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).

Outline Specications

Formats

• DVD-Video, DVD-R; Video CD (VCD), CVCD,

MP3; CD Audio (CD-DA), CD-R and hybrids

such as SACD (CD layer only) and DualDisc

Audio inputs

• Analogue: three stereo inputs, unbalanced

0.5–2.5Vrms on phono. Digital S/PDIF: two

stereo coax inputs and two stereo Toslink optical

inputs

Tuner

• AM/FM tuner includes its own 24/96

A/D converter. AM (Long/Medium Wave,

150–285/525–1605 kHz); FM (VHF Band II,

87.5–108 MHz), sensitivity 2µv. DSP processing

System capabilities

• Operates as player or controller, with upsampling

in stereo. As a stereo system, can drive stereo

analogue power amplier and passive speakers

or two Meridian DSP Loudspeakers. As a

multichannel system with on-board surround

decoding, can directly drive 6 channels

of analogue or digital loudspeakers or a

combination

adjustable as 0 or 7.5IRE. 16:9 and 4:3 displays

supported

Video Processor

• Two composite video inputs, one component

input, three S-Video inputs; composite, S-Video,

component and HDMI outputs (DVI-compatible,

HDMI also carries 2-ch audio), outputs all

simultaneously active; selected video input is

converted to all formats at valid resolutions

(except non-interlaced component input

which bypasses processor). Faroudja Video

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.
