Meridian's most powerful reference two channel amplifier has been designed and built to deliver the best possible Hi-Res audio performance from any high-quality passive loudspeaker system. Its low-feedback construction provides ultra-low distortion, ensuring an unparalleled level of clarity and transparency across the audible range. Bridgeable to over 1.5Kw, the Meridian 857 features a totally new design for a Meridian power amplifier, borne out of extensive research, experience and a thorough understanding of psychoacoustic principles. FEATURESEffortless power delivery of 500W per channel into four ohms and bridgeable to 1.5kW mono into 4.1-1000kHz frequency response -/+ 2dB - Perfect for high res audioFan assisted cooling operating at elevated temperatures enabling silent operation in room and rack installationsLow feedback construction provides ultra-low distortion, ensuring an unparalleled level of clarity and transparency across the audible range. STEREO OR MONOBLOCIn normal mode, delivers 2 x 250 watts into 8 ohms and 500 watts into 4 ohms; continuously on both channels. In bridged mode, delivers 1 x 1 kilowatt into 8 ohms and 1 x 1.5 kilowatts into 4 ohms. REFERENCE PERFORMANCELow-feedback construction provides ultra-low distortion, ensuring an unparalleled level of clarity and transparency across its full frequency response of 1-100kHz (-/+ 2dB). BALANCED DESIGN THROUGHOUTThe signal path is balanced throughout - fed from either the XLR balanced inputs or from the SuperBal circuitry which converts unbalanced (single-ended) signals to balanced audio as soon as they enter the amplifier. EXTREME CONSTRUCTIONNon-ferrous chassis and panelsaluminium construction for magnetic linearity. Transformer including five secondary windings for maximum isolation between low-power and high-power circuitry. Ground plane design with multilayer circuit boards optimised for signal handling. ERROR CORRECTION AND LINEARITYThe open-loop characteristics of an amplifier are crucial to its sound quality. The power amplifier design is intrinsically linear and uses error correction in the output stage to provide low open-loop output impedance. This allows the power amplifier to achieve impeccable measured performance and a high damping factor while only applying modest amounts of negative feedback. DUAL BINDING-POSTSBoth channels feature two pairs of binding-posts on their outputs to facilitate bi-wiring of loudspeakers with two sets of connection terminals.
