User manual BLITZ BZT19 INSTALL GUIDE

[. . . ] This knob is not a volume control signal levels. 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. Always use high quality shielded RCA cables. 8. LINE OUT RCA JACKS The LINE OUT allows you to build multiple amplifier systems without having to use splitter cords to distribute the signal. [. . . ] 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. 9. BRIDGED MODE 4 Features & Controls Features & Controls 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". Note: IF YOUR RADIO DOES NOT HAVE +12 VOLT OUTPUT LEAD WHEN TURNED ON, THE "REMOTE" TERMINAL ON THE AMPLIFIER CAN BE CONNECTED TO VEHICLES ACCESSORY CIRCUIT WHICH PROVIDES +12V WHEN THE CAR IS ON. 12. B+ TERMINAL (BATTERY POSITIVE) Due to the power requirements of the Amplifier, this connection should be made directly to the positive(+) terminal of battery. For safety measure, install an in-line fuse Holder (not included) as close to the battery positive(+) terminal as possible with an ampere rating not to exceed total value of fuses in Amp. 13. REMOTE CONTROL INPUT LEVEL MIN MAX MIN REMOTE LEV EL MA X Remote Bass Boost Control Remote Bass Boost Control : This control adjusts the Bass Boost gain for the amplifier's speaker output (0 - +18dB) 5 Installation & Precautions Installation 1. Find a suitable location in the vehicle to mount the amplifier. Make sure there is sufficient air flow around the intended mounting location. Bolt the amplifier to the mounting surface. Connect the power ground terminal to the nearest point on the chassis of the car. Keep this ground wire less than one meter (39") in length. Connect the remote terminal to the remote output of the head unit using 14 gauge wire. 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. 6 System Wiring Wiring Diagram BZA-1000D / BZA-2000D BRIDGED MODE SLAVE MASTER LINE INPUT LINE OUT L DATA LINK PWR.

Check that remote DC terminal has at least 3V DC. Check that there is battery power on the + terminal. 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. [. . . ] It is best to set the amplifier's input level as low as possible. The best subjective S/N ratio is obtainable this way. 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. Check that the volume control on the head unit is turned down low. [. . . ]
