• Do not install near the dashboard, rear tray, or air bag safety parts. • The installation to the vehicle should securely fasten the unit to a place in which it will not obstruct driving. If the unit comes off due to a shock and hits a person or safety part, it may cause injury or an accident. • After installing the unit, check to make sure that electrical equipment such as the brake lamps, turn signal lamps and windshield wipers operate normally.

P.CON OUTPUT RIGHT A B POWER AMPLIFIER GND 2 34 L A A R L R B A B B This is a 4 channel amplifier including 2 stereo amplifiers in a body. One amplifier is referred to as amplifier A and the other is amplifier B. This unit is compatible with a large variety of systems by combining the switches and functions described in the following. 1Fuse 40 A . 1 : KAC-849 30 A . 1 : KAC-749S If you can’t find the specified capacity fuse at your store etc., consult your Kenwood dealer. 2Battery terminal 3Ground terminal 4Power control 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 high-output monaural amplifier, bridged connections are used. (Make connections to the LEFT channel (+) and the RIGHT channel (–) SPEAKER OUTPUT terminals.) 6INPUT 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. The sensitivities of amplifiers A and B can be adjusted independently regardless of the position of the input selector switch. Use the diagram on the right as a guide. For the pre-output level or the maximum power output, refer to the “Specifications” in the instruction manual of the center unit. 7FILTER FREQUENCY control When the FILTER switch is set to the HPF (High- Pass Filter) or LPF (Low-Pass Filter) position, the threshold frequency can be adjusted with this control. 8RCA 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. 9Amplifier A/B LINE IN terminals 0LINE OUT terminal These jacks output respectively the signals input to amplifiers A and B. They always output the stereo signals regardless of the position of the OPERATION switch. !Speaker level input terminals @BASS BOOST switch When the switch is in “ON” position, the bass is boosted by 6 dB. The bass boost applies only to the B amplifier. #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 FILTER 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 FILTER FREQUENCY control. The speaker output is automatically turned monaural (L+R). $OPERATION switch The amplification methods of the signals input to amplifiers A and B can be selected independently according to the setting of this switch. • 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 switch This switch selects the input method of the signals to be amplified by amplifiers A and B. • A B position: Amplifies both of the signals input to amplifiers A and B. • A position: Amplifies only signal input amplifier A with both amplifiers A...
