Audio Production Equipment : Amplifiers (Audio) : Meridian Audio Ltd - Reference 857

2-Channel Power Amplifier

Model: Reference 857

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.
