Resumen del manual
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. PLEASE NOTE! If using high level inputs, do not use the low level RCA inputs at the same time! wiring harness L L R R from speaker terminals head unit orange black black orange L/R audio outputs head unit Electrical Connections (all models) 5 2CH AMPS LA438 LA538 LA738 LA938 LA1438 LA1838 LA2038 to remote turn-on +12V head unit 12V battery Input Connections Low Level 4 CH Stereo Input from 2 CH Audio Source Low Level 4 CH Stereo Input from 4 CH Audio Source Left Output Right Output Input Connections Bridged Input Connection 4 CH Bridged Input from 2 CH Audio Source CH1+2 = Left Channel CH3+4 = Right Channel Left Output Right Output head unit Y adaptors to a second amplifier L + R Front Outputs L + R Rear Outputs 4CH AMPS LA638 LA838 LA1038 7 2CH AMPS LA438 LA538 LA738 LA938 LA1438 LA1838 LA2038 4CH AMPS LA638 LA838 LA1038 Y adaptors head unit Y adaptors head unit head unit speakSpeaeker rCosnnections Basic Stereo Output Basic 4CH Output FRONT speakers REAR speakers L R R L LEFT speaker RIGHT speaker inpInpuut Ctonnsections 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 wiring harness L R REAR FRONT L R orange black black orange orange black black orange head unit head unit L R L R REAR FRONT orange black black orange orange black black orange 4CH AMPS LA638 LA838 LA1038 9 2CH AMPS LA438 LA538 LA738 LA938 LA1438 LA1838 LA2038 4CH AMPS LA638 LA838 LA1038 High squeal noise from speakers. • This is almost always caused by a poorly-grounded RCA patch cord. Amplifier(s) gets very hot. • Check that the minimum speaker impedance for that model is correct. • Check for speaker shorts. • Check that there is good airflow around the amplifier. In some applications, an external cooling fan may be required. Distorted sound • Check that the Level control(s) is set to match the signal level of the head unit. • Check that all crossover frequencies are properly set. • Check for shorts on the speaker leads. Amplifier will not power up. • Check for good ground connection. • Check that remote DC terminal has at least +12v DC. • Check that there is battery power on the + terminal. • Check all fuses. • Check that Protection LED is not lit. If it is lit, shut off amplifier briefly and then repower it. High hiss or engine noise (alternator whine) in speakers. • Disconnect all RCA inputs to the amplif...
