CONNECTIONS
CONNECTION TO THE PREAMPLIFIER UNIT
1.
Connect the INPUT terminals of D-23 to the
OUTPUT
terminals
Fig.
5),
making sure that left (L) and right
channels are connected correctly. In the D-23,
all upper row terminals are for left channel, and
all lower row terminals are for right.
2. Connect the D-23 power supply cord to the
switched AC outlet on the rear panel of the
preamplifier.
Turn D-23's power switch ON. All consequent
turning ON and OFF of the preamplifier power
supply
switch will thus automatically switch
D-23 ON and OFF.
CONNECTIONS TO POWER AMPLIFIER UNITS
1.
Connect each of the OUTPUT terminals (HIGH,
MID-HIGH, MID-LOW, and LOW) on the rear
panel of D-23 to the INPUT terminals of the
respective stereo power amplifiers (see Fig.
Be sure that left and right channels are con
nected correctly.
2. Now connect the power supply cord of each
power
amplifier
unit
(including the AC outlets on the rear panel of
the preamplifier) whose power output capacity
exceeds the maximum power consumption of
the power amplifier.

Loose connections may result in loss of sound,
generation of noise, or damage to the speakers.
When connecting to the speakers, make doubly

sure that the speaker's reproduction frequency
range corresponds to the correct output terminal
on the rear panel of the D-23. Incorrect connec

In order to protect the speakers against possible

rupture due to unexpected noise or extraneous
frequencies beyond the speaker's range it is
recommended that a capacitor be inserted be
