Terminal cover .... .... ¦ RCA cable or Speaker level input connection ¦ Power wire and Speaker wire connection ¦ Remote cable connection (KAC-7252 only) Remote cable Remote controller Genuine-accessory car stereo (No line output center unit etc.) ACC Battery Car fuse box • RCA cable Connections • Speaker level input Connections Cable Color of the connector Left 9 White · White/Black Right 9 Gray · Gray/Black Power control wire 2CAUTION • Before connecting the remote controller cables, always set the Bass boost level control to "0dB". English 5 Controls NOTE The control panel locates under the front side cover. Remove the cover to access to its controls for adjustment. (See page 3) 1 Fuse (40 A .1) NOTE If you can’t find the specified capacity fuse at your store etc., consult your Kenwood dealer. 2 Battery terminal 3 Ground terminal 4 Power control terminal Controls the unit ON/OFF. NOTE Controls the unit power. Be sure to connect it with all the systems. 5 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 9 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. 6 REMOTE terminal (KAC-7252 only) Connects the Remote cable. NOTE Use the Remote cable of the accessory. 7 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. 8 RCA cable ground lead terminal When using an RCA cable with a ground lead attached, connect the ground lead to this terminal. 9 LINE IN terminal 0 LINE OUT terminal The signal that’s input from the line input terminal is output. ! 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. (See page 2) @ BASS BOOST LEVEL control (KAC-7202 only) Sets the low frequency level to be compensated. # LPF FREQUENCY control Sets the cutoff frequency when the "FILTER" switch is set to "LPF". $ HPF FREQUENCY control Sets the cutoff frequency when the "FILTER" switch is set to "HPF". % FILTER switch This switch allows to apply high-pass or low-pass filtering to the speaker outputs. • HPF (High-Pass Filter) position: The filter outputs the band of higher frequencies than the frequency set with the "HPF FREQUENCY" control. • OFF position: The entire bandwidth is output without filtering. • LPF (Low-Pass Filter) position: The filter outputs the band of lower frequencies than the frequency set with the "LPF FREQUENCY" control. The speaker output is automatically switched to monaural (L+R). ^ 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 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 genuineaccessory 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
