Introduction

The 818 Reference Audio Core

Incorporating the advanced technology from Meridian’s

popular 808 Signature Reference CD Player, the

Meridian 818 Reference Audio Core is a stereo audio

controller with a wide range of digital and analogue

inputs.

Outputs

The 818 Reference Audio Core provides two Meridian

SpeakerLink connectors for simple, straightforward

connection to Meridian DSP Loudspeakers via Cat 5

cables.

Alternatively, balanced and unbalanced analogue

outputs are provided for connecting to an external

power amplifier or preamplifier.

The digital outputs support MHR (Meridian High

Resolution) and operate at up to 96kHz 24-bit.

Inputs

On the input side, the 818 Reference Audio Core

provides a wide range of possibilities.

The 818 Reference Audio Core provides a network

socket to connect directly to a Sooloos network,

allowing it to play music from and control a Sooloos

Digital Media System.

Three SpeakerLink inputs are provided for connecting

to other Meridian sources with SpeakerLink outputs.

In addition, three digital coaxial S/PDIF inputs and five

Toslink optical digital inputs are provided, for connecting

to other digital sources. All digital inputs operate at

sample rates up to 96kHz.

A USB B-type connector is provided to allow the 818

Reference Audio Core to be connected to a computer

system and used as an external sound card.

Six stereo analogue inputs are provided on gold-plated

phono connectors.

Audio processing

The 818 Reference Audio Core features high-quality

audio processing. Analogue inputs are converted to

digital at 96kHz sampling, and digital inputs accept

signals up to 96kHz. High resolution files may be

replayed from a Meridian Sooloos Digital Media System

or a computer connected to the USB input.

Signals are processed with Meridian’s exclusive

apodising filter that ensures maximum audio quality

with outputs at 96kHz/24 bit (digital) or 192kHz/24 bit

(analogue).

When used with Meridian DSP Speakers, the 818

Reference Audio Core provides additional audio

processing in the speakers, such as treble and

bass tone controls and enhanced room boundary

equalisation.

System integration

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 818 Reference Audio Core 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.
