User manual BLITZ BZAKT04 INSTALL GUIDE

[. . . ] Use with full-range speakers, or with external crossovers. 5. VARIABLE HIGH-PASS FILTER(40Hz ~ 3kHz) When Crossover Mode Selector is in High Pass Mode, this control limits the frequencies which will be distributed to the speakers to those above the value to this is set within the range 40Hz~3kHz. 6. INPUT LEVEL(INPUT SENSITIVITY ADJUSTMENT) This control adjust the amplifier's input sensitivity. A lower signal level will require increased sensitivity for full power. A higher signal level will require decreased sensitivity. 7. LINE INPUT RCA JACKS These inputs are for signal cables from the source. [. . . ] Now it is simple a matter of bringing one set of RCAs into the first amplifier, then using the line out RCA jacks as the feed to the next amplifier. 5 Features & Controls Features & Controls 9. LED Indicator - POWER : This GREEN LED will illuminate when the amplifier is turned "ON". If it fails to illuminate, check the power connections to the Amplifier and fuses. - PROTECTION : The amplifier protection circuitry will disable the amplifier if input overload, short circuit or extremely high temperature conditions are detected. When the protection mode is in operation, the LED indicator on the side panel will be illuminated, indicating the amplifier has gone into a self preservation mode. If you observe that the Protection LED is lit, please check the system carefully to determine what has caused the protection circuit to engage. The amplifier can be reset by turning the remote power off and then on again. If the amplifier shut down due to a thermal overload condition, please allow it to cool down before restarting. If the amplifier shut down because of an input overload or short circuit, be sure to repair these conditions before attempting to power up the amplifier again. 10. B- TERMINAL (CHASSIS GROUND) To avoid unwanted ignition noise caused by ground loops, it is essential that the Amplifier be grounded to a clean, bare, metal surface of the vehicles chassis. 11. REMOTE POWER ON To remote wire car stereo. This amplifier is turned "ON" remotely when vehicle's stereo is turned "ON". Do not mount this amplifier so that the wire connections are unprotected or in a pinched condition, or likely to be damaged by nearby objects. Be sure to select a location inside your vehicle which has adequate ventilation. . 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 fo a different type or rating may result in damage to your system which isn't covered by the manufacturer's warranty. 8 System Wiring System Wiring BZA-2290 / BZA-2390 / BZA-2490 MONO MODE L SPEAKER BRIDGED MODE R SUB WOOFER 4~8 OHM STEREO MODE L LIFT SPEAKER 2~8 OHM SPEAKER BRIDGED MODE R RIGHT SPEAKER 2~8 OHM TRI MODE BRIDGED 4~8 OHM SPEAKER L LIFT SPEAKER 4~8 OHM BRIDGED MODE R RIGHT SPEAKER 4~8 OHM INDUCTOR LOW PASS FILTER CAPACITOR HIGH PASS FILTER 9 System Wiring System Wiring BZA-4190 2CHANNEL MODE BRIDGED BRIDGED BRIDGED 4~8 OHM CH1 CH2 CH3 CH4 BRIDGED 4~8 OHM 3CHANNEL MODE BRIDGED BRIDGED CH1 CH1 SPEAKER 2~8 OHM CH2 CH3 CH4 BRIDGED 4~8 OHM CH2 SPEAKER 2~8 OHM 4CHANNEL MODE BRIDGED BRIDGED CH1 CH1 SPEAKER 2~8 OHM CH2 CH3 CH4 CH4 SPEAKER 2~8 OHM CH2 SPEAKER 2~8 OHM CH3 SPEAKER 2~8 OHM 10 System Wiring System Wiring BZA-4190 6CHANNEL MODE SUB WOOFER 4~8 OHM SUB WOOFER 4~8 OHM BRIDGED BRIDGED CH1 CH1 SPEAKER 4~8 OHM CH2 CH3 CH4 CH4 SPEAKER 4~8 OHM CH2 SPEAKER 4~8 OHM CH3 SPEAKER 4~8 OHM INDUCTOR LOW PASS FILTER CAPACITOR HIGH PASS FILTER 11 Troubleshooting Troubleshooting Amplifier will not power up. Check for good ground connection. 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 amplifier(s)-if hiss/noise disappears, then plug in the component driving the amplifier and unplug it's inputs. If hiss/ noise disappears, go on until the faulty/noisy component is found. It is best to set the amplifier's input level as low as possible. [. . . ] Try to drive as high a signal level from the head unit as possible. Protection LED comes on when the amplifier is powered up. Check for shorts on speaker leads. If the Protection LED still comes on, then the amplifier is faulty. Amplifier(s) gets very hot. Check that the minimum speaker impedance for that model is correct. In some applications, an external cooling fan many be required. Distorted Sound Check that the Level control(s) is set to match the signal level of the head unit. [. . . ]
