		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.

5.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:

•Main power supply luses * Circuit breakers

•Smart Power Supply Thermal Rollback activating at 85°C.

•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.
