RETAIN INSTRUCTIONS - The operating instructions should be retained for future reference. HEED WARNING - All warnings on rhe appliance and in the operating instructions should be adhered to. FOLLOW INSTRUCTIONS - All operating and use instructions should be followed. WATER AND MOISTURE - The appliance should not be used near water - for example. near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, etc. LOCATION - The appliance should be installed in a stable location. WALL OR CEILING MOUNTING - The apptiance should not be mounted to a wall or ceiling. VENTILATION - The appliance should be situated so that its loca- tion or position does not interfere with its proper ventilation. For example, the appliance should not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or, plac- ed in a built-in installation. such as a bookcase or cabinet that may impede the flow of air through the ventilation openiigs. HEAT.- The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (in- cluding amplifiers) that produce heat. POWER SOURCES - The appliance should be connected to a power supply only of the type described in the operating instruc- tions or as marked on the appliance. POWER-CORD PROTECTION - Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance.
CLEANING - The appliance should be cleaned only with a polishing cloth or a soft dry cloth. Never clean with furniture wax, benzine, insecticides or other volatile liquids since they may corrode the cabinet. POWER LINES - An outdoor antenna should be located awav from power lines.
NONUSE PERIODS - The power cord of the appliance should be unplugged from the outlet when left unused for a long period of time. OBJECT AND LIOUID ENTRY - Care should be taken so that ob- jects do not fall and liquids are not spilled into the enclosure through openings. DAMAGE REOUIRING SERVICE - The appliance should be ser- viced by Pioneer authorized service center or qualified service per- sonnel when: o The power-supply cord or the plug has been damaged; or o Objects have fallen, or liquid has been spilled into the appliance; or o The appliance has been exposed to rain; or . The appliance does not appear to operate normally or exhibits a marked change in performance; or o The appliance has been dropped; or the enclosure damaged. SERVICING - The user should not attempt to service the appliance beyond that described in the operatirig instructions. For all other servicing, contact the nearest Pioneer authorized service center.

FEATURES
All-Electronic Reverberation Amplifier
This is an all-electronic reverberation amplifier which in-
corporates an audio-use delay element known as a buck-
et brigade device (BBD). Unlike conventional mechanical
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
amplifier. One mode, known as EFFECT-1, is the so-
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.
REAR PANEL FACILITIES
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
time is long, the flickering intervals will increase, and
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 REVERBERATTON INPUT JACKS
Connect these jacks to the TAPE REC jacks on the
stereo amplifier or to the PREAMP OUT (OUTPUT)
jacks on the preamplifier.
@ nevenBERATroN ourPUT JAcKs
Connect these jacks to the TAPE PLAY jacks on the
stereo amplifier or the the POWER AMP lN (INPUT)
jacks on the power amplifier.
@ rnpe REc JAcKS
Connect these to the INPUT (REC) iacks on the tape
deck.
@ rnpe PLAY JAcKs
Connect these to the OUTPUT (PLAY) jacks on the
tape deck.
@ nrreruuAToR swrrcH
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.
NOTE:
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.
AC OUTLET
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
on the model SR-9 (UNSWITCHED). The maximum
power capacity is 100W and so do not connect electri-
cal appliances with a power capacity exceeding this
value.
