The Performer C22 System Interface converts two two channel CAT5 matrix ports to two phantom powered digital belt pack lines and vice versa, allowing seamless integration of digital partylines with matrix intercom systems. In addition it can also be used for any application, where you would like to route digital partyline intercoms via an AES digital audio infrastructure such as MediorNet, Artist or any 3rd party AES audio router solution supporting transparent AES user bit transport. The device provides an internal matrix, allowing to either operate the two ports independently as two independent partylines or to build one distributed partyline via AES. The belt packs are connected to the 19" / 1 RU unit via standard 3 pin XLR cables. The Performer C22 can power daisy-chains of up to nine belt packs, split-boxes or desktop speaker stations per line.
