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.
