2.  Control Elements and Connectors

This chapter describes the various control elements of your mixing console. 

All controls, switches and connectors will be discussed in detail.

2.1  Mono channels

2.1.1  Microphone and line inputs

Fig. 2.1: Connectors and controls of mic/line inputs

MIC

Each mono input channel offers a balanced microphone input via the XLR 

connector and also features switchable +48/+15 V phantom power supply for 

condenser microphones. The XENYX preamps provide undistorted and noise-free 

gain as is typically known only from costly outboard preamps.

◊ 

Please mute your playback system before you activate the phantom 
power supply to prevent switch-on thumps being directed to 
your loudspeakers. Please also note the instructions in chapter 
2.3.5 “Phantom power and LED displays”.

LINE IN

Each mono input also features a balanced line input on a 1/4" connector. 

Unbalanced devices (mono jacks) can also be connected to these inputs.

◊ 

Please remember that you can only use either the microphone 
or the line input of a channel at any one time. You can never use 
both simultaneously!

GAIN

Use the GAIN control to adjust the input gain. This control should always be 

turned fully counterclockwise whenever you connect or disconnect a signal 

source to one of the inputs.

COMP

Use the COMP knob to adjust the amount of compression effect on the channel. 

Compression limits the dynamic range of the audio source, which can help vocals 

cut through a mix better, for example. Turn the COMP knob clockwise until the 

adjacent LED occasionally lights during speech/singing.

2.1.2  Equalizer

All mono input channels include a 3-band equalizer, except for the Q502USB, 

which is equipped with a 2-band EQ. All bands provide boost or cut of up to 15 dB. 

In the central position, the equalizer is inactive.
The circuitry of the British EQs is based on the technology used in the best-known 

top-of-the-line consoles and providing a warm sound without any unwanted 

side effects. The result are extremely musical equalizers which, unlike simple 

equalizers, cause no side effects such as phase shifting or bandwidth limitation, 

even with extreme gain settings of ±15 dB.

EQ

The upper (HI) and the lower band (LO) are shelving filters that increase or 

decrease all frequencies above or below their cut-off frequency. The cut-off 

frequencies of the upper and lower band are 12 kHz and 80 Hz respectively. 

The mid band (Q802/1002/1202USB) is configured as a peak filter with a center 

frequency of 2.5 kHz.

LOW CUT

In addition, the mono channels (Q1002USB and Q1202USB) are equipped with a 

steep LOW CUT filter at 80 Hz designed to eliminate unwanted low-frequency 

signal components.

2.1.3  FX sends, panorama and level adjustment
