OPERATING INSTRUCTIONS

FEATURES

Op Amp Filter Circuits

Operational amplifier (Op Amp) integrated circuits make
up the special active filter networks for each band.
Performance is always stable, while the complete elimina-
tion of coils avoids aging variations due to temperature,
humidity and other ambient conditions. The high dynamic
range design provides low distortion over a wide band with
respect to any input signal.

2 Channel 12 Elements Graphic Equalizer

The graphic equalizer divides the audio frequency spec-
trum into 12 segments from I6Hz to 32kHz, with each
segment corresponding to an octave. Individual controls for
each segment provide continuous adjustment (from -IOdB
to +IOdB) and allow the sound to be contoured in order to
compensate for equipment and speaker characteristics,
listening room acoustics or personal preferences. Adjust-
ments can also be performed during recording.

Effective Tape Monitor and Equalizer Switches

Tape jacks are included for connecting a stereo tape
deck. In addition to input signal equalizing, simple switch
selection can provide equalizing for a tape playback signal
and recording of an equalized signal.

Easy-to-operate Panel Layout

Slide controls and push switches compose the operating
panel. The styling is both functional and attractive, making
this an excellent addition to a high performance audio
system in combination with Pioneer audio components.

The specifications of this model differ according to the

shipment destination.

0 For UK. (WB stamped on packing case): Power line
voltage is 240 volts.

0 For mainland Europe (WE stamped on packing case):
Power line voltage is 220 volts.

0 For destinations excluding above (R, R/G stamped on
packing case): A 2-point (I IOV-I2OV/22OV-24OV) volt-
age selector switch is provided on the rear panel, and an
AC conveneience outlet is provided on the rear panel.

For the sake of convenience, the illustrations and explana-
tions are based on the SG-9800/R, R/G.

Before turning on the power, please confirm the
setting of the line VOLTAGE SELECTOR switch
on the rear panel. If it is not set properly, change
the setting of it according to the LINE VOLTAGE
