Meridian Multichannel Power Amplifier G55 Specification Sheet

G55 Multichannel Power Amplifi er
Meridian's G Series line of high performance
digital & analogue consumer audio components
feature a stylish cabinet design in traditional
black or a sleek silver fi nish.
Designed to be either free-standing or rack-
mounted, G Series components build on their
predecessors, the multi-award-winning 500 and
our fl agship 800 Series, and include entirely new
circuitry developed specifi cally for the G Series.

Full installation confi guration of many G Series
components is achieved by running a special
setup program on a Windows computer,
connected to the G Series unit via a serial link,
or direct from the front panel.
G Series products also include serial ports for
remote operation and confi guration, along with
infra-red sensor input and trigger capabilities,
plus Meridian communications ports. A compre-
hensive back-lit learning/programmable remote
is included with products other than amplifi ers.

Although Meridian is today best-known for its
digital circuitry, it is a company built on ana-
logue roots, and indeed, superb analogue circuit
design and implementation are important parts
of all Meridian products.
The G Series power amplifi ers offer the ideal
way to interface G Series components to third-
party passive loudspeakers. They include the
latest power amp developments from Merid-
ian, utilised in their fl agship DSP8000 digital
loudspeaker systems, and share many common
design parameters.
In all cases, pairs of channels can be bridged for
additional output and fl exibility, and the amplifi -
ers in the range are gain-matched to further add
to the possibilities when building a system.
The Meridian G55 is a fi ve-channel unit, and
delivers a solid 100W continuous mean power
per channel into 8Ω.
Special attention has been paid to ensuring
that the amplifi ers can deliver the power that's
required at any given moment. Massive twin
low-noise toroidal power transformers provide
power to no less than 25 selected pairs of
output devices, carefully temperature-con-
trolled for optimum operating characteristics
and effi ciency. The result is a clear, open sound
with detail as well as punch where it's required
– at any volume level from a string quartet at
midnight to Metallica at high noon.
The amplifi er modules feature a symmetrical
design with fully electronically-balanced inputs.
