Channel 1 static and lack of performance

Channel 1 is low on volume and when i turn the gain up and down its gets staticky(sp) and inconsistant. It gets the quietest at about half way up. I know its just channel 1 because i switched the speakers and it changed with the switch. It seems that sometimes it works fine and other times it does this. It is a little dirty from and outdoor event but it had been working fine since til just recently. I also tried pushing the reset button but it didn't seem to do anything at all.

The potentiometer (volume control) is probably dirty. Open the amp and find the "pot" connected to that volume control. You should be able to see small opennings where you can spray electrical contact cleaner inside. Give the knob a few turns and try it out. If it gets better but not perfect, repeat. If several attempts don't eleminate the problem, the pot will most likely need to be replaced. Contact cleaner can be found at any electrical supply store such as Radio Shack. Be sure to use one that says no or zero residue. I use a product called Electrosolve.

When setting up xr8600 is it best to start mains and monitors master at 0DB?

1. Turn the main and monitor volumes all the way down (off). Plug a cd player into channel 9/10 and play a track of music of your liking. With the main/monitor volumes still off, adjust the gain on 9/10 until the clip light turns on, then back it down until the clip light just turns off. Put the channel volume at 12 o' clock.
2. With the music still playing, turn up the mains to the desired listening level first, and then adjust the graphic eq until the music sounds good in the room. Remember or mark the position of the volume control. Do not use the channel eq on 9/10 for music that has been mastered properly, leave the eq flat. Once this step is completed then you have now set the main eq.
3. Repeat the same for monitors. Turn off the main volume and then bring up the monitor main volume to the desired level first, then set eq. Now your monitor eq is set properly. Remember or mark the position of the monitor volume.
4. Set up microphone - plug a mic into channel 1 with volume all the way down. Speak or sing into the microphone and adjust the GAIN until you see the clip light, then back down a litttle on the gain. Put the monitor and main volumes back up to the mark from step 2. Now adjust the volume and monitor send on the mic channel to the desired loudness first before adjusting the mic channel eq. Use subtractive eq method to minimize distortion and feedback. ...i.e. if the mic is bassy then turn down the lows, do not ADD highs. If the mic needs bass, turn down the highs.

I have 2 12in kenwoods and a 1200 watt pyrimade amp, how can i hook these up to be the loudest

1st have your subs facing inwards towards the front of the car, not facing out the boot, This creates a better bass.

Wire 1 sub to one channel and the other sub to the other channel.

Turn down your gain as low as possible and then power everything up.

turn volume to desired loudness and then start turning up the gain slowly, if distorts a little turn in back down a notch.

avoid using bass boost, I agree it sounds great but it puts more strain on your amp and shortens its life.

after sorting out your gain, tweak all others until sound is bassy and clear with no distortion.

If you would like to use bass boost, turn on bass boost first, then up your gain etc.

Behringer GTX30 guitar amp. Channel switch setup: clean, but I can hear a little return of distortion, coming from the overdrive channel. This happens only on the speaker. Using the headphone everithi

If you are using headphones, then I'm guessing you are practicing and running the amp as quietly as possible while still able to hear it. Unfortunately, most channel switching guitar amps will have a tiny bit of bleed-through from the other channel when turned all the way down and listened to at close distance from the speaker. And yes, using a mechanical switch or relay to switch the connection from one channel to the other would mostly eliminate this, but due to the high amount of signal gain in guitar amp preamp sections, this type of switching causes very loud pops and other unwanted noise when switched. The amps are made with either photocell (optical) resistors or reverse biased transistors or op amp chips to switch channels. These are 'softer', partially because they don't fully turn off when in the off state(or fully on either). This creates bleed through, but it is better and easier than a CRACK THUMP POP!! every time you stomp the channel switch pedal. Amps are designed to be used at output levels generally much louder than a dorm room at 11:30 pm, and at stage volume in a club, the channel bleed is so far below audible, it is never heard by anyone. That's just the way it is.

Why would my car stereo sound staticky when i give it volume'',it was not like that earlier

first adjust the fade and balance, checking each speaker for this issue. if they all continue to cause static when turning up the volume, then it is either the connections are crimped poorly, speaker connections are not secure at speaker or just a faulty volume control knob

Amp volume problem

Sounds like you have a bad or dirty gain potentiometer. Try turning the gain up and down with the volume at a moderate level. If u hear static, it is possible the potentiometer is bad or dirty. Replace with one of the same value and see if that solves your problem.

Pcchips A13G+ motherboard sound issues

You may not have a choice. The jack could be loose or have a bad solder joint. If the microphone is "staticky" on this system but not on another, then increasing the volume will only increase the static.

You can try a condenser microphone. Condensers require their own power (battery) and output a MUCH higher signal. High enough for the Line-In jack.

If you are using the microphone for voice chat or internet phone or gaming or similar, I STRONGLY suggest a USB headset, such as you can get from Logitech. You wouldn't believe the quality difference.

Speaker problems

You've probably tried this, but when you do the channel test you can turn the volume up or down on whichever speaker is currently being tested (the static). Maybe your speakers have been adjusted somehow.

Channel 2 volume is very low

You can check if channel 2 is blown by switching around your RCA plugs. If you are using the speaker wires as high power inputs you can change them. I.E. swap the left channel with the right one. I assume you checked the gain control on the amp. If channel 2 works with channel 3's inputs then its your head unit or the wiring. If you are lazy take the amp to a car audio store and ask them to bench test it for you. Hack
