INTRODUCTION w BASS EXTENSION ON/OFF When pushed in (ON), this feature boosts the bass frequency of the left and right main channels by +6 dB (60 Hz) while maintaining overall tonal balance. This boost is useful if you do not use a subwoofer. However, this boost may not be noticeable if the main speakers are set to "SMALL" and the bass output mode is set to "SW." e PROGRAM q/w Selects the sound field program (see page 46). Selecting a sound field program turns on the effect. r BALANCE Controls the balance of the sound levels coming from the left and right main speaker(s). Setting this control to the center position is appropriate for most situations. t VOLUME Controls the output level of all audio channels. This does not affect the REC OUT level. y BASS Adjusts the low frequency response for the left and right main speaker channels. Turn the control to the right to increase the low frequency response and turn the control to the left to decrease the low frequency response. Caution • If you increase or decrease the low frequency sound to an extreme level, the tonal quality from the center, front effect, rear center, and rear speakers may not match that of the left and right main speakers. u PHONES Outputs audio signals for private listening using headphones. Cautions • When you connect headphones, no signals are output to the PREOUT jacks or the speakers. • When the signal input into the 6CH INPUT jack is being played back, only the left and right channel signals are output through the headphones. i TREBLE Adjusts the high frequency response for the left and right main channels. Turn the control to the right to increase the high frequency response and turn the control to the left to decrease the high frequency response. Caution • If you increase or decrease the high frequency sound to an extreme level, the tonal quality from the center, front effect, rear center, and rear speakers may not match that of the left and right main speakers. o VIDEO AUX Inputs audio and video signals from a portable external source such as a video camera. p REC OUT/ZONE 2 Selects the source you want to direct to the audio/video recorder and ZONE 2 outputs independent of the source you are listening to in the main room. When set to the SOURCE/REMOTE position, the input source is directed to all outputs.
