Dynacord SL 1800 - 2-channel 1800W power amplifier

Dynacord SL 1800 – 2-Channel 1800W Power Amplifier

The Dynacord SL 1800 power amplifier combines power and reliability in a professional 2-channel Class H design. Designed for live sound reinforcement and installed systems, it offers an extended response of 10 Hz to 40 kHz (±1 dB) and 32 dB of gain for clear, dynamic reproduction. The front panel features gain control and LED indicators for output level, limiter, protection, and power for immediate monitoring.
