Setting amplifier using multimeter

how to use a multimeter to set an amplifier using AC voltage reading at the speaker terminals

[@justScrollin0627]

Saw a few people asking about if having a "bass knob" which actually just adjusts the gain on your amplifier with max on the "bass knob" being whatever your gain adjustment is set to ,all the way down to the gain setting to zero on the minimum side of the "bass knob.". If you set your gain using this method that he showed...just set your " bass knob" to the MAX setting while adjusting the gain on your Amp using the multimeter square root method he showed in the video..What that does when setting the " bass knob" at max is assuring that you can never send a clipped signal because it was at max when you set your gain on the amp... you can go lower whenever you want on the fly depending on song choice but it ensures that you can never go to high...hope this makes sense to those who asked...👍

[@Whitetrashweldr]

not always, some knobs adjust BOOST by db at certain frequencies. that's dangerous and asking for clipping. gotta watch out

[@justScrollin0627]

@@Whitetrashweldr not familiar with what you are talking about...Any "bass control knob I have encountered are basically just an adjustment on how many volts the amp puts out all the way up to whatever setting you have your gain adjustment set to on your amp...The "Bass EQ" setting on the physical amp usually does the function you are speaking of and is best to just leave off so you don't send a clipped signal...Not saying they don't exist....but is definitely not common place for a "bass control knob...

[@justScrollin0627]

As far as I know the final output that an amplifier will put out is whatever you have your gain adjustment set at...That is why its very important to start from head unit and work your way all the way back to the amplifier for proper signal setting..Finding your clipping point from head unit first...then adjusting any Line Out Converters,Line Drivers, EQ's ect to just before clipping....then lastly the Amplifier Gain Setting to just before Clipping at Max everything...doing this ensures that turning your system up to absolute max will not harm anything because its all been set properly....As well as using the subsonic feature on your amp(if available) because this ensures that your subs won't "bottom out" at extremely low frequencies that 1)your sub isn't designed to produce ..2) If running on a ported or vented enclosure going to far down below the tuning frequency of your enclosure causing your sub to surpass its mechanical throw...Finally the "Boost Boost or Bass EQ function is the most dangerous setting to use because it bypasses the settings at certain frequencies to "boost" the bass which will send a clipped signal and cause damage..That feature is useless in most cases and should be taken off of amps in my opinion...if everything is set properly and you arent satisfied with the bass output......Get equipment that can produce what you desire...taking a short cut with "Bass EQ" Or "Bass Boost" will leave you with damaged equipment almost always....of course this all is just my thoughts and opinions but have yet to fry an amp or sub..👍

[@Whitetrashweldr]

Cmon man if you’ve ever read an owners manual u would know what I’m talking about. Even power series from RF come with a EQ knob. If u want a gain knob buy a rca in rca out gain adjustment knob. But hey 🤷🏻‍♂️

[@justScrollin0627]

@@Whitetrashweldr dude we are talking about two different features...any type of " Bass EQ" function on an amp should be left off! Whether it is a knob adjustment or on the amp itself!!! A so called "bass knob" is basically a gain adjuster and is perfectly okay to use AS LONG AS when setting your GAIN on the amp is done correctly...STOP ✋ trying to argue..if you are using a "bass eq" knob ....you are a fool...because its the same thing as the bass eq or "bass boost" on the amp...

This man reminds me of my big homie back home. the way he explains something in great detail and the tones when it comes to certain details almost as if he’s beating that shit into your head. What I’ve spent the last couple weeks trying to figure out across forums, videos etc.. has taken 27mins to register. Thank you.

[@anonymousperson7889]

What exactly are you trying to figure out though? Does your system sound good? Did it before? That's all that matters. I have put systems together that were cheap $60 to $100 amps pushing entey level subs, with low budget mids and highs and systems where the subs alone cost $700 a piece and the component speakers were close to the same. They all sound amazing without ever touching a multimeter. Most of us are never entering a sub competition and nor do we want to. We want to listen to music, feel the bass and have a good time. Just roll with a few simple rules/policies.....never push your amp to 100% gain always over power what you want to use and never push peaks with your speakers and subs. No need to blow anything or even the push limits on anything and it will last forever. Hope you are enjoying yourself some bass brother ❤ Keep thumping!

[@alexandernewsome2505]

Oh hell yeahh ! Im subscribing. Nobody i have seen do this as detailed as you man. Right on. Thanks you!

[@puertorockboxinggym5771]

Simple and accurate instructions. I know how to do this but wanted to see how well the instructions were told and this video keeps it SIMPLE AND ACCURATE ❤

[@markg5916]

I've been setting my gains like this for years but I do something at the end a little different. The 40 hertz constant load isn't what you will be using as a signal for day to day use, it's music. So being that music is far less stressful on a amp than a tone it seems to make sense that you can squeeze a little more of of the tune on music. This is my procedure. After I have my gain set same as the procedure in the video I then play a few bass heavy songs that I know play good in my system and I watch how close the voltage on the multimeter gets to my target set voltage. Usually it isn't hitting the target voltage so I add some gain on music till I see my peak voltage hit my number. Even if after three or so songs, if I see the peak voltage peak higher here and there, it's just for a fraction of a second at a time. I have had success for a decade or so doing this. This really requires you knowing your system and what songs play the best. If your new to it I suggest just following the video only. What do you think?

[@flowmaster2010]

Sounds smart dude, because there is maximum voltage the app can hit and also the running voltage it likes for continuous.

[@It-b-Blair]

Idk man, @13:47 is what I was thinking when I read this… especially since different sources can have varying fidelity, it could easily lead to clipping, maybe inaudible, but it’d still be there

[@marcus05011993]

Makes a lot of sense because once in a while I'll do the math and set my voltage at what it says it should be I have two VXF 12s and two RP 2000 amps subs are wired to 2 ohms they each got their own amp they're getting 1400 RMS so math says to set it at I think like 53 volts and I always end up setting it to 53 volts and I spent a lot of time on back roads testing my system and whatnot and it seems my system sounds better at 64 volts and I have an oscope and everything and when I usually set it to the 53 volts I do everything the right way and turn all the filters off and I always end up studying it to the suggested voltage and then not liking it and turning it up to that sweet spot I have my subs on my backseat of my Dodge ram quad cab so I mean I can hear every little noise coming from the subs and even at the 64 volts I seem to not have any noises or problems but I also whether I have it at the 53 volts or the 64 I usually have my EQ set to flat I don't have any bass boost on or anything

[@It-b-Blair]

@@marcus05011993 trip, I just set my two 18”s in my Silverado to 80v for 1600rms with the bass mechanic tracks. Then my bass knob showed clipping on some heavy songs, I tuned with those tracks and it ended up being turned down to 60v on the test tones so no matter what played I didn’t get clipping. It’d be cool if tracks had all the same levels, but everyone mixes differently, and none of the electronic components account for it, they just process and send the signal along. I didn’t hear it clip, but the knob was flashing red like crazy.

I use this method when dealing with a lower rms subwoofer and a higher powered amp.. this sets the amp perfectly to put out enough watts fora particular sub so you can ensure it’s not being over powered. I also use the SMD DD-1 to find my just before distortion level quickly. Both work in conjunction with the same possible outcome of setting the gain correctly. Explained well MBE

[@fishrrelaxing9361]

This is how I set all my amps.. but it’s good practice to measure your rca as well.. especially if using a LOc.. not all LOc are equal and give a clean signal but a lot of clipping can be sent to the amp.. for example I use the kicker which has been shown to supply 6.5-7 clean wo clipping.. as I can measure clip I set mine to 6v to be safe then I work on the amp setting. The amp is the easiest thing to set.. but if you have a dirty signal going to the amp you’re only going to be amplifying that signal no matter how b good the amp is set… Also on my cue system I actually set bass to max for adjustment but that’s cause I use the bass setting on the slide unit as a bass knob but you can only do this with boss or HK systems as they have internal circuits that adjust column to eliminate clipping..

1 kHz should be used for the mids and highs when setting your amps running your front stage and rear speakers.

[@PhiMobileSounds]

@A. Melbs It’s probably in your manual. If you look at the layout of your 4ch amp and compare the crossover capability, you will want the channels capable of processing a signal and ohm load you can achieve on those two channels. Definitely consult your manual to see with the amp can support bridged. Use 40hz on the lows and continue to use the 1kHz on the left and right channels mids and highs. Good luck.

[@dcaudio1]

MBE baby that was a freaking great video...i always do my tuning by ear and im betting im close but i am going to do this tomorrow. For reference i have a Audio Control LC 1.1500 which bench rest at about 1750 at 2 ohm...this amp is not 1 ohm stable. My speaker setup are Morel tempo ultra components front and rear on a Audio Control LC 4.800 rated at 125 watts times 4 channels. My calculation from this video is 53 volts. My weakest link in my system is the stock head unit going into a PAC 4 volt out with low level signal. I can say without hesitation the Audio CONTROL LC2i Pro was far superior for a fraction of the cost $139 Crutchfield) than the PACGM PRO ($450) . My stock head unit (2015 GMC sierra stock Bose head unit) is junk....i need to get that past 3/4 to get voltage to kick in. between 3/4 and 7/8 is where it finally kicks in. For those reading this get the LC2i Pro it can put out 9 volts from high or low level inputs.....much better unit IMHO. For reference i run several systems but my current subwoofer system are two JL Audio 10w3-4 wired to 2 ohm to the amp. tuning is 32 hertz on a ported enclosure i built. sounds very very smooth and clean and very efficient. I change boxes frequently so i have a excellent reference for efficiency, versus power hungry versus box rise.....it all makes a difference....

Just took my time. The quote, with everything listed for $434, I got it down to $50! I only allowed them to run my signal from my HK factory sub.

When setting your gains you want to put your multimeter red lead to the positive speaker lead on amp and the black to the negative speaker lead on your amp and lightly tighten them up. Your will leave them hooked up to your amplifier while you are running your hz test tone and setting your gains. Make sure your Multimeter is set to AC voltage (not dc). Once the gains are set and matched to the proper power level you are looking for then you will disconnect your Multimeter leads and connect your speaker wire back up. Your Lc2i is just a line output converter so before you set your gains look up your amps specs and see what the supposed input voltage is and you can set your the loc to get a clean low level power to your amp. I think the lc2i range is like 2 to 9 volts but you will have to look it up on audio controls website. When it comes to your amp you will still have to use your hi/lo and make sure all your amp settings are correct. Remember bass boost is your enemy

@@michaelraykinney gotcha thanks bud, so for the Hi/Lo button on my amp, should I click it in? Should I set it to high or low? I have it set currently to the Hi

Hello, what would be different on a multiple channel amp? Also, how did you connect iphone to amp? Sorry if it’s a dumb question just not sure.

Question, will the voltage that supplies your amp affect the settings of the Gain?

[@weshowell7977]

Yep

Just wanna make sure I’m doing this right I have 2 subwoofers 300 watts each side so total 600 watts and I’m doing 2 ohms so would I do 300 x 2 or 600 x 2

Its kinda cute and dry but some set gains with the sub connected some use sqr rt of the amp some the speaker me for instance have a salt 6 with a nightshade v6 15” which is 3000rms so which number do i use 6000 from amp or 3000 from sub
