 IQMUX42-49 family of modules provides a highly flexible solution for all HD-SDI 1.5 Gbps or SD-SDI 270 Mbps multiplexing/demultiplexing operations. Handling up to 16 audio channels (eight AES/EBU streams) makes them ideal for both multi-lingual and discrete surround sound applications. Fully compatible with Dolby E compressed audio the IQMUX46-49 includes a ‘Dolby E mode’ for automatic synchronization to the video frame boundary, whether already embedded in the incoming SDI or on discrete AES inputs. Additional audio processing features include tracking audio delay, gain, phase invert, channel level routing, and audio mixing. Video features include proc. amp controls, HANC/VANC blanking and up to 12 frames of delay.

The sophisticated audio processing features include comprehensive audio delays, gain control, phase inversion and mixing. Both AES input pair routing and separate channel level routing are included. The module is fully Dolby E™ compatible and can handle other non[1]PCM audio streams including Dolby AC3 (Dolby Digital) passed as AES data. The module has 16 channels of standard AES I/O and also provides an additional pair (one AES stream) for monitoring or other basic output functions providing a total of 18 channels of audio access on one module.

Unlike other audio processing modules these units also have dedicated video control features that include video ProcAmp controls and up to 12 frames of video delay. This allows the IQMUX42-49 to be employed as the prime control unit in a processing chain providing all audio and video controls required to prepare signals.

 Video capabilities extend to a large 12-frame video delay that can work in conjunction with the sophisticated delay features available for the audio channels. Delay can be inserted in the video path to compensate for audio processing. It can also be inserted in the audio path to compensate for video processing. It can be inserted in both to simply re-time the complete signal. The audio delays can be both fixed and can track video synchronizers to keep sound in perfect sync with the pictures. The audio delay capability can be used for non PCM audio so that Dolby E sources can be delayed either to match the video or to re-time the Dolby blocks to realign with the video frames if necessary.
