INSTALLATION 0 1. PLAN THE INSTALLATION Before you go any further with the installation of the amplifier, map out the system and the necessary wiring. Your work will be simplified if you have a plan of attack. Consider all electrical requirements, as well as physical, such as amplifier ventilation and availability of space. 2. SELECT OPERATING MODES (on underside) The configuration switches are accessible by removing the plugs on the underside of the amplifier.
~ 5. WIRING The only tool needed to make wire terminations at the amplifier will be a flat blade-type screwdriver and either wire strippers or a knife. When baring wires for connection to the amplifier, remove approximately 98” of the insulation, insert into the terminal block, and tighten the screw. Determine from the chart below the minimum gauge power and ground wire for your application. up to 5’ Soundstream Power40 or Power80 (4 or 8 ga.) up to 10’ Soundstream Power40 or Power80 (4 or 8 ga.
8. PROTECTION CIRCUITS 10. SERVICE Your REFERENCE405 amplifier is protected against both overheating and short circuits by means of the following circuits: 0 Main power supply fuses (2 at 20 amps each) 0 Smart Power Supply Thermal Rollback activating at 85OC. 0 A fail-safe thermal protection circuit activating at 95OC. 0 Speaker over-current protection relays (on the 4 x 25 watt channels). Your amplifier also incorporates an innovative Fault Diagnosis system that identifies a blown power supply fuse.
