Expert 2C

Transmit two camera sources at the same time

The Expert 2C is the first bonded transmitter that encodes 2 streams at the same time and unleashes the long time promised full remote production. With the Expert 2C it is possible to do multi camera shoots without the need of a OB van on site. The Expert 2C supports both H.265 and H.264 encoding to insure an end to end compliancy using standard based decoders or IRD’s. Besides IFB the Expert provides a return data signal to do remotely camera control for white balance and color correction. The Expert 2C offers, beside the live option, also a recording feature which records the video on the internal solid state disk. The recordings are transferred using the store and forward mode providing the highest quality possible.


For the WMT Multicam productfleet we offers this special developed decoder, the 4C1. This decoder is similar to the WMT4C, our 4 camera transmitter, a 2U rack unit  It has 4 audio inputs and outputs for intercom to overcome separate de-embedding. The 4C1 has 4 times HD-SDI outputs with embedded 8 audio channels of which 4-8 is the return audio from the intercom. 


The unit supports transmission via Ka-sat and has a default storage capacity of 120 GB which can be upgraded until one TB. To meet everybody’s requirements, the EXPERT 2C is available as a 1U 19-inch rack mount (SL-4C) or as a backpack solution. Other available accessories are a high gain dome antenna, hot swap battery plates and antenna extenders for car roof top mounting
