You use the FILTER switch to select the filter, as follows. OFF SUB WOOFER LOW CUT OFF Do not use any filter. SUBWOOFER..... Use a low-pass filter. The amplifier outputs the frequencies that are lower than the cutoff set by the FREQUENCY adjustment knob. LOW CUT Use a high-pass filter. You can use this setting to filter out unneeded low or subsonic frequencies. If you select SUBWOOFER or LOW CUT, you can then use the FREQUENCY adjustment knob to adjust the cutoff frequency. The adjustment range is 25 Hz to 150 Hz. Cutoff frequency 2 ON/OFF switch If you set this switch ON, the amplifier adds low-frequency compensation so as to enhance speaker output. The results (the actual change in the low-frequency balance) will vary accord- ing to the speaker type. Note that this switch is effective only if the FILTER switch is set to OFF. NOTE: This feature provides improved frequency reponse on speakers such as the YAMAHA S112 and S115. 3 INPUT jacks (Channels A, B) Two jack types are provided for each channel.
