Familiarity with installation and operation procedures will help you obtain the best performance from your new power amplifier. For your records Record the serial number, found on the back of the unit, in the spaces designated on the warranty card, and in the space provided below. Refer to the model and serial numbers whenever you call upon your KENWOOD dealer for information or service on the product. [. . . ] This setting is valid for both the amplifier A and B. CH LPF FREQUENCY control This control adjusts the frequency band output from this amplifier SUB. € STEREO position: The amplifier can be used as a stereo amplifier. 7 INPUT SELECTER switch (AB/A) This switch toggles the input signal of amplifier B. € MONO (Lch) position: Amplifies the signal input from the left side only. Set to this position and make bridged connections to use as a high-power • AB position: The input for terminal A is output from amplifier A, while the input for terminal B is output from amplifier B. 4 English Removing the cover Hexagon Wrench Tighten Loosen !€ A position: The input for terminal A is output from amplifiers A and B. Switch is set in the remote position, the bass boost amount and frequency offset can be controlled from the center unit. (AB/SUB) This switch toggles the input signal of amplifier SUB. € AB position: The input for terminals A and B input is mixed and output from amplifier SUB. € Bass boost Center unit display "Flat"/ "OFF"/ "1" "+6"/ "1"/ "2" "+12"/ "2"/ "3" "+18"/ "3"/ "4" Center unit display "Normal" Setting Bass boost OFF (Flat) Bass boost +6 dB Bass boost +12 dB Bass boost +18 dB • SUB position: The input for the SUB terminal is output by amplifier SUB. (Bass management system) switch Bass boost centered on the frequency set by the B. Switch is set on "+12dB"/ "REMOTE" the emphasized center frequency is adjusted. For the center unit control method and setting display, refer to the Instruction Manual for the center unit. There may be cases when the center unit can’t set the "Bass boost +18dB" or "Frequency Offset". 9 V-COLOR (Variable color) button Select the ON color for the indicator. Every time the button is pressed, 7 fixed colors and the variable color change. The color can’t be set when the indicator is blinking. You are notified of the unit’s condition and malfunction (Protection function) by the indicator. When operation is normal NOTE The color you want can be selected with the variable color button. € The color blinks blue – When during operation – When the center unit/B. [. . . ] 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 2Ω or greater (for stereo connections, amplifier SUB), or 4Ω 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. (High pass) 159000 (µF) fc x R 159 x R L= (mH) fc C= fc=Cut of Frequency (Hz) R=Speaker Impedance (Ω) Frequency ●Example: When it is required to set a crossover frequency of 120 Hz using speakers with an impedance of 4 ohms.
