When you need an advanced intercom system for flexible operation, look to the AVN-TB20AD from Sonifex, a desktop analog and networked talkback intercom with versatile connectivity and RAVENNA/AES67 AoIP functionality. Compatible with both legacy 4-wire audio distribution systems and new AoIP networked audio infrastructure, the AVN-TB20AD delivers professional intercom performance for any broadcast, recording, or TV studio as well as for theaters and OB truck communications. This intercom provides broadcast-quality 24-bit / 48 kHz linear PCM audio distribution and a bright, adjustable OLED screen for navigation.
The AVN-TB20AD features a multitude of useful functions for any communication system, including advanced acoustic echo cancellation, built-in microphone AGC (automatic gain control), 20 illuminated key-cap buttons (three programmable), webserver-based settings adjustment, and wide ranging analog connectivity (XLR, 1/4", and RCA) as well as both RJ45 AES67 or RCA S/PDIF digital audio options. This intercom unit sports both AC and DC power input options for handling any application and supports speaker and microphone mute, callback with source display, and a very large number of headphones and headsets from 32 to 600 Ohms.
- XLR 3-pin electronically balanced microphone input with 48V phantom power
- 1/4" headphone jack and XLR 5-pin headset I/O
- Unbalanced RCA stereo inputs and outputs
- S/PDIF RCA digital input, balanced RJ45 RAVENNA I/O
- 2 x gigabit Ethernet ports and 1 x SFP fibre port
- 15-way D subminiature terminal for GPIO functions
- IEC AC input and 4-pin DC input
Two monitor buttons allow for routing audio directly to the speaker, such as to take an IFB feed or an off-air transmission signal. Signals can be ducked or mixed when a talkback input is received to the speakers or headphones. Three user defined buttons can be programmed for different functions, such as for Group Talk. Buttons are available for microphone mute (cough) and speaker mute actions and these can be controlled remotely by GPI or network commands.
