2.6 Connections
Refer to the connection diagrams in Section 2.7 for installation wiring to your cinema
processor. The diagrams are located at the end of this chapter. Use the appropriate
page for your cinema processor model. Pinout information on each connector is listed
in Section 5.4
To provide proper operation in locations where there is a large RF or other
interference field, ensure that the cable types, lengths, and pin assignments are strictly
adhered to. Shields must connect only to the chassis and should not be paralleled with
the “–” side of inputs or outputs.

2.6.1 Digital Media Automation Connector
The DMA8 provides a ground-switching interface for connecting to a theatre
automation system. The automation system can switch between film sound (pass-
through) and a digital media source. The connector can be wired to automation
systems to switch the DMA8 in and out of Digital Media mode. This function is a
duplication of the front-panel Digital Media and Film buttons.
