The Dynacord L1800FD Amplifier is a two-channel live-sound power amplifier with fully integrated DSP, and the Dynacord L1800FD Amplifier delivers 2 x 950 W at 4 ohms in single-channel terms, with 2 x 850 W per channel with both channels driven. FIR Drive speaker processing, parametric and graphic equalisation, delay and limiting all live inside the amplifier, so a touring rig or an installed system can be tuned without a separate loudspeaker processor in the rack.
Why Choose Dynacord L1800FD Amplifier?
Power amplifiers are often bought on watts alone, and the Dynacord L1800FD Amplifier is built to be judged on control as well. The Class AB output stage is stable down to 2 ohms, and bridged operation gives 2800 W into 4 ohms for a single large subwoofer or a long-throw cabinet. SONICUE software configures and supervises the amplifier over USB, with system presets and offline editing, while the front-panel display allows local monitoring, and a full protection suite guards against temperature, DC, high-frequency, back-EMF and short-circuit faults.
Key Features
2 x 950 W at 4 ohms: Single-channel maximum output; 850 W per channel with both channels driven, 450 W per channel at 8 ohms.
FIR Drive processing: FIR filters, parametric and 31-band graphic EQ per channel, delay and limiters on board.
SONICUE control: Full configuration and supervision from Dynacord’s system software over USB.
True 2-ohm stability: Drives low-impedance loads and bridges to 2800 W into 4 ohms.
Class AB output stage: Linear amplifier design with a robust power supply for demanding live use.
Full protection suite: Audio limiters plus temperature, DC, HF, back-EMF, peak-current and inrush protection, with 3-stage front-to-rear fans.
Best Suited For
The Dynacord L1800FD Amplifier suits live production companies, clubs, theatres and houses of worship running passive loudspeakers that need both power and on-board tuning. It is a 2U rack amplifier for installed or touring racks, not a mixer or a powered speaker, and it expects a mixer or processor in front of it and passive cabinets behind it.
Setup and Connection Guide
Rack the Dynacord L1800FD Amplifier with clear front-to-rear airflow, connect the mixer outputs to the two XLR inputs, and connect passive loudspeakers to the speakON outputs, checking that each channel’s load impedance is within the amplifier’s ratings. Use SONICUE over USB to load or build a preset with the correct FIR filters, EQ and delay for the loudspeakers in use, set the limiters to protect the drivers, and verify levels on the front-panel display before the show. Keep bridged mode for a single cabinet only, and never bridge into a load below the rated impedance.
Frequently Asked Questions
How much power does it really deliver?
With both channels driven, the Dynacord L1800FD Amplifier delivers 850 W per channel at 4 ohms and 450 W at 8 ohms. The 950 W figure is the single-channel maximum at 4 ohms, and bridged output is 2800 W into 4 ohms.
Do I still need a separate loudspeaker processor?
In most cases no. FIR Drive, PEQ, 31-band GEQ, delay and limiters are built in and configured in SONICUE, which replaces a separate processor for standard two-channel rigs.
Can it drive 2-ohm loads?
Yes. The L1800FD is stable down to 2 ohms, delivering up to 1400 W per channel with both channels driven at 2 ohms.
