Introduction - Meridian C61R Installation Manual

This guide provides full information about unpacking the C61R Digital Surround Controller,
connecting it to the other equipment in the system, and configuring it using the front panel.
Once you have connected and configured the product, refer to the G Series System Guide for
The C61R is a powerful, flexible surround controller, with 8
unbalanced analogue outputs and 10 digital outputs.
At the heart of the C61R is a powerful DSP engine consisting
of three Motorola 56367s running at 150MHz – delivering an
incredible 450MIPS (million instructions per second) capability.
Processing is performed at high sample rates and with 48-bit
precision throughout, ensuring that all filtering, processing, and
other operations are carried out beyond the limits of human
hearing. The C61R is thus a perfect processor for the very latest in
digital audio, such as DVD-Audio and DVD-Video.
Inputs
Analogue signals are converted via a 24-bit Delta-Sigma converter
to high-sample-rate digital on input to the processor, while all
digital signals are reclocked to minimise jitter and maintain total
data integrity. The C61R includes two six-channel S/PDIF digital
inputs (coax), a USB audio input, four TOSlink optical inputs, and

six more stereo coax digital inputs. In addition, there is a six-
channel analogue input, and five stereo analogue inputs.
Formats supported
The C61R combines controller and surround processor functions,
meeting the latest THX specifications and including MPEG, DTS,
Dolby, Trifield, and Ambisonic decoding. In many cases the decoders
incorporate our own code, giving them superior integration with
the Meridian design philosophy, as well as superior performance.
As a result, the C61R can decode surround signals from all PCM
optical discs. The C61R is thus an ideal complement to a G Series
optical disc player like the G98.
Smart Source feature
The C61R's 'Smart Source' feature continually monitors the digital
inputs and automatically loads the correct decoding software for
the format, speaker layout, and encoding of the incoming signal.
This capability is enhanced by MHR SmartLink, which provides a
digital link between a Meridian optical disc player and processor,
