Designed to match other G Series components, G57 features a luxurious bead blasted metal exterior with glass accents. Two channels of 200 watts of clean power provide breathtaking performance from any passive loudspeaker. Like the G55 multi-channel amplifier, G57 is based on innovations in amplifier design first introduced in Meridian’s flagship DSP8000 Loudspeaker. G57 is equally at home partnering with 800 or G Series. When combined with G55 and a Meridian Surround Controller, the G57 becomes an integral part of a 7.1 analogue theatre system.
While providing 200 watts per channel, the G57 can be bridged to provide a staggering 1,000 watts of mono power. This allows a system to grow from a single G57 in stereo, to a pair in mono for a reference level amplifier combination. Meridian’s “Super Balanced” operation internally balances even single ended signals for the best sound quality.
G57 is constructed of a bead blasted, metal chassis with glass accents that surround an additional inner chassis. This double skinned approach protects delicate signals inside the G57 to be isolated from outside noise. This is just one of the means that Meridian employs to deliver lifelike performance while keeping an eye on industrial design.
Designed for the ultimate in performance and flexibility, G57 incorporates a unique bridging circuit that reconfigures both channels into one mono channel. In this mode, two channels are combined to provide 1,000 watts of power - this makes for a simple upgrade path that allows you to start with one G57 in stereo and then add another for higher performance.
A 12-volt trigger input allows the G57 to be activated from your preamp or surround controller. This makes for simple, care free, and efficient operation. This trigger is optically isolated from the amplifier, thus eliminating any chance of noise.
For custom installations, G57 uses the same G Series Rack kit making it simple and easy to install. A separate output trigger controls intake and exhaust fans integrated into the rack kit. This ensures the fans operate when the G57 is on, keeping it at its optimal temperature.
The G57 contains two amplifier modules, featuring a symmetrical design with fully electronically balanced inputs. Meridian employs a soft start circuit that eliminates any turn on and turn off “thumps.” Both balanced and unbalanced inputs are provided, with the unbalanced inputs converted to balanced before entering the amplifier itself. This “Super Balanced” design provides the highest quality music, while keeping noise at a minimum. All of this produces one of the most musical amplifiers available.
Special attention has been paid to ensuring that the amplifiers can deliver the power that is required at any given moment. Massive twin low-noise toroidal power transformers provide power to no less than four selected pairs of output devices fed by four audiophile-grade smoothing capacitors per channel. Each channel is carefully temperature-controlled for optimum operating characteristics and efficiency. The result is a clear, open sound with deep controlled bass.
With balanced analogue inputs and 12-volt trigger, G57 compliments both Meridian 800 and G Series in either a two-channel system, or, as the main channels of a high performance analogue theatre when combined with G55.
Meridian “Super Balanced” technology provides balanced operation from single ended connections, providing more music with less noise.
Dual binding post per channel allow for bi-wiring of passive loudspeakers for clearer sound and better bass.
Single-ended and balanced inputs ensure the broadest compatibility with any stereo or surround controller.
Capacitor free signal path ensures fast and accurate low frequency control for outstanding bass reproduction.
12-volt on/off triggers make for simple and care free operation.
Standby mode maintains voltage rails eliminating “warm up” time for instant, optimum sound quality.
Full DC/thermal protection for carefree operation at any volume level
