The digital audio output pin-out 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 RS20i 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.

Note: RS20i Analog channels are designed to be balanced, not single ended, for highest sound
quality. If wiring single ended, wire only to (+) and ground. The (-) side of the channels should
not be connected. Do not short the (-) sides of the channels to ground, which will degrade sound
quality and cause the RS20i to overheat.
