Descriere
Meridian G57 2 Channel Power Amplifier
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.
SINGULAR PERFORMANCE
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.
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.
Sharing many common design parameters developed for the power amplifiers in Meridian’s flagship DSP8000 Digital Loudspeaker systems, G57 is designed to provide the best performance with any passive loudspeaker. These innovations include a unique, ultra-low-feedback design and capacitor-free signal path. These combine to provide incredible control and speed for fast tight bass and outstanding sound quality from a passive loudspeaker.
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.
FEATURES:
- Two discrete 200-watt mono amplifiers ensure maximum channel separation perfect for high performance stereo systems.
- 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

Explicatii in ceea ce priveste rodajul echipamentelor, cat si al cablurilor, asezarea optima a echipamentelor in camera de auditie, importanta acusticii camerei si nu in ultimul rand sistemul de alimentare a intregului echipament:
PENTRU BOXE:
- Pentru performante optime este necesara pozitionarea boxelor la o distanta de minim 30-40cm de peretele din spate pentru boxele cu bass-reflex in spate, pentru cele cu bass-reflex in fata, recomandam pozitionarea la o distanta de 10-20cm fata de peretele din spate, dar totodata la o distanta de cel putin 50cm fata de peretii laterali. Tineti cont de faptul ca orice piesa de mobilier din incapere, joaca rol de absorbtie fonica, dar si de difuzie fonica daca acestea din urma sunt din materiale ceramica sau oglinzi, geamuri sau alt material reflectorizant. In acest sens, gasiti pe blogul nostru, multiple articole care va pot ajuta
- Boxele vor ajunge sa functioneze in parametrii recomandati de producator, dupa minim 50 de ore (ideal 100 ore) de functionare la volum mediu. In aceasta perioada de timp, de “rodaj a boxelor”, sunetul va fi la inceput mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce boxele vor functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate. Exista boxe care necesita un „rodaj” mai amplu de minim 300 de ore mai ales in cazul celor care au difuzoare de kevlar, carbon sau alte materiale de acest tip. Boxele care se „rodeaza” cel mai repede sunt cele care au difuzoare de celuloza.

PENTRU AMPLIFICATOARE, DAC-URI, PREAMPLIFICATOARE, RECEIVER STEREO & HOME CINEMA, SURSE DIGITALE AUDIO-VIDEO:
- Pentru performante optime este necesar „rodarea” echipamentului, In functie de complexitatea componentelor din aparatul dumneavoastra acesta poate dura intre 30-200 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca acesta este alimentat corect conform manualului de utilizare la 220-230 Volti si trece semnal audio sau video dupa caz prin el.
- Echipamentul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce echipamentul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
- In ceea ce priveste echipamentul video precum videoproiector, TV, media player, blueray player, necesita un "rodaj" de cel putin 50 de ore. Lipsa acestuia nu va poate oferi maxim de performanta. "Rodajul" se efectueaza prin simpla utilizare a acestuia, intr-un mod conform specificatiilor mentionate de producator.
PENTRU CABLURI:
- Pentru performante optime este necesara „rodarea” cablurilor, In functie de complexitatea conductorului folosit, cat si geometriei acestuia, „rodajul” poate dura intre 30-100 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca va trece semnal audio sau video dupa caz prin el.
- Cablul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, pe masura ce cablul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
