G61DS v1.5 - 20051103 REÆ’
The G61 combines controller and surround
processor functions, meeting the latest THX
Ultra 2 specifications and including the latest
superb-quality AAC, MPEG, DTS, Dolby, Trifield
and Ambisonic (both 2-channel UHJ and B-
Format, to 4, 5, 6 or 7 speakers) decoding. The
decoders consist almost exclusively of our own
code, giving them superior integration with the
Meridian design philosophy, as well as superior
performance.
The G61s Smart Source feature continually
monitors the digital inputs and automatically
loads the correct decoding software for the for -
mat, speaker layout and encoding of the incom -
ing signal. This capability is enhanced by MHR
SmartLink, which provides a digital link between
a Meridian optical disc player and processor,
carrying explicit information about the nature of
the datastream as well as encrypted high-resolu -
tion digital signals from DVD-Audio -“ the first
system of its kind to be approved. Virtually all
other manufacturers oblige you to go through a
D/A-A/D chain, losing quality in the process.
You can also store separate user parameters
for each source (such as DVD) depending on
whether the incoming signal is stereo or sur -
round, so that any source material is played with
the DSP mode of your choice.
The G61 features eight analogue outputs for
front, rear, centre and sub connections, plus two
additional outputs for other applications. Ten
digital surround outputs are provided, including
front, rear, side, centre/sub and again include an
additional output pair.
The G61 can be configured with a powerful
Windows graphical set-up application
(downloadable from the Meridian web site),
which allows access to all the units functions
and configuration. However, the G61 can also
be configured extensively from the front panel,
thanks to the comprehensive soft-key based
user interface which is common to all the G
Series components. Wizards lead you through
the configuration procedure, allowing a power -
ful degree of customization without having to
hook up a computer.
The G61s firmware can be updated via serial
link with files downloaded for the Meridian web
site.
Contact your Meridian dealer for a demonstra -
tion of the G61 and other G Series components,
along with Meridian DSP Loudspeakers, which
form an ideal complement to them.
