FEATURES

Your Optimus 85 × 4 High Power 4- Channel Trunk Mount Amplifier is de- signed to produce a total of 340 watts to give added punch and power to your vehicle’s existing stereo sys- tem.

The amplifier produces up to 85 watts per channel of clean, powerful sound at all audio frequencies with minimum distortion. You can adjust the crossover frequency for both channels 3 and 4 when using only two speakers and a subwoofer, so you can emphasize the bass sounds but not lose the other sounds or pow- er. You can connect your autosound system’s line-level or speaker level outputs to the amplifier.

Its features include:

14k Gold-Plated Noise-Isolated

Line-Level Input Jacks - let you connect low-level(pre-amplifier) sig- nal inputs to match your autosound system’s output for the best high-fi- delity performance.

14k Gold-Plated Speaker Termi-

nals - designed for low impedance, high conductivity, and minimum cor- rosion to provide the highest signal transfer and lowest sound distortion.

Input Level Controls - let you adjust

the level of the audio signals that en- ter the amplifier.

Automatic Power Switching - auto-

matically turns on/off the amplifier when you turn on/off your autosound system.

Bridging Capability - lets you com- bine the amplifier’s four 85-watt channels so you can use the system with only two channels that produce a total of 170 watts from each chan- nel.

Crossover Frequency Circuit - lets

you adjust the crossover frequency from 45-400 Hz for both channels three and four when you use only two speakers.

Crossover Frequency ON/OFF

Switch - lets you set the amplifier to drive a connected subwoofer.

Automatic Thermal Protection

System (ATPS) - automatically low- ers the amplifier’s output power when the amplifier’s internal temper- ature reaches 202× F then increases the output power when the amplifier cools down.
