INTRODUCTION HERTIAGE amplifiers provide high-performance sound reinforcement for your mobile audio equipment. Its versatility enables compatibility with optional Equalizers, Frequency Dividing Crossover Networks, and other audio processors in a customized system. The Multi-Mode bridging capabilities allow flexibility in hosting several different speaker configurations. To achieve optimum performance, it is highly recommended that you read this Owners Manual before beginning installation.

CONNECTING THE POWER CAUTION: AS A PRECAUTION, DISCONNECT THE POWER WIRE FROM THE BATTERY WHILE MAKING THE POWER AND GROUND CONNECTIONS TO THE AMPLIFIER. 4/8 GAUGE(Thicker if planning for additional Amplifiers) wire is recommended for both the power and ground wires 12 Gauge, for the remote turn-on wire 16 Gauge. Both types are available at most Mobile Audio Dealers or Installation Shop.

CONTROL FUNCTIONS 1. RCA input jacks These RCA input jacks are for use with source units that have RCA or Line level outputs. A source unit with a minimum level of 200mV is required for proper operation. The use of high quality twisted pair cables is recommended to decrease the possibility of radiated noise entering the system. 2. GAIN Control The level control will match the amplifiers sensitivity to the source units signal voltage. The Operating range is 200mV minimum to 6V maximum.
CONTROL FUNCTIONS 8. LED Will illuminate GREEN to indicate the amplifier is on and operating normally, and will be illuminated RED if the amplifier shuts down due to short circuit, DC offset, or overheating detected by on board protection circuitry 9. Auxiliary outputs The Auxiliary outputs offer HERTIAGE amplifiers easy, unlimited system expansion. Route RCA’s from the line out of the first amplifier to the line input of a second amplifier when using a single source output. 10.

TROUBLE SHOOTING GUIDE SYMPTOMS NO SOUND AMP NOT SWITCHING ON NO SOUND IN ONE CHANNEL AMP TURNING OFF MEDIUM/ HIGH VOLUME CHECK POINTS CURE Is the power LED illuminated? Check fuses in amplifier. Be sure Turn-on lead is connected No power to power wire Repair power wire or connections No power to remote wire with receiver on Check connections to radio Fuse broken Check fuse Check speaker leads Inspect for short circuit or an open connection.
WARNINGS Investigate the layout of your automobile thoroughly before drilling or cutting any holes. Take care when to work near the gas tanks, lines, or hydraulic lines, and electrical wiring. Don't use power amplifier unmounted. Attach this system securely to the automobile to prevent damage, particularly in the event of an accident. Don't mount this system so that the wire connections are unprotected or are subject to pinching or damage from nearby objects.
