NOTE Refer to "Specifications" on the center unit's instruction manual about the pre-out level. 4 OPERATION switch This switch is used to select the operation mode of the amplifier. • STEREO position: The amplifier can be used as a stereo amplifier. • 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 monaural amplifier. (The input right signal is not output.) 3 FILTER switch This switch allows to apply high-pass or low-pass filtering to the speaker outputs. • HPF (High-Pass Filter) position: The filter outputs the band of higher frequencies than the frequency set with the HPF FREQUENCY control. • OFF position: The entire bandwidth is output without filtering. • 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 turned monaural (L+R) and the bass boost function is activated. 9 HPF FREQUENCY control Sets the cutoff frequency when the FILTER switch is set to HPF. 8 LPF FREQUENCY control Sets the cutoff frequency when the FILTER switch is set to LPF. 1 INFRASONIC FILTER switch When this switch is ON, the frequencies which are below the audible range and therefore inaudible are cut off so that the quality of the audible frequencies can be improved. 2 B.M.S.(Bass management system) switch Bass boost centered on the frequency set by the B.M.S. FREQUENCY control. • +12 position: Bass boost +12 dB • OFF position: Bass boost OFF • REMOTE position: Controls the B.M.S. from the Kenwood center unit. (Refer to page 5) 6 B.M.S. FREQUENCY control When the B.M.S. switch is set on "+12dB"/ "REMOTE" the emphasized center frequency is adjusted. 7 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. 4 English
