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 oers 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 ¼" 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 eect 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 eects. The result are extremely musical equalizers which, unlike simple
equalizers, cause no side eects 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 lters that increase or
decrease all frequencies above or below their cut-o frequency. The cut-o
frequencies of the upper and lower band are 12 kHz and 80 Hz respectively.
The mid band (Q802/1002/1202USB) is congured as a peak lter 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 lter at 80 Hz designed to eliminate unwanted low-frequency
signal components.
