BroaMan’s Mux22 was originally conceived as a series of application engineered devices offering multiple signal support in a compact 1RU chassis. This combines 3G/HD/SD-SDI I/O with Optocore and SANE digital audio networks, transporting video, along with audio and data, on a single duplex fiber.

Now BroaMan has added to the series with a Mux22 BNC Intercom version. The new board allows the connection of up to eight intercom panels or matrix ports using coax cable in AES3id standard (a 75-ohm BNC electrical variant of AES3). The coax connectors can, of course, be also used to interface with any AES3id device.

There are eight bi-directional AES BNC ports, each of which can handle 2-In and 2-Out.

As always, audio routing is possible between AES ports and any other audio interfaces provided by Optocore or BroaMan (such as analog, Cat5 or copper AES and fiber or coax MADI).

In total the 1RU device features video; 8 x 3G-SDI channels; audio: 16-In/16-out; 4 x GPIO or RS485; Sync I/O; 2 x LAN; 2 x SANE/LAN; 2 x Optocore links; fiber tunnel for generic protocol. It can all be transported over a single duplex fiber to another Mux22 (point to point) or Route66 (network) device.

Explaining the rationale behind this new solution, BroaMan Technical Sales Manager Maciek Janiszewski, stated, "We've been supporting all major intercom manufacturers for many years. Now, along with Cat5 and generic connectivity, we are offering AES/EBU on BNC interfacing. This has been a frequently requested feature and we can happily say that now we cover all connectivity options with intercom systems.

“Furthermore, thanks to the new card, we are able to provide a more robust, and very popular coax connector for digital AES3 signals to interface different audio products. This an extremely useful feature, especially for live production.

“Finally, the new board allows us to pack even more audio channels in a very high density 1RU Mux22 chassis.”
