Meridian’s C Series offers a range of robust, precision-made audio/video components

designed with the custom installation market in mind, extending Meridian’s strong

reputation for the highest possible audio and video quality into new areas.

The line includes power amplifiers, surround processors and all the building-blocks of a

powerful system for custom installation applications. All are fitted with rack-mounting

ears and are equipped with remote control capability where appropriate.

The elegant matte-black rack-mount enclosures include a removable, transparent front

panel inset which can be removed for access.

PRELIMINARYMERIDIAN C SERIES

The Meridian C52 combines the finest

materials with state of the art design

to create what we believe is a superior

subwoofer controller, emphasising

extreme bass, depth, clarity, control, and

articulation.

Each unit provides two controller and

power amplifier channels allowing the

use of two independent subwoofers.

Both digital and active analogue inputs

are provided, allowing the C52 to be

connected either to a digital surround

controller or digital source with a

digital coax output, or to an analogue

preamplifier or surround controller with

either phono or balanced outputs.

Digital connectivity

The unit employs 96kHz/24bit digital-to-

analogue conversion and accept digital

inputs up to 96kHz including those

carrying MHR signals.

Separate analogue and digital power

supplies are used to feed the C52’s

precision electronic circuits, ensuring that

both high and low power sections receive

continual smooth supply.

If you are using the subwoofers with a

digital source, such as CD or DVD, the

signals remain in digital form until the last

possible stage.

Subwoofer drivers

The C52 is designed to be used with

Meridian Installation Series subwoofer

driver assemblies such as the SW320.

However, passive subwoofers with

similar specifications and capabilities may

alternatively be employed.

Power amplifiers

The C52 includes Class D high efficiency

ultra low output impedance amplifiers,

optimised for both music and movie

soundtracks.

The whole electronic assembly is supplied

from substantial toroidal transformers

feeding high-quality, audiophile-grade

capacitors.
