[. . . ] Model KAC-6201 Serial number © B64-2564-00/00 (KV/EV) Safety precautions 2WARNING Wiring To prevent injury or fire, take the following precautions: · When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with a 3mm2 (AWG12) or more to prevent wire deterioration and damage to the wire coating. · To prevent a short circuit, never put or leave any metallic objects (such as coins or metal tools) inside the unit. · If the unit starts to emit smoke or strange smells, turn off the power immediately and consult your Kenwood dealer. · Do not touch the unit during use because the surface of the unit becomes hot and may cause burns if touched. 2CAUTION To prevent damage to the machine, take the following precautions: · Be sure the unit is connected to a 12V DC power supply with a negative ground connection. [. . . ] · To prevent a short circuit when replacing a fuse, first disconnect the wiring harness. NOTE · If a buzzing noise is heard from the speakers when the engine is running, connect a line noise filter (optional) to each of the battery wire. · Do not allow the wire to directly contact the edge of the iron plate by using Grommets. · Connect the ground wire to a metal part of the car chassis that acts as an electrical ground passing electricity to the battery`s negative terminal. · Be sure to install a protective fuse in the power cord near the battery. The protective fuse should be the same capacity as the unit's fuse capacity or somewhat larger. · For the power cord and ground, use a vehicle type (fireproof) power wring cord with a current capacity greater than the unit's fuse capacity. (Use a power wiring cord with a diameter of 3 mm2 (AWG 12) or greater. ) · When more than one power amplifier are going to be used, use a power supply wiring wire and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier. Installation procedure 1. Remove the ignition key and disconnect the negative - terminal of the battery to prevent short circuits. Connect the power wire, power control wire and grounding wire following this order. Connect the negative - terminal of the battery. 2WARNING Accessories Part name Terminal cover (Power terminal) Self-tapping screws (ø4 × 16 mm) Speaker level input cable External View Number of Items 1 4 1 Installation Since the power amplifier has no parts which require operation, it can be installed at a position away from the driver's seat without any hindrances. As generally accepted positions for its installation, places such as inside the trunk, etc. · 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. Self-tapping screw (ø4 × 16 mm) Cleaning the unit If the front panel gets dirty, turn off the power and wipe the panel with a dry silicon cloth or soft cloth. 2CAUTION Power terminal (234) Do not wipe the panel with a hard cloth or a cloth dampened by volatile solvents such as paint thinner and alcohol. They can scratch the surface of the panel and/or cause the indicator letters to peel off. Connect to their respective terminals the power supply wire, and ground wire, all of which pass through the associated terminal cover. Once the connections are complete, place the cover on the terminal section.

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. @ NOTE # @ FILTER switch These switches allow filtering of the speaker output signals. 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. [. . . ] (Frequencies above 80 Hz are cut. ) The Lch and Rch will be mixed before output even if the operation switch is set to STEREO. 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. 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 amplifier stops operating. · When the unit malfunctions and a DC signal is sent to the speaker output. [. . . ]
