Meridian Audio G92 - Manual (Page 3)

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.
All these advanced digital processing
features are handled by a powerful DSP
engine delivering an impressive 150MIPS
(million instructions per second).

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.
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.
