Your RadioShack High Power 4/3/2-Chan- nel Bridgeable Amplifier produces a total of 400 watts to give added punch and power to your vehicle’s existing auto sound system.

The amplifier produces up to 200 watts per channel (if bridged) of clean, powerful sound at all audio frequencies with minimum distor- tion. You can connect your auto sound sys- tem’s low-level or speaker-level outputs to this amplifier.

Its features include:

14K Gold-Plated Noise-Isolated Low-Lev-

el Input Jacks — let you connect low-level (preamplifier) signal inputs to match your auto sound system’s output for the best high- fidelity performance.

14K Gold-Plated Speaker Terminals — de- signed for low impedance, high conductivity, and minimum corrosion, to provide the high- est signal transfer and lowest sound distor- tion.

Input Level Controls — let you adjust the level of the audio signals that enter the am- plifier.

Automatic Power Switching — can auto- matically turn the amplifier on or off when you turn your auto sound system on or off (depending on how you hook up the amplifi- er).

Bridging Capability — lets you combine the amplifier’s four 100-watt channels so you can use the amplifier with only two channels that produce a total of 200 watts from each chan- nel.

Mute Turn On Circuit — eliminates the thump you hear when you turn on some am- plifiers.

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

Protection Indicator — lights if the amplifier shuts itself down.

Crossover Frequency Circuit — lets you adjust the crossover frequency from 45–400 Hz. This lets you set up the amplifier so you can connect a subwoofer.

Short Circuit Protection — distorts the am- plifier’s sound if any output channel shorts, alerting you to turn off the auto sound sys- tem.

Auto-Off— temporarily shuts down the am- plifier to protect the amplifier from overheat- ing or input overloads. The amplifier restarts automatically when it cools or the problem is corrected.

THE FCC WANTS YOU TO KNOW

Your amplifier might cause TV or radio inter- ference even when it is operating properly. To determine whether your amplifier is caus- ing the interference, turn off your amplifier. If the interference goes away, your amplifier is causing it. Try to eliminate the interference by:

•moving your amplifier away from the receiver

•contacting your local RadioShack store for help

If you cannot eliminate the interference, the FCC requires that you stop using your ampli- fier.
