AES Inputs and Outputs
The 4 Series units have a full AES implementation built in as standard. This allows the unit to both receive digital audio
directly, and to transmit digital audio on to other devices. The switching of input and output can be performed
independently, and the inclusion of sample rate converters on the inputs allows the unit to accept sample rates from
32kHz up to 192kHz.
AES Input
Input selection is via a recessed switch on the rear panel of the unit, between input D and output 1. A red LED inside this
aperture illuminates to show that the AES digital inputs
have been selected.
A complimentary LED on the front panel below the
PCMCIA card also illuminates. The switch controls the
rear panel LED directly, whilst the front panel one is via
the processor, allowing it to relay a little more
information.
If it is flashing, this means that AES inputs have been
selected but have not locked. Once a stable AES signal is
being received, it will be permanently illuminated.
The AES inputs are marked on the rear
panel –
for channels A & B use input A,
and for channels C & D use input C.
AES Output
AES outputs are selected through the AES menu:
