4 English Controls / Indicator (W) 30 40 20 10 25 1 FILTER switch This switch allow filtering of the speaker output signals. • OFF position: The original sound without filtering is output. • LPF (Low Pass Filter) position: Only frequencies of 80 Hz or lower are output. (Frequencies above 80 Hz are cut.) The speaker output is automatically switched to monaural (L+R). 2 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. NOTE For the pre-output level or the maximum power output, refer to the in the instruction manual of the center unit. 3 LINE IN terminal 4 Speaker level input terminals NOTE • The genuine-accessory car stereo shall have a maximum power output of no more than 40 W. • Do not connect the speaker output leads from a power amplifier (Optional) to the speaker level input terminals of this unit, for this may cause malfunction or damage. • Do not connect cables and leads to both RCA cable input jacks and the speaker level input terminals simultaneously, for this may cause malfunction or damage. • Connect the power control lead to a power supply which can be turned ON/OFF by the ignition key switch (ACC line). With this connection, shock noise may be generated when the power of the genuine-accessory car stereo is switched ON/OFF. 5 Fuse (25 A) 6 Battery terminal 7 Ground terminal 8 Power control terminal Controls the unit ON/OFF. NOTE Controls the unit power. Be sure to connect it with all the systems. 9 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 2Ω or greater. When multiple speakers are to be connected, ensure that the combined impedance is 2Ω 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 9 and the RIGHT channel · SPEAKER OUTPUT terminals.) The speakers to be connected should have an impedance of 4Ω or greater. When multiple speakers are to be connected, ensure that the combined impedance is 4Ω or greater. 2CAUTION The rated input of the speakers should be no less than the maximum output of the amplifier. Otherwise malfunction may result. B64-3533-00_00_KAC-5203_M.indb 4 B64-3533-00_00_KAC-5203_M.indb 4 06.11.9 8:48:43 PM 06.11.9 8:48:43 PM
