The Meridian 857 is a Reference Two-Channel Power Amplifier delivering 500W per channel into 4ohms. This Hi-Res Audio amplifier, bridgeable to >1.5KW, is available as a dedicated rack-mount variant and incorporates a totally new design based upon extensive research. Tremendously powerful with an incredibly low noise floor, the Meridian 857 represents a step change in amplifier design.
- STEREO OR MONOBLOC - In 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 PERFORMANCE - Low-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 THROUGHOUT - The 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 CONSTRUCTION - Non-ferrous chassis and panels – aluminium construction for magnetic linearity. Transformer including five secondary windings for maximum isolation between low-power and high-power circuitry.
- ERROR CORRECTION AND LINEARITY - The 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.
- DUAL BINDING-POSTS - Both channels feature two pairs of binding-posts on their outputs to facilitate bi-wiring of loudspeakers with two sets of connection terminals.
