Signal routing of the Extension Card
As soon as the Extension Card is installed, it is automatically de-
tected by the device and the Status LED on the module will light up
green. Now you can allocate the Extension Card to the desired out-
puts in the “AUX / HEC (MEC) Routing” matrix.
Several new features are visible in the DSP PC-Tool after installing
an Extension Card.
The optical SPDIF output of the HEC / MEC AUX IN module
The installation of the Extension Card adds as well an additional digi-
tal optical SPDIF output to your device. This output allows to transmit
any unprocessed input or processed output signals to other devices.
A new matrix “Digital Output Routing” appears in the “Input and Out-
putConguration”pageinwhichyoucanmakeyourdesiredsettings.
The digital output delivers an uncoded stereo PCM signal with either
96 kHz / 24 Bit or 48 kHz / 24 Bit, depending on the sampling rate of
the designated device.
