INSTALLATION AND MOUNTING
1. AMPLIFIER LOCATION
The REFERENCE amplifiers employ highly efficient circuitry and a unique
Chassisinkn” design to maintain lower operating temperatures. Additional
cooling may be required if the amplifier is located in a tightly confined area
or when driving especially low impedance loads at extremely high levels.
When mounting the amplifier, it should be securely mounted to either a
panel in the vehicle or an amp board or
rackthat
is securely mounted to the
vehicle. The mounting location should be either in the passenger
compartment or in the trunk
01
the vehicle, away from moisture, stray or
moving objects. and major electrical components. To provide adequate
ventilation, mount the amplifier so that there are at least two inches of freely
circulating air above and to the sides of it.
2. SIMTCHES
Set High Power/High Current and Coherent
Stereo”/Mixed-Mono/Bridged
Mono switches to the appropriate positions (see page 11).
3. MOUNTING THE AMPLiFlER
a. Using the amplifier as a template, mark the mounting surface.
b. Remove the amplifier and drill the holes.
c. Mount the amplifier to the surface using the provided hardware.
4.
WIRING
a. Run
and connect the audio signal and remote turn-on cables to the
amplifier from the source unit
b. Carefully run the positive cable from the amplifier to a fuse or circuit
breaker within 19” of the battery.
c.
Connect the fuse or circuit breaker to the battery. Leave the circuit
breaker off or the fuse out until
evelything
is bolted down.
d. Secure the ground cable to a solid chassis ground on the vehicle.
It may
be necessaty to sand paint down to raw metal for a good connection.
e.
Double check each and every connection!
f. Reconnect the fuse or circuit breaker.

POWW?
UP
Power up the system and look at the green and red
LEDs;
depending
on
the
configuration, one should be lit. There may be a 2 3
seconddelayfrom
the
time the the source unit is turned on to the time that the LED
on
the amp
turns on. which is normal. Once the amplifier power LED is on and the
source unit is playing, you should have sound coming from the speakers.

NOTE:
There may be a sizable spark when connecting Ihe
power
and
ground lead
to
the
amplifier for
Ihe
first
lime. This is caused by currenl rushing info the amplifier

LEVEL SETTING
The input levels are adjusted by means of the input level controls located on the
front of the amplifier. This is a unique dual-stage circuit that adjusts both level
and gain. This topology maintains better Signal to Noise ratios even when
using sources with minimal output. In the ideal situation, all components in the
audio system reach maximum undistotted output al the same time. The reason
is because an amplifier will only make what comes inlo it bigger. So. if you
send it a distorted signal from the head unit, the amplifier is going to amplify
distorted information. The same thing holds true if an outboard processor or
crossover begins to distort before you have maximum output from the amplifier.
By setting all components to reach clipping at the same time, you can maximize
the output of your system.
For the REFERENCE amplifiers, follow the below
procedure for the quickest, easiest means of setting the levels.
1.
Turn the amp’s input levels to minimum position (fully counter-clockwise).
2. Set source unit volume to approximately
34
of full volume.
3. While playing dynamic source material, slowly increase the amplifier’s
input level until a near maximum undistorted level is heard in the system.
CAUTION!
Prolonged listening af high lavels may
resolf
in hearing loss.
Even
lhough
your
new Soundstream REFERENCE amplifier sounds better than
anyrhing
you’ve
ever heard, exercise caulion ropravenr hearing damage.

PROTECTION ClRCUlTRY
lour
REFERENCE amplifier is protected against both overheating and short
circuits by means of the following circuits:
l Main power supply luses
*
Circuit breakers
l Smart Power Supply Thermal Rollback activating at 85°C.
l A fail-safe thermal protection circuit activating at 95°C.
Your amplifier also incorporates an innovative Fault Diagnosis system that
identifies a blown power supply fuse.
NOTE: If you experience blown main power supply fuses.
Do
NOT increase
values beyond the original fuse value! Doing so
wi//
void your warranty and
may damage your
amplifier.
