other equipment in the system.

for information

about operating it.

CD player models

This Installation Guide applies to the G07 24-bit CD Player and

G08 24-bit Upsampling CD Player. The main differences between

each of these products are given in the following table:

I n t r o d u c t i o n

G07 24-bit CD Player

The G07 incorporates advanced design – both digital and

analogue. Multi-layer PCBs, four separate power supplies, the latest

surface-mount technology, carefully selected audiophile-quality

components, and of course Meridian’s signature quality design and

manufacturing.

The latest laser assembly is used in the G07, and is optimised for

CD, CD-R, and CD-RW playback. In addition, the player will replay

most hybrid discs, as well as DTS CDs for external decoding via the

digital outputs.

The G07 maximises audio quality by reducing jitter to extremely

low levels, for a smooth, open, well-defined sound and pinpoint

stereo imaging. This is achieved by re-clocking the digital outputs

and using a superb direct-coupled audiophile-quality output

amplifier.

The G07 utilises 192kHz, 24-bit capable digital to analogue

converters for the very highest analogue quality, while the internal

circuitry includes a superb analogue design that complements the

high-spec DACs and delivers 2V RMS with less than -90dB noise

and distortion.

The result is dramatic stereo imaging, and a clear, open, and

authoritative sound.

Both S/PDIF coaxial and TOSlink optical digital outputs are

provided, and all audio cable interfaces are via gold-plated

connectors.

An RS232 serial port is provided for remote control operation. This

port can be used to update the G07’s system software, thanks to

Flash ROM storage.

G08 24-bit Upsampling CD Player

The G08 is able to play virtually any compact disc, from

conventional pressings to CD-R, CD-R/W, and discs of MP3 files

(64-256kbps). In addition, the player will replay most hybrid discs,

as well as DTS CDs for external decoding via the digital outputs.

At the heart of the G08 are fully integrated electronics and

a computer-style CD-ROM drive. Although it normally runs at

standard CD speed, the drive is capable of spinning the disc much

faster, allowing multiple high-speed re-reads to ensure accurate

recovery of data from even the most difficult disc. This feature

alone provides 10 times the error correction of a conventional CD

player.

Once the digital data stream has been recovered from the disc,

powerful on-board Digital Signal Processing (DSP) with the

capability of an impressive 150 MIPS (million instructions per

second) upsamples the digital information from the 44.1kHz,

16-bit signal of conventional CD to 24 bits, and to a sample rate of

176.4kHz for digital to analogue conversion to drive the analogue

outputs, and 88.2kHz for the digital outputs.

Upsampling enables filtering to take place far beyond the range

of human hearing, as well as offering other audible benefits right

across the audio band, for ultimate transparency from a CD source.

The G08 employs a triple buffering system to minimise jitter. This

maximises high-frequency transparency and stereo image precision

and stability.

This, and the digital electronics as a whole, is 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. Multiple power

supplies ensure that digital and analogue circuitry are kept apart

and can provide the required power when called upon to do so.

The G08 player includes both balanced (on XLR connectors) and

unbalanced (on phono connectors) two-channel analogue outputs.

S/PDIF (Sony/Philips Digital Interface, IEC 60958) digital outputs

are also provided and both optical (TOSlink/EIAJ) and coax digital

formats are included. In addition, the digital outputs support

surround-encoded bitstreams such as those derived from DTS-

encoded CDs, which can be replayed via an external decoder.
