INSTALLATION CONSIDERATIONS

• Installation requires appropriate tools and

safety equipment. Professional installation

is recommended.

• This product is water-resistant.

Do not submerge or subject to

high-pressure water spray.

• Before installation, turn off the audio

system and disconnect the battery

system from the audio system.

• When possible, install in a dry, well-ventilated

location that does not interfere with factory-

installed systems. If a dry environment

is not available, a location that is not

exposed to heavy splashing may be used.

• Do not install in the engine compartment,

any areas of extreme heat or where it will

be directly exposed to the elements.

• Before cutting or drilling, check for potential

obstacles behind mounting surfaces.

• Carefully route all system wiring away moving

parts and sharp edges; secure with cable ties

or wire clamps and use grommets and loom

where appropriate to protect from sharp edges.

SAFETY CONSIDERATIONS

• Only use this product with 12 volt, negative-

ground electrical systems. This product is

not certified or approved for use in aircraft.

• Mount this product securely to prevent

damage or injury in severe conditions.

• An appropriate fuse (or circuit breaker) at

the main power wire is vital for vehicle/vessel

safety and must be installed within 18 inches

(45 cm) of the positive battery connection.

• For ABYC and NMEA applications,

circuit protection is required within 7

inches (18 cm) of the battery, unless the

cable is in an enclosure or conduit.

• Listen to your audio system at

levels appropriate for operating

conditions and hearing safety.

APPENDIX A:

Input Sensitivity Level Setting

Follow the steps below to adjust the input sensitivity of each amplifier

channel pair to achieve overall system balance.

Necessary Equipment

• Digital AC Voltmeter

• Sine-wave test tone recorded at 0 dBfs reference level in the frequency range to be amplied.

Do not use attenuated test tones (-10 dB, -20 dB, etc.).

Full range channel/amplier applications: 1 kHz

Subwoofer channel/amplier applications: 50 Hz

• Depending on your type of source unit, the sine-wave may be played via a CD, USB thumb drive, portable media player or

Bluetooth® audio source. Make sure to disable any EQ/DSP modes on your portable media player during level setting.

The Nine-Step Procedure

1. Disconnect the speaker(s) from the amplier’s speaker output connectors.

2. Turn o all processing (bass/treble, loudness, EQ, etc.) on the source unit, processors (if used) and amplier.

Set the fader control to center position and the subwoofer level control to 3/4 of maximum, if used.

3. Turn the “Input Sens.” control all the way down.

4. Set the source unit volume to 3/4 of full volume. This will allow for reasonable gain overlap with moderate clipping at full volume.

5. Using the chart below, determine the target voltage for input sensitivity adjustment according to the nominal impedance of the

speaker system connected to the amplier 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 amplied) at 3/4 source unit volume.

7. Connect the AC voltmeter to the speaker output terminals of the amplier.

Make sure to test the voltage at the correct terminals (+ and –).

8. Increase the“Input Sens.” control until the target voltage is observed with the voltmeter.

9. Once you have adjusted each channel section to its maximum low-distortion output level, reconnect the speaker(s). The“Input

Sens.”controls can now be adjusted downward if the amplier requires attenuation to achieve the desired system balance.

IMPORTANT!

• Do not increase any “Input Sens.” setting for any amplier 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.

• It will be necessary to re-adjust the“Input Sens.” if any equalizer boost is activated after setting the“Input Sens.”

with this procedure. This applies to any EQ boost circuit, including source unit tone controls or EQ circuits. EQ cuts will not

require re-adjustment.
