The stereo amplifier on one side is called amplifier A, while the one on the other side is amplifier B. The monaural amplifier is called the amplifier SUB. This unit is compatible with a large variety of systems by combining the switches and functions described in the following. 1Fuse (25 A . 2) 2Power control terminal 3Battery terminal 4Ground terminal 5Amplifier A/B speaker output terminals • Stereo Connections: When you wish to use the unit as a stereo amplifier, stereo connections are used. • Bridged Connections: When you wish to use the unit as a highoutput monaural amplifier, bridged connections are used. (Make connections to the LEFT channel (+) and the RIGHT channel (-) SPEAKER OUTPUT terminals.) 6Amplifier SUB speaker output terminal As this unit accepts speakers with a minimum impedance of 2 ohms, connect speakers with 2-ohm or higher impedance to these terminals. 7Speaker level input terminals A center unit with no RCA output can still be connected to the speaker output. Again, even without a power control signal, the power is switched ON/OFF automatically by the speaker signal. 8HPF(High-Pass Filter) switch When this switch is set to 80 Hz or 150 Hz, frequencies below the setting value will be cut. 9INPUT SELECTOR (A/AB) switch This switch toggles the input signal of amplifier B. • A position: The input for terminal A is output from amplifiers A and B. • AB position: The input for terminal A is output from amplifier A, while the input for terminal B is output from amplifier B. 0INPUT SENSITIVITY control Set this control according to the pre-output level of the center unit connected with this unit, or to the maximum power output of the genuine-accessory car stereo. Use the diagram on the right as a guide. The sensitivities of amplifiers A, B and SUB can be adjusted independently regardless of the position of the input selector switch. For the pre-output level or the maximum power output, refer to the “Specifications” in the instruction manual of the center unit. !RCA cable ground lead terminal When using an RCA cable with a ground lead attached, connect the ground lead to this terminal. Do not use this terminal for power source grounding. This unit will be damaged if the power source grounding wire is connected to this terminal. @Amplifier A/B/SUB LINE IN terminal #SUB.CH LPF(Low-Pass Filter) FREQUENCY control This control adjusts the frequency band output from this SUB channel. $OPERATION switch This switch is used to select the operation mode of the amplifier. • STEREO position: The amplifier can be used as a stereo amplifier. • MONO (Lch) position: Amplifies the signal input from the left side only. Set to this position and make bridged connections to use as a high-power monaural amplifier. (The input right signal is not output.) %INPUT SELECTOR (AB/SUB) switch This switch toggles the input signal of amplifier SUB. • AB position: The input for terminals A and B input is mixed and output from amplifier SUB. The input signal varies according to the setting of the INPUT SELECTOR (A/AB) switch and the OPERATION switch. • SUB position: The input for the SUB terminal is output by amplifier SUB. Power indicator When the power is turned on, the Power indicator lights. If the Power indicator does not light when the power is turned on, the protection function may be activated. Check whether there is any indication of trouble. ¦ The protection function is activated in the following situations: This unit is equipped with a protection function for protecting this unit and your speakers from various accidents or problems that can occur. When the protection function is triggered, the Power indicator goes off and the...
