Resumen del manual
• Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals. • If you need to replace the power fuse, only replace it with a fuse identical to that supplied with the system. Using a fuse of a different type or rating may result in damage to your system which isn’t covered by the manufacturer’s warranty. Setting Up and Turning On Your New Amplifier After all electrical connections have been made, and physical installation is complete, turn on your stereo and listen for the amplifier to turn on. If there are any unusual noises from the speakers, turn the stereo off and recheck ALL wiring. Assuming the amplifier turn on normally, you may have to adjust the LEVEL control(s) to match the output levels from your head unit. Follow these steps: 1. Set the volume control on your head unit to about the 2/3 position. 2. Adjust the amplifier LEVEL control(s) to an average listening position. 3. Turn the head unit volume all the way down, and listen for background noise. 4. Start your vehicle, and again, listen for background noise. 5. By fine tuning the LEVEL control(s), you can reduce background and engine noise, if present. These adjustments should only be made once. After that, use the head unit volume control to adjust the system volume, not the LEVEL control(s). CAUTION: Never turn the LEVEL control(s) up any higher than you need to get clear sound at 2/3 volume on the head unit. 5 PLEASE NOTE! If using high level inputs, do not use the low level RCA inputs at the same time! wiring harness R R L L from speaker terminals head unit orange black black orange L/R audio outputs head unit Electrical Connections (all models) to remote turn-on +12V head unit 12V battery 7 Input Connections inpInpuut Contnecstions LA670 LA870 4CH AMPS Low Level 4 CH Stereo Input from 2 CH Audio Source Low Level 4 CH Stereo Input from 4 CH Audio Source LA670 LA870 4CH AMPS High Level 4 CH Stereo Input from 4CH Audio Source floating ground connection High Level 4 CH Stereo Input from 4CH Audio Source common ground connection Left Output Right Output L + R Front Outputs L + R Rear Outputs head unit wiring harness R L REAR FRONT R L orange black black orange orange black black orange head unit head unit R L R L REAR FRONT orange black black orange orange black black orange head unit Y adaptors Input Connections speaSkpeakeer Conrnecstions Bridged Input Connection 4 CH Bridged Input from 2 CH Audio Source CH1+2 = Left Channel CH3+4 = Right Channel Basic Stereo Output Basic 4CH Output 9 head unit Y adaptors to a second amplifier Left Output Right Output FRONT speakers REAR speakers L R R L LEFT speaker RIGHT speaker 2CH AMPS LA670 LA870 4CH AMPS LA370 LA470 LA570 LA770 LA970 LA1470 LA1870 LA2070 LA670 LA870 4CH AMPS 2CH AMPS LA370 LA470 LA570 LA770 LA970 LA1470 LA1870 LA2070 head unit Y adaptors Speaker Connections troubleshootTriounbles...
