Meridian Audio G92 - Manual (Page 2)

In stereo mode, the G92 is designed to
connect directly to a pair of analogue active
speakers, or power amplifiers and passive
speakers. Alternatively, it can be connected
to a pair of Meridian DSP Loudspeakers to
create a complete two-channel audio/video
entertainment system.
The G92’s multichannel digital output
allows connection to a surround controller
such as the Meridian G61 or G68.
Alternatively, the digital and/or analogue
multichannel outputs can be used to
create a powerful 5.1 surround system
based on Meridian DSP Loudspeakers or
conventional analogue amps/speakers – or
a combination of the two. Here the G92
really comes into its own: as the heart of a
complete surround system.
The G92 includes a powerful video
processor and scaler which can
simultaneously provide composite
and S-video outputs, plus progressive
component video and up to 1080p on
an HDMI v1.1 output. It provides two
composite, three S-video, and one
interlaced component video input, all of
which can be routed to any of the video
outputs with appropriate scaling.
At the centre of the G92 is a robust, high-
speed computer-style slot-loading DVD-
ROM drive – the best type of drive to use
to ensure accurate data recovery from all
types of disc. The drive normally operates
at standard speed; however, it is capable
of recovering data a great deal faster when
required, enabling it to make more attempts
to recover accurate data from a problem
disc. Thus the drive can perfectly recover
the data from almost any compatible disc.
Unlike other players that use a mechanical
approach to attempt to lower jitter by
minimising drive vibration, the G92 employs
a triple buffering system to minimise jitter,
maximizing HF transparency and sound
stage precision and stability. The result
of this sophisticated approach is that
the players deliver ultra-low jitter, with
sound and picture quality second only to
Meridian’s 800 Reference DVD/CD Player.
The digital electronics as a whole are
driven by a new design of high-stability
clocking system which further reduces jitter
and ensures that the highest level of detail
is recovered from a disc. All digital data is
accurately re-clocked, and multiple power
supplies ensure that digital and analogue
circuitry are kept separate.
The G92 includes a comprehensive
front-panel user interface which allows
access to all the features of the unit. The
player can be set to a standard ‘Type’
which configures all the required settings
as required for a particular application.
In addition, an on-screen display (OSD)
allows you to configure specific settings
individually.
The player employs Flash ROM memory for
the operating system, so software updates
can be downloaded from the Internet and
installed via a PC connected to the serial
port on the rear panel. The serial port also
allows full remote control and configuration
of the unit.
The G92 provides three principal
S/PDIF coax outputs designated L/R,
L/R Surround, and C/LFE. These typically
connect to Meridian processors, or
feed a stereo signal to a pair of DSP
Loudspeakers.
If configured for MHR SmartLink they,
or the adjacent combined 15-way
D-type connector, carry high-sample
rate encrypted data from DVD discs
for the highest fidelity of decoding and
reproduction. The SmartLink also informs a
connected Meridian processor of the signal
source, so that it can switch processing
modes automatically. An additional S/PDIF
digital output delivers a stereo downmix or
bitstream signal.
The G92 includes a preamplifier and
integral radio tuner. The main stereo
analogue preamp output is either fixed,
or variable via the front-panel knob which
controls the Meridian proprietary
digital/analogue volume control – a design
similar to that used in the flagship 800
Series and DSP 8000.
Two tuner options are available: AM/FM
and DAB/FM. The former provides AM (LF/
MF) and FM (VHF stereo Band II) reception
with RDS/RDBS, and is fitted with its own
96kHz, 24-bit A/D stage. Digital signal
processing provides a sophisticated FM
stereo blend/width control which allows
you to minimise noise on a received
signal. There is also a DSP-based low-
pass filter and a whistle filter for improved
AM reception. Alternatively, a version is
available with DAB Digital Radio (VHF
Band III and UHF L-Band) and FM. This
option is described in a separate sheet.

The illustration above shows the G92 at the heart of a compact, all-digital, Meridian-based
stereo DVD system. The Meridian DSP loudspeakers take their feed from the G92’s digital
preamp outputs, with the speaker volume controlled by the G92’s front-panel knob via the
communications link, or via the remote. The G92 will also drive a stereo analogue system, for
example with a G56 or G57 power amplifier and your choice of passive speakers, or active
loudspeakers like the M420 in-wall designs.In addition, the G92 will drive a complete 5.1
system comprising either digital speakers or analogue amps and conventional speakers – or
any combination of the two (see panel opposite). With three stereo analogue inputs and four
stereo digital ins (two optical and two coax), the unit will support a wide selection of inputs, and
when playing a multichannel disc as part of a stereo system, the surround information is expertly
downmixed to stereo.
