[. . . ] KS-AR8001D LVT1811-001A [J] POWER AMPLIFIER: INSTRUCTIONS AMPLIFICATEUR DE PUISSANCE: MANUEL D’INSTRUCTIONS When you use more than one KS-AR8000 series amplifier, you can pile up to three of them using the provided brackets and hex screws in two ways, X or Y. ENGLISH 1 Attach the provided spacers to the bottom of the amplifier (2 and 3). Spacer's bottom Bottom Thank you for purchasing an ARSENAL product. Please read all instructions carefully before operation, to ensure your complete understanding and to obtain the best possible performance from the unit. This unit is designed to be connected to subwoofers. 2 Fix the amplifiers on both sides with the brackets (I) as illustrated. • Be sure to mount the lowest amplifier (1) as illustrated on . • Before piling amplifiers as X, first make the connections for the power supply (see “POWER SUPPLY” below) and speakers (see “SPEAKER CONNECTIONS” on page 2). [. . . ] SUBSONIC filter controller Adjust the cutoff frequency (the subsonic filter rejects frequencies lower than the cutoff frequency) within the range of 20 Hz to 50 Hz. This control is preset to 20 Hz when the unit is shipped. Alternator noise is heard. • Keep the leads of the POWER terminals away from the RCA pin cords. • Keep the RCA pin cords away from other electrical cables in the car. • Connect the ground lead securely to a metal part of the car. • Make sure the negative speaker leads do not touch the car chassis. • Replace the plugs or use plugs with load resistors. • Connect a bypass capacitor across the accessory switches (horn, fan, etc. ). Noise is made when you connect the unit to an AM tuner. • Move all the leads of this unit away from the antenna lead. SPECIFICATIONS Power Output Signal-to-Noise Ratio 700 W RMS x 1 channel at 4 Ω and ≤ 1% THD + N 80 dBA (reference: 1 W into 4 Ω) Maximum Power Output Power Output Load Impedance Frequency Response Connecting the wired remote control unit—RM-RK130 (purchased separately) Using JVC’s wired remote control unit: RM-RK130, you can adjust the bass boost from your seat without having to adjust the BASS BOOST controller on the amplifier (see “CONTROLS” above). • Before piling amplifiers as X, first make the connections for the power supply (see “POWER SUPPLY” below) and speakers (see “SPEAKER CONNECTIONS” on page 2).

CAUTIONS AND NOTES This unit is designed to operate on 12 V DC, NEGATIVE ground electrical systems. • This unit uses BTL (Balanced Transformerless) amplifier circuitry, i. e. , floating ground system, so comply with the following: Do not connect the “·” terminals of the speakers to each other. Do not connect the “·” terminals of the speakers to the metal body or chassis. • Cover the unused terminals with insulating tape to prevent them from short circuiting. • When an extension lead is used, it should be as thick and short as possible; connect it firmly with insulating tape. • Be sure to leave an appropriate space between the antenna (aerial) and the wires of this unit. • When replacing the fuse, only use a 25 A fuse. • Do not let pebbles, sand or metallic objects get inside the unit. • To keep the heat dissipation mechanism running effectively, wipe the accumulated dust off periodically. • Listening to the tape, radio, CD or Digital Audio Player, etc. [. . . ] This control is preset to 50 Hz when the unit is shipped. PHASE switch Select either normal (NOM) or reverse (REV), whichever reproduces a better sound. This switch is preset to NOM when the unit is shipped. BASS BOOST controller Turning this boosts the 45 Hz frequency within the range of 0 dB to +18 dB. [. . . ]
