BroaMan's Flexible MUX-22 Leads the Way at NAB 2014


BroaMan’s increasingly popular MUX-22 video, audio and intercom I/O module, which offers up to 16 3G/HD/SD-SDI I/O configurable video ports (with built-in CWDM multiplexer), is continuing to evolve.

Part of the complete BroaMan (Broadcast Manufactur) portfolio, which provides scalable, protocol independent routing, repeating, transport and distribution of multiple professional video signals over optical fibre, MUX-22’s flexible and compact redundant video, audio, data transport and basic routing platform can be seen at this month’s NAB 2014 Show in Las Vegas.

MUX-22 can be delivered as a mixed unit with up to 16 3G/HD/SD-SDI channels as well as selectable audio modules (analogue, digital MADI or AES/EBU); four wire ports for Clear-Com (IC422), RTS (IC485) or generic intercom (IC444) with 4 Line In, 4 Line Out, 4 GPI and 4 GPO; MADI module, with 4 duplex SC MADI ports; 16 AES/EBU ports on Phoenix or RJ45 connectors; all contained in just 1 RU (Rack Unit).


“MUX-22 is hugely economical, both in terms of space and power consumption,” says BroaMan managing director, Tine Helmle. “The video, audio, intercom and data are all contained in a 1RU package, while the low power draw further underpins the low cost of ownership.

“This module has already been recognised by a large number of customers, and we have sold them in quantity to Videohouse (via Amptec Belgium) for their OB Vans, France TV (via Le Team), TV2 Danmark (via Danmon), while BP Satellite Solutions are using them for Formula One … and many more.”


MUX-22 is fully featured, and includes: Input always reclocked (output with optional reclocker); Optional sync module with tri-level sync or black burst or word clock I/O; full Optocore integration with SANE ports, Ethernet, RS485/422 or GPIO; Intercom boards for 4 x Clearcom/4x RTS/4 x AES based intercom systems/4 x analogue intercom with GPIO or 4 x optical MADI ports; Fibre tunnel for third-party devices, similar to 1Gbit switches or other fibre utilities; Optional redundancy available.

The output can be derived from any source in the system, while the Tri/Bi-level video clock input and output module can be installed in the device on request.

The MUX-22 also seamlessly integrates into the Optocore digital optical network system. Analogue audio, 4-wire intercom for Clear-Com or RTS user panels or matrices, MADI or AES/EBU are sent transparently through the optical network together with video, Ethernet and serial data. Each audio and data channel can be routed to, and from, every device on the network using the Optocore control software, which enables the monitoring of video signals, displaying the status of each SFP (optical transceiver module) built into the device.


Aside from being populated with SDI I/O and multiplexers, in accordance with the customer’s specifications, MUX-22 is equipped with a built-in redundant power supply with an automatic switchover in case of fibre failure.

Finally, MUX-22 units can be used in multiple different applications, starting from a very simple point-to-point link between OB truck and remote location, but can also be used in a redundant ring topology or with BroaMan Route66 units, as a part of large routing solution.
