100Hz and 1kHz Setup Tone at
48kHz sample rate to All Outputs
A 100Hz tone at -20dB will be sent to all left
channels outputs.
A 1kHz tone at -26dB will be sent to all right
channel outputs.

to All Outputs
A 1kHz tone at -40dB will be sent to all
outputs.
100Hz Setup Tone at -6dB
to All Outputs
Troubleshooting - 1kHz Setup
Tone will not be sent to any Outputs
AES external clock is selected but no AES
input is connected to the unit
Note the flashing AES / SPDIF Ext word
clock led.
Use the internal sine wave generator to confirm output signals and to identify
left/right channels. A 100Hz, 1kHz or 10kHz internally generated sine wave at -40dB, -20dB or -
26dB to -6dB variable will be sent to all outputs.
When the input signal button is pressed the setup tone stops.
