Simple Volume Question

I have a simple question to ask. My amp was to loud and I bothered a friend to turn it down for me. Problem is he turned it down all the way. How would I turn the volume up on my amp myself? I have an idea of how to do it. But I just don;t trust my insincts.

Re: Simple Volume Question

Set the volume on your cd player to where you like it. Then rotate the knob labeled "gain" clockwise until you reach a volume you are comfortable with. Always stop if your sound becomes distorted and back the gain down.

So i have installed my amp, epicenter, all wiring is done, hace great ground.. But once i turn my car on to sound check everything starts fine but after turning up the volume a bit.. My amo goes into...

It sounds like you have your gain to high. best way to solve this is by turning the gain way down to - or lowest number , then turn everything on and upto the volume you desire, then slowly up the gain. also avoid using bass boost, I agree it sounds great but it puts strain on the amp and shortens life in the amp. with the bass boost off, you can adjust others (not the gain) to get bass.

Hope this helps

My pioneer gm 5300t amp cuts off at loud volume and will not kick back on until it is turned down and cools off, what is wrong with it?

You are over heating it,You have your speakers wired up for a lower,(OHM) Rate then the amp can handle, That why it cut out when you have it turn up

I have a alpine type r 12 in a seald box and want to know how to adjust my amp to sound right with metal and rock

hard to do because it is a VERY loud sub. turn the frequency down low on the amp so as just to be able to hear the kickdrum and bass line and turn the gain up just loud enough where you can hear it comfortably ( to your taste) at the loudest volume your going to listen to it at. if you do it right itll sound good. if you turn gain up past half or more it might blow your sub so be careful.

Why my amp shuts off when the volume is turn up and comes back on when lower the volume? I have 2 15 Q Power subs and Lanzar MXA3000D Amp

I used to own a Lanzar amp. I dont know if ours will be the same, but mine had a special safety feature. If i turned it up too loud it would go into it's safety mode and shut itsself down to protect the subs. You can bypass this security setting, but it is not recommended, as it protects your subs from a great deal of power.

either bad ohm load or over heat if the ohs on the speaker wires to the amp are lower than specified use in the manual it will act funny cause it is pusing harder than its meant to and if it gets too hot either bad location or bad amp you can try turning the gain down a little until the amp stays on constantly at high volume

Mic feedback. I sing on a shure beta 58 mic, into a 350 watt peavey amp, into 2 - 200 watt peavey speakers. My band is loud, and I simply cannot get my mic loud enough for them to hear me, without constant...

It sounds as though you are pointing the peavey at the band in a practice situation? If so make sure that each speaker is at about 60 degree angle to either side of the back of the mike (you facing the speakers), most mics reject feedback when the the user is directly in front of a monitor, but Beta 58s' tend to feedback more in that situation. Alternatively (if it is a practice room situation), why not place the speakers behind the band at 60 degrees each and turn to face the band.

Buzzing bass Amp combo

The problem you have mentioned is a common one with old sets, but it also occurs in new ones also, though not frequent. You can fix this just by changing the electrolytic filter capacitors in the power supply and sub filters on the amp PCB. The new capacitors should be of the same or higher voltage rating and same capacity rating as of the existing ones. And as it is such an old one, it is better to change all the electrolytic capacitors to avoid any further problems.

Amplifeir keeps turning off

HI K-****, Adjust your Gain setting to limit just enough so the amp does not go into Protect mode.
  1. Turn your Gain all the way down,
  2. then crank up the bass from your system.
  3. GRadually turn up the gain until you trip on protect.
  4. Turn the gain back a notch and your set for no more protect.
