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, Aux, Disc, Tape, TV, Cable, Sat,
VCR1, VCR2, and Game.
The Aux source usually corresponds to the internal
Sooloos interface and the VCR2 source usually corresponds to the USB input.
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
To play music from a Sooloos system
Either:
• Press Source (front panel or under the front panel) until the display shows SLS, or press the Aux key on the remote.
Or:
• Select the 818 zone from the Sooloos controller.
You can then listen to music streamed from the
Sooloos server.
The volume and mute controls on the Sooloos controller will operate the 818.
To control the Sooloos system
When the SLS source is selected you can control the
Sooloos system from the 818 front panel controls.
• Press >= (front panel) or * , = , and > (remote) to control playback.
• Press [ or ] (front panel or remote) to step between tracks in the Sooloos play queue.
For more information please refer to the Meridian
Sooloos Network Card Guide.

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.
When you first connect power to the 818 Reference
Audio Core the volume is set to 65, which is similar to the mid-way position of the rotary volume control on a conventional preamplifier.
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 30) 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 or bass
The 818 Reference Audio Core provides sophisticated treble and bass controls, to allow you to adjust the broad balance of a Meridian DSP loudspeaker system to correct for the acoustics of your listening room, or for a misbalanced recording.
These controls are performed by the DSP loudspeakers, and are only available if your 818
Reference Audio Core is set up with fixed outputs.
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.
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.

Using the 818
Reference Audio Core
12
Using the 818
Reference Audio Core
Changing the balance or phase
The 818 Reference Audio Core balance control uses digital signal processing to compensate for an offcentre listening position by delaying and diminishing the sound in one speaker, thus effectively shifting the speaker’s image back.
You can also change the absolute phase of the signal, to compensate for signals which are out of phase, giving an unnatural-sounding bass.
If the 818 is set up with fixed outputs the balance control is performed by the DSP loudspeakers.
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.
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) or
Phase ( Function = on the remote) to change the phase.
Or:
• Press Phase ( Function = on the remote).
The display will show the new phase setting.
For example: SLS Phase-
Changing the loudness or subwoofer mode
The 818 Reference Audio Core allows you to control several other settings supported by recent Meridian
DSP loudspeakers.
The Loudness control alters the frequency response to make music sound more natural when played at a low volume setting.
The Mode control changes the distribution of bass between the main speakers and the subwoofer to suit different types of material.
These controls are only available if you are connected to DSP loudspeakers that support them, using the SpeakerLink connection, and if
SpeakerLink On mode is selected (see Setting up
SpeakerLink, page 32).
Additional controls may be available as further
SpeakerLink features are developed.
To change the loudness
• Press < or > (remote or under the front panel) until the display shows the current loudness setting.
• Press A or V (remote or under the front panel) to turn the loudness control on or off.
For example: SLS Loudness On
To select Music Mode or Movie Mode
• Press < or > (remote or under the front panel) until the display shows the current mode.
For example: SLS Music Mode
• Press A or V (remote or under the front panel) to select between Music Mode, recommended for classical music, and Movie Mode, recommended for movie soundtracks.

Loudspeaker setup controls
The 818 Reference Audio Core provides several controls to allow you to adjust DSP loudspeakers to suit the characteristics of your room.
The Subwoofer control adjusts the subwoofer crossover frequency and gain.
The Location control adjusts the sound to compensate for the placement of the main speakers.
The Room Ht control adjusts the speakers according to the height of your room.
The EBC control adjusts the sound to compensate for highly reflective walls.
The EBA control improves the bass alignment in
DSP loudspeakers that support it. Note that the extra processing adds a time delay, so it should be disabled for video sources.
These controls are only available if you are connected to DSP loudspeakers that support them, using the SpeakerLink connection, and if
SpeakerLink Setup mode is selected (see Setting up SpeakerLink, page 32).
To change the subwoofer crossover
• Press < or > (remote or under the front panel) until the display shows the current subwoofer mode.
For example: SLS Subwoofer 1
• Press A or V (remote or under the front panel) to select between: Off (subwoofer off), 1 (80Hz crossover), or 2 (120Hz crossover).
To change the subwoofer gain
• Press < or > (remote or under the front panel) until the display shows the current subwoofer gain.
For example: SLS Sub. Gain 0
• Press A or V (remote or under the front panel) to adjust the relative subwoofer gain between -15 , 0
(the normal setting), and +15 in 1dB steps.
To specify the speaker location

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).
One unit will then be designated as the controller.
The display shows:
The displays show:
Controller
All the other units will be configured as non-controllers.
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 30.
Each unit will display: Auto 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.
