To achieve the optimal balance between the S/N ratio
and the dynamic range, set the level so that the PEAK LED only
lights up in the presence of signal peaks. The 10 to 60 scale
indicates MIC input adjustment level; the -20 to 30 scale indicates
the LINE input adjustment level.
tone controls to adjust the treble, mid, and bass
range of the signals. The tone control is flat with no equalisation
when the knob is in the central position (0); frequencies are
gradually attenuated by turning the knob counterclockwise and
enhanced by turning it clockwise.
adjusts the level of the signal on the channel to send to the
MON jack output. The MON output signal is subject to the action of
the tone controls but it is not affected by the volume control.
serves to send the channel signal to the digital effects
processor, in accordance with the volume control; this feature
makes it possible to add an adjustable effect component on each
channel.
the pan control adjusts the position of the sound in the stereo
stage so that the stereo image can be modified constantly as
required. Turning the knob to the left or right alters the proportion of
the two signals on the left and right channels. With the knob turned
fully in one direction the signal on the opposite channel is reduced
to zero.
adjusts preamplification of signals supplied on the XLR and
Jack inputs, optimizing the level for correct operation of the channel
input circuits.
adjusts the output level of the signal to be sent to the main
controls. In normal circumstances the best performance of the
channel circuit is obtained with the knob set to approximately the ¾
position and with the Gain adjusted in such a way as to obtain the
required level.
serves to activate/deactivate the channel.
this LED illuminates when the signal after the equalisation
stage is close to the saturation threshold: in this case the problem
can be remedied by means of the GAIN control.
electronically balanced XLR connector socket designed for
the connection of low level signal sources such as low impedance
microphones.
balanced and unbalanced Jack connector inputs.
Electronically balanced, designed for connection of high level
sources such as keyboards, guitars, etc. This input also accepts
mono jacks; when a mono jack is inserted the signal is
automatically unbalanced.

balanced input sockets for stereo Jack connector;
provide the facility to connect mono (using only the L-mono socket)
or stereo sources (using both sockets) to the mixer.

STEREO sources, such as, for example, CD players,
keyboards, etc. include both a left and a right channel which
shall necessarily be managed by controls allowing to adjust
both signals at the same time.
This is why stereo input channels have been added: basically,
they combine two mono channels unifying their controls.
Instead of the PAN control, the stereo channels feature a
balance control (BAL) allowing to balance possible level
differences between the signals of the two channels.
