The Meridian HD621 HDMI Audio Processor is the vital link between your Meridian system and the latest sources, such as Blu-ray Disc®, satellite/TV receivers and gaming consoles with HDMI outputs.

The HD621 seamlessly integrates multiple HDMI sources – including 3D video – into your Meridian system. There’s even a programmable lip-sync delay to ensure sound and picture remain in perfect synchronisation. The HD621 also separates the HDMI signal from up to six sources into audio and video elements, maximising the audio quality and keeping it free of video pollution.

The HD621 supports both 2D and 3D video formats and features some of Meridian’s highest performance enhancement technologies, including digital audio up- and down-sampling, FIFO buffering, resolution enhancement and lip-sync control.

• Six-input HDMI switch and HDMI video output.
• Extracts up to eight channels of high-resolution audio from the HDMI data stream, supplying them to separate audio-only outputs.
• Smartlink coaxial digital audio output (up to 8 channels).
• Multichannel Meridian High Resolution (MMHR): balanced digital audio output via RJ45/Cat 5 cable (up to 8 channels).
• Supports both 2D and 3D video formats.

• Can be easily integrated with a Meridian audio/video system and controlled by it, for example, switching the HDMI input when the appropriate selection is made via the system controller.
• Keeps HDMI video signals away from your audio equipment, minimising signal degradation caused by harmonic interference by high frequency video signals.
• A configurable audio delay system is built in, allowing you to ensure that sound is always in perfect synchronisation with the picture.
• Six front panel LEDs indicate which input is currently active.
