A NOTE ON WIRING

A note on wiring:
There are four types of wiring systems associated with all Synthesis systems:
• Signal wiring: RCA-to-RCA type interconnects will serve to route analog audio signals between the surround processor,
the SDEC and the power amplifiers. Only high-performance interconnects should be used. A pre-fabricated set of cables
is provided with the SDEC. Any additional interconnects added to the system should be of equal or greater quality to
ensure trouble-free operation.
• Speaker wiring: Only high-performance, heavy gage speaker wire should be used. Any wire-runs through or within
walls must conform to local flammability requirements and be appropriately marked; CL-3 is one example of such
a rating. Refer to the Synthesis S-400/S-650 Power Amplifier User’s Manual for more information about selecting
appropriate speaker wires.
• AC power: It is recommended that the system be connected to a dedicated 20-amp AC circuit. If this is not an option,
try to avoid using an AC circuit that is shared with heavy appliances. Never connect any Synthesis equipment into a
switched outlet. Removing the AC power while the system is ON will cause no permanent damage, but may lock up its
microprocessors, necessitating turning the system fully off, then on again. It may also cause loud pops and clicks in
the loudspeakers.
• Control lines: All Synthesis components communicate with one another via a standard DIN connection cable. This
cable enables automatic power an mode switching of the entire system from the surround processor.
