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.
If you are using DSP loudspeakers you can connect a headphone amplifier, such as the Meridian Prime
Headphone Amplifier, to the analogue outputs for headphone listening. A headphone mode is provided to mute the loudspeakers when listening on headphones.
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.
A SpeakerLink input is provided for connecting to other
Meridian sources with SpeakerLink outputs. In addition, two digital coaxial S/PDIF inputs and two Toslink optical digital inputs are provided, for connecting to other digital sources.
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 192kHz. 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).
The 818 Reference Audio Core will also decode MQA
(Master Quality Authenticated) audio streams. It can extract the finest of details from music and deliver the audio for rendering either to its own analogue outputs, or to an attached DSP loudspeaker system. The front panel display will indicate MQA as will any attached
DSP loudspeaker system that can recognise the stream.
When used with analogue loudspeakers the 818
Reference Audio Core can provide tone adjustments as well as balance and volume controls.
When used with Meridian DSP Speakers, the 818
Reference Audio Core provides control of 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.

Switching on and off
When not playing, the 818 should be left in the standby state. This uses a minimal amount of electricity, but ensures that the components of the 818 operate at maximum efficiency from the moment you start.
If you are not going to use the 818 for several days you should switch the unit off completely at the rear panel, and disconnect it from the AC power supply.
To switch on from standby
• Press Source (front panel), or select a source on the remote.
If the 818 is part of a Meridian system it will automatically switch on any other units in the system, such as the 861 Reference Digital Surround Controller and Meridian DSP Loudspeakers.
To switch to standby
• Press Off (front panel or remote).
If you have other Meridian equipment or Meridian DSP
Loudspeakers connected to the 818 these units will also switch to standby.
Selecting a source
The 818 responds to the following 12 source keys on the remote:
CD, Radio, DVD, SLS, Disc, Tape, TV, Cable, Sat,
PVR, USB, and Game.
The input associated with each of the sources depends on how the 818 has been set up; for more information refer to the Meridian Configuration Program Guide.
Your installer may have customised the labels displayed for each source to suit your other equipment.
To select a source
• Press Source (front panel or under the front panel) until the display shows the source you want, or press the appropriate source key on the remote; eg CD .
The display shows the source and volume setting.
For example, if you select the Radio source:
The display shows: Radio 65
The 818 mutes the sound while you change source.

Using the 818
Reference Audio Core
Adjusting the system volume
The 818 Reference Audio Core provides a volume control which can be adjusted from the front panel or remote control. The volume changes in precise steps of
1dB, where 9dB is equivalent to doubling the loudness.
The current volume setting is displayed in dB on the front-panel display, and can be varied in the range 1 to
99dB.
You can choose what startup volume is set when you switch the 818 on; see To set the startup volume, page
36.
To restore the sound
• Press Mute again.
Alternatively, the sound will be restored if you adjust the volume.
If the 818 is set up with variable outputs (see
Choosing a standard setting, page 34) the analogue output level is varied, allowing the 818 to drive an amplifier or active loudspeakers. If the 818 is set up with fixed outputs the volume control is performed by the DSP loudspeakers.
To change the volume
• Press Volume A or Volume V (front panel),
Volume + or Volume – (under the front panel), or the red A or V keys on the remote.
As you adjust the volume setting the display shows the current volume level.
For example: CD 65
To mute the sound
• Press Mute (front panel, remote, or under the front panel).
The display shows: Mute
Changing the treble, bass, or balance
The 818 Reference Audio Core provides sophisticated treble and bass controls, to allow you to adjust the broad balance of the sound to correct for the acoustics of your listening room, or for a misbalanced recording.
The controls are more subtle than conventional tone controls, and take advantage of digital signal processing techniques to provide a more natural adjustment of the frequency response.
The balance control uses digital signal processing to compensate for an off-centre listening position by delaying and diminishing the sound in one speaker, thus effectively shifting the speaker’s image back.
These controls only affect the analogue outputs when the 818 Reference Audio Core is set up with variable outputs.
To change the treble
• Press < or > (remote or under the front panel) until the display shows the current treble.
For example: SLS Treble +1.0
• Press A or V (remote or under the front panel) to change the treble.
The treble control tilts the frequency of the response over the entire frequency range to make the sound brighter or dimmer. It can be adjusted between ±10db in 0.5dB steps. Normally settings between +1.0 and
-2.0 will give the most natural results.
To change the bass
• Press < or > (remote or under the front panel) until the display shows the current bass setting.
For example: SLS Bass +1.0
• Press A or V (remote or under the front panel) to change the bass.
The bass control allows you to adjust the bass response in the room by ±5dB in 0.5dB steps.
Normally settings between +3.0 and -2.0 will give the most natural results.
To change the balance
• Press < or > (remote or under the front panel) until the display shows the current balance.
For example: SLS Balance <0>
• Press A or V (remote or under the front panel) to move the listening position.
The display shows the direction and position of the listening position.
For example: SLS Balance <3
The arrow indicates the direction, and the number indicates the position where 0 is central, 8 is in line with the corresponding main speaker, and 10 is fully to one side.

Changing the axis or phase
Larger models of the DSP loudspeakers have an axis control that allows you to compensate for the height of the listener relative to the tweeter.
You can also change the absolute phase of the signal, to compensate for signals which are out of phase, giving an unnatural-sounding bass.
The axis control is only available if your 818 is set up with fixed outputs.
To change the axis
• Press < or > (remote or under the front panel) until the display shows the current axis setting.
For example: SLS Axis -1
• Press A or V (remote or under the front panel) to change the axis.
The axis can be adjusted between -2 and +3, where
0 corresponds to the axis of the treble unit. Usually a listener will be below that position, so we recommend settings of -1 or -2.
To change the phase
Either:
• Press < or > (remote or under the front panel) until the display shows the current phase.
For example: SLS Phase +
• Press A or V (remote or under the front panel) to change the phase.
Or:
• Press Function = on the remote.
The display will show the new phase setting.
For example: SLS Phase -
To store the tone settings
If you are using SpeakerLink loudspeakers or your 818
Reference Audio Core is set up for variable output you can store your preferred treble, bass, and axis settings in the 818.
• Press Function Store (remote).
The display shows: Tones Stored
Adjusting the sensitivity of sources
This section explains how to use the input gain menu to set up the analogue sources connected to the 818.
To adjust the sensitivity of a source
To obtain the best signal-to-noise ratio for your analogue sources you can adjust the sensitivity of each input to give the highest level that does not produce clipping.
• Set Input Gain Menu to Show ; see Setup parameters, page 35.
• Select the source you want to adjust, with loud source material playing.
• Press < or > (remote or under the front panel) until the display shows the current sensitivity.
For example: Radio 2.0V In
• Press A or V (remote or under the front panel) to change the sensitivity.
You can select between sensitivities of 0.5V (most sensitive), 1.0V, 2.0V, or 2.5V (least sensitive).
If the sensitivity is set too high the input will clip the loudest passages. The display shows:
For example: Radio 0.5V In Clip
In this case reduce the sensitivity.
If you have selected a digital source you cannot adjust the sensitivity. The display shows:
For example: CD Not Analogue

For example: SLS MQA 384k
Headphone mode
The 818 Reference Audio Core provides a headphone mode, which mutes the outputs to DSP loudspeakers.
This allows you to connect a headphone amplifier, such as the Meridian Prime Headphone Amplifier, to the analogue outputs for headphone listening. For more information see To connect to a Meridian Prime
Headphone Amplifier, page 31.
This option is only available if your 818 Reference
Audio Core is set up with fixed outputs.
To select headphone mode
• Put the 818 into standby by pressing Off (front panel or remote).
• Press < or > (remote or under the front panel).
The display shows the current headphone mode setting:
For example: Headphone Mode Off
• Press A or V (remote or under the front panel) to change the headphone mode setting.
For example: Headphone Mode On
When you select a source the loudspeakers will be muted, and the display shows Headphone Mode in place of the volume.
For example: CD Headphone Mode
Use the headphone amplifier to adjust the volume of the headphones.
If you want to mute the analogue outputs when not in use, set Relay Mute to Silent; see To set the relay mute mode, page 39. The relay mute acts normally when headphone mode is selected and returns to the silent mode when it is deselected.

In a system of Meridian products, one of the products acts as the controller for the system, receiving infra-red commands from the MSR+ and then, if appropriate, relaying them to the other products via the Comms link.
The following automatic setup procedure should be used to set up the Comms correctly between several products:
• Connect one of the DIN COMMS sockets on the back panel of the 818 to one of the COMMS sockets on another G Series, 500 Series, or 800
Series unit, using the Comms leads provided with the products.
The sequence in which you connect the units is not important.
• Switch all the units to standby.
• Press Clear (remote).
Each unit will display: Auto
One unit will then be designated as the controller.
The display shows:
All the other units will be configured as non-controllers.
The displays show:
Controller
Not Con.
If for any reason the automatic setup does not work, make sure you are operating the remote from a position where all the units can receive the infra-red, and try again.
If this fails:
• Restore the default operation by selecting one of the standard types; see Choosing a standard setting, page 34.
Do not, under any circumstances, connect any equipment other than Meridian G Series or 800
Series to any socket marked COMMS on the back of the product.
Configuring the 818 Reference
Audio Core
This chapter explains how to set up the 818 Reference Audio Core for most standard configurations of your other equipment, using just the front-panel controls and MSR+.

The output mode determines whether the 818 provides the volume control for the analogue outputs.
The SpeakerLink setting is only available if Output
Mode is set to Fixed , and determines whether the loudspeaker settings are sent to DSP loudspeakers connected via the SpeakerLink connection.
If SpeakerLink is set to On , the volume, bass, treble, axis, and balance are sent to the speaker via
SpeakerLink; otherwise they are sent via the Comms connection.
In addition, if SpeakerLink is set to On additional
EBA, position, EBC, subwoofer, and loudness controls are available, and will control those features in DSP loudspeakers that support them.
The following table shows which settings you should choose for different applications:
