The Dynacord SL 1800 is a dual 900 W power amplifier for live sound. Ideal for powering compact passive speakers that operate on 900 W or less, the SL 1800 is a stable and reliable amp for mobile and installation sound alike. The SL range amplifiers offer three different impedances – 2 ohm, 4 ohm, and 8 ohm – for huge flexibility, all with different levels of power output to fit any system. The SL 1800 also boasts comprehensive protection circuitry, including dynamic limiting, to prevent overloading speakers. Dynacord’s Low-Pass Notch filtering improves the frequency response and transient response of any speakers it powers too, resulting in a clearer, punchier sound.
Clean, clear amplification. The SL 1800 is a highly efficient power amp for powering passive PA speakers with great stability to bring the very best possible sound. Portable and compact, but also well-suited to permanent installation in venues, this amplifier can adapt to any venue or sound system you need it to.
Improve your sound. The SL 1800 comes equipped with a wide-ranging set of protection circuitry and dynamic limiting to ensure power sent to speakers remains consistent and clean. Combined with Dynacord’s special Low Pass Notch filtering to improve transient response and tailor the frequency response of the speakers it drives, this amplifier will make your system sound its very best.
