INSTRUCTION MANUAL MODEL : BA150.1 BA75.2 BA150.2 BA75.4 BA500.1D BA800.1D BA1200.
Congratulations on your Purchase Your new high fidelity bridgeable/stereo amplifier is designed to deliver maximum enjoyment and one year of trouble free service. Please take a few moments to read this manual thoroughly. It will explain the features and operation of your unit and help insure trouble free installation. Features CLASS ''AB'' CLASS ''D'' Class ''AB'' Technology MOSFET PWM Power Supply. ¡ Bridgeable & TRI-Mode Operation.
Precautions: Read First! - Be sure to mount the amplifier to a strong, solid surface which will not give way under the stress of a sudden stop or accident. - Make sure that the mounting screws will not penetrate the gas tank, brake and fuel lines, wiring or other critical parts of your car when installed. - NEVER operate the amplifier without the proper power and ground wire 10 gauge minimum. - NEVER operate the amplifier without proper fusing. Fuse holder must be located with in 0.
Installation MOUNTING: 1. After reading precaution, decide where you are going to install the unit. Also, see Fig.1. 2. Once the location has been determined, place the amplifier in position. Using a felt tip pen or pencil mark the four holes to be drilled for mounting. NEVER use the amplifier as a template for drilling. It is very easy to damage the amplifier surface in manner. 3. Remove amplifier. Drill four 3.5 m/m. Diameter holes into mounting surface on steel panel.
Input Connections This amplifier will accept low level inputs. Low level is the same as line level or preempt level. Low level signal is carried through RCA cables. It is preferred to use low level inputs to the amplifier if the head unit is equipped with the low level outputs. Low level/line input-connect RCA cables from head unit, or other signal processor, to the line level input on the amplifier. See Fig.2 system wiring diagrams.

Speaker Connections This amplifier can operate in either one, two or three channel mode. The minimum impedance for single channel (bridged/mono) operation is 4-8 ohms. There channel tri-power is referred to stereo and mono at the same time. Minimum impedance remain the same for three channel (satellite/ subwoofer) systems as long as proper passive crossovers are used. Connect right and left speaker wire to corresponding speaker output terminals of the amplifier.

Adjustments 1. Set to the "H.P.F" position when the amplifier is used to drive a tweeter/midrange system. The frequencies below the crossover point will be attenuated at 12dB/octave. Permits adjustment of the crossover frequency ,by rotating the knob to select any frequency between 60Hz to 1.2KHz as the crossover point. 2. Set to the "L.P.F" position when the amplifier is used to drive a subwoofer. The frequencies above the crossover point will be attenuated at 12dB /octave.
Trouble Shooting The System We have put together this trouble-shooting guide if you experience problems after installing the amplifier. Please keep in mind that the majority of problems incurred are caused by improper installation and not the equipment itself. In addition, there are many components in the system that could cause various signal problems such as inducted electrical noise and engine noise.
