7 REC SELECTOR switch /indicator(For TAPE 1/CDR/MD terminals)
This switch is used to select the recording source component. The signal from the selected component is output at the TAPE1/ CD-R/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/CD-R/MD is output. Set to this position when not recording; the cassette deck will be disconnected, improving sound quality. NOTE: The function selected using the INPUT SELECTOR knob will be recorded irrespective of the position of the REC SELECTOR switch (TAPE 2 MONITOR terminals).

(Volume indicator lights) [DIRECT] Use this button when you do not wish to pass the output from input terminal equipment through the various frequency adjusting circuits (BASS, TREBLE, BALANCE, LOUDNESS). On : The indicator lights. The signals input through the input terminals are reproduced without passing through the various frequency adjusting circuits. This results in flat, pure sound which is a more faithful reproduction of the input source. Off : The indicator goes out. The signal passes through the various frequency adjusting circuits. [SB MODE] The SB mode is a special mode in which the amplifier does not accept remote control except power ON/OFF (But all of the facilities can be controled by manual as same as SB mode OFF.). Fix the VOLUME control near the center position.In this mode, the set can be used as a power amplifier which amplifies the LINE/SURROUND BACK input (the function name is LINE/SB) with a input sensitivity of 1V. For example, when the set is combined with one of Pioneer's Surround Back compatible receiver, the set can be used sa the Surround Back amplifier. (For details, please refer to the instruction manual of the receiver.)
