558 Multi Channel Amplifier

Introduction

There are many multi-channel amplifiers on the market today. Many of these were designed in haste out
of a necessity to answer a market need. The new 558 Multi Channel amplifier was designed from the
ground up in the Meridian tradition of uncompromised music performance.

Modern music and film systems have complex amplification requirements. Film soundtracks demand
speed, power and dynamic range. High performance music systems needs include these attributes as
well as the ability to convey low-level detail and a sense of space.

The 558 uses twin 1.2 KVA torroids and 50 pairs of hand matched output devices. Its switchable bridge
modes make it as flexible as it is powerful. The 558 is rack mountable for ease of installation.

The new Meridian 558 multi channel amp is truly a powerful solution for any analog music and film
system.
