2.3 Connections
For connecting the DMA8Plus to your cinema processor, refer to Wiring Diagrams on
page 11. Use the appropriate diagram for your cinema processor model.
For proper operation in locations where there is considerable RF or other interference field,
strictly adhere to the cable types, lengths, and pin assignments. Shields must connect only
to the chassis and should not be paralleled with the negative side of inputs or outputs.
Pinout information for each connector is listed in Rear‐Panel Connector Descriptions and
Types on page 36.
2.4 Fuse Information
Warning: To reduce the risk of fire, replace fuses only with the same type and rating.
The DMA8Plus uses a universal‐switching power supply that handles the full range of
nominal mains voltages between 100 and 240 VAC, and any frequency between
50 and 60 Hz. If a power supply fuse blows, do not attempt to replace it. In such a case,
please contact Dolby Laboratories for a replacement power supply.
There are two fuses on the Cat. No. 758 board, which are user serviceable, as described in
Checking the Two User‐Serviceable Fuses on page 10.
