Resumen del manual
(Frequencies above 80Hz are cut.) The Lch and Rch will be mixed before output even if the operation switch is set to STEREO. • OFF position: The original sound without filtering is output. n Full-range 4-channel + Subwoofer system 1.0 0.5 FILTER OPERATION OFF HPF STEREO MONO(Lch) LPF 0.3 MIN MAX INPUT INPUT SELECTOR CONTROL A SENSITIVITY(V) AA B CONTROL B 1.0 FILTER OPERATION 0.5 OFF (Lch) HPF LPF STEREO MONO 0.3 MIN MAX INPUT SENSITIVITY(V) CENTER UNIT Switch setting L LA B Power amplifier Front speaker Rear speaker Subwoofer System examples n High-pass + Subwoofer system INPUT SENSITIVITY(V) CONTROL OPERATION B CONTROL A (Lch) MONO MAXMIN 0.3 0.5 1.0 STEREO INPUT SENSITIVITY(V) MAXMIN 0.3 0.5 1.0 INPUT SELECTOR AA B LPF OFF FILTER HPF OPERATION MONO(Lch)STEREO LPF OFF FILTER HPF A B BRIDGED (High pass) CENTER UNIT Subwoofer (L + R) (Bridged) Switch setting n High-power 2-channel system INPUT SENSITIVITY(V) CONTROL OPERATION B CONTROL A (Lch) MONO MAXMIN 0.3 0.5 1.0 STEREO INPUT SENSITIVITY(V) MAXMIN 0.3 0.5 1.0 INPUT SELECTOR AA B LPF OFF FILTER HPF OPERATION MONO(Lch)STEREO LPF OFF FILTER HPF CENTER UNIT Switch setting L A B BRIDGEDBRIDGED Left speaker R Right speaker n Tri-mode L A B C LC INPUT SENSITIVITY(V) CONTROL OPERATION B CONTROL A (Lch) MONO MAXMIN 0.3 0.5 1.0 STEREO INPUT SENSITIVITY(V) MAXMIN 0.3 0.5 1.0 INPUT SELECTOR AA B LPF OFF FILTER HPF OPERATION MONO(Lch)STEREO LPF OFF FILTER HPF CENTER UNIT (High pass) Subwoofer (L + R) (Bridged) Switch setting l Principle of Tri-mode Method of frequency band division using a coil and capacitor•••in case of 6dB/oct. slope L C Crossover Frequency Frequency Coil (L): Passes low frequencies and blocks high frequencies. (Low pass) 0 dB Capacitor (C): Passes high frequencies and blocks low-3 dB frequencies. (High pass) 159000 C= (.F) fc x R fc=Cut of Frequency (Hz) 159 x R R=Speaker Impedance (.) L= (mH) fc l Example: When it is required to set a crossover frequency of 120 Hz using speakers with an impedance of 4 ohms. Prepare commercially-available coil and capacitor with the closest ratings to the results calculated from the formula above. The capacitor rating should be as close as possible to 331.25 (.F) and the coil rating should be as close as possible to 5.3 (mH). 2CAUTION • If you wish to bridge-connect a speaker, the speaker impedance must be no less than 4 ohms. Connecting a speaker with an impedance lower than 4 ohms may damage the unit. • Be sure to connect capacitors to speakers to which high frequencies will be passed. Failure to do so will result in a drop of the combined impedance with the subwoofer. • Ensure that the withstand voltage and current ratings of the capacitors (C) and coils (L) are sufficient. Connection n Power cable connection 2WARNING To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery’s positive terminal.

Once the connections are complete, place the cover on the terminal section. Wiring • 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 cable. • Do not allow the cord to directly contact the edge of the iron plate by using Grommets. • Connect the ground cable to a metal part of the car chassis that acts as an electrical ground passing electricity to the battery‘s negative -terminal. Do not turn the power on if the ground cable is not connected. • Be sure to attach a protective fuse into the battery cable close to the battery. Use a protective fuse having a capacity that is about 10 A higher than the maximum current drawn by the amplifier. • Use vehicle-type (fire-resistant) power supply wiring cable for the battery cable and the ground cable. The current capacity of the power supply wiring cable should be about 10 A higher than that of the protective fuse capacity (which means about 20 A higher than the maximum current drawn by the amplifier). • When more than one power amplifier are going to be used, use a power supply wiring cable and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier.
