Each channel is powered by an independent power supply with high efficiency toroidal transformer. This model can be configured to operate in bridge mode (mono) providing up to a massive 650W RMS power to an 8 ohm load. They will provide full rated power at less than 0.1% total harmonic distortion.
The design incorporates a thermally cued fan forced cooling system. The protection circuitry employed in the design ensures the integrity of the amplifiers under overload conditions. The circuit even protects itself when a total short circuit is applied across the output terminals. The 'soft start' limiter will immediately shut down the output drive in overload or short circuit conditions, then will gradually restart when the fault condition has been removed.
Each channel includes its own recessed front mounted volume control and rear panel mounted XLR & 6.35mm phono jack balanced inputs with selectable sensitivities of 0.77V, 1.4V and 3.5V. This allows input signals from a wide variety of source equipment. Output connections are made via heavy duty binding posts or industry standard heavy duty speaker connectors.
