Sonics 600X (Bryston 4B) Hi-Fidelity IMAX Amplifier TESTED BUT CHANNEL A IS WEAKER AND THERE ARE ALMOST NO LOW FREQUENCIESSOLD AS-IS FOR PARTS/REPAIRNO RETURNS Sonics 600X (Bryston 4B) Overview: Sonics was the American company that supplied the audio systems for the IMAX & OMNIMAX Theaters. Their amplifiers were built by the renowned Bryston in Ontario Canada and Sonics added their front & rear panels along with input circuitry. Over the years these amps have found their way into the consumer/used market and audiophiles jump at the opportunity to own one of these legendary amplifiers. The Sonics 600X is almost identical to a Bryston 4B - they were basically rebadged with Sonics front/back plates with slightly modified circuitry for their use with IMAX systems. The Sonics 600X is a three channel power amplifier with VHF/HF/LF crossover. It is rated at 120 watts/channel RMS @ 8 Ohms and 200 watts/channel RMS @ 4 ohm. The two main channels can be bridged for 400w mono output @ 8 ohm. As a triple-mono amp, all three channels are in one chassis, and each channel has their own toroidal power transformer and power supply capacitors. The Plitron tranformers were custom-made for Bryston (82 VCT @ 2.75A, or 225 watts). The power caps for each channel consist of two 10,000µ, 63V capacitors. The rail is ± 55 V and each channel has 30.5 Joules of power supply energy storage. The back panel has a detachable grounded (three-prong) power receptacle, (1) XLR female input, XLR male looping output for LF/subwoofer, and (4) post/banana jacks for +/- on each of the two main channels. !
