In professional AV, the digital signal processor is where good audio becomes great audio — where the signals from multiple microphones get mixed correctly, where acoustic echo cancellation prevents the microphone from capturing and returning the loudspeaker output, where the audio is routed to the right destinations, and where the entire audio system is managed as a unified, coherent whole. Biamp is one of the leading manufacturers of DSP systems for commercial conference room and facility audio, and BCS Consultants is a certified Biamp partner.
This guide explains the Biamp Tesira product ecosystem and how it applies across different commercial audio applications.
Biamp TesiraFORTÉ: A Standard in Conference Room DSP
The Biamp TesiraFORTÉ is the DSP platform that appears in professional conference room, boardroom, and large-venue AV installations worldwide. It is a hardware processor that receives audio input from microphones and other sources, applies digital signal processing to each signal, and routes the processed outputs to speakers, codecs, and recording systems.
What the TesiraFORTÉ does in a conference room:
Acoustic Echo Cancellation. When audio from the far-end participants plays through the conference room speakers, the microphones in the room would normally pick up that speaker audio and send it back to the far end — creating a distracting echo. AEC processes the speaker signal as a reference and subtracts it from the microphone signal in real time, removing the echo before the audio reaches the far-end codec. Without AEC, far-end participants hear their own voice returned with a delay.
Automixing. In a conference room with multiple microphones, only the active speaker's microphone should be fully open at any given moment — having all microphones open simultaneously captures ambient noise and room reflections from every pickup point. The TesiraFORTÉ's automixer constantly evaluates the signal level at each microphone input and opens only the microphone closest to the current speaker, while others are attenuated.
Signal Routing and Mixing. Complex conference room AV installations route audio to multiple destinations simultaneously: the far-end codec for the video call, the room speakers for local reinforcement, a recording system, and sometimes a secondary room or overflow space. The TesiraFORTÉ manages all of these routing decisions in a configurable, network-controlled signal flow.
The TesiraFORTÉ is available in multiple hardware configurations depending on the number of inputs and outputs required, from analog-input models such as the TesiraFORTÉ AI to Dante- and AVB-equipped models for large, networked installations.
Biamp Devio: All-in-One Conferencing for Medium Rooms
The Biamp Devio is a compact, all-in-one USB conferencing hub designed for medium conference rooms where a full TesiraFORTÉ installation is not warranted. The Devio provides USB audio connection to a laptop or conferencing system, with onboard AEC and automixing for microphones, and a speaker output for the room.
Devio models pair with compatible table and ceiling microphones to provide professional conference room audio quality in a simpler, more cost-effective hardware package than a full TesiraFORTÉ system, and compatibility with specific microphones is confirmed during design. For medium conference rooms with six to ten seats, the Devio is the right balance of capability and installation simplicity.
Biamp Cambridge Sound Management: Sound Masking Integration
BCS Consultants' sound masking installations for open offices, healthcare facilities, law firms, and call centers frequently use Biamp's Cambridge Sound Management platform — acquired by Biamp and integrated into their product portfolio. The Cambridge QtPro system provides the signal generation, distribution, and zone control for commercial sound masking installations in both direct and indirect field architectures.
For facilities deploying both Biamp conferencing audio and Biamp sound masking, the two systems can run on the same network infrastructure, simplifying the IT footprint for the facility's audio systems.
Biamp TesiraLUX: AV-over-IP for Distributed Video
TesiraLUX is Biamp's AV-over-IP platform, extending the Tesira ecosystem from audio into video distribution. TesiraLUX encoders capture video from any HDMI source and distribute it over a standard IP network, with TesiraLUX decoders receiving the video stream and outputting to displays throughout the facility. For large facilities with distributed display needs — digital signage, video distribution to overflow rooms, multi-room video conferencing — TesiraLUX provides a scalable, standard-network-based alternative to dedicated AV matrix switchers.
Crestron and Biamp Integration
The most common configuration in a professionally designed conference room is Biamp TesiraFORTÉ handling audio processing, Shure MXA series handling microphone pickup, and Crestron handling room control and programming. These three platforms work together natively: the TesiraFORTÉ communicates with Crestron via the Tesira control protocol, allowing the Crestron touch panel to manage volume, mute, input selection, and audio routing from the unified room control interface.
BCS Consultants programs this three-way integration as a standard element of every boardroom and large conference room installation, ensuring that the room occupant interacts with a single, simple control interface while all three systems coordinate their responses appropriately.
Choosing Between TesiraFORTÉ, Devio, and Other Biamp Options
The right Biamp product follows the room's complexity, not its prestige. A small or medium room with a handful of microphones and a USB codec may be well served by a compact all-in-one unit such as Devio. A boardroom with multiple microphone zones, several output zones, recording, and Crestron control usually justifies a TesiraFORTÉ. Facilities with many rooms on one network often move to networked audio so that signals can be shared and managed centrally.
Design and configuration are done in Biamp's Tesira software, where inputs, processing, and routing are built and tested before the hardware is on site. BCS Consultants keeps the configuration files, labels every input and output, and documents the signal flow so that future service visits start with accurate information. For rooms being upgraded, existing speakers and microphones are evaluated for reuse rather than replaced by default.
Lifecycle planning matters as well. Firmware, license, and support options should be reviewed at purchase, and a documented backup of the DSP configuration should be stored with the client's other IT records.
Common Biamp Design Mistakes and How to Avoid Them
Most problems with DSP-based audio come from the design stage rather than the hardware. Examples include gain structure that clips at the first input, echo cancellation references that do not include every speaker feed, microphones that are left open with no automixing, and routing that works in the lab but not when a second room is combined with the first. Careful design reviews and a written signal flow prevent most of these.
Another frequent issue is inadequate commissioning. Each microphone should be tested individually, echo cancellation should be given time to converge during a live call, and the control system should be tested through every mode of the room. BCS Consultants documents the settings so that a future engineer can understand the original intent.
Training and Support for Biamp Systems
A DSP is only helpful if the people who support it understand it. BCS Consultants trains the client's IT or AV staff on the basics of the configuration, the control interface, and common troubleshooting steps, and leaves them with the saved configuration and a labeled signal-flow diagram. For clients who prefer a managed approach, ongoing support agreements cover monitoring, firmware updates, and prompt response when a room has an audio problem.
Frequently Asked Questions
What is the difference between Biamp Tesira and TesiraFORTÉ?
Tesira is the broader platform architecture, encompassing multiple hardware models and the software tool for system design and configuration. TesiraFORTÉ is the specific hardware model in the Tesira line designed for conference room DSP applications — it provides the AEC, automixing, and conferencing-specific signal processing that makes it the right choice for conference room audio. Other Tesira hardware models address different applications in the platform's range.
Does Biamp equipment work with both Microsoft Teams and Zoom?
Yes. Biamp DSP systems connect to the conferencing platform through the codec's USB or analog audio interface — the DSP is platform-agnostic. Biamp also offers Tesira collaboration solution bundles that are certified for Microsoft Teams Rooms and include the appropriate configuration for direct Teams Rooms integration.
How long does a Biamp TesiraFORTÉ system take to design and program?
System design and programming time depends on the complexity of the installation — the number of inputs and outputs, the signal routing requirements, and the Crestron integration. A standard boardroom TesiraFORTÉ installation often requires one to two days of engineering time for design and programming. Very large or complex multi-room systems require more.
Can a Biamp system be managed remotely?
Yes, in most cases. Tesira systems are network devices that can be monitored and adjusted through Biamp's software when a secure connection is available, such as through the organization's VPN. Remote access lets support staff check status, review settings, and resolve many problems without a site visit, while changes to the production configuration should still follow the organization's change-control process.
