Dynacord L2800FD Description
The Dynacord L2800FD combines powerful two-channel amplification with integrated digital speaker processing in a rugged 2U rackmount chassis. Its connectivity, cooling system, and controls are optimized for live and mobile applications, making it well suited for touring systems, rental companies, event production, installed PA systems, and high-output portable sound rigs.
The Class H output stage delivers up to 2200W per channel at 2 ohms, 1300W per channel at 4 ohms, or 4400W in bridged mode at 4 ohms. A frequency response of 10Hz to 21kHz and a signal-to-noise ratio greater than 107dB support clean, detailed audio reproduction across demanding full-range and subwoofer applications.
Integrated DSP provides FIR filtering, audio limiting, load-impedance monitoring, equalization, and delay functions. With firmware 2.0, the amplifier supports SONICUE sound system software, output and array delay, a 10-band user parametric EQ, and a five-band array parametric EQ for each channel.
A front-panel LC display allows direct control and supervision without requiring an external computer. Built-in protection against excessive temperature, DC, high-frequency signals, Back-EMF, peak current, and inrush current helps maintain reliable operation in professional environments.
