Notice the sound device name also includes the unique serial number of the EX-UBT device by default. When the EX-UBT is connected to a host computer, it will enumerate as an Echo Cancelling Speakerphone or sound device as defined during block initialization. Balance controls will not be synchronized between the USB input block and the USB host when in speakerphone mode (only playback levels are).In Multi-Channel 8x8 Line In/Out mode, changes to the USB host mute and record level controls will be ignored by the EX-UBT."USB host" refers to USB on the computer.It is also checked by default if the Line In/Out USB terminal type is selected. This selection is checked and cannot be deselected if either of the Speakerphone USB terminal types is selected. Mute USB outputs as a group - Selecting this mutes all USB output channels when the mute state of a single output channel is changed. Mute USB inputs as a group - Selecting this mutes all USB input channels when the mute state of a single input channel is changed. Combinations of 2, 4, 6 or 8 total USB channels can operate in fixed 24 Bit, 48 kHz. Line In/Out – This mode provides up to eight channels of audio. Speakerphone: Enables Computer AEC – This mode is for situations where the soft codec will provide the AEC function. A control message is transmitted to the soft codec via the USB link telling it to disable its internal AEC. Speakerphone: Disables Computer AEC – In this mode, the Acoustic Echo Cancellation (AEC) function will be provided by the AEC block in the Tesira DSP. The USB Input represents the incoming audio from the soft codec, and the USB Output is used to send audio to the far side. USB Connection Type - The two Speakerphone modes provide single or stereo audio input and output streams for use with a soft codec application on a host computer. Multi-channel 8 input channels x 8 output channels.Stereo 2 input channels x 2 output channels.USB Channel Count - This allows the user to select between three different channel configurations: Users may check to use USB, Bluetooth or both. When the Tesira EX-UBT object type is selected from the Audio Object Toolbar, the EX-UBT Initialization dialog window is displayed: Disabling the feature in the Advanced options of the Speakerphone audio settings resolves the issue.Ĭonfigurations for the Tesira EX-UBT are available from the Object Toolbar via the Telephony/Communications menu item: This has been seen to be detrimental to USB audio resulting in added noise and very low transmit levels. This can be viewed in Windows audio device settings or similar of the host device:Ī Windows 10 update has added a Speakerphone audio signal enhancement feature which is enabled by default. Tesira FW 4.0.3 and newer will auto-negotiate with the host UC/PC device for the proper format. Some devices prefer 16 bit over 24 bit audio formatting. ![]() This list is inclusive of formal support and interoperability other devices and platforms not in this list may honor HID mute synchronization. HID mute synchronization and AEC offloading are supported by various UC platforms and detailed further in our Biamp UC Compatibility article. When configured as a speakerphone, the EX-UBT uses Human Interface Device (HID) communication that can synchronize privacy mute state and volume control if the UC application supports this communication. For 8-channel playback the '7.1 Surround' is the correct option, ensure all speakers are selected and that the full-range option is enabled for all channels. Ensure that the correct audio channel mode is selected. In Windows' Sound settings, select the desired Tesira USB playback device and choose 'Configure'. ![]() Windows can only support mono and stereo audio natively without needing to install a USB driver. Be sure that your PC has the latest Biamp ASIO driver installed. ![]() Mac OS supports multi-channel audio natively. Note that the Biamp Tesira USB ASIO audio driver is required for Windows OS when using multi-channel mode.Within Tesira software, the USB can be configured to pass audio in/out according to one of the following options: The EX-UBT USB port acts as a client to the connected host computer.
