The Meridian 557 houses two powerful amplifiers in a dual mono construction.
The amplifiers are both rated at 200W into 8 ohms. Each over-specified output
stage uses 8 high-power transistors. These, combined with a massive low-
noise 1.6kVA toroidal transformer, permit this amplifier to deliver currents in
excess of 30A, ensuring no loss of performance even into loads that dip below
2 ohms. The massive power delivery of this amplifier makes it ideal for driving
difficult loudspeaker loads.
557 can be operated in bridged mode giving power in excess of 680W into 8
ohms, 1000W into 4 ohms.
The 557 provides balanced and unbalanced inputs as well as twin outputs for
bi-wiring.
The topology of 557 is very much in the Meridian tradition. A high-precision fast
DC-precise input stage is combined with a fully complementary amplification
and output stage. Also, the 557 uses Meridian’s well established self-adjusting
bias and error-correction output topology.
The 557 is fully protected against DC and thermal overload. A proprietary
Meridian soft-start circuit is also fitted.
