FEATURES
All-Electronic Reverberation Amplifier
This is an all-electronic reverberation amplifier which in-
corporates an audio-use delay element known as a buck-
e t b r i g a d e d e v i c e ( B B D ) . U n l i k e c o n v e n t i o n a l m e c h a n i c a l
reverberation amplifiers, this particular unit is not in the
least affected by external vibration or fluctuations in the
reverberation effect.
Selection between Two Types of Reverberation
Effect
You can choose freely between two modes with this
a m p l i f i e r . O n e m o d e , k n o w n a s E F F E C T - 1 , i s t h e s o -
called "echo" mode when the reverberation components of
the original sound are made to last for a long time - a
feature which is effective in large halls. The other mode,
known as EFFECT-2, refers to a single reverberation
component which is generated to turn a solo vocal into a
chorus or duet. Make the most of these two effects to
derive more enjoyment and satisfaction from your music
sou rce.

Visually Attractive Reverberation Effect Indicator
This indicator is designed to express the reverberations
produced visually. The flickering of the green rings of
light indicate the effect at a glance. When the reverberation
t i m e i s l o n g , t h e f l i c k e r i n g i n t e r v a l s w i l l i n c r e a s e , a n d
conversely when the time is short, these intervals will
decrease. Another function of the display is to display the
strength of the reverberations: the more revebreration com-
ponents, the brighter the rings of light.
TIME and DEPTH Controls to Adjust Reverbe-
ration Effect
This reverberation amplifier comes with two handy con-
trols: the TIME control that allows the delay time to be
adjusted continuously and the DEPTH control which
allows the depth of the reverbration to be adjusted con-
tinuously. Using the two knobs in combination makes it
easy to produce the desired reverberation effect in line
with the music source which you are listening to.
c R EV E R B E RA T T O N I NPU T JACK S
Connect these jacks to the TAPE REC jacks on the
stereo amplifier or to the PREAMP OUT (OUTPUT)
jacks on the preamplifier.

Connect these jacks to the TAPE PLAY jacks on the
s t e r e o a m p l i f i e r o r t h e t h e P O W E R A M P l N ( I N P U T )
jacks on the power amplifier.

Connect these to the INPUT (REC) iacks on the tape
deck.

Connect these to the OUTPUT (PLAY) jacks on the
tape deck.

This is used to attenuate the model SR-9's inputsignals.
It is normally set to OdB (released position). When
using the model to reverberate the sound of a program
source having an extremely wide dynamic range, such
as a live recording, or when the sound appears to be
distorted with the switch set at the OdB position,
depress this switch and set it to the -6dB position.
N O T E :
The maximum rated input of the model SB-9 r's 2V. When it
is being used between the PREAMP OUT jacks of the pre-
amplifier and the PowER AMP lN jacks of the power ampli-
fier, set this switch beforehand to -6dB if the output level of
the preamplifier
will exceed 2V.
A C O U T L E T
This is an auxiliary power outlet. Connect the power
plug of .your tape deck or other stereo hi-fi component
to this outlet. lt is not coupled with the power switch

power capacity is 100W and so do not connect electri-
cal appliances with a power capacity exceeding this
v a l u e .
