500 RMS subs at 4 Ohms with an amp that puts out a max of 1100 at 4 Ohms, or the same two subs at 2 Ohms where the same amp puts out 2000 at 2 Ohms? But I've seen no advice regarding the remote control. Ken, You might have your voltage and wattage a bit confused. It's a full sentence. I started with the amp’s gain set to its minimum, and the speakers disconnected. i am also running a kicker key 180.4 amp to power these. I am not going to use the 45 Hz bass boost and will just leave that dialed all the way down to minimum. These formulae are based on Ohm’s and Joule’s Laws and you can’t break them if you tried. What am i doing wrong? Thanks. How do you prevent the other speakers in the car from not playing the test tone? Buck Pomerantz. If i turn my gain all the way up and the voltage is only half of my target number, what can be the problem? Mr, I didn't mean to imply that there was anything wrong with your speakers, just that you should use a higher frequency test tone (like 500 or 1000 Hz) to set the amp gain. Set your receiver’s EQ presets and the amp’s bass boost to the way you normally listen to your music. In, Nothing beats listening to speakers in your space. What is interesting to me is the 4channel amp when playing a test tone at max unclipped rca output does not form a square wave but starts to spike in the center with what looks like harmonic destabilizing centered around the wave peak which if gain is further increases shows the expected flat top however it still contains a sharp spike at the start and end of the square peak. I always got them back together again and working. Thanks for that. How do I incorporate remote level control on the amp (SoundStream PN1.650D) in this process? Its a 50Wx4 RMS. Speakers - Morel Tempo Ultra 5 1/4" Components For some reason the front channels (or amp #1 on the key) clip 1kHz with the gian all the way down. hello, We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. Is the amp working harder in the first scenario vs the second? I've made many purchases & never been disappointed. Use our handy wire gauge chart to find out. On the first day, setting it by ear and music alone, I ended up thinking I should never turn the receiver higher than 50, and the gain was set so that at that 50 volume, the amp put out 15.7 VAC at 100 Hz, or 62 watts. Are sine wave test tones in the 60-100hz range not appropriate for testing full range speakers using the "test tones by ear" method? question what test tone do u recommend for sub woofer, coaxial and component speakers. i was able to get some more range with the gains but when you switch from the Bluetooth single to a radio the volume of the radio blows you away. Plus, I don't usually listen to music full-blast for very long periods of time, so in real use, I would likely never be able to hear the difference. I get up to 7 but ohms law calls for 14.14. Read More. My 2 ohm sub calls for 48 watts. By using test tones played through a speaker, I wondered how accurately I could set an amp’s gain as compared to setting it by the other methods. I've since switched the speakers to 4 ohm to introduce a 2 ohm load and then I wired in a 12 inch earthquake dbxi in parallel to bring it back to a 1 ohm load. Instructions for setting amp gain using test tones; Download 0 dB sine wave test tones of 40, 100, 400, 800, and 1000 Hz to your preferred medium (disc, chip, file, phone). Class-BR Amplifier Installation Advisory. Given my background, they put me to work writing about some of the most complex electronic products Crutchfield sells: car amplifiers, digital signal processors, wiring, professional sound mixers, and PA systems. When in doubt, start at 100 Hz and then tweak to taste. When you're determining your HU's max clean volume, your gains at that point are at the minimum, right? Frequency response: 20-20K Hz. It does not take into account whether the source signal is clipped or not. In an amplified car system, you need to set your amplifier’s gain correctly in order to enjoy your music’s full range of dynamics and frequency response — hearing all the notes clearly, whether loud or soft. Thanks for sharing your knowledge! I recommend you to my friends. Adding 50% more power doesn’t result in 50% more bass. The volt meter read AC (alternating current) voltage, and the amp I used (a Sound Ordnance M-4050 4-channel) showed a top clean output for 100 Hz of 17.6 VAC. If you no longer wish to receive the call, please click the button to cancel your request. Roger, The circuitry of an amplifier uses its power supply's DC (direct current) voltage as the primary building block of its output. Butch, I think you're referring to an amp gain setting technique that uses a volt meter to attain a target output voltage that matches the desired output wattage. All settings on hu and amp set to minimum or 0 - volume at 75%. Since I think the subs will prob Be around 70-80hz LP, the mids 100hz HP and the tweeters 1.5k HP. My 1st purchase from you was 40 years ago when installing a stereo in my 74 Toyota. Does this mean I leave my amp gain at the lowest setting (4V)? It's through the magic of each manufacturer's design that it's done. ... Rockford Fosgate P300-10 Punch Single 10" 300 Watt Amplified Subwoofer 3) The speakers may be presenting 8-ohm loads to the amp. How long is Crutchfield's return policy? Just a great company, top to bottom. Then I turned up the receiver’s volume until I could see something bizarre happening to the wave’s shape. It's a focal amp, 70 watts rms x 2, and it's pushing morel maximo 6 components. I closed my eyes when I did this test, so no numbers were used to set the receiver’s top volume. Matthew, Perhaps checking out our Tuning your subs article will shed some light on the subject. Test tones also available as MP3 download from Amazon On Demand, Rhapsody, Google Play, and Spotify, labeled 3sixty. I swapped that speaker's wires to the left crossover, which is run by channel one, to rule that out. i installed Infinity Reference 6532ix's (coaxial) in the rear door of my 2016 Chevy truck and Infinity Reference 9630cx's (components with passivize crossovers) in the front. Regardless, can someone please please pretty please tell me once and for all what I'm suppose to do with the crossover on my amp when playing test tones to set my gains. This is so the gain would be set under real-world conditions. Or turn everything off? So attaining an output of 30 volts RMS through a 2-ohm load produces 450 watts RMS. Running the wires inside the is active. The P2D4-12 features a Dual 4-Ohm voice coil, 400 Watts RMS power handling, and can accommodate a grille insert using the included cast aluminum trim ring.

By simply replacing my P3 subwoofer with a 1-ohm Rockford Fosgate T1S1, I introduced an element that moves more air (greater excursion), handles more power, and (the initial goal) allows the amplifier to deliver its full 516-watt rating. Were you measuring peak-to peak? Then, I needed to use that receiver volume setting at that tone’s frequency to set the amp’s gain. Thomas, Just because a receiver's spec states it can put out a 4-volt preamp signal doesn't mean the signal is clean at that level. Using the lower-level signal means you'll set the amp gain a bit higher than you would with 0dB tones. What was going on was the power supply the receiver and amp used was 13.5 volts DC, about the same as a running car’s system usually provides, but the amp wasn't connected to the speakers and so wasn't loading down the power supply with the increased current demand of the speakers. Adam, If you want to squeeze every last watt you can out of your system and don't mind a little distortion, use -5dB test tones. Multiple Markets, MiTek Products Can Be Found In Over 80 Countries Around the World. This method can produce high-pitched, annoying, ear-drilling sounds that could hurt your hearing if you expose yourself for too long, and definitely will bother everyone within listening distance. Is it okay to play a 50 Hz test tone on my actual sub or will I damage it? Amp - Alpine PDR-V75 (gains set low - no "Bass boost" or HPF applied) Rockford Fosgate R2D2-10 Review. I also played a male singer, to see if it would be any different — it wasn’t. Page 5: 2-Channel Stereo/Mono Connections The short duration of the time it takes setting gain shouldn't endanger your speakers. I have an oscilloscope and understand the process. Basically I want to push all 1500 RMS or close to it but not sure you could do that without bass boost. If that's not possible (filters always on), then you'd start with high-pass filters set to their lowest frequency and the low-pass filters set to their highest frequency. I turned it up until I heard something go wrong with the vocal — it seemed thinner, not as bell-like, and harsher. Both are equalizers used to optimize the tone of the bass sound. If they can't perform as well as others I might be swapping these for something else. The Rockford Fosgate P2 12” subwoofer continues “The PUNCH” tradition. Set your receiver’s EQ presets and the amp’s bass boost to the way you normally listen to your music. It seems like they would just be going crazy as you do the test to set the gain, any way to mitigate this? And lastly, which is better? Okay so I've been running 2 Infinity Kappa 100.9 W's in a sealed box with passive radiators tune to 27 Hertz and it sounds phenomenal at 600 RMS each even though they're rated for like 375.

RFRB Rockford Fosgate P600X4 P600-X4 600 WATT Power AMP. I let the amp run it's auto tune with the gains all the way down and again using a pink noise tone over bluetooth from my phone. The 100 Hz tone rattled everything on the desk, so it was a little difficult to pick the buzz-point out of the crowd of reverberations. (The receiver’s top volume number was 62.) Ray, There are a few short-falls to using multimeter readings to set gain, instead of your ears. It lets you compare sonic characteristics between speakers. Any ideas why I am getting less than normal wattage readings? Surely these speakers should be able to take about 35% of HU volume with no eq boosts and the amp gains turned down. Rear speaker is full range. I tried using the "test tones by ear" method in my setup however, and didn't get very far. I do have one question though. It was a nice discovery! Highly recommend, customer support was excellent. Maybe it's just me I'm not sure, very well could be. So using test tones and listening to them through the car speakers does NOT damage the speakers? Logically it seems appropriate since theres lots of activity going on in that frequency range, normally played at higher levels than 35% HU volume. Instead of listening for distortion in music. Strangely channels 1 and 2 show voltages of 17.5 and 16.5 even though I set them both to high pass at the same level (180 as per mfr). Now i realise why my system sounded like rubbish when i set amp gains with receiver full tilt and no test tone Cd. Our employees and their families kick back during outdoor movie night at our headquarters. Download some test tone files or pick up a test tone disc and try if for yourself!
