your radio/source unit requires a reset code. Check the

operation manual for your vehicle or contact the dealer.

Setup

Quick Start

Installation Guide

The illustrations below describe the various controls. Refer to

the illustration that matches your amplier.

The gain control purpose is to match

the output of your source signal to the

amplier. Refer to the section B below for

detailed instructions.

This switch will set the amplier to have a

full frequency output or to lter out high or

low frequencies. The NA1-400.2RC offers

either a bandpass or a high pass lter.

The Boost Switch will increase the signal

12dB at 45Hz. Be aware this setting can

cause distortion if the gain is not set

properly.

1. If possible, with the source unit off, conrm that the primary volume control is

turned down (counter clockwise).

2. Turn on the source unit (CD, or MP3 player). Re-conrm that the volume is

turned down. Make sure the source unit controls; balance, fader, bass and

treble are all set to center or “0” adjustment. Make sure that the green LED on

the end of the amplier is illuminated.

3. Play a clean musical selection of which you are very familiar. CD is preferred.

Do not use radio signals for level setting. Hit play and start turning the volume

of the source unit up.

4. Stop increasing the source unit volume when you reach 3/4 (about 75%) or until

you hear speakers begin to slightly start producing distortion.

5. Increase the amplier gain (clockwise) until distortion is heard, then back

the level down (counter clockwise) until the distortion is eliminated. Small

adjustments may need to be made to balance the levels of multiple ampliers.

Settings

This is a critical step to insure your amplier

is properly adjusted to match the signal

output level of your source unit.

THIS IS NOT A VOLUME CONTROL!
