Manual abstract: user guide KENWOOD KAC-HQR8400
Detailed instructions for use are in the User's Guide.
[. . . ] • When the unit malfunctions and a DC signal is sent to the speaker output.
NOTE
• If you experience problems during installation, consult your Kenwood dealer. • If the unit does not seem to be working right, consult your Kenwood dealer.
• Take the battery wire for this unit directly from the battery. If it’s connected to the vehicle’s wiring harness, it can cause blown fuses etc. • 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 the range of 14 mm2 (AWG 6) to 21 mm2 (AWG 4). • 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.
Wiring
Speaker Selection
• The rated input power of the speakers that are going to be connected should be greater than the maximum output power (in Watts) of the amplifier. Use of speakers having input power ratings that are less than the output power of the amplifier will cause smoke to be emitted as well as damage. When more than one set of speakers are going to be used, calculate the combined impedance of the speakers and then connect suitable speakers to the amplifier.

Since there are large variety of settings and connections possible according to applications, read the instruction manual well to select the proper setting and connection. 1. Remove the ignition key and disconnect the negative · terminal of the battery to prevent short circuits. 6. Connect the power wire, power control wire and grounding wire following this order. Insert the conductor of the wire in the terminal hole, and then tighten the screw.

@ LPF(Low-Pass Filter) FREQUENCY control # ISF (infrasonic filter) control
This control adjusts the frequency band output from this unit. Ultralow frequencies that cannot be reproduced even by a subwoofer speaker do not become sound but become unnecessary oscillations, which affect the sound by causing distortion, etc. Setting this control cuts the frequencies below the respective frequency. This improves the reproduction performance of the speakers by eliminating unnecessary oscillations which will not become sound. Set this control according to the pre-output level of the center unit connected with this unit.
NOTE
If you can’t find the specified capacity fuse at your store etc. , consult your Kenwood dealer.
