UHD121
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.
Flexible system design - daisy-chain or star-wired SpeakerLink connections plus an additional HDMI input for direct source integration.
Luxury sound, simple control - enables Meridian DSP loudspeakers to integrate directly with TVs, all controlled from the TV’s own remote.
Out-of-the-box performance - plug-and-play in most systems, minimising installer time and client training. Works with existing Meridian DSP loudspeaker systems, protecting customer investment and enabling straightforward upgrades.
