OPERATION
P R I O R T O S W I T C H I N G P O W E R O N
Set the controls and switches to the following positions
before operating the model SR-9.
1. Set the reverb time control to the '5' position.
2 . S e t t h e d e p t h c o n t r o l t o t h e ' 0 ' p o s i t i o n .
3. Depress the reverberation off switch.
4. Set the tape monitor switch to OFF (released).
5. Set the tape monitor switch (which is related to the
TAPE jacks connecting the SR-9) on the stereo ampli-
f i e r t o O N .
N O T E :
Even when the SB-9's power switch is at OFF, the INPUT
signal will bypass the reverberation circuit and it will be fed out
to the OUTPUT iacks and TAPE REC jacks when the reverbe-
ration off switch is depressed.
Operation procedure
1. Play the program source on the stereo amplifier, and
listen to the sound without adding the reverberation
effect.
2. Depress the reverberation on switch (ON).
3. Rotate the depth control clockwise, increase the reverbe-
ration components and adiust to the preferred level.
The level fluctuations of the reverberated sound will
make the reverberation indicator's light ring weak and
strong. Rotate the depth control and adjust so that the
light ring fluctuates widely between strong light and
weak light. Remember that when the light ring of the
reverberation indicator comes on strong, the reverbe-
ration effect is excessive.
4. Rotate the reverb time control, try lengthening or
shortening the delay time, and set this control to the
optimum position.
N O T E :
Select reverberation EFFECT
1 or EFFECT 2 using the reverb
time control,
in accordance
with
the program
source which
you intend to reproduce.

The SR-9 allows a selection between two types of
reverberation eff ects.
EFFECT 1 (with the reverb time control depressed)
A normal reverberation is produced. This is the so-
called echo mode, and the reverberation component of the

for performances in a hall. The reverberation time is de-
fined as the time taken for the reverberation component to
d r o p 6 0 d B ( o n e - m i l l i o n t h ) w i t h r e s p e c t t o t h e o r i g i n a l
sound. Using both the reverb time and depth controls, it
is possible to adjust the reverberation time between 0 and
3 seconds.

EFFECT 2 (with the reverb time controll pulled out)
As shown in Fig. 5, only one reverberation component is
generated with respect to the original sound. Since only this
single component is added to the reproduced sound, the
effect sounds like a chorus. In order to make the most of
the EFFECT 2 facility, it is recommended that the reverb
