SIGNAL INPUT / OUTPUT
12
Two-colour illuminated digits for signal detection and clip display.
INPUT: As soon as an audio signal with sufficient level is present at an input channel, the
corresponding digit lights up white. As soon as one of the digits lights up red, the corresponding
input stage is operated at the distortion limit. In this case, reduce the channel pre-amplification
GAIN or reduce the level on the playback device so that the digit no longer lights up red.
OUTPUT: As soon as an audio signal with sufficient level is present at an output channel, the
corresponding digit lights up white. As soon as one of the digits lights up red, the corresponding
output stage is operated at the distortion limit. In this case, reduce the level on the source player
so that the digit no longer lights up red.
LOCK SYMBOL
13
The editing mode can be locked against unauthorised editing. Press the encoder for about
10 seconds to activate the lock. Ignore the fact that the editing mode is activated after about
3 seconds. Now the lock symbol flashes for a few seconds and then lights up permanently and
only the status query of the input channels can be carried out. To deactivate the lock, press the
encoder again for about 10 seconds.
AIR VENTS
To prevent damage to the device, do not cover the ventilation openings on the left and right
sides and on the top and bottom of the device and ensure that air can circulate freely. Covering
the ventilation openings on the top or bottom of the enclosure when mounting it underneath
or on top of a table is not critical, as the cooling provided by the ventilation openings on the
remaining sides is sufficient.
Tip: Preferably use balanced audio cables for wiring analogue line inputs and outputs.
