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
