• After installation, check that the brake lamps, winkers, and wipers work properly. Controls Operations of the following control and switches are required in accordance with the center unit and speakers connected with this unit.

KAC-628 KAC-728/528 FILTER FILTER OFF OFF LPF HPF LPF • HPF (High Pass Filter) position (KAC-628 only) Only frequencies of 150 Hz or higher are output. (Frequencies below 150 Hz are cut.) • LPF (Low Pass Filter) position Only frequencies of 80 Hz or lower are output. (Frequencies above 80 Hz are cut.) The Lch and Rch will be mixed before output even if the operation switch is set to STEREO. • OFF position The original sound without filtering is output. 3 OPERATION switch This switch allows selection of the amplification method of input signals. • STEREO position The amplifier can be used as a stereo amplifier. • L+R position (KAC-628 only) The input left and right signals are combined before being amplified. Use this position when the unit is used for subwoofer speakers or the L+R (monaural) sound is required. • 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.) 4 INPUT 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. For the pre-output level or the maximum power output, refer to the “Specifications” NOTE MAXMIN 0.30.5 1.0 25 15 10 MONO(Lch)STEREO OPERATION KAC-728/528 MONO(Lch)STEREO L+R OPERATION KAC-628 5 LINE IN terminal 6 Speaker level input terminals 7 Fuse (20 A . 2 : KAC-728) (25 A . 1 : KAC-628) (15 A . 1 : KAC-528) 8 Battery terminal 9 Ground terminal 0 Power control (REMOTE) terminal ! SPEAKER OUTPUT terminals • Stereo Connections: When you wish to use the unit as a stereo amplifier, stereo connections are used. The speakers to be connected should have an impedance of 2. or greater. When multiple speakers are to be connected, ensure that the combined impedance is 2. or greater for each channel. • Bridged Connections: When you wish to use the unit as a high- output monaural amplifier, bridged connections are used. (Make connections to the LEFT channel (+) and the RIGHT channel (–) SPEAKER OUTPUT terminals.) The speakers to be connected should have an impedance of 4. or greater. When multiple speakers are to be connected, ensure that the combined impedance is 4. or greater. 2CAUTION The rated input of the speakers should be no less than the maximum output of the amplifier. Otherwise malfunction may result. (W) in the instruction manual of the center unit.
