Solid DYNACORD technology for fixed installations at very competitive prices.
DSA power amplifiers offer a very high, stable output with high efficiency at a high performance level and are therefore the ideal choice for typical fixed installation applications. The connectivity consequently provides Phoenix type in/outs, the input level controls are located on the rear panel, also a switchable high-pass filter (50 Hz, 18 dB/oct) and a Ground Lift switch.
The POWER REMOTE connector makes the task of remote controlling the power amplifier as well as switching it on and off simple. For further remote-supervision and –control possibilities and integration into IRIS-Net networks, an optional remote control module (RCM-810) is available.

channel@2ohms these amps save valuable rack space without compromising power output. HIGH CURRENT TOROIDAL TRANSFORMER A high-current toroidal transformer saves rack space and minimizes hum and noise. EXCELLENT SOUND QUALITY The low T.H.D.(0.05%) and high damping factor (400 or higher) gives excellent sound quality. 2 STAGE POWER SUPPLY The high-power units (L1800 and L2400) have a 2-Stage Class-H design that maximizes their performance. EQUIPPED WITH 30Hz or 50Hz HPF All amplifiers are equipped with high-pass filters on each channel to help maintain sound quality, yet help protect the loudspeakers. EXTENSIVE PROTECTION CIRCUITS Extensive protection circuits monitor over voltage/current conditions, overheating, output shorts, and DC voltage to improve performance and reliability. CLIP-LIMITER CIRCUITS Clip-limiters on each channel are provided to help prevent distortion due to excessive signal levels. L.E.D FUNCTION DISPLAYS Power, Clip limiter, Signal, Protection, Mode (Parallel/Stereo/Bridged) LEDs on the front panel indicate the status of the unit in operation.

Solid DYNACORD amplifier technology at highly competitive prices.
These amplifiers offer high, stable power output and a high efficiency factor on the high performance level and are therefore the ideal choice for driving a multitude of mobile and club systems. SL series power amplifiers are equipped with a comprehensive protection package and dynamic limiters.
The integrated, switchable Low-Pass Notch filter (a typical DYNACORD special feature) corrects the frequency response and optimizes the transient behaviour of loudspeakers.
