It can be a number of things.

Bad ground, excess gain, excess number of mixer channels with no inputs, Make sure the mixer inputs you are going to use are the only ones that are up. Power supply noise- flourescent lighting noise, Clamp on ferrites on the power cords of everything can help reduce this. You can sometimes track the offending source with a battery powered AM/MW radio.

It can also be caused by going from a balanced output to an unbalanced input with some impedance differences.

The output of the UB802 is what is called active-balanced bridging into 10K. You're running it into some odd impedance unbalanced microphone input. Use a small 600-10k ohm transformer (Jameco Electronics) at the input of the CB, or order an inline XLR transformer from Shure, plus a 30-40dB Pad. Run the output of the UB802 at line level, and attenuate it just before it hits the microphone input through your custom cable. You could also eliminate the mic pre-amp in the transceiver if you were adventurous... mic pre-amps around RF, unless properly grounded, can be troublesome. And yes... invest in a pile of ferrite cores too to keep induced RF out of the mic circuit.

How to use the behringer 802 mixer and connect it to the computer


There are a variety of ways to accomplish this, but the two most common ways are:
  1. Purchase a BEHRINGER USB interface -- like a U-CONTROL UCA222. This will allow you to use the USB port for your sound In/Out. This will also require RCA cables to connect from mixer to UCA222 unit.
  2. Or...purchase a dedicated sound card (preferred) like an M-Audio Audiophile 2496 that can be installed in your computer (not for laptop). You will also need I/O RCA cables to connect.

The microphone preamps are different. The Xenyx has lower noise mic preamps.

Behringer mixer Eurorack UB802 is losing partial stereo signal in one channel. When I record (audacity software) I can hear both channels but displays one channel. Is it my computer's audio jack t


Sounds like the output cable from the 802 is not correctly pinned to your input on the computer. Fred is on the right track but you may need to take it a bit further.
It may also be helpful to use a Pro USB audio interface such as the Digigram UAX220v2 (line level version).
If you wish to use the computer's on board sound card consider an IHF/Pro interface that converts balanced audio to unbalanced , and the proper cables. Two 3-wire balanced 1/4-inch from the 802 to the left and right inputs of the interface (XLR Male), then RCA (Red and White) to a 1/8-inch TRS Plug cable onto the the computers audio input.
Henry Engineering's Matchbox HD comes to mind.
Good Luck.

Behringer ub802 mixer is buzzing even when no input when i hook my head phones into the headphone jack and main output jack


If it buzzes when you have no inputs AND no output leads connected, there is a problem with the power supply... HOWEVER if you have used UNBALANCED output cables instead of the REQUIRED TRS BALANCED output cables, it is possible the noise is being driven backwards and that is what you are hearing. Note that at full gains, there often is a tiny bit of noise, usually hiss. Also make sure the supply is powered from the SAME receptacle as the equipment this drives such as an amp or powered speakers.

Changing the output Jack on 1985 Peavey Dyna Bass


If this has active circuitry, one of the wires is the cutoff for the power supply from the battery. The other two are black for ground and either white or red for signal.
