Available Output Sources Description
Input

Input 2
Input

Input 4
Inputs are assignable for each channel of the output bus.
When inputs are selected as the source for the outputs, the state of recording or playback activity has no
effect on the output signal. This allow uninterrupted audio at the outputs.

Master Output Bus
Audio signals routed to the Master Output Bus are sent to three output connections:
• analog line out, 2 x TA3, two-channel
• analog tape out, 3.5 mm TRS, two-channel
• digital 1, AES3id, BNC connection, two-channel
Analog Line Out L, R
The analog line outputs are active-balanced line-level signals on Switchcraft TA3M locking connec-
tors. The output level is a nominally 0 dBu at
-
20 dBFS. The level of the line output can be attenuated
in the setup menu by up to 40 dB in 1 dB increments. Attenuation is done as an output pair.
Analog Tape Output
The tape output connection is stereo, unbalanced consumer output level (–10 dBV) on a TRS 3.5 mm
connector. Output attenuation affects this output level.
Digital AES3id Output
The unbalanced AES3id output is directly compatible with most S/PDIF inputs.
The format for the AES3id output is selectable between professional AES and SPDIF. In either case
the SCMS bit is not set.
Attenuation to the Master Output Bus affects both analog and digital signals.
Output Bus 2
Just as with the Master Output Bus, Output Bus 2 can be assigned signal sources from inputs or
tracks. Sources assigned to Output Bus 2 are exclusive and do not affect the assignments to the Mas-
ter Output Bus or headphone assignments. The same signal sources available for the Master Output
Bus are available for Output Bus 2 (see chart above).
