Front Panel Descriptions

1) Mode Switch

The Mode Switch is a non-locking toggle
switch which controls the conversion modes
of the ADC1 USB.
Mode Switch Operation
The ADC1 USB can be programmed to
function in a variety of conversion modes,
including simultaneous multiple sample rates,
bit depths, and output formats using internal
and/or external clock sources.
The USB output sample rate is always
controlled by the computer with which it is
operating. This is typically set in the
recording software (DAW), but it is
sometimes set within the audio-utility control
panel of the operating systems (e.g.
'AudioMIDI Setup' in Mac OS X).
The conversion modes of the other four
outputs (XLR, optical, main coax, and
auxiliary coax) are set with the Mode Switch
by using press-and-release or press-and-hold
actions. These functions are described in the
"Conversion Mode Programming" section.

Conversion Mode Programming
Press-and-release the Mode Switch up
•
to cycle through the clock source and
sample rate options for the Main
Outputs.
Press-and-release the Mode Switch
•
down to cycle through the sample rate
and bit depth options for the Aux
Output.
Press-and-hold the Mode Switch down
•
for approximately 3 seconds to switch
the optical output mode between
AES/EBU and ADAT.
Press-and-hold the Mode Switch up for
•
approximately 3 seconds to reset the
ADC1 USB to Factory Default settings.
Factory Default Settings
The ADC1 USB can be easily reset to factory
default settings by pressing and holding the
Mode Switch up for approximately 3 seconds.
The factory default setting syncs the main
and aux outputs to the external clock and
configures the optical output in AES/EBU
format.
