PSU status – two bi-colour LEDs confirming
the current status of each PSU. The LEDs are green
in normal operation and flash red if a PSU fault
condition is detected.
MADI Data display – a 2x16 character LCD
providing interrogation of embedded information
such as MADI frame data, AES channel status bits
and audio data; plus the provision of menu features
for unit configuration.
Menu control – Rotary encoder with push
action to navigate through the MADI Data display.
Channel Pair Select – Rotary encoder with
push action to navigate across all 32 AES channel
pairs. The selected channel pair is indicated by LED
(12) illuminating under the selected channel pair
number. Pushing the encoder will return selection to
the first channel pair.
Volume – Rotary encoder with push action to
control front panel speaker and headphone volume.
It also controls the analogue line level outputs on the
rear panel [13] and [14]. Pushing the encoder will
mute the speakers and outputs.
