15. SR-1000 INPUT AND OUTPUT
15.4 Audio Output from the SR-1000
The SR-1000 features 16-channel AES3 digital audio signal via 2x RJ45 Outputs (A-top and A-
bot) or 24-channel AES3 digital audio signal via 2x RJ45 Outputs (A-top and A-bot) and an
additional RJ45 Output (Audio AES 17-24) depending on the SR-1000 configuration chosen.
Channels 1 to 8 are available on the A-top connector and carry the processed 6- or 8-channel
main audio tracks for 5.1 and 7.1 DCPs respectively, assuming that DCPs follow the 16-channels
ISDCF recommended channel order. Channels 9 to 16 are used for Hi/Vi-N, Booth Monitor, LTC
(4D systems), D-Box Motion Data signal, etc. (refer to ‘SR-1000 User Manual’ for more details).
For DTS-X™/ IAB playback; Channels 9 to 16 carry the processed audio for the additional
surround channels with the SR-1000 Extreme configuration. With the SR-1000 Extreme -24
configuration, Channels 17 to 24 are available on the Audio AES 17-24 connector and carry the
additional surround channels for upto 24-channels of DTS-X™/IAB playback.
Note: Since the SR-1000 Extreme -24 provides up to 16-channels of audio processing; when
utilizing more than 16-channels, an external audio processor capable of processing 24-channels
needs to be used.
Additionally, if audio processing feature is not available on the SR-1000 or it is disabled; the
Channels 1 to 8 and Channels 9 to 16 will carry unprocessed audio and an external audio
processor capable of processing 16-channels needs to be used.
