What is it?A four-channel power amplifier designed for fixed installed sound systems.DetailsCapable of delivering 8 x 200W output into 4 ohms and 8 x 140W into 8 ohms, the SA8200’s inputs may be linked by recessed switches on the back panel of the amplifier for greater flexibility. A 50Hz high-pass filter can also be applied on each channel – for example, if used in 100V/70V line systems. The SA4200 incorporates a number of protection circuits for improved reliability including soft-start, short-circuit and overload protection plus DC and thermal protection.On the steel front cover there are LEDs for signal presence, clip and protect for each channel. The detented volume knobs are recessed to prevent accidental level changes. The amplifier may be mounted in a standard 19” rack and requires only a 3U space. All connectors on the XFormer Box are Euroblocks and the design incorporates a pair of two-speed fans. Frequency response is measured at 20Hz – 20kHz with THD (20Hz – 20kHz) at < 0.1%. Signal to noise ratio is >103dB and talkover is quoted as 60dB. And another thing…Optional 70/100 V transformers are available offering 160W power. Four of these may be mounted in special 19”, 1U black steel housing.
