AP20 Installation and Operating Guide Version 1.25
Appendix A. Connector Pin-outs A-6 Document #: 9301H39200 Ver. 1.25
The digital audio output pin-out is compatible with the XD10P Cinema Audio Processor as well as with
the Ultra Stereo JSD-80 cinema processor. The pin-out also matches the Dolby DMA8.
Datasat Digital Entertainment offers a DB25 male to female cable, 3-feet long, for hook-up (P/N
2503004100). If wiring your own cable, the following criteria must be met:
1. Cable must be double shielded to conform to FCC\CE RF radiation emission limits. Ground
shield on the AP20 end.
2. Conductors must be 28-AWG or larger.
3. Choose a paired AES/EBU Digital Audio Cable (such as Belden 7890A). To prevent signal
degradation, cable length should be kept as short as possible. If the cable is being run through
conduit, it is recommended that it be tested before installing, especially if approaching the
maximum length stated in the chosen cable’s spec.
