• 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.

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 ACVoltmeter
• Sine-wave test tone recorded at 0 clefs reference level in the frequency range to be ampl ified. Do not use attenuated test tones (-10 dB, -20 dB, etc.). Full range channel/amplifier applications:1 kHz Subwoofer channel/amplifier applications: SO It
• 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 amplifier’s speaker output connectors.

2. Tum off all processing (bass/treble, loudness, EQ etc) on the source unit, processes Of used)and amplifier. Set the fader control to center position and the subwoofer level control to 3/4 of maximum, if used.

3. Turn all Input Sens: controls 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 dipping 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 amplifier outputs.

6. Verify that you have disconnected the speakers before proceeding Playa 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 terminals of the amplifier. If the channel pair is operating in stereo, it is only necessary to measure one channel.
   If bridged, make sure you test the voltage at the correct terminals (Li. and R-).

8. Increase thelnput Sens.” control until the target voltage Is observed with the voltmeter.

9. Once you have adjusted each channel section to its maximum low.distation output level, reconnect the speaker(s).

10. Ihelnput Sens:controls can now be adjusted downward If the amplifier requires attenuation to achieve the desired system balance.

IMPORTANT!

• Do not increaseany ‘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 inaudible 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 drcuit, inducing source unit tone controls or EQ circuits. EQ cuts will not require re-adjustment.
