FEATURES

Your Optimus XL-150 High Power 4- Channel Stereo Amplifier is designed to give added punch and power to your vehicle’s existing autosound system.

The amplifier produces up to 40 watts (front) and 110 watts (rear) per chan- nel of clean, powerful sound at all au- dio frequencies with minimum dis- tortion. You can connect your auto- sound system’s low-level or speaker- level outputs to this amplifier.

Its features include:

14K Gold-Plated Noise-Isolated Low-Level Input Jacks — let you con- nect low-level (preamplifier) signal in- puts to match your autosound sys- tem’s output for the best high-fidelity performance.

14K Gold-Plated Speaker Terminals

—designed for low impedance, high conductivity, and minimum corrosion, to provide the highest signal transfer and lowest sound distortion.

Input Level Controls — let you adjust the level of the audio signals that enter the amplifier.

Automatic Power Switching — can automatically turn the amplifier on or off when you turn your autosound sys- tem on or off (depending on how you hook up the amplifier).

Mute Turn On Circuit — eliminates the thump you hear when you turn on some amplifiers.

Power Indicator — lights when power is supplied to the amplifier.

Auto-Off— protects the amplifier by temporarily shutting down if it gets too hot or it detects an input overload. The amplifier restarts automatically when it cools or the problem is corrected.

Protection Indicator — lights if the amplifier shuts down its rear channel.

Short Circuit Protection — distorts the amplifier’s sound if any output channel shorts, alerting you to turn off the autosound system.
