OFFLINE Dynacord SL 1800 2 x 900W Power Amp

Full Description

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.
