Meridian 558.2 Multichannel Power Amplifier Meridian's new 558.2 Multichannel Amplifier is designed in the Meridian tradition of uncompromised music performance. Modern music and film systems have complex amplification requirements, comprehensively met by the 558.2. Film soundtracks demand speed, power and dynamic range. CD and DVD-Audio music recordings require these attributes as well as the ability to provide low-level detail and convey the space and ambience of the original performance. |

To deliver stable dynamics the 558.2 uses a new design of low-noise twin 1.2kVA toroidal mains transformers and no fewer than 50 pairs of hand-matched output devices. In addition an important new dynamic bias system has been incorporated. Utilising technology designed for the flagship DSP8000 Loudspeaker System, the 558.2 is maintained at optimum operating temperature no matter what source material is being played. This enables low listening levels to be sweeter and richer while still being able to provide extraordinary dynamics when driven hard. Its switchable, bridged modes make it flexible. The 558.2 can be configured for either five-channel output at 200W per channel into 8 ohms, or for two channels at greater than 500W into 8 ohms plus a single channel at 200W. For seven-channel applications it is possible to run two 558.2 amplifiers with the front three channels bridged.
