Meridian 218 Zone Controller

MQA Decoding Sooloos Endpoint 

Designed for use in in-room or in-rack, the 218 Zone Controller contains the functionality needed to create a Hi-Res audio zone. Accommodating both local and distributed audio, whether analogue or digital, the Meridian 218 is also an endpoint for the award-winning Sooloos music management platform.

With both digital and analogue inputs and outputs, the MQA–enabled Meridian 218 is suitable for a wide range of distributed audio applications from single zone to multi-zone use. Control features including IP and IR, allow this versatile 1U tall product to be easily partnered with any of Meridian’s power amplifiers or DSP loudspeakers.

TECHNOLOGIES

LIP SYNC

Video processing typically delays the picture. As sound travels slower than light, the effect of the sound arriving before the picture is highly noticeable. For installations where the audio and video are separated before video processing, the Meridian 218 has adjustable audio delay to realign the audio with the video.

FIFORECLOCKING

Clock variations, known as jitter, are one the main causes of unpleasant “glare” in digital audio systems. The Meridian 218 solves this problem with a proprietary jitter reduction technique using a FIFO (first-in first-out) buffer that allows an independent output clock to deliver clock performance that does not rely upon on the incoming signal quality.

DSP UPSAMPLING AND APODISING FILTERS

Almost all audio has been digitally processed, even if it arrives at the Meridian 218 in analogue form. Upsampling allows the Meridian 218’s DACs to run at a higher sample rate and achieve their full potential. Upsampling also provides the opportunity to apply apodising correction to ameliorate time-domain errors that have been introduced to the signal by the ADCs or other upstream processing.

MQA

Master Quality Authenticated (MQA) is a revolutionary end-to-end technology that delivers master quality audio in a file that’s small enough to stream or download.

The Media Source 200 is exceptionally easy to use, and can be operated from the touchscreen of the Control 15, wirelessly from the free iPad or iPhone app, or any other available system controller.

Operation of the 218 as a Sooloos Endpoint requires an existing system core product like the Meridian MC200, QNAP NAS drive or Roon Core on the same network.
