SY-EM-UHD-EX
4K UHD HDMI Audio Embedder / Extractor
with ARC
sy.uk 2V1.0
The SY-EM-UDH-EX audio embedder and extractor is an extremely versatile device, providing a
means to either embed another audio signal onto the HDMI output or extract HDMI audio signals
from the HDMI input. Three audio interface connections (Optical Toslink, digital Coax, and stereo
L/R) are employed, ensuring a convenient interface to any sound system.
The L/R and Coaxial audio signal ports can be set to either input (embed) or output (extract)
mode. The embedded audio can be selected from one of the three input types: optical, digital
coax or stereo analogue.
The simultaneous audio outputs can be either from the ARC channel or the audio extracted from
the incoming HDMI. Supported audio formats include 2 channel LPCM, Dolby AC3, and DTS.
Features
Can be set to either Embed or Extract audio signals to or from HDMI
Supports three audio signal types: optical, digital coax or stereo analogue L/R
Supports all resolutions to 4K UHD HDMI video
HDCP 1.4 and ARC supported
Selectable audio input for audio embedding mode
