Features

Class A/B MOSFET Power Amplifier: This is a Class A/B amplifier that uses MOSFET devices for its amplification stages and power supply.

High Gloss Chrome-Plated Finish: This amplifier has a high-gloss chrome-plated finish on the top and on all sides.  A pair of white cotton gloves is included with the amplifier to prevent finger-print smudges when handling and mounting the amp.

Digital Voltmeter: On the top of this amplifier is a digital voltmeter with cobalt blue illumination.  The interior circuit board illuminates as well.

Cooling Fan: There is a built-in cooling fan on the top of this amplifier, which is activated whenever the amplifier receives a signal from the remote turn-on lead. If the remote turn-on lead is connected to your radio, then the cooling fan will run whenever your radio is turned on.  The amplifier will shut down if the internal temperature reaches 158 degrees F.

Variable Subsonic Filter: A subsonic (infrasonic) filter allows you to filter out extremely low bass frequencies that may rob power from frequencies that the system can reproduce without distortion. Use of the infrasonic filter allows better amplifier efficiency and better audible sound.  The subsonic filter in this amplifier is continuously variable from 20Hz to 50Hz.

Soft-Start Circuitry: The amplifier automatically turns on a few seconds after you turn your vehicle's ignition switch to ACC or ON.  The power indicator on the side of the amplifier lights when the amplifier is on.

Terminals: The amp has nickel-plated, heavy-duty set screw terminals.

Protection Circuitry:

• Thermal: shuts off the amp when the operating temperature is too high
• Input Overload: shuts off the amp as a result of low voltage or over-voltage
• Short Circuit: shuts off the amp due to speaker or DC short

Controls

Left Side of Amplifier

• Front and Rear Variable Gain Controls: these rotary controls allow you to match the input sensitivity of the amp to the particular source unit you are using
• Front and Rear Subsonic Frequency Controls: these rotary controls allow you to filter out unwanted bass frequencies. The subsonic filter in this amplifier is continuously variable from 20Hz to 50Hz.
• Front and Rear High-pass Frequency Control: these rotary controls allow you to adjust the frequency of the high-pass crossover from 50Hz to 750Hz
• Front and Rear Low-pass Frequency Control: these rotary controls allow you to adjust the frequency of the low-pass crossover from 50Hz to 120Hz
• Front and Rear Crossover Switch: lets you select high-pass, low-pass or full-range operation for the speaker outputs
• Front and Rear Bass Boost Switch: lets you select either OFF or +18dB, centered at 45Hz
• Front and Rear Subsonic Frequency Switch: lets you turn the subsonic filter on or off

Inputs and Outputs

Right Side of the Amplifier

• Line-In: two sets of left and right RCA input jacks
• Line-Out: RCA preamp output jacks, which allow you pass full-range signals from this amplifier to another amp in a daisy-chain configuration.
• Speaker Terminals: four +/- pairs of nickel-plated set screw terminals (each terminal is 0.25" wide)
• BATT (power): nickel-plated set screw terminal (accepts 4-gauge wire)
• GND (ground): nickel-plated set screw terminal (accepts 4-gauge wire)
• REM (remote turn-on): nickel-plated set screw terminal (terminal is 0.31" wide)
• Fuses: two 20-amp fuses
