Audiotek AT-2400S 2-Channel Car Amplifier

The Audiotek AT-2400S is a 2-channel, full-range car amplifier designed to add external amplification to a 12V vehicle audio system. It is rated for 2400 watts of peak output and supports both speaker and subwoofer applications. Its 2-ohm-stable design provides flexibility when matching compatible speaker loads.

This amplifier is suited to installers building a basic two-channel system, adding power to front or rear speakers, or configuring an appropriate subwoofer setup. RCA and speaker-level inputs allow it to connect with a variety of source-unit signal configurations. A remote turn-on/turn-off circuit supports integration with a vehicle audio system.

The AT-2400S uses Class A-B operation and is described as a full-range amplifier, allowing it to handle low, mid, and high-frequency program material. A continuously variable input gain control helps match the amplifier to the source signal. It also includes adjustable bass boost and a variable low-pass crossover for system tuning.

A bridgeable MOSFET amplifier design and tri-mode capability provide configuration flexibility for compatible installations. Its MOSFET pulse-width-modulated power supply is intended to support stable amplifier operation. The published 2400-watt rating is a peak-power figure; an RMS power specification is not confirmed in the available product information.

The chassis uses a heavy-duty aluminum-alloy heat sink to manage heat during operation. Thermal and speaker-short protection circuitry help safeguard the amplifier, while LED power and protection indicators provide at-a-glance operating status. A remote subwoofer control with bass knob is included for convenient bass-level adjustment.

Key Features

• Two-Channel Output: Supports stereo speaker systems or compatible subwoofer applications.
• 2-Ohm Stable Operation: Accommodates compatible low-impedance speaker loads.
• Class A-B Design: Provides full-range amplification for varied system layouts.
• Bridgeable Configuration: Adds flexibility for compatible single-channel setups.
• Remote Bass Control: Lets you adjust bass level from the included knob.
• Protection Circuitry: Includes thermal and speaker-short protection features.

Design & Installation

The AT-2400S has a surface-mount form factor with a heavy-duty aluminum-alloy heat sink. Its connection and control set includes nickel-plated RCA inputs, speaker-level inputs, LED status indicators, gain control, crossover adjustment, and bass adjustment. The amplifier also uses a soft turn-on circuit and remote turn-on/turn-off capability.

Install the amplifier securely on an appropriate surface with adequate ventilation around the heat sink. It is intended for 12V vehicle systems and can accept either RCA or speaker-level audio input. Match connected speakers and subwoofers to the amplifier's supported load requirements, and use the gain, crossover, and bass controls to integrate it with the rest of the system.
