Drivers Library We know a lot about PC drivers Welcome to the PC Matic Driver Library, the internet's most complete and comprehensive source for driver information. Some USB devices, such as printers, scanners, and copiers require that the USB device software and drivers be installed before connecting the USB device to the computer. Always follow the installation documentation from the USB device manufacturer. While troubleshooting the USB device, you might need to disconnect the USB device from the computer.
Tesira offers USB ports on all TesiraFORTÉ models and on the Tesira EX-UBT expanders. The USB interface allows Tesira to be used as a USB audio I/O peripheral for PCs and Macs. Each USB port can be configured in Tesira programming as speakerphone (mono), 2-channel, or multi-channel I/O devices.

The TesiraFORTÉ DSP processor and Tesira EX-UBT AVB expander can be used to receive and/or transmit digital audio via USB to a PC. The USB port is used for audio only; the TesiraFORTÉ DSP processor and Tesira EX-UBT AVB expander cannot be programmed or otherwise accessed via the USB port, and the Tesira USB port does not support video applications.
Both Tesira device types use a USB 2.0 port that operates as a USB Audio Class 1.0 device for 1- or 2-channel operation. Most modern computer operating systems include generic USB Audio Class 1.0 drivers that are compatible with Tesira (including Windows, Mac OS X and Unix-based operating systems), therefore Tesira USB devices can usually be used in mono or stereo mode without manually installing a driver.
For multi-channel USB audio input (3+ channels) in Windows applications Tesira USB devices are USB Audio Class 2.0 devices, which require the Biamp USB audio driver be installed on the host PC. Download the Biamp Tesira USB Driver for Windows.
The USB port on both Tesira devices accept the USB Type B (or standard-B) connector of an A-to-B USB cable. The Tesira devices are USB peripherals and cannot host other USB devices.
USB extending
In Tesira systems with AVB we recommend the Tesira EX-UBT instead of using a regular point-to-point USB extenders. More information on deploying the EX-UBT can be found here.
It is recommended that users consider Dante-USB interfaces in TesiraFORTÉ DAN systems which require USB extensions.
Please note that most USB extenders are not compatible with USB Audio. When using USB extenders ensure that the USB extender supports isochronous data transfers. The majority of USB extenders do not support isochronous data. Biamp is currently in the process of testing various USB extenders and will continue to expand the list of known compatible USB extenders:

Tesira USB Input and Output blocks
When using the TesiraFORTÉ USB Audio, TesiraFORTÉ USB Input and/or USB Output blocks are used. Below are the options available when creating USB Input and Output blocks:
The interface dialog allows a choice of 3 modes of operation:
- Note that the Biamp Tesira USB audio driver is required for Windows OS when using multi-channel mode. Mac OS supports multi-channel audio natively. Windows can only support mono and stereo audio natively without needing to install a USB driver.
Bit depth can be set to 16 or 24 bit with a fixed sampling rate of 48KHz. When using a bit depth of 24 bits, a maximum of 4 audio channels can be sent/received. When using a bit depth of 16 bits, a maximum of 8 audio channels can be sent/received.
USB Input Level
Setting the USB Input levels at -12.0dB will allow a signal sent from the PC at 100% to enter the TesiraFORTÉ at a maximum (peak) of +24dB (0dBFS). This is the correct setting for the USB Input level.
When using the Tesira EX-UBT USB Audio, Tesira EX-UBT USB Input and/or USB Output blocks are used. Below are the options available when creating USB Input and Output blocks:
The interface dialog allows a choice of 3 modes of operation:
- Mono (1 input x 1 output)
- Stereo (2 inputs x 2 outputs)
- Multi-Channel (8 inputs x 8 outputs)
- Note that the Biamp Tesira USB audio driver is required for Windows OS when using multi-channel mode. Mac OS supports multi-channel audio natively. Windows can only support mono and stereo audio natively without needing to install a USB driver.
When configured as a speakerphone, the EX-UBT synchronizes privacy mute state and volume control of Microsoft Skype for Business running on the connected host computer. This is achieved through Human Interface Device (HID) communication.
More information on deploying the Tesira EX-UBT can be found here.
Connecting to a Windows PC
For Windows to recognize the Tesira USB interface, the configuration running in the Tesira system must contain the USB Input and/or Output blocks. The USB port on the TesiraFORTÉ or Tesira EX-UBT is not active unless the Tesira configuration includes USB blocks.
WIth the active USB blocks added in the Tesira configuration, when the Tesira USB device is connected to a Windows machine, it will try to automatically install the required drivers and initialize the USB interface. Once a valid connection is established, the Tesira's USB device will appear as an audio device in Windows. Every time there is a change in the USB options of the Tesira configuration, the host operating system (Windows in this case) will update the drivers if necessary.
Once Windows successfully recognizes and installs the USB interface, the USB Input or Output blocks within the Tesira configuration will give an indication of the Connected and Streaming status.
Drivers Data Card Port Devices Replicator
The Connected indicator will light up when a USB cable is plugged in. The Streaming indicator will light up when audio is actively passing over USB. Please note that we have observed instances with PC based hard CODECs (such as Vidyo) where the Streaming indicator of the USB Tx block would only illuminate when the CODEC was in an active call. Zoom PC's can optionally be controlled by a third party iPad app or control system. In our experience, users may need to select the Tesira USB peripheral from the iPad app to enable functionality.
Channel Settings
Once connected, the Tesira USB device will show up in the Sound control panel in Windows. You can access the Sound control panel by going to the Windows Start menu→Control Panel→Hardware and Sound→Sound . Alternately, you can also right-click on the Windows sound icon (bottom left on the task bar) and select 'Playback Devices' or 'Recording Devices'.
Depending on how the USB Input/Output blocks were configured, the Tesira USB device will show up as a Playback device, a Recording device, or both. It may present itself as a 'Line' or a 'Speakerphone' device.
The Tesira USB device presents itself under Playback similar to this example below. Clicking the Properties button will allow access to level settings and other advanced options.
Installing Biamp USB Driver for Windows multi-channel recording
By default, Windows cannot handle a USB audio device that uses more than two audio channels. Therefore, in order to send more than two audio signals third-party software is required to make the additional channels available. Biamp has released the Biamp Tesira USB Driver for Windows to support multi-channel audio.
Download and install the Biamp Tesira USB Driver for Windows. Once installed you will see the Biamp Tesira Control Panel icon in the task bar:
Open the Biamp Tesira Control Panel, you will see the Biamp Tesira USB device connected that will be presented as the 'Biamp Tesira - ASIO' device.
Example of the Biamp EX-UBT AVB expander:
Example of the Biamp TesiraFORTÉ USB:
Example of multiple Biamp Tesira USB devices connected at once. Note you can only select one device at a time.
Note that the Biamp driver will only work with compatible software, and Windows will continue to show only a 2 channel Stereo input and output Tesira USB device.

- All versions of Windows 10/7/8 work with our driver. The exception is with the first version of Windows 7 a Microsoft hotfix must be installed to accept our SHA256 signed driver. Further details can be found online within Thesycon's FAQ section.
Troubleshooting multi-channel audio
Drivers Data Card Port Devices Replicator
- When connected (/disconnected) to (/from) a PC the USB device should be added (/deleted) in Windows PC Device Manager's Universal Serial Bus controllers list (as a USB Composite Device) as well as the Audio inputs and outputs list in real time.
- The Biamp Tesira Control Panel for the Biamp ASIO driver (in the Windows tray) allows you to select the ASIO buffer size. A larger buffer will increase latency to the USB recorder but will reduce load on the CPU. Larger buffer sizes may reduce clicks, pops, glitches, or dropouts.
- When verifying USB output to computers it can be useful to route a tone generator to the USB output channels. A 1kHz tone at +12dBu routed to each USB output channel will clearly show activity on meters on the recording PC. On some recording platforms the meters may not indicate low 'background level' activity so providing a high-level slate tone allows easy and repeatable validation of connected channels. Note that a +12dBu signal from the Tesira tone generator to a USB meter should indicate about -12dBFS.
- 3rd party audio metering software can be used to independently verify the USB audio input if there is a question of the customer's recording software accurately receiving input. Be certain the 3rd party software is configured for the correct number of channels, the correct sample rate, and is assigned to monitor the correct USB inputs. Options that have been seen to work in the past include:
- https://pas-products.com/multimeterbridge.html
- Under Settings > 'Select audio input' choose '8 channels'
- Under Settings > 'Level Outfit' - Meter Ballistics options choose 'Peak dBFS'
- https://www.orban.com/meter
- In the Settings tab choose Channels = '7.1 Surround' and the desired Audio Device input channels
- In the Meters tab be sure to Start metering using the button at the bottom center
