3.3. ELECTRICAL CONNECTIONS
Before wiring the projector, refer to Figure 3-3 for the wiring interface diagram. Use
stranded wire. Strip and tin the wire prior to connection. Use crimp connectors on all sound
connections. For projectors equipped with an automatic turret, refer to Section 6.6.3.
3.3.1. SOLAR C ELL WIRING
Solar cell wiring requires a shielded, four-conductor audio cable. (red – left (+), black – left
(-), green – right (+), white – right (-)). The best signal-to-noise ratio is achieved by
maintaining the same ground potential between the sound-head and the cinema processor.
Refer to the directions in the sound system instruction manual for proper connection of the
sound system.
