3.1 Top Panel Overview

This section details the controls and connectors located on the top panel of your UB802 mixer.

Sary 1: Ambony midina view of the Behringer UB802 mixer's control panel. This image displays the microphone and line inputs, gain controls, 3-band EQ sections, FX send, pan/balance controls, channel level knobs, main mix section, phantom power switch, and level meters.

1. MIC IN (Channels 1-2): XLR inputs for connecting microphones. These inputs provide +48V phantom power when activated.
2. LINE IN (Channels 1-2, 3/4, 5/6): 1/4" TRS inputs for connecting line-level sources such as keyboards, drum machines, or other audio devices. Channels 3/4 and 5/6 are stereo pairs.
3. GAIN (Channels 1-2): Adjusts the input sensitivity for the microphone and line inputs. Use this to set the optimal signal level before it reaches the mixer's internal processing.
4. EQ (AVO, ANTENA, AVY): Three-band equalizer controls for shaping the tone of each channel. HIGH affects frequencies around 12 kHz, MID around 2.5 kHz, and LOW around 80 Hz.
5. FX Send: This knob controls the amount of signal sent from the respective channel to the external effects processor connected to the FX Send output. It is a post-fader send.
6. PAN (Channels 1-2): Positions the mono signal within the stereo sound field (left to right).
7. BAL (Channels 3/4, 5/6): Adjusts the balance between the left and right signals of the stereo input channels.
8. LEVEL: Adjusts the output volume of each individual channel to the main mix.
9. PHANTOM POWER (+48V): A switch to activate +48V phantom power for condenser microphones connected to the XLR inputs.
10. CLIP LED: Illuminates when the input signal is too high, indicating potential clipping or distortion. Reduce the GAIN control if this LED lights up frequently.
11. LEVEL METER: LED indicators displaying the overall output level of the main mix. Aim for levels around 0 dB during normal operation.
12. MAIN MIX: Controls the overall output volume of the stereo main mix.
13. 2-TRACK IN/OUT: RCA connectors for connecting external recording devices or playback sources (e.g., CD players, tape decks).
14. CONTROL ROOM/PHONES: Output for connecting headphones or control room monitors. The level knob adjusts the volume for both.
