The AU-11HB Audio Source to HDMI Bridge is designed integrate audio only sources into video distribution systems. It will accept digital (optical) or analogue (L/R Stereo) audio signals and output them over HDMI. This clever device also adds a 'blue-screen' video feed into the HDMI signal path so that any HDMI AV receiver or display will accept the audio signal for sound reproduction. It allows audio signals from any source to be easily integrated into a HDMI system which is particularly useful when distributing independent audio and video sources via a HDMI or HDBaseT matrix, including the ability to seamlessly integrate SONOS.
AU-D250 is designed to integrate and convert both analogue and digital
audio signals into any AV system. This device has an in-built sample
rate converter which can upscale audio signals between 44.1kHz to
192kHz (24 bit). With HDMI connectivity, allowing the user to embed or
de-embed audio within the HDMI signal path, the AU-D250 not only
provides a truly enhanced listening experience, but also the
flexibility to manage all audio signals in your AV system.
