818v3 Reference Audio Core
Network Audio Player/Preamplifier
Product highlights
Reference preamplifier featuring
Meridian enhancement
technologies such as triple FIFO
buffering, DSP upsampling and
apodising filters to deliver the very
best performance from any digital
source.
Overview
Since its introduction in 1998,
Meridian’s 800 Reference Series has
provided a platform from which the
company has been able to showcase
the very best in surround sound, DVD,
CD, and network music playback.
Through regular updates and
iterations, it has also proven to be an
outstanding benchmark against which
performance standards have been set
throughout the audio industry. 818,
now in its third iteration, benefits from
almost 20 years of 800 Series product
innovation.
Meridian’s Audio Core concept combines
the source connectivity features of a highperformance preamplifier with a full suite
of proprietary resolution enhancement
technologies, and provides connectivity
to Meridian’s unique range of DSP
Loudspeakers. In addition to its external
source connectivity, with digital inputs
supporting decoding of MQA sources for
studio quality replay, also provides
an internal digital media source through
a network connection to any Meridian
Sooloos Digital Media System.
Maximum quality & I/O flexibility
is the highest performance twochannel preamplifier and Digital Media
System end-point manufactured by
Meridian.
Connecting at the centre of an incredible
Meridian music system, offers simple
networked integration with any Meridian
Sooloos Digital Media System plus an array
of other sources including MQA.
features twin SpeakerLink outputs
for “home run” connection in an all-digital
system with any of Meridian’s SpeakerLink
equipped DSP Loudspeakers. And as part
of the Reference Series, features
superb, high-quality analogue pre-amplifier
outputs via both balanced and singleended connectors, ensuring can also
be used in more traditional audio systems,
where sophisticated DSP algorithms
feeding the analogue outputs result in an
even sweeter sound than before.
Meridian’s SpeakerLink connection system
delivers the highest quality digital signals to
Meridian’s DSP Loudspeakers on discreet,
low-cost cables with simple connectors.
SpeakerLink helps make a Meridian system
easier to install and far less intrusive
than other high-end audio systems. The
advantage of the twin SpeakerLink output
is that left and right loudspeakers can both
be connected directly to the , further
simplifying wiring structure and making
cables even easier to hide.

Balance, Enhanced Bass Alignment and
Enhanced Boundary Control can be set
from the Audio Control unit.
