Logical control mostly used on control outer inputs and outer outputs:
Control inputs (IN): when external control input high level to the pin of certain channel, the channel gate
will be compulsorily open; when external control input low level to the pin of certain channel, the channel
gate will be automatically tested; the gate will be open only when AF signals get through it.
Control outputs (OUT): when the microphone is open, the pin of this channel will output high level.
When the microphone is mute, the pin of this channel will output low level.
06 Operation Instructions
DAM-800 8-channel digital automatic mixer with 60-section digital potentiometer design, each digital
potentiometer can select the corresponding function.
Such as CH1, as follows
Rotate the encoder switch to adjust the volume of AF input, press the encoder switch, then LED light will
twinkle，it indicate enter menu selection mode，then rotate the encoder switch to choose corresponding
function.
For example:
The LED light is twinkle, it indicates select “on” function, then press the encoder switch again, the “on”
function is enabled. If the “on” green light is on, it indicate the priority speak mode is enabled, if the “on”
light is off, it indicates the automatic test mode is enabled.
