2.1.1 Microphone and line inputs
MIC
Each mono input channel offers a balanced
microphone input via the XLR connector and also
features switchable +48 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.

you activate the phantom power supply to

to your loudspeakers. Please also note the

Each mono input also features a balanced line input on a '/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!
GAlN
Use the G A l N 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.
2.1.2 Equalizer
All mono input channels include a 3-band equalizer,
except for the 502, 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 k15 dB.

This means that the mix between dry signal and effect
remains at the level determined by .the channel' s
aux send, irrespective of the channel fader setting. If this were not the case,
the effects signal of the channel would remain audible even when the fader is
lowered to zero.
PAN
The PAN control determines the position of the channel signal within the stereo
image. This control features a constant-power characteristic, which means the
signal is always maintained at a constant level, irrespective of position in the
stereo panorama.
LEVEL
The LEVEL control determines the level of the channel signal in the main mix.
CLIP
The C L I P LED' S of the mono channels illuminate when the input signal is driven
too high, which could cause distortion. If this happens, use the GAlN control to
reduce the preamp level until the LED does not light anymore.

marked "L" (left) is used, the channel operates in mono.
The stereo channels are designed to handle typical line

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 (802/1002/1202) is configured as a peak filter with a center
frequency of 2.5 kHz.
