When you need an advanced intercom system for flexible operation, look to the AVN-TB10AR from Sonifex, a 19" rack-mounted 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-TB10AR 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-TB10AR features a multitude of useful functions for any communication system, including advanced acoustic echo cancellation, built-in microphone AGC (automatic gain control), 10 illuminated key-cap buttons (3 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.

Sonifex's range of AVN (Audio/Video/Network) talkback/listening/paging intercoms aid communication between studios, stages, theatres, offices, and different areas in a facility or building complex. It has both 4-wire and AoIP sources and destinations, and use RAVENNA/AES67 as the audio transport mechanism, allowing simple Cat 5 cabling and expansion. The unit can also act as a PTP master clock or slave clock and supports IEEE1588-2008 PTPv2 media and default profiles.

The AVN-TB10AR is a 10-channel talkback intercom with enough analog and digital I/O to facilitate inter-building communications for a wide range of environments. Connection options include:

• XLR 3-pin electronically balanced microphone input with 48V phantom power
• 1/4" headphone jack and 2 x 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 mini-XLR 4-pin DC input

Each AVN-TB talkback unit has a built-in webserver for setup and configuration. The webserver is responsive and resizes, depending on the size of your screen, meaning that it can be used on large monitors or small handheld devices such as smartphones. Help information is shown on the right-hand side of the screen, so it's a good place to go to find out how the unit operates.

The AVN-TB10AR is a 10-button intercom meaning that 10 other stations can be defined, one per button, for communication. Comms can be made as a Talk action, a Listen action, or a duplex Talk/Listen action to/from each station. The Page button is used to speak to all stations (or a defined list of stations) and Group Talk functions can be enabled to page particular groups of stations.

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.
