C1800FDi DSP power amplifier, install

A 2-channel install DSP power amplifier rated 2 x 900 W, with integrated FIR Drive speaker processing, controlled in SONICUE, Euroblock connections.

Step up the power without giving up control. The C1800FDi brings a 2 x 950 W Class-AB output stage and the same install-grade DSP — FIR filters, per-channel EQ, output delay, and load-impedance monitoring — to rooms that need more reach. Direct-drive 70 V/100 V feeds distributed lines straight, and a deep protection suite covers temperature, DC, HF, back-EMF, and inrush. Larger retail, hospitality, and worship spaces get clean, tuned coverage from a 2 RU box that runs front-to-rear cool.

Features

The install version of the L platform. The C1800FDi delivers 2 x 900 W into 4 ohm with fully integrated FIR Drive, sets up and supervises in SONICUE (USB), connects on Euroblock with GPIO for remote power and preset control. It drives 70 V direct drive and low-impedance loads. Three-stage front-to-rear fans and a full protection suite keep it running in the rack. Two rack units. Retail, hospitality, corporate, houses of worship, and fixed installs that want touring-grade processing built in.
