702 User Guide and Technical Information
23
Outputs – Analog and Digital
The 702 has two independent output buses , the Analog Output Bus (Bus 1) and the Digital Output
Bus (Bus 2). Each side (left and right) of the two-channel buses are assigned audio sources indepen-
dently, allowing the 702 to feed multiple audio devices with unique program content.
The chart below shows the audio sources available for the analog and digital output buses. The au-
dio source for each output is selected in the Setup Menu.
Available Output Sources Description
Input
1
Input 2
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 input audio at the output.

Multiple track assignments are summed with these selections.
Analog Output Bus
Audio signals routed to the Analog Output Bus (Bus 1) are sent to three output connections:
• analog line out, TA3 x 2, two-channel
• analog tape out, 3.5 mm TRS, 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 output level can be attenuated from the
Setup Menu by up to 40 dB in 1 dB increments. Both left and right outputs are attenuated equally.
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 Output Bus
Just as with the Analog Output Bus, the Digital Output Bus (Bus 2) can be assigned signal sources
from inputs or tracks. Sources assigned to the Digital Output Bus are exclusive and do not affect the
assignments to the Analog Output Bus or headphone assignments. The same signal sources available
for the Analog Output Bus are available for Digital Output Bus (see chart above).
The Digital Output Bus appears solely on the AES3id BNC output connector. 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.
The maximum output level is 0 dBFS and can be attenuated in the Setup Menu in 1 dB increments by
40 dB.
