Introduction

The 808.2 Signature Reference CD Player

 

The 808.2 Signature Reference CD Player takes Compact Disc playback to an entirely new level, with a heritage that includes the multiple award winning 508 and 800, and two dozen optical disc players from 1984 to the present day. The 808.2 is specifically designed as a CD-optimised machine, able to play audio CDs, CD-Rs, and CD-R/Ws. It also plays the CD layer of an SACD disc.

At the heart of the 808.2 are fully-integrated electronics and a computer-style CD/DVD-ROM drive. The drive normally operates at standard CD speed, but is capable of much faster reading, using multiple high-speed re‑reads to ensure accurate recovery of data from even the most difficult disc. This capability alone provides over ten times the error correction of a conventional CD player.

Signal Processing

Once the digital data stream has been recovered from the disc, powerful on-board digital signal processing (DSP) with a capability of an impressive 150 MIPs upsamples the digital information from the 16-bit 44.1kHz signal of conventional CD to a 24-bit signal with a sample rate of 176.4kHz. This signal is fed

to the latest DVD-Audio quality delta-sigma DACs to drive the analogue outputs, while a digital signal at an 88.2kHz sample rate is supplied to the digital outputs. Upsampling is performed with very high-accuracy filters which minimise pre-echo arising from ADCs and DACs used in the recording and replay process so that the total chain closely represents transmission of sound through air, for ultimate transparency from a CD source.

The 808.2 employs a triple buffering system to minimise jitter, and therefore maximise HF transparency and stereo image precision and stability. This, and

the digital electronics as a whole, are driven by a new design of high-stability clocking system which further reduces jitter and ensure 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.

Integrated preamplifier

The 808.2i version of the 808.2 Signature Reference CD Player includes a built-in stereo preamplifier with the ability to handle six stereo analogue inputs, three digital coaxial S/PDIF inputs, and two Toslink optical digital inputs, making it ideal as the heart of a superb stereo system.

System integration

The 808.2 Signature Reference CD Player provides balanced and unbalanced analogue outputs for connecting to an external power amplifier or preamplifier. Alternatively, it provides SpeakerLink and coax digital outputs, allowing it to drive Meridian DSP Loudspeakers directly. The digital outputs support MHR (Meridian High Resolution) and operate at up to 2 x CD sample rate (88.2kHz), 24-bit.

Meridian Comms sockets (2 x DIN) allow communication with other Meridian components, while an RS232 interface provides full remote control capability as well as the ability to configure the unit with Meridian’s innovative Windows-based graphic configuration application. Three programmable trigger outputs are provided for direct control of external devices, for example powering-up amplifiers, etc.

The Meridian 808.2 Signature Reference CD Player is supplied with the MSR+ learning/programmable remote control, which not only operates all Meridian products but also includes an extensive database of third-party products and the capability to learn commands from existing remotes.
