Meridian G57 2-Channel Power Amplifier [ex-demo]

Two-Channel

G57

The Meridian G57 is our powerful Two Channel Power Amplifier. Suitable for a variety of applications the G57 includes both balanced XLR-3F analogue inputs and unbalanced phono inputs.

The unbalanced inputs are converted to balance before they enter the amplifier itself, using Meridian’s proprietary ‘Super Balanced’ technology. The G57 combines power, clarity and flexibility for the ultimate in 2-channel amplifier performance at any volume level.

The G57 is an award winning high resolution power amplifier. Derived from the same technology we use in our flagship DSP8000 this high power, ultra-low distortion, wide bandwidth power amplifier can comfortably drive any passive loudspeaker with control, fidelity and authority.

Stereo or Monobloc

In normal mode, delivers 2 x 200 watts into 8 ohms continuously on both channels. In bridged mode, delivers 1 x >650 watts into 8 ohms or 1 x ~1000 watts into 4 ohms.

Power with Finesse

Features a capacitor-free signal path for fast, accurate bass and a unique ultra-low-feedback design for superb overall sound. Each channel delivers its audio from four pairs of high-powered output devices.

BUILT TO PERFORM AND TO LAST

The elegant aluminium, steel and glass case houses the two independent amplifier assemblies, each with its own massive internal heatsink. A huge toroidal transformer and four highly-specified reservoir capacitors ensure amazing instantaneous power is available whenever it is required.

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.

ELECTRONICALLY PROTECTED

Features full protection against thermal overload, DC on its inputs and short-circuits on its outputs.

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.

The award winning G-Series high-resolution power amplifiers integrate the same technology we used within the Special Edition range of loudspeakers.

The G55 and G57 are high-power, ultra-low distortion, wide bandwidth power amplifiers that can comfortably drive any passive loudspeaker with control, fidelity and authority.

With its extensive Research and Development programme Meridian has pioneered the development of a host of innovative audio technologies many of which feature in today’s Meridian products.
