The 9305 is an embedded audio delay processor that receives an HD/SD-SDI signal, de-embeds all audio data, allows for independent delay for each channel, and re-embeds the audio into the SDI video stream. The active picture and all non-audio ancilllary packets are left untouched. The card also features user control of gain and polarity for each channel.
An upmixer software option, featuring Linear Acoustic® technology, converts a stereo signal to a representative 5.1 surround signal. The upmix can be manually enabled, or operate in an automatic mode, where the upmixer monitors the input audio for stereo audio and replaces it with 5.1 surround. User controls are also provided for audio center width and surround field depth.
