744T User Guide and Technical Information
Outputs – Analog and Digital
The 744T has two discrete output buses, the Master Output Bus and Output Bus 2. Each of these
The chart below shows the audio sources available for the Master Output Bus and for Output Bus 2. The audio sources for each output bus are selected in the setup menu.

Master Output Bus
Audio signals routed to the Master Output Bus are sent to three output connections:
•analog line out, 2 x TA3,
•analog tape out, 3.5 mm TRS,
•digital 1, AES3id, BNC connection,
Analog Line Out L, R
The analog line outputs are
Analog Tape Output
The tape output connection is stereo, unbalanced consumer output level
Digital AES3id Output
The unbalanced AES3id output is directly compatible with most S/PDIF inputs. 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 Master Output Bus or headphone assignments. The same signal sources available for the Master Output Bus are available for Output Bus 2 (see chart above).
Digital AES3id Output 2
Output Bus 2 appears solely on the AES3id BNC output connector. There is no analog output connections for Output Bus 2. The unbalanced AES3id output is directly compatible with most S/PDIF inputs. The maximum output level is 0 dBFS and can be attenuated in the setup menu in 1 dB increments by 40 dB.
