Output Mix Matrix Selection Using The Front Panel
DIPSwitches
The OUTPUT MIX front panel DIPSwitches are
concealed behind the screw panel located on the front
of the unit and they decide which input channels are
mixed to which output channels. There are 4 banks of
DIPSwitches, each representing an output channel.
To mix an input to that channel, simply lift the DIPSwitch for the desired input channel. In
total, 4 mono channels can be mixed together on each mono output channel.
This allows many mixing configurations and maximum flexibility. Adding to that, mixing
can be achieved between all the different input types at all sample rates. See page 7 for
applications for the product using different matrix settings.
INPUT 1 & 2 Source Select Button, Indicators & Input Presence
LEDS
This button allows you to select which of the digital input sources
you would like to use. The three LEDs above the button illustrate
which source is selected. The button also indicates whether the
input is locked - it flashes green and red if the input is unlocked
and is unlit when locked.
The bicolour LEDs, marked ‘1’ and ‘2’ , show input presence and give an indication of the
input level using the AES digital standard with the following colours:
-INF < -52dBFS = OFF
-52dBFS < -3dBFS = GREEN
-3dBFS <0dBFS = ORANGE
