The UHD121 integrates seamlessly into modern home installations, delivering Meridian’s signature sound performance from today’s TVs with ease.
UHD121 connects your TV to Meridian loudspeakers via HDMI eARC, delivering both audio and volume control through one streamlined link. Supporting high-resolution audio up to 24-bit/192kHz, it ensures every soundtrack is presented with clarity, depth and richness, transforming ordinary viewing into an extraordinary listening experience.
Compact and discreet, the UHD121 connects directly between a TV’s HDMI eARC/ARC port and Meridian DSP loudspeakers via SpeakerLink. Fully CEC enabled, the system powers on and off with the TV, and volume is controlled from the TV’s own remote. This delivers a seamless experience: high-performance sound with simple, intuitive control — no extra remotes, no additional steps. Unlike generic eARC adapters, UHD121 is a manufacturer-engineered, audiophile-grade controller designed for integrators and the Meridian DSP ecosystem.
