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 our 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.
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.
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.
