Resumen del manual


DO NOT enclose the amplifier in a small box or cover it so that air is not able to flow freely. Temperatures in car trunks have been measured as high as (155 F) in the summer time. As the thermal shut down point for the amplifier is (185 F), it is easy to see that it must be mounted in an area that provides for maximum cooling capability. To achieve maximum advantage of convection air flow in an enclosed trunk, mount the amplifier in a horizontal position. Cooling requirements are considerably relaxed when the mounting inside the passenger compartment since the driver compartment will not allow temperatures to reach a critical point. Floor mounting under the seat is usually satisfactory as long as there is at least 1 inch of clearance above the amplifier’s heat sink for ventilation. A. Select a suitable location that is convenient for mounting, is accessible for wiring, and has ample room for air circulation and cooling. B. Use the amplifier as a template to mark the mounting holes. Remove the amplifier and drill holes. Use extreme caution, inspect underneath surface before drilling! C. Secure the amplifier using the screws provided. Caution: Before connecting any wires to the amplifier, disconnect the ground lead from the battery. Leave the ground lead disconnected until you are done wiring the amplifier. 10 P L A N N I N G & M O U N T I N G Y O U R S Y S T E M PMA600HCE / PMA1000HCE 11 W I R I N G D I A G R A M S MONO MODE STEREO MODE TRI MODE BRIDGED PMA640HCE 2 CHANNEL MODE 3 CHANNEL MODE 4 CHANNEL MODE 12 W I R I N G D I A G R A M S PMA640HCE 13 W I R I N G D I A G R A M S 6 CHANNEL MODE Turning On The Amplifier The amplifier automatically turns on a few seconds after you turn vehicle’s ignition switch to ACC ON or turn on your auto sound system, depending upon how you wired the system. The POWER indicator on the top of the amplifier illuminates when the amplifier is on. Important: Your amplifier requires 90 amps or more of power from your vehicle’s battery during operation. To protect your battery from your battery from discharging, do not operate the amplifier unless your vehicle us running. Adjusting The Audio Level (“Gain Matching”) By Ear For best performance, you must match the amplifier’s input sensitivity to your source unit’s maximum output level. The GAIN CONTROL (MIN / MAX) located on the side of the amplifier is designed to do this. It is Not a volume control. It adjusts the incoming signal level so that the source unit and amplifier reach maximum output at the same time. This assures that maximum system is achieved with minimal distortion. 1. Turn the GAIN CONTROL (MIN / MAX) fully counterclockwise to MIN. 2. Play full frequency music that has continuous high levels (FM pop music is a good choice). 3. Turn up the source unit’s volume control until just before you hear the source unit’s distortion or 90% of full output (which ever comes first). 4. SLOWLY turn the GAIN CONTROL clockwise until just before you hear amplifier or speaker distortion, until you reach a maximum comfortable listening level (which ever come first). 5. Turn the source unit’s volume control back to a desire comfortable listening level and enjoy. RESPONSE ( dB) FREQUENCY RESPONSE BASS BOOST ON + 20dB + 10dB 0dB -10dB -20dB -30dB 10 50 100 500 1K 5K 20K 50K 14 A D J U S T I N G & T U N I N G Note: Raising the LPF frequency allows higher frequencies to reach the bass speakers while blocking lower frequencies from midrange speakers. Lowering the LPF frequency allows lower frequencies to reach the midrange speakers while blocking higher frequencies from bass. 15TROUBLESHOOTING15TROUBLESHOOTING SYMPTOMS CHECK REMEDY NO SOUND Is the power LED illuminator? (NO) Check all fuses to amplifier. Be sure Turn-on lead is connected. Check signal leads. Check gain control. Check tuner/deck volume level. Clean contacts on fuse holders Is the Diagnostic LED illuminated? (YES) Check for speakers short or amplifier overheating AMP. NOT SWITCHING ON No power to power wire Repair power wire or connections No power to remote wire with receiver on Check connections to radio Burnt or broken fuse Replace fuse NO SOUND IN ONE CHANNEL Check Speakers Leads Inspect for short circuit or an open connection Check Audio Leads Reverse Left Right RCA inputs to determine if the problem is occurring before the amp. AMP. TURNING OFF MEDIUM / HIGH VOLUME Check Speaker Load Impedance Be sure proper speaker load impedance recommendations are observed. (If you use an ohmmeter that DC resistance and AC impedance may not be the same). PROTECTION LAMP ON Shut down Turn radio down, wait for amp. To cool Speaker wires shorted Separate speaker wires and insulate Investigate the layout of your vehicle thoroughly before drilling or cutting. Take care when you work near the gas tank, gas lines, hydraulic lines, electrical components and electrical wiring. Do not use the equipment unmounted. Attach this system securely to prevent damage, particularly in the event of an ac...
