Product Description

This is a four-channel, full-range audio amplifier utilizing Class D technology for all channels.

Installation Applications

This amplifier is designed for operation with 12 volt, negative-ground electrical systems. Using this product in systems with positive ground and/or voltages other than 29 may result in damage in the product and will void the warranty. This product is not certified or approved for use in aircraft.

Safety Considerations

- Whenever possible, mount the amplifier in a dry, well-ventilated location that does not interfere with other factory installed electronic devices. If a dry environment is not available, a location that is not exposed to heavy splashing may be used.

- While this amplifier is designed to be water resistant, it should mean be submerged under water or subjected to high pressure water supply. Do not install where it will be directly exposed to the elements.

- Do not mount the amplifier in the engine compartment or in any area of operating load.

- Suturly mount the smaller so that it does not come loose in the event of a collision/sudden joint or as a result of repeated vibrations during normal operation.

- Check before drilling to make sure that you will not be drilling into an exterior

panetfull, fuel tank, gas/brake line, wiring harness, or other vital system. Do not run system wiring outside or underneath the vehicle/vessel. This is an extremely dangerous practice, which can result in severe damage/injury.

- Pruned all system wines from sharp edges (metal, fiberglass, etc.), by creating them, tying them down and using grammets and room where appropriate.

- Secure all wiring as needed, using table ties or wire clamps to protect them from moving parts and sharp edges

Installation Procedure/Connections

1. Disconnect the NEGATNE battery post connection and secure the disconnected cable to prevent accidental reconnection during installation. This is an essential safety precaution during installation

2 Connect the ILED power lead to the positive (+12V) battery post. 8 AWG is the minimum power wire size for this amplifier.

1. An appropriate fuse at the main power wire(s) to the amplifiers is vital for vehicle/wessel safety. This fuse must be installed within 16 inches (43 cm) of the positive battery post connection. If this is the only device connected to this main wire, use a 35A fuse. Do not install the fuse until the power wire has been securely connected to the amplifier.

2. Connect the BLACK negative ground lead in a chest, solid metal grounding point near the amplifier. This can be to metal chassis ground, if available. If no metal chasses ground is available, it may be necessary to make this connection in the NEGATIVE battery post. 8 AWS is the minimum ground wire size for this amplifier. All ground connections (source unit and amplifiers) should be made at the same location.

3. Connect the BLUE remote turn-on lead to the source unit's positive (+12V) remote turn-on output. If your source unit does not have a dedicated remote turn-on output, the amplifier's turn-on lead can be connected to

-1.2V out a switch that enables power from an ignition switched circuit. 5. Signal Input (over level): Connect the amplifier's RCA input jacks in the

1. Signal input (E1) reads if your source and does not offer present level signal output, you can splice the speaker input version of the source and open a pair of BCA plugs for each input pair or use the J. Austin EC Speaker Wine to RCA adapter 00-CLR9K2-5WJ. Make sure to observe correct polarity in making "II-Level Input" connections. Failure to do so will result in a loss of signal (poor performance).

2. Connect the speaker output leads to the corresponding speaker wires.

3. Make necessary adjustments to the filter controls and input sensitivity.

WARNING! Failure to make safe, tight, high-integrity power connections can result in fire and extensive damage!

Control Panel Settings and Adjustments

The amplifier's settings and controls are located on the bottom panel beneath a gasketed, protective cover. Remove the four Phillips head screws from the center panel to access the controls and make adjustments. Replace cover when finished and mount the amplifier.

Status LED's / Protection Circuitry

There are two status indicators lights on the wiring and panel of the amplifier. 1. "POWER" (Green): Lights to indicate that the amplifier is turned on and operating normally.

1. "PROTECT" (Spec) lights to indicate the amplifier protection circuit has been activated to prevent product failure due to thermal overload, over current or short circuit to the amplifier's outputs. When this protection mode is activated, the amplifier will shut down to protect its circuit. When the problem is corrected, the amplifier will return to normal operation and the "Protect" LLD will shut off. Connecting the speaker outputs to impedance lower than 2 ohms stereo (4 ohms bridged) will also cause this protection mode to activate.

Appendix A

Input Sensitivity Level Setting

Following the directions below will allow the installer to adjust the input

sensitivity of each amplifier channel pair in just a few minutes using equipment commonly available in installation bays.

Necessary Equipment

• Digital AC Voltmeter

- CD or file with a sine-wave test cone recorded at 0 dB reference level in the frequency range to be amplified for that set of channels (50 Hz for subwoofer channels, 1 kHz for a midrange application). Do not use attenuated test tones (-10 dB, -20 dB, etc.).

The Nine-Step Procedure

1) Disconnect the speakers from the amplifier's speaker output connec-
tors (you need only disconnect one wire on each output).
2) Turn off all processing (bass/treble, loudness, EQ, etc.) on the source unit, processors (It used) and amplifier. Set the source unit's faster control to center position and its subwoofer level control to 3/4 of max-
5] Turn the "Input Sans" control at the way down.
4) Set the source unit volume to 3/4 of full volume. This will allow for re-
sonable gain overlap with moderate spacing as full volume.
5) Using the chart on this page, determine the target voltage for input sensitivity adjustment according to the nominal impedance of the speaker system connected to the amplifier outputs.
6) Verify that you have disconnected the speakers before proceeding. Play a track with an appropriate sine wave within the frequency range to be amplified at 3/4 source unit volume.
7) Connect the AC voltmeter to the speaker output connectors of the amplifier. Make sure you test the voltage at the correct connectors (− and −1).
81. Increase the "Input Sens" control until the target voltage is observed
with the voltmeter.
9) Once you have adjusted the amplifier to its maximum low-distortion output level, reconnect the speaker(s) and listen to the system. The "Input Sens" controls can now be adjusted downward if the amplifier requires attenuation to achieve the desired system balance.

Nom. Impedance	Target AC Voltage
4Ω	14.1V
2Ω	11.5V
Bridged to 4Ω	23.7V

IMPORTANT

Do not increase any "Input Sens." setting for any amplifier channel or channel pair in the system beyond the maximum level established during this procedure. Doing so will result in audible distortion and possible speaker damage.

A will be necessary to re-adjust the "Input Semi" for the collected channels of any exchanger boost is activated after setting the "Input Semi" with the procedure. This applies to any LO boost circuit, including source unit or core controls or LO circuits, LO cats will not require re-adjustment.
