Stereo power amplifier from SX series that has been designed to provide robust, clean output with low distortion and wide dynamic range, along with the dependability demanded by professional audio engineers and installers. The convenient two rack-space design is compact, and yet there is plenty of power available, with 2 x 300 watts at 8Ω and 2 x 450 watts at 4Ω over the full frequency spectrum, from 10 Hz to 55 kHz. For mono applications, a bridged mode links both channels of the amplifiers, thus providing even more power, with a power rating of 900 watts for the amplifier into an 8 ohm load. Input connections are made via combination connectors allowing for both balanced XLR and balanced 6.3mm TRS connections. For the outputs, the amplifier provides standard 5-way binding posts, as well as Speakon connectors. Front panel controls and displays include a power switch with LED indicator, as well as independent left and right channel input level controls. To help user set the correct operating levels, the amplifier includes front panel Signal, Peak and Protection LED indicators. Like all serious power amplifiers, its internal electronics are based around a serious power core, with oversized toroidal transformer and large extruded heat sinks. To keep the amplifier running cool, itsr designs employs twin internal wind tunnels with forced-air cooling via two temperature-sensitive, variable speed fans, which greatly reduce the chance of thermal and overheating problems. Multi-stage protection for power-up, over-heating, over-current, short circuit, low output impedance and DC voltage, assures high reliability under the most demanding situations. The amplifier is road tough with its all steel chassis, 19-inch rack-mount design and convenient carry handles, so it is ready for a life of travel, or to make its home in a fixed installation.
