TesiraFORTÉ AVB CI

What the TesiraFORTÉ AVB CI does in a meeting room

The TesiraFORTÉ AVB CI is a fixed-I/O digital signal processor built for conferencing spaces. It takes in microphone and line signals, processes them, and sends the result to loudspeakers, recorders and conferencing systems. Its job is to keep speech intelligible for people in the room and for remote participants who join the call through a codec or a PC.

Each of its 12 mic/line inputs carries acoustic echo cancellation (AEC), which stops voices from the far end, played through the room loudspeakers, from feeding back into the microphones. The 8 mic/line outputs let one unit feed several destinations at once, such as a main loudspeaker system, an overflow room or a recording feed.

Specifications that matter when you plan the system

• Inputs: 12 analog inputs with AEC on every input, and +48VDC phantom power at 7mA per input.
• Outputs: 8 analog outputs with a selectable maximum level from +24dBu down to -31dBu.
• USB audio: up to 8 configurable channels at 16- or 24-bit, 48kHz.
• Networking: 128 x 128 channels of AVB, connected over Gigabit Ethernet.
• Control: RS-232 and GPIO for control processors and room automation.
• Power: 100-240VAC, 50/60Hz, less than 35W.

The audio figures in the data include a frequency response of 20Hz to 20kHz, a dynamic range above 108dB at 0dB gain, and 24-bit converters. Input gain adjusts from 0dB to 66dB in 6dB steps, which lets a technician match microphones of different sensitivity during commissioning.

Where it fits in Qatar

In a boardroom in West Bay or Msheireb, one TesiraFORTÉ AVB CI can take ceiling and table microphones, run echo cancellation on each input, and feed the room loudspeakers and a video codec over the network. Its 19.0-inch width and 1.75-inch (44 mm) height suit a rack or enclosure, so the rack position should be agreed before cabling starts.

A university lecture theatre in Education City may need a main loudspeaker feed, an assistive listening output and a recording feed at the same time. The eight outputs cover that list on one unit. A public school in Al Wakrah building an overflow room for assemblies could use the outputs to drive the second room while the main hall keeps its own mix.

What to plan before you order

• Count every microphone and line source and check that the total fits the 12 inputs.
• Plan the cabinet ventilation: the operating range is 0 to 40°C, while Qatar summer temperatures can exceed 45°C.
• Match the USB channel count to the number of conferencing endpoints in the room.
• Book a free site survey so the rack position, cable runs and network switch are checked before installation.

The unit weighs 8 lbs (3.63 kg), so it is light enough to fit into a standard equipment rack alongside other room hardware. The humidity range is 0 to 98% non-condensing and the altitude limit is 2000 metres.
