Legacy American Amplifier Features

Protection LED Indicator

The protection circuitry in the amp will disable it 

if it senses an input overload, speaker short circuit, 

or thermal overload conditions. Should this occur, 

the PROTECT LED will be illuminated. At that time, 

it is important that you check to determine what 

has caused the protection circuitry to become 

activated. 

If the amp shut off because of a thermal overload, 

allow it to cool down before attempting to restart.

If the shutdown occured because of an input 

overload, or speaker short circuit, be sure to 

correct these conditions before attempting to 

restart the amp.

To reset the amp, turn the REMOTE power off and 

on again.

Power LED Indicator

This LED is illuminated when the REMOTE ON 

system is turned on.

11

This unit is provided with gold-plated RCA input 

jacks. Using RCA-RCA type patch cords, 

connect these inputs to the RCA outputs from 

your head unit.

Low Level Input (High Impedance)

10

High Level Input (Low Impedance)

Use these if your car stereo does not have

RCA output jacks: connect the speaker output 

from the head unit to these inputs

9

Permits you to adjust the crossover frequency 

from 80 Hz to 2.5 kHz to suit the tweeters

High Pass Control

8

Permits you to adjust the crossover frequency 

from 35 Hz to 400 Hz to suit the subwoofers

Low Pass Control

7

Allows you to increase the bass signal level sent 

to the speakers

Bass Boost Control

6

In a full range system, set this to FULL. If the amp 

is being used to power a crossover system, set to 

either HPF or LPF as needed.

Crossover Mode Switch

5

Input Level Control

Use this control to match the output of the head 

unit to the amplifier. If distortion is present, reduce 

the setting of this control.

Protects the amplifier as well as the automobile 

electrical system from short circuit conditions.

Fuse

2

These terminals are 14K Gold plated for high 

conductivity and minimum impedance loss. The 

terminals face upwards for easy wiring in tight 

situations.
