This is an amazingly flexible and precise unit. See our matching 818 pre-amp.
The Meridian G57 is a solid, reliable, 2-channel unit, delivering a powerful 200W continuous mean power per channel into 8Ω, or up to a full kilowatt bridged into 4Ω.
The ampliﬁer modules feature a symmetrical design with fully electronically-balanced inputs. Both balanced and unbalanced inputs are provided, but in fact the unbalanced inputs are converted to balanced before they enter the ampliﬁer itself, using Meridian’s proprietary ‘superbal’ technology.
The discrete active input components are thermally and electrically matched in pairs, and the ampliﬁers feature active bias control throughout, with thermal sensing that carefully manages the temperature and current ﬂow at different volume levels.
Fully DC-coupled, the signal path contains no capacitors, while those in the power supplies are audiophile grade components.
The ampliﬁers are of a unique low-feedback design for minimum transient and interface distortion, offering superb clarity and transparency right across the audible range, with an output impedance that is extremely low and suitable for virtually any high-quality third-party passive loudspeaker system.
Trigger and other control signals are optically isolated from the ampliﬁer itself. When in standby mode, a standing voltage is maintained on the power rails and supply components. As a result, you do not have to wait for half an hour after switching on for optimum performance to be achieved: it is there at once.
Two sets of outputs are provided per channel for bi-wiring, etc, on sturdy binding posts color-coded for easy reference and capable of handling large-diameter high-quality loudspeaker cables. The output terminals are connected to the ampliﬁers by Van Den Hul silver-strand cable to avoid signal losses.
The ampliﬁer can be operated in bridge mode by actuating a switch on the rear panel, in which case the left channel input becomes the input for the bridged pair and the inner output terminals are bridged, power being derived from the outer terminal pairs.
The ampliﬁers include electronic protection reset by power-cycling, with full DC and thermal protection.
A front-panel indicator shows when the ampliﬁ er is in standby. When the unit is activated, an LED illuminates for each channel. In the event of thermal overload, the main indicator goes red and the channel lights go out, showing that the unit is off-line. A push button on the front panel can be used to take the unit in and out of standby, while ﬂexible 5–30V AC/DC trigger capability allows ampliﬁer power to be controlled remotely along with the rest of the system.
