@ POWER SWITCH (POWER)/INDICATOR
When this switch is set to the ON position, power is supplied
to the unit's main circuits and the indicator lights. The unit's
power switch is geared to selecting the transformer's secon-
dary and so even at the STAND-BY position, the unit's cir-
cuitry will work as long as the power cord is connected to the
power outlet.
Disconnect the power cord from the power outlet when you
do not plan to use the unit for a long period of time.
@ EQUALIZER SWITCH
This switch is pressed to compensate for the frequency
response of the signals entering the EQUALIZER INPUT ter-
minals. The compensated signals are then output as the out-
put signals from the EQUALIZER OUTPUT terminals.
© EQUALIZER RECORD SWITCH
Press this switch to record the signals which have been com-
pensated for by the SG-540. The compensated signals are
output from both the EQUALIZER OUTPUT terminals and
ADAPTOR/TAPE REC terminals.

@ TAPE MONITOR SWITCH
Press this switch when using a stereo component connected
to the rear panel ADAPTOR/TAPE terminals. At all other
times, ensure that the switch is at the released position.
@ OCTAVE CONTROLS
Move these controls above or below the center{zero) posi-
tion to boost or attenuate the corresponding frequency
band. The seven frequency bands are centered at 60 Hz, 150
Hz, 400 Hz, 1 kHz, 2.4 kHz, 6 kHz and 15 kHz.
The indicator of each control serves as a guiddine for the
changes in the frequency response. It lights when the
EQUALIZER switch is pressed.
