Peavey Deca 1200 Amplifier Specification

The Peavey Deca 1200 Amplifier is a high-performance audio power amplifier designed for professional sound reinforcement applications. It delivers a robust output power of 600 watts per channel at 4 ohms, ensuring ample power for demanding audio environments. The amplifier employs advanced DDT™ (Distortion Detection Technique) circuitry, which provides reliable speaker protection by monitoring the audio signal and reducing distortion. The Deca 1200 features a dual-channel design with independent gain controls, allowing precise level adjustments for each channel. Its frequency response ranges from 20 Hz to 20 kHz, ensuring clear and accurate audio reproduction across the audible spectrum.

The amplifier's total harmonic distortion (THD) is less than 0.03%, maintaining audio fidelity even at high output levels. It includes a comprehensive set of input and output options, with balanced XLR and 1/4-inch TRS inputs, offering flexibility in connectivity. The output stage is equipped with Speakon and binding post connectors, facilitating secure and efficient connections to speakers. The Deca 1200's robust construction features a durable metal chassis designed to withstand the rigors of professional use.

Thermal management is efficiently handled by a variable-speed cooling fan, ensuring the amplifier operates within safe temperature ranges. The unit is equipped with protection features such as short circuit, thermal overload, and DC voltage protection, enhancing its reliability and longevity. The front panel includes LED indicators for power, signal, and DDT active status, providing at-a-glance monitoring of the amplifier's operational status. Measuring 19 inches in width and designed for standard rack mounting, the Peavey Deca 1200 Amplifier integrates seamlessly into existing audio setups, making it a versatile choice for live sound, installations, and other professional audio applications.
