User manual KENWOOD KA-S10

[. . . ] · When a ground wire of the center unit (cassette receiver, CD receiver, etc. ) or this unit is not connected to a metal part serving as an electrical ground passing electricity to the battery's negative - terminal. Wiring · 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. [. . . ] 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 8 mm² (AWG 8) 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. 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. 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. · The impedance of the speakers that are going to be connected should be 2 or greater (for stereo connections), or 4 or greater (for bridged connections). 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. 4 4 4 4 8 2 Combined impedance 2 English Installation Accessories Part name Self-tapping screws (ø5 × 18 mm) Terminal cover (Power terminal) Speaker level input cable Hexagon Wrench External View Number of Items 4 1 1 1 KA-S10 only Part name Remote cable Remote controller Mounting bracket Self-tapping screws (ø2. 6 × 12 mm) NOTE External View Number of Items 1 1 1 2 · The rear side cover is fixed and cannot be removed. Installation procedure 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. 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. 2CAUTION Front side cover Hexagon socket head cap screw (M4 × 8 mm) Hexagon Wrench Cooling fan Self-tapping screw (ø5 × 18 mm) Installation board, etc. (thickness : 15 mm or more) Remote controller (KA-S10 only) Mounting bracket Remote controller · Do not install in the below locations; (Unstable location, In a location that interferes with driving, In a location that gets wet, In a dusty location, In a place that gets hot, In a place that gets direct sunlight, In a location that gets hit by hot air) · Do not install the unit under the carpet. Set to this position and make bridged connections to use as a high-power monaural amplifier. (The input right signal is not output. ) 8 RCA cable ground lead terminal When using an RCA cable with a ground lead attached, connect the ground lead to this terminal. & 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 Controls the unit power. Be sure to connect it with all the systems. 9 LINE IN terminal 0 LINE OUT terminal The signal that's input from the line input terminal is output. 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. !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. (See page 2) For the pre-output level or the maximum power output, refer to the <Specifications> in the instruction manual of the center unit. * BOOST LEVEL (Bass boost level) control (KA-S10 only) Sets the level by which the low frequency range should be boosted. · 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 @ BASS BOOST LEVEL control (KAC-7202 only) Sets the low frequency level to be compensated. ( FREQUENCY (Bass boost frequency) control (KA-S10 only) Sets the center frequency around which the low frequency range should be boosted. # 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. The rated input of the speakers should be no less than the maximum output of the amplifier. [. . . ] Otherwise malfunction may result. · HPF (High-Pass Filter) position: The filter outputs the band of higher frequencies than the frequency set with the "HPF FREQUENCY" control. 6 REMOTE terminal (KA-S10 only) Connects the Remote cable. NOTE · OFF position: The entire bandwidth is output without filtering. Use the Remote cable of the accessory. 7 Speaker level input terminals NOTE · 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). · 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 English 5 System examples 2-channel system High-power 2-channel subwoofer system Left subwoofer (Bridged) CENTER UNIT Right subwoofer (Bridged) Left speaker CENTER UNIT Right speaker 2-channel + Subwoofer system Left speaker (High pass) CENTER UNIT Right speaker (High pass) Subwoofer (L + R) (Bridged) Tri-mode (High pass) Subwoofer (L + R) (Bridged) Principle of Tri-mode Method of frequency band division using a coil and capacitor. . . in case of 6dB/oct.
