Dynacord C1800FDi Description

The Dynacord C1800FDi is engineered for installed audio systems in bars, restaurants, houses of worship, sports facilities, performing arts centers, and other venues that need reliable amplification with professional loudspeaker processing. Its robust power supply and Class-AB amplifier topology provide stable performance for demanding permanent installation environments.

In dual-channel operation, the amplifier delivers 2 x 1400W at 2 ohms, 2 x 850W at 4 ohms, and 2 x 450W at 8 ohms. It also supports bridged operation and high-impedance 70V and 100V systems, making it suitable for both direct low-Z loudspeaker systems and distributed audio lines.

Onboard DSP gives installers the tools needed to tune and protect the system. Processing includes FIR filters, audio limiters, output delay per channel, PEQ per channel, 31-band GEQ per channel, and load impedance monitoring. FIR-Drive technology helps optimize loudspeaker settings for accurate system performance.

The Dynacord C1800FDi also includes Euroblock connectors, remote power-on delay, GPIO control support, standby power mode, and software-based configuration and monitoring. Its protection system covers high temperature, DC, HF, back-EMF, peak current, inrush current, and turn-on delay conditions for reliable operation.
