AUDIO MATRIX

Each of the 8 input channels (INPUTS 1-8) can be individually routed to the two line outputs Master 1 and 2 using the audio matrix of the
AM8 automatic mixer (M1 and M2). To select which input channel should be routed to which of the two line outputs, and which one should
not, simply click on the appropriate button. When a channel is routed to an output, the corresponding button is highlighted in blue (CHANNEL
OPEN), otherwise, it will be greyed out (CHANNEL CLOSED).

THRESHOLD
Input channels with a signal level under a certain threshold value can be muted with the assistance of 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 ("AUTO" button highlighted yellow).
The threshold value is automatically adjusted to the volume of the surrounding sounds. Manual setting of the threshold value (-60 dB to 0
dB) for automatic activation of the input channels is done separately for each channel ("CH SYNC" button greyed out) or for all channels
simultaneously ("CH SYNC" button highlighted yellow). If you click on "MAN" ("MAN" button highlighted yellow) and then select the desired
channel and threshold value in the drop-down menu, background noise will not automatically activate an input channel, but activation of a
channel by a speaker etc. is possible. Set the hold time of the activated channel by clicking on "HOLD TIME" in the drop-down menu and
then selecting the value of your choice (0 - 2000 ms). The channel remains active for the duration of the set hold time, even if the audio
signal falls silent. This means that a different channel can only become active after the end of the hold time.
