Sonifex AVN-TB10AR 10 Button Advanced Talkback Intercom, AoIP Rackmount Portal

Sonifex AVN-TB10AR 10 Button Advanced Talkback Intercom, AoIP Rackmount Portal

The AVN-TB products are IP audio based talkback intercom units with an advanced feature set, allowing them to be used in multiple applications. With both 4-wire analogue inputs and outputs, as well as AoIP network audio connectivity, the AVN-TB units can be used with existing legacy 4-wire systems and with new AES67 AoIP networked audio infrastructure. Additionally, all audio is at 48kHz sample rate, meaning that it’s broadcast quality audio as standard.
