Product Highlights

Reference preamplifier featuring Meridian enhancement technologies such as FIFO buffering, DSP upsampling and apodising filters to deliver the very best performance from any digital source.

  • Connects directly to a Meridian Sooloos Digital Media System to make the 818v3 an audio endpoint.
  • Full range of analogue and digital inputs allowing the 818v3 to handle all your sources, with Meridian enhancements on the digital inputs.Standby mode maintains voltage rails for instant warm-up.
  • Magnetically isolated design maximises audio quality.
  • Meridian SpeakerLink connection for ultimate quality and convenience of installation when driving Meridian DSP Loudspeakers.

User Features

  • The 818v3 features twin SpeakerLink outputs for “home run” connection in an all-digital system with any of Meridian’s SpeakerLink equipped DSP Loudspeakers.
  • A diverse range of high-performance audio inputs, both analogue and digital, allow audio sources to be switched and processed using the same powerful audio enhancing DSP as the internal Digital Media source.
  • Simple, high-qualityUSB connection to a personal computer allows the 818v3 to function as an external soundcardwhen connected to a personal computer and perfomance is limited only by the source signal.
  • The 818v3 also supports the playback of DSD sources via DSD-over-PCM (DoP) from a suitable media player via USB or S/PDIF inputs which accept sources up to 192kHz, 24 bit.
  • Features such as Bass, Treble, Balance, Enhanced Bass Alignment and Enhanced Boundary Control can be set from the Audio Control unit, with Bass, Treble and Balance adjustment provided on the analogue outputs.


Meridian’s Audio Core concept combines the source connectivity features of a high-performance preamplifier with a full suite of proprietary resolution enhancement technologies, providing connectivity to Meridian’s unique range of DSP Loudspeakers.
