(No sound will be heard if it is set to the on position. ) 3 Remote control sensor window 4 VOLUME control Use to adjust the volume level. NOTE: The TONE effect functions regardless of volume levels. 26 A-400X 7 REC SELECTOR switch /indicator(For TAPE 1/MD terminals) This switch is used to select the recording source component. The signal from the selected component is output at the TAPE1/ MD jacks for recording. To select a recording source component, press the REC SELECTOR switch so that the indicator of the desired source component lights up. When this switch is set to [TUNER] or [CD], the signal from the selected component can be recorded regardless of the input selector switch and TAPE2 MONITOR button settings. CD : To record from the equipment connected to the CD terminals. TUNER : To record from the equipment connected to the TUNER terminals. SOURCE : To record from the equipment selected by the INPUT SELECTOR knob. OFF : In this position, nothing from the REC terminals of TAPE 1/MD is output. Set to this position when not recording; the cassette deck will be disconnected, improving sound quality. - TREBLE tone control Use to adjust the high-frequency tone. The center position is the flat (normal) position.
