Thank you for purchasing an Audiobahn A/B Power Amplifier
specifically designed for the mobile environment. This manual contains
important information about installation, set-up procedures and intergrading
this amplifier into your car stereo system. With proper care and installation,
your new audiobahn A/B Mosfet Power amplifier will provide you with
many years of high performance listening enjoyment.
Before making any electrical connections, Make sure that vou disconnect the
battery’s ground cable to prevent the possibility of short &wits or damage to
your electronic equipment. (rJ’your stereo has an Anti-th# code DO NOT
disconnect the battery).

This control adjusts the amplifiers input sensitivity. Input sensitivity is variable from 200 Millivolts
to 7 volts. Clockwise increases sensitivity Counterclockwise decreases sensitivity.
This knob is not a volume control for the amplifier. The amplifier can be driven to full power
with a wide range of signal levels. A lower signal level will require increased sensitivity for full
power. A higher signal level will require decreased sensitivity.

-PWR (Power) : This BLUELED will illuminate when the amplifier is turned “ON”. If it fails to
illuminate, check the power connections to the Amplifier and fuses.
-PROT ( Protection] : The amplifier protection circuitry will disable the amplifier if input
overload, short circuit or extremely high temperature conditions are detected. When the
protection mode is in operation, the LED indicator on the side panel will be illuminated,
indicating the amplifier has gone into a self-preservation mode.
If you observe that the Protection LED is lit, please check the system carefully to determine
what has caused the protection circuit to engage. The amplifier can be reset by turning
the remote power off and then on again. If the amplifier shut down due to a thermal
overload condition, please allow it to cool down before restarting. If the amplifier shut
down because of an input overload or short circuit, be sure to repair these conditions
before attempting to power up the amplifier again,

Planning and Mounting Your System

The mounting position of your Amplifier will have a great effect on its ability to dissipate
the heat generated during normal operation.
It has an ample heat sink for heat dissipation, and also designed with a thermal shutdown (for heat protection) circuit. DO NOT enclose the amplifier in a small box or
cover it so that air can not flow freely.
Temperatures in car trunks have been measured as high as (155’ C) in the summer time.
since the thermal shut-down point for the amplifier is (158’ C) it is easy to see that it must
be mounted for maximum cooling capability. To achieve the maximum advantage of
convection air flow in an enclosed trunk, mount the amplifier in a horizontal position.
Cooling requirements are considerably relaxed when mounting inside the passenger
compartment since the driver will not often allow temperatures to reach a critical point.
Floor mounting under the seat is usually satisfactory as long as there is at least 1 inch
of clearance (2.54 cm) above the Amplifier’s fins for ventilation.

And has ample room for air circulation and cooling.

For the best performance, you must set GAIN (MIN/MAX) on the side of the amplifier to
adjust the level of the audio signals that enter the amplifier.
1. Use a screwdriver to turn GAIN (MIN/MAX) fully counterclockwise
to MIN>
2. Turn the auto sound system’s volume control to about one-third of its full range.
3. Adjust GAIN (MIN/MAX) to a comfortable listening level.
4. Turn up the auto sound system’s volume control until the sound begins to distort. Then
immediately turn the volume down to a point just before where the distortion began.
Caution : Never turn up the auto sound system’s volume control more than needed to
adjust the audio level, more than two thirds of its maximum volume.
5. Adjust GAIN (MIN/MAX) until the sound is at the maximum level you want the amplifier
to produce.
6. Adjust the auto sound system’s volume control to a comfortable listening level.
