Input VU-meter
The input VU-meter lets you visually monitor the input signal level, having
indications for –30dB, -24dB, -12dB, -6dB and –3dB. Furthermore, LIMIT and
CLIP indicators are provided. Apart from normal operation for input level
monitoring, digital clipping is also shown here. If the CLIP led lights up but the
LEDs below do not, this means that the digital audio signal is clipping (DSP) and
not the analogue input stage. This may happen if inadequate EQ or excessive
gain is applied to any of the outputs.
Output VU-meter
The output VU-meter lets you visually monitor the output signal level relative to a
trigger threshold adjustment. If a +4dB signal is sent to an output with a trigger threshold of
0dB, the –6dB led will light up.
MUTE Buttons
By pressing these buttons (one for each output channel) the selected channel is
muted. If the output is muted, the associated led next to the button is lit.
Rotary encoder wheel
By turning the encoder wheel clockwise or counter-clockwise,
parameters and values shown on the display can be incremented or
decremented. The encoder wheel also features a push-button function.
At each press, the parameters for the next input or output channel are
accessed cyclically. By pressing and simultaneously turning the wheel,
inputs and outputs can be accessed more quickly.
