INTRODUCTION
The CV-505Q HDMI 2.1 Audio Extractor & Embedder is an exceptional device that provides a
practical solution for audio compatibility issues with HDMI 2.1 devices. This device can extract
high-quality stereo analog and digital S/PDIF (Toslink) audio from incoming HDMI signals without

into the outgoing HDMI signal. This capability allows users to incorporate external audio sources into
their HDMI signal, which is beneficial for devices that do not have an HDMI output but require audio
support.
The CV-505Q's ability to co-work with any HDMI matrix on the market is another unique feature.
This allows different audio capacity HDMI-equipped devices to work with multi-channel HDMI audio
insertion simultaneously. The CV-505Q is a versatile device that can operate seamlessly with a broad
range of HDMI devices. Overall, the CV-505Q is a remarkable device that can significantly enhance the
audio experience of HDMI devices, making it a valuable addition to any home theater or audio system.
