The G92 is a DVD player, controller
Meridian’s G Series line of high performance
digital and analogue consumer audio
components feature a stylish cabinet design
in traditional black or a sleek silver finish.
Designed to be either free-standing or rack-
mounted, G Series components build on their
predecessors, the multi-award-winning 500
and our flagship 800 Series, and include
entirely new circuitry developed specifically
for the G Series.
(preamplifier) and tuner, with multichannel
analogue and digital output capability and a
robust slot-loading DVD-ROM drive. As the
heart of a complete stereo or multichannel
audio/video system, the G92 offers an
alternative to the G95 for the user who
already owns multichannel power amplifiers
(included in the G95) or wishes to employ
Meridian digital loudspeakers to create a full
digital theatre system.
Digital upsampling/buffering delivers a
spectacular improvement in quality
ROM drive improves error-correction
over ten times
AM/FM RDS tuner or DAB Digital
Radio with FM
Multi-layer boards reduce system noise and
improve performance. In products which
include video capabilities, broadcast-quality,
wide-bandwidth video components are
employed for maximum image integrity.
G Series units are easy to use. Where
appropriate, a knob is included to control
volume. The positive-action front-panel
keys are software-defined: their legends are
presented in the vacuum fluorescent display
and change intelligently according to context.
The G92 plays audio CDs, MP3 CDs,
Video CDs, and DVD-Video including
the DVD side of DualDisc hybrids. It can
decode Dolby Digital, DTS, MPEG, and
MP3 data streams to PCM for stereo, and
in some cases multichannel, playback, and
it can optionally output Dolby Digital, DTS,
and MPEG bitstreams for connection to a
surround controller such as Meridian’s G61
or G68.
The G92 incorporates a two-channel
preamplifier with two coax digital inputs,
two optical inputs, and three analogue
inputs. It provides analogue and digital
multichannel and fixed auxiliary digital
stereo outputs. Digital signal processing is
included to upsample (stereo only) decoded
streams, or decode surround bitstreams
from external sources. It also includes a
high-quality FM/AM tuner with RDS/RDBS
(G92 model), or a DAB/FM tuner (G92-
DAB).
Full installation configuration of many G
Series components is achieved by running
a special setup program on a Windows
computer, connected to the G Series unit via
a serial link, or direct from the front panel.

G92
DVD Player Controller Tuner
The G92 includes upsampling in stereo,
which allows digital filters to be placed far
beyond the range of human hearing, as
well as offering other audible benefits right
across the audio band, including improved
transient response. All processing is at
48-bit precision. This results in a more
open, transparent sound, tighter bass, and
a generally more ‘musical’ sound overall.
To drive the multichannel analogue outputs,
signals are upsampled to 176.4/192kHz for
digital to analogue conversion – DACs can
offer better performance at higher sampling
rates – and 88.2/96kHz is used for the
digital outputs, all at 24-bit word lengths.
Here again, sending 24 bits at high
sample rates via an S/PDIF link reduces
jitter as compared to the original 44.1kHz,
16-bit signal from a CD, for example. In
addition, high-resolution digital outputs are
encrypted, removing cyclic components
from the data stream and further reducing
jitter.
The G92 forms the perfect heart of an analogue or digital surround system, and the latter is
shown here. In fact, the G92 will drive any combination of analogue and digital speakers in a
surround system (though it is advisable to use identical speakers for left and right of each pair).
The analogue outputs are driven by 24-bit DACs that are upsampled to 176.4 or 192 kHz for
maximum fidelity, and the digital outputs offer up to 24-bit, 96 kHz sampling – the highest quality
available today from multichannel digital source material. The output level is controlled by the
front panel knob or via remote.
All these advanced digital processing
features are handled by a powerful DSP
engine delivering an impressive 150MIPS
(million instructions per second).
The G92 supports almost any kind of video display device, whether composite, S-Video,
Component (progressive or interlaced) or even the latest interfaces such as HDMI or DVI.
Different video inputs are converted to all formats, so there is only need for one display
connection.

G92
DVD Player Controller Tuner
G92 DAB rear panel
In addition, the G92 incorporates
digital surround decoding to allow the
multichannel analogue and digital outputs
to be used to drive a 5.1 surround
system directly, based on Meridian
DSP Loudspeakers and/or conventional
analogue amps and speakers.
The G92 includes a unique broadcast-
quality, high-resolution video processor/
scaler which combines both Meridian and
Faroudja Video Optimization technology.
This processor can receive composite,
S-video, and interlaced component video,
and convert between the formats, or to the
HDMI (high-density multimedia interface)
standard, to provide a single video output
for all the video sources in your system. A
bypass function allows progressive or high
definition component video to be routed
directly to the component output only.
The HDMI port supports a wide range of
high quality digital video options including
480p, 576p, 720p, 1080i and 1080p
– the same resolution as the best HD
sources. The analogue component output
is available at 480p and 576p.
The video processor includes picture
controls, available via the MSR+ and front-
panel display. For the internal DVD and
external video inputs you can adjust the
the horizontal/vertical picture position. In
addition, the brightness, contrast, colour,
and hue (NTSC) are adjustable on the
video inputs.
The built-in surround processing system
decodes 5.1 Dolby Digital or DTS
soundtracks from DVD-Video discs, and
Dolby Digital or DTS data streams fed
into the external digital inputs. It will also
synthesise a full surround image from
2-channel soundtracks on audio CDs or
DVD-Video discs, or from the external
two-channel digital or analogue inputs, by
extracting latent surround information in the
recording.
The HDMI port also delivers high-resolution
digital audio to the HDMI v1.1 specification,
either up to six channels of PCM at up to
24-bit, 96kHz or a 5.1 bitstream, while
broadcast-quality video circuitry delivers
the most advanced, high-quality video
available today.
The HDMI output can be connected to a
DVI input if the device supports HDCP
copy protection, using a suitable adaptor
cable.
Several DSP presets are provided to
allow you to choose the type of surround
processing used for different sources. For
5.1 audio formats a Discrete or Cinema
DSP preset is selected automatically,
depending on whether the source is
music or a movie. For two-channel audio
formats the DSP preset can usually be
switched between Trifield (Meridian’s
acclaimed three-speaker stereo decode,
recommended for music), Stereo (uses
just the main left and right speakers
and subwoofer if present), or PLII
(recommended for movies), using the DSP
key on the front panel or MSR+.
On the video side, advanced video circuit
designs, matched phase video filters, and
a broadcast-quality video encoder are
employed to deliver low-noise images of
outstanding colour depth and resolution.
Separate ultra-low jitter master video and
audio oscillators allow picture and sound to
be independently optimised, ensuring that
the G92 DVD player delivers breathtakingly
clear pictures.
G92 features a slot-loading DVD-ROM drive
