INSTALLATION AND MOUNTING
1. AMPLIFIER LOCATION
The REFERENCE amplifiers employ highly efficient circuitry and a unique
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
is securely mounted to the
vehicle. The mounting location should be either in the passenger
compartment or in the trunk 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.
Set High Power/High Current and Coherent
Mono switches to the appropriate positions (see page 11).
3. MOUNTING THE
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.
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.
Connect the fuse or circuit breaker to the battery. Leave the circuit
breaker off or the fuse out until is bolted down.
d. Secure the ground cable to a solid chassis ground on the vehicle. It may
be
to sand paint down to raw metal for a good connection.
Double check each and every connection!
f. Reconnect the fuse or circuit breaker.
5. UP
Power up the system and look at the green and red depending the
configuration, one should be lit. There may be a 2 3 the
time the the source unit is turned on to the time that the LED 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 ground lead
to amplifier for lime. This is caused by rushing info the amplifier

LEVEL SETTING
The input levels are adjusted by means of the input level controls located on the
front of
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 output the same time. The reason
is because an amplifier will only make what comes 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.
Turn the amp’s input levels to minimum position (fully counter-clockwise).
2. Set source unit volume to approximately 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 high may in hearing loss. Even
new REFERENCE amplifier sounds better than you’ve
ever heard, exercise hearing damage.
PROTECTION
REFERENCE amplifier is protected against both overheating and short
circuits by means of the following circuits:
l Main power supply
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:
you experience blown main power supply fuses. NOT increase
values beyond the original fuse value! Doing so void your warranty and
may damage your amplifier.
