The Dynacord L2800FD L-Series FIR-Drive Power Amplifier is a 2800W audio amplifier designed for performing musicians and production companies providing sound reinforcement for live performances in venues including music clubs, community hall events, performance centers, and sports venues. The L2800FD is equipped with a robust power supply and a powerful linear amp design, well suited for the most demanding environments. The sophisticated protection circuitry ensures safe, reliable operation under all conditions.
The L2800FD features SpeakOn connectors for convenient wiring to professional speakers. The amplifier utilizes high-quality components throughout for truly professional processing power and performance characteristics. The on-board DSP includes multi-band PEQs (parametric EQ), crossovers, limiters, and delay per channel. It also has true channel grouping control with extra DSP capabilities like PEQ, GEQ (graphic equalizer), and delay for each group. The Dynacord L2800FD ships with a power cord and USB cable.
