HDMI TO HDMI AUDIO(SPDIF+R/L) CONVERTER

HDMI to HDMI Audio (SPDIF + R/L) Converter – Seamless Sound Separation from Elvatech

In today’s multimedia-driven world, your audio-visual setup is only as good as its weakest link. Whether you’re a home theater enthusiast, gamer, streamer, or AV technician, you’ve likely run into a common issue: your HDMI signal carries brilliant video, but your sound system needs a different connection type.

That’s where the HDMI to HDMI Audio (SPDIF + R/L) Converter, available at Elvatech, enters the picture—quite literally and sonically.

Designed to bridge the compatibility gap between HDMI video sources and non-HDMI audio receivers, this smart converter extracts high-quality audio from your HDMI stream and outputs it to SPDIF (optical) or analog stereo (R/L RCA)—all while maintaining full HDMI video pass-through.

What is the HDMI to HDMI Audio Converter (SPDIF + R/L)?

This compact device takes an HDMI input—say, from a Blu-ray player, PlayStation, PC, or streaming stick—and splits the signal:

• HDMI video continues to your TV or projector

• Audio is routed simultaneously to your optical sound system or analog speaker system

It’s a modern solution for audio systems that lack HDMI inputs. It also solves compatibility issues for older amplifiers, surround receivers, and soundbars that can’t decode audio directly from HDMI.
