Pragmatic Develops Powerful And Efficient In-Wall Amplifier

August 30, 2007

Pragmatic Communication Systems, Inc. recently announced the SIWA-248 stereo in-wall amplifier with 48 watts. The SIWA is another advancement in Pragmatic’s HideAway™ series of audio components, which offers the most compact and efficient designs. The SIWA-248 houses two separate mono-block amplifiers that provide extremely clean state-of-the-art power and produce unexpected sound depth and musical clarity. The SIWA-248 accepts any volume controlled line level stereo input and uses super quiet 15 V DC power. Advanced protection circuitry guards against system damage from overload, overheating, or short circuits. The amplifier is available in 3 different configurations and fits inside a single gang. One of its configurations comes with pre-amp level signals and DC power inputs in the front with a speaker wire connection in the rear. Another configuration has only a DC power input in the front with the pre-amp level input signals and speaker wire connections in the rear. The last option is a unit with a blank access panel in the front and all the connections for DC power, pre-amp level input signals and speaker wire connections in the rear. Pragmatic develops high quality digital amplifiers that possess numerous advantages over the competition. A Pragmatic amplifier boasts high efficiency and clock frequency. It also has very linear gain and phase characteristics. The amplifier has a flat frequency response from 10 Hz to 50 kHz. There is no ripple in the pass band and very low change in distortion versus out power levels (usually between 0.01 and 0.05%). It maintains very low and uniform distortion on all frequencies and a very high signal-to-noise ratio and dynamic range.
