Low Noise Preamplifier Circuit

Maximum low voltage signal from the source unit comes into the amplifier through a low voltage circuit which delivers minimal distortion through the amplification process.

RCA Inputs

Low voltage RCA Inputs: Highest sound quality connection with quality RCA materials helps prevent interference and minimize distortion in the signal path.

High Level Inputs

Easily tie into OEM audio systems that do not offer RCA output to maximize aftermarket amplifier power.

Operation Mode

Four Channel Stereo, Dual Stereo Bridged, Stereo + Bridged Mono, Dual Bridged Mono

Crossover Type

Fully Adjustable 12dB Crossovers

Electronic Equalizer

Control of amplifier output with on board electronic crossover to tailor specific frequencies to speakers and subwoofers.

Class / Topology

High sound quality circuit that allows POWER DRIVE to develop high levels of power with minimal distortion.

Output Device Technology

Exclusive Crunch SPEED-FET MOSFET components maximize power efficiency while improving sound quality and minimizing distortion.

Heat Sink

Quick Thermal Dispersion Technology assures additional mass in the aluminum heat sink keeps the amplifier running cool with nearly undetectable distortions during normal music listening.

Power Supply

High energy Pulse Width Modulated Power Supply delivers power with minimal impact on the electrical system.

Output Connections

Nickel Plated Brass Connection with terminals allow for secure connection while resisting corrosion.

Connection Type

Screw Down Connectors: Easy access for hand tool allowing a quick and secure connection.

LED System Protection Circuitry Diagnostics

Monitor overload and speaker short protection with lighted indicators on the amplifier end panel.
