Peavey MA 212 Amplifier Specification

The Peavey MA 212 Amplifier is a robust audio power amplifier designed for professional sound reinforcement applications, delivering reliable performance with high efficiency. It features a dual-channel configuration, providing two independent 120-watt outputs, which can be bridged to deliver a single 240-watt output for more demanding audio setups. This amplifier is engineered with a solid-state design, ensuring consistent audio fidelity and operational stability across various environments.

The amplifier's input section supports both balanced and unbalanced connections, accommodating a wide range of audio sources and system configurations. Advanced thermal management is integrated, utilizing a variable-speed fan to maintain optimal operating temperatures and protect against overheating, thereby enhancing longevity and reliability.

Peavey's proprietary DDT (Distortion Detection Technique) circuitry is employed to prevent clipping, ensuring clean audio output even at high power levels. This feature is crucial for maintaining sound integrity and preventing potential damage to connected speakers. The MA 212 is housed in a rugged, rack-mountable chassis designed for easy integration into standard 19-inch equipment racks, making it suitable for both permanent installations and mobile setups.

Front-panel indicators provide real-time status updates, including power, signal presence, and DDT activation, allowing for quick diagnostics and monitoring during operation. The amplifier's robust construction and comprehensive protection features, including short circuit, thermal, and DC voltage protection, underscore its suitability for demanding professional audio applications. The Peavey MA 212 Amplifier is ideal for venues requiring dependable and high-quality sound amplification with flexible configuration options.
