OWNER'S MANUAL HIGH PERFORMANCE AMPLIFIERS
B2 has through years of dedication introduced our line of Mono & Quattro amplifiers. The B2 line up are made to fullfil our philosophy for amplifiers; A variety of applications, highest possible efficiency and great appearance. The B2 amplifiers are designed to produce high power levels even from stock electrical systems. High efficiency is created from updating every stage through the amplifiers' circuit.
. CONTROL & CONNECTION 3-1. Mono CONTROL & CONNECTION INPUT Connect preamp signal cables from the headunit to RCA Input of Mono. OUTPUT Output RCA for signal routing to another amplifier. POWER & PROTECTION INDICATOR Power BLUE, Green-lit shows correct operation Protect LED, RED-lit shows general malfunction, faulty connection or thermal protection GAIN ( 6V ~ 0.2V ) Matching the output voltage of the headunit's RCA line-outs to Mono input section.
HIGH PASS FILTER ( 50Hz ~ 1KHz @ 12dB/Oct ) Adjusts the cut off point for the high pass filter. The wide frequency range allows for "Active" speaker operation. CROSSOVER SELECTOR Configuration of the filter mode. HPF/FULL/LPF. LOW PASS FILTER ( 30Hz ~ 300Hz @ 12dB/Oct ) Adjusts the cut off point for the low pass filter. REMOTE LEVEL CONTROL PORT Connection of external level control. 3-3. Mono & Quattro CONTROL & CONNECTION GND ( GROUND CONNECTION ) For connection to the chassis' ground.
For safety purposes, install the amplifier in a dry and well ventilated location and make sure no cables or other harness of the car is interfaced with the mounting location or will present a hazard to the cars' cable, control cables, fuel lines/tanks, hydraulic lines or other components of the vechicle. 4-3.
4-4. SPEAKER CONNECTION B2 amplifier series recommends 12 AWG speaker connecting cables. Run 12 AWG speaker connecting cables from your speakers to amplifiers' mounting location Keep speaker cables away from power cables and B2 series amplifier's input cables. Use grommets anywhere the cables have to pass through the holes in the metal frame or sheet metal. Connect to the speakers according to terminals on each speaker.

4-5. Mono DAISY CHAIN CONNECTION Daisy chain connection allows linking of 2 mono amplifiers to work as 1. Please read the following connection diagram cautiously to ensure the correct connection. Step 1. Connect the master Mono amplifier to the head-unit and set its output master and input slave switch to the output master position. Step 2. Connect the master and slave Mono amplifier in daisy chain Rca jack as shown in the diagram. Step 3.
Headunit FUSE 360A GROUND 12V 8 ohm ~ 2ohms Main Battery CAUTION Mono Minimum daisy chain connection impedance is 2 ohm Do not use daisy chain connection in 1 ohm Mono working Voltage is 9V ~ 16V.
5. TROUBLE SHOOTING TIPS NO SOUND ( NO OUTPUT ) 1) Pls check all connections, cables' rounting, short, voltage at Mono & Quattro amplifiers and headunit 2) Pls check fuses ,If they are blown, pls replace with new ones. 3) Pls check whether speakers are functional. You can connect a AA battery to the speaker terminals to see if there is any movement of the speaker cone. PROTECTION 1) Pls check overload, overheat ( thermal ), short and voltage.
