B.3.2 Analogue Audio
The TT1260 supports level control of the audio outputs. Independent
control of each output of each stereo pair is provided via the User
Interface and remote interfaces.
Audio output connector type: 2 X 9 way female D-type
Output level: +18 dBm nominal clipping level. Selectable in range 12 to
+24 dBm.
Output impedance: 50 W (nominal).

B.3.4 Embedded Audio
Either or both of the stereo pairs selected for decoding by the Receiver can
be routed out via the SDI video output, as AES/EBU digital audio
embedded in the Ancillary Data Space, as defined in SMPTE 272M-1994.
The operational level of this standard supported is SMPTE 272M –A
(20-bit synchronous audio at sampling rates of 48kHz).
B.3.5 Audio Routing
The IRD supports the following routing of the stereo audio signal under
control of the User Interface and remote interfaces:
·
Normal stereo (left signal to left output, right signal to right output)
·
Left to both (left signal to left and right outputs)
