The Digital “Pure Class A” Integrated Amplifier RS-A1 or the Digital “Class A”
Integrated Amplifier RS-A2 are power amplifiers built into the digital network of
the ODR system*. High quality sound can be expected from these classes, since
the RS-A1 is a pure class A amplifier and the RS-A2 is a class A amplifier.
Functions:
+ 3-band parametric equalizer
— Ocontro!
+ Selectable digital network
— 36 dB/oct. slope
— Time alignment
+ Parametric bass/treble control
+ Listening position selector
+ 15 W x 2/60 W x1 “Pure Class A” Integrated Amplifier (RS-A1)
50 W x 2/160 W x 1 “Class A” Integrated Amplifier (RS-A2)
> If the RS-A1/RS-A2 is used with a Digital Equalizer RS-P1 or RS-P50, the 31- or 16-band
graphic equalizer has priority over the 3-band parametric equalizer of the RS-A1/RS-A2.
> Read the manual of the ODR System Control Center RS-K1 or RS-D2 on how to operate the
system.

Dear Custener:
Selecting fine audio equipment such as the unit
you’ve just purchased is only the start of your musical
enjoyment. Now it’s time to consider how you can
maximize the fun and excitement your equipment
offers. This manufacturer and the Electronic Industries
Association’s Consumer Electronics Group want you
to get the most out of your equipment by playing it ata
safe level. One that lets the sound come through loud
and clear without annoying blaring or distortion—and,
most importantly, without affecting your sensitive
hearing.
Sound can be deceiving. Over time your hearing
“comfort level” adapts to higher volumes of sound. So
what sounds “normal” can actually be loud and
harmful to your hearing. Guard against this by setting
your equipment at a safe level BEFORE your hearing
adapts.
To establish a safe level:
® Start your volume control at a low setting.
® Slowly increase the sound until you can hear it
comfortably and clearly, and without distortion.
Once you have established a comfortable sound
level:
® Set the dial and leave it there.
Taking a minute to do this now will help to prevent
hearing damage or loss in the future. After all, we want
you listening for a lifetime.
We Want You Listening For A
Lifetime
Used wisely, your new sound equipment will
provide a lifetime of fun and enjoyment. Since hearing
damage from loud noise is often undetectable until it is
too late, this manufacturer and the Electronic Industries
Association’s Consumer Electronics Group
recommend you avoid prolonged exposure to
excessive noise. This list of sound levels is included for
your protection.
Decibel
Level Example
30 Quiet library, soft whispers
40 Living room, refrigerator, bedroom away
from traffic
50 Light traffic, normal conversation, quiet
office
60 Air conditioner at 20 feet, sewing machine.
70 Vacuum cleaner, hair dryer, noisy restaurant
80 Average city traffic, garbage disposals, alarm
clock at two feet.
THE FOLLOWING NOISES CAN BE
DANGEROUS UNDER CONSTANT
EXPOSURE
90 Subway, motorcycle, truck traffic, lawn
mower
100 Garbage truck, chain saw, pneumatic drill
120 Rock band concert in front of speakers,
thunderclap
140 Gunshot blast, jet plane
180 Rocket launching pad

(4, WARNING
To prevent electric shock:
+ Do not touch the amplifier with wet hands.
Otherwise you may get electric shock. Also,
do not touch the amplifier when it is wet.
Use moderate volume while driving:
+ For traffic safety and to maintain safe driving
condition, keep the volume low enough so
that you can still hear normal traffic sound.
High temperature of the RS-A1:
+ The RS-A1 will remain hot (176 degrees
Fahrenheit or higher) during operation of the
QDR System and until approximately 10
minutes after use.
Therefore:
— Do not touch the amplifier with hands to
avoid burns.
— Do not place objects susceptible to heat
{e.g. vinyl products) near the amplifier to
avoid deformation of such objects.
— To ensure proper heat dissipation, never
place objects on or around the amplifier.
For safe operation:
+ To prevent malfunction and accidents, check
the connections of the power supply and
speakers if the fuse-of the special red battery
lead or the amplifier blows. Detect the cause
and solve the probiem, then replace the fuse
with another one of the same size and rat-
ing. (The fuse of the special red battery lead
has a rating of 30 A for both the RS-A1 and
the RS-A2. The fuse of the amplifier has a
rating of 20 A for the RS-A1, and 30 A for the
RS-A2.} i
+ To prevent malfunction to the amplifier and
speakers, the protective circuit will cut the
power supply to the amplifier (sound will
stop) when an abnormal condition occurs. In
such a case, switch the power of the system
OFF, check connection of the power supply
and speakers. Detect the cause and solve the
problem.
+ Contact with your dealer if you cannot
detect the cause.
Precautions for connection and instal-
lation:
+ To prevent electric shock or short-circuit dur-
ing connection and installation, be sure to
disconnect the negative (-) terminal of the
battery beforehand.
+ Be sure to use the special red battery lead
supplied with the amplifier and connect
directly to the battery. Use the supplied
black ground lead and connect to the vehicle
body. (The supplied special red battery and
ground leads are designed so that the ampli-
fier can be connected safely.}
+ Confirm that no parts are behind the panel
when drilling a hole for installation of the
amplifier. Be sure to protect all cables and
important equipment such as fuel pipes,
brake pipes and power supply harness from
damage.
+ To prevent electric shock, do not install the
amplifier to places where it might get in con-
tact with liquids.
* The power consumption of the RS-A1 is very
high. To avoid overload to the battery, do
not connect more than two RS-Ai amplifiers
to an ODR System.
+ To ensure proper heat dissipation of the
amplifier, take care of the following during
installation.
— Allow adequate space on and around the
amplifier for proper ventilation.
Particularly, do not block the diffuser of
the cooling fan located on the top of the
amplifier.
— Do not cover the amplifier with a floor
mat or carpet.

> To ensure better sound quality, PIONEER recommends to connect the speakers to the
Digital Amplifier in the sequence of high-range, mid-range, fow-range, and subwoofer
modes. Also, connect the subwoofer to the front OUT. (Although the subwoofer is connect-
ed to the front OUT, it may be installed to either front or rear.)

@ Address setting
Multiple audio units* such as the RS-A1/RS-A2 Amplifier and Digital Equalizers
can be connected to the ODR System. Therefore, each audio unit must be
assigned an address as identification number (1 to 8).
Set the address according to the following rules:
+ Seta unique address to each audio unit.
+ The first audio unit must be assigned to Address 1.
+ Ifthe Digital Equalizer RS-P1 is included among the audio units, it must be
assigned as Address 1. Therefore, assign Addresses 2 to 8 to other audio units.
> The RS-P1 is fixed to Address 1, and this setting cannot be changed.
lf the Digital Equalizers RS-P50 is used instead of the RS-P1, assign Address 1 to
one of the RS-P50 equalizers.
@ Network mode setting
Set the mode for the network according to the purpose of the speakers to be con-
nected,
THRU mode (Frequency: 20 — 20,000Hz)
Set to this mode when the speaker to be connected will be used in full-range.
> In this mode, the functions of the network are disabled.
> This mode is invalid if the RS-P1 or RS-P50 Digital Equalizer is used in the ODR System.
> When using the ODR System in this mode, other digital amplifiers (RS-A1/RS-A2) must also
be set to THRU mode.
S.W. - MONO (subwoofer monaural) mode (Frequency: 20 — 250Hz)
Set to this mode when the speaker to be connected will be used as subwoofer to
output monaural sound.
S.W. - L (subwoofer L channel) mode (Frequency: 20 — 250Hz)
Set to this mode when the speaker to be connected will be used as subwoofer to
output L (left) channel sound.
S.W. - R (subwoofer R channel) mode (Frequency: 20 — 250Hz)
Set to this mode when the speaker to be connected will be used as subwoofer to
output R (right) channel sound.
S.W. - ST (subwoofer stereo) mode (Frequency: 20 — 250Hz)
Set to this mode when the speakers to be connected will be used as subwoofers
to output stereo sound.
*Audio units
By definition, audio units are Digital Amplifiers, Digital
Equalizer and other audio equipment for the ODR
System including the following:
— Dual 1/3 Octave Digital Equalizer [RS-P1]
— Universal Digital Preamp/Equalizer [RS-P50]
