Features

Class A 100% Discrete Driver Circuitry Topology: The preamp stages use Class A topology for low distortion and a high damping factor; the result is tight, controlled bass.

Pure N-Channel Design: The pure N-channel design is more linear than typical N-Channel designs, so the speaker you connect to the amplifier will be better controlled. The signal travels through fewer parts so the signal-to-noise ratio is enhanced, the power rating is better, and the amp runs louder, longer.

Smart-Engage™: When using the speaker-level input, the amp automatically turns on when it senses signal from the head unit, eliminating the need for a remote turn-on connection. In many cases, this feature will allow you to install the amplifier without the need to remove your radio.

Internal Crossovers: There is one crossover for the front channels and another for the rear channels. The crossover for the front channels may be set for 85Hz, 18dB/octave high-pass operation, or it may be turned off for full-range operation. The crossover for the rear channels may be set for 85Hz, 18dB/octave high- or low-pass operation, or it may be turned off for full-range operation.

Buffered, Isolated RCA Output: In addition to the front and rear sets of preamp inputs, there is a set of full-range summed RCA preamp outputs. The outputs allow you to daisy-chain one amplifier to another.

Intelligent Surface Mount Technology: Features substantially shorter internal and external lead lengths, reducing stray capacitance and inductance, which results in cleaner and more accurate musical reproduction with less noise interference.

Real-time Computerized Protection Circuit: The protection circuit makes sure you amp is operating within safe parameters for maximum power and protection.

Acoustically Seamless Turn-on/Turn-off: A circuit that prevents turn-on/turn-off "thump" is included to eliminate turn-on/off noise.

Iso-Feet™: Four rubber Iso-Feet are attached to the amplifier. The rubber feet let you mount the amp securely, while preventing the mounting screws from coming into contact with the amp's chassis; this helps prevent ground loops.

Terminals: The terminals are nickel-plated, heavy-duty screw terminal connectors.

Performance Certificate: MTX tests each amplifier, and the technician records the "actual" power output on the Certified Performance Certificate included with each amp. The amp must meet or exceed the rated specification in order to leave the factory.

Inputs, Outputs and Controls

Left Side of the Amplifier

• Front and Rear Variable Gain Controls: the gain controls allow you match the input sensitivity of the amp to the particular source unit you are using
• RCA Input Select Switch: a switch used to match the amp's input to the source unit's output so all four channels of the amp are driven. If your source unit has 2 outputs (a left and a right), connect them to the amp's front channel inputs, and place the input select switch in the 2CH position. Likewise, if you are using a 4-channel source, place the input select switch in the 4CH position. In the 4CH position, the fader on your source unit will operate.
• Front left and right RCA input jacks
• Rear left and right RCA input jacks
• RCA Sum Out Jacks: RCA preamp output jacks, which allow you pass summed, full-range signals from this amplifier to another amp in a daisy-chain configuration
• Front Crossover Switch: lets you select high pass or full range operation
• Rear Crossover Switch: lets you select high pass, low pass, or full range operation
• Front and Rear Speaker Level Inputs: two 4-pin inputs for use with the included speaker-level input harnesses; allow the amp to operate with source units that do not have preamp outputs

Right Side of the Amplifier

• Speaker Outputs: these terminals are configured like steps, with the rear left and right outputs in a row below the front left and right outputs (0.34" wide)
• BATT (power): screw terminal (terminal is 0.54" wide)
• GND (ground): screw terminal (terminal is 0.54" wide)
• REM (remote turn-on): screw terminal (terminal is 0.34" wide)
• Fuses: slots for two 25-amp blade fuses (fuses are included)
