Dynacord L1800FD - 2-Channel DSP Power Amplifier with FIR Drive 1700W

Dynacord L1800FD – 2-Channel DSP Power Amplifier with FIR Drive

The Dynacord L1800FD is a professional 2-channel unit that integrates digital processing (DSP) with FIR Drive technology, offering FIR filters, a limiter, delay, graphic equalization (GEQ), and parametric equalization (PEQ) per channel. Its Class H topology (previously referred to as Enhanced AB) combines efficiency and power, ensuring stability even into demanding 2 Ω loads. Designed for live and installed applications, it features a front-facing LCD display and LEDs indicating level, limiter, protection, and power for immediate monitoring.

Main features

• Connectors: Balanced 3-pin XLR inputs and outputs; NL4 Speakon outputs.
• Protections: Overload, overtemperature, short circuit, back EMF, current spikes, HF and DC output, inrush and soft-start.
• Rack format: 19″ × 2 U; dimensions: 483 × 88 × 462.4 mm; weight: 15.2 kg.

Product benefits

• Robust design: Metal chassis and optimized ventilation for continuous use.
• Advanced control: DSP and SONICUE software for fine-tuning and remote management.
• High efficiency: Class H minimizes consumption and generates less heat.
• Direct monitoring: LED/LCD panel and status LEDs for immediate diagnosis.
• Versatility: Ideal for touring, concerts, fixed installations and corporate AV systems.

Use cases

• Sound reinforcement for musical tours, festivals, and live events.
• Fixed installations in auditoriums, theaters, convention centers and conference rooms.
• Integrated PA and AV systems for educational and corporate environments.
• Sound reinforcement for stadiums and sports venues.

Frequently Asked Questions

• Does it require additional software? For advanced presets and adjustments, we recommend SONICUE with firmware v2.x or higher.
• How is it ventilated? Front-to-rear flow with three-speed fans depending on the load.
• Can it work in low impedance? Yes, stable down to 2 Ω in stereo mode.
• Is it suitable for outdoor use? The finish is durable, but it should be protected from direct rain.
