Draco vario HDMI - Digital Audio Features

Oberteuringen, January 23, 2014 – IHSE’s new HDMI extenders support the following digital audio standards:


•    Stereo Linear Pulse Code Modulation (LPCM)
•    DTS-HD (5.1)
•    Dolby Digital
•    Dolby Digital Plus (5.1)

at a bit depth of 16-24 bits and sample rate of 32-192 kHz, depending on the mode.

This eliminates the need for additional audio modules, enabling the playback of the audio signal directly at monitors with integrated loudspeakers.

Alternatively, these audio standards can be transferred via a digital audio interface, using our optional upgrade module for digital audio. HDMI extenders can be used in combination with any Draco vario extenders for transmission of DVI + digital audio. 

This enables multiple combinations for video and audio transmission.

The new HDMI CON Unit with local CPU support can function as a KVM switch, to enable transmission of local HDMI audio signals via simultaneous HDMI output at the CON Unit and an optional digital audio upgrade module.
