STATUS-LED LINE
Displays the level status of the Master 1 and Master 2 line outputs. If the green status LED lights up, the output signal of the corresponding
line output Master 1 or Master 2 is output at line level (e.g. for the line input of a power amplifier). If the green status LED does not light up,
the output signal of the corresponding line output Master 1 or Master 2 is output with a 20 dB attenuation (e.g. for the microphone input of a
mixer). First select the line output for which the output level should be changed by pressing the MASTER rotary encoder and holding it down
for approximately 2 seconds, then select the line output (Master 1 or Master 2) with the rotary encoder (status LED flashes red) and confirm
your selection by pushing the push-button. Press and hold the press button of the MASTER rotary encoder for approximately 2 seconds and
turn the rotary encoder until the status LED LINE flashes red.
Now if you press the push-button of the MASTER rotary encoder again, the output is switched to the output level of either line or the
reduced level and vice versa. If the push-button is not pressed within 10 seconds, there will be no change and the LED stops flashing.

THRESHOLD
Input channels that have a signal level under a certain threshold level can be muted with this function. This means that the transmission
of a channel's background noise, feedback or unwanted comb filter effects from other active channels are effectively suppressed and
intelligibility of speech is improved. Input channels that have a signal level over a certain threshold value are automatically activated. The
rotary encoder is deactivated for setting the threshold value during automatic operation (status LED no. 32 = green). The threshold value
is automatically adjusted to the volume of the surrounding sounds. The threshold value can also be set manually and individually for each
of the 8 channels. Set the threshold value in order that background noise does not automatically activate an input channel, but that the
activation of a channel speaker etc. is possible. Switch the THRESHOLD function to manual (see point 32 STATUS LED THRESHOLD AUTO
/ MANUAL) and briefly press the push-button of the desired channel (channel mute, 15-segment status LED flashes). Press and hold the
push-button until one of the status LEDs ("LINE" or "ACTIVE") under the operating element of the corresponding channels flashes red, then
with the help of the THRESHOLD rotary encoder, set the threshold value between 0dB and -60dB as desired (please note the 15-segment
status LED THRESHOLD no. 30, all LED segments off = 0dB, all LED segments on = -60dB). Then briefly press the push-button of the
corresponding channel in order to confirm the setting and deactivate the muting. If there is no input for approximately 10 seconds, the
muting will be automatically deactivated and the currently set value remains the same.
