Application Guide ES-1 Audio System Set-up Guide for Microsoft Teams After selecting the audio device in the Microsoft Teams Room settings, the MTR uses USB Human Interface Device (HID) signaling to proxy call status and controls to the processor. HID functions are always active in the MTR and in the EX-440C. HID synchronizes the call status and microphone privacy state with the LEDs on the TCC2. Privacy Mic Mute status and Call Status are synchronized through the EX-440C USB Out block.

Application Guide ES-1 Audio System Set-up Guide for Microsoft Teams Figure 17: Properties window Figure 18: Control Cockpit interface Levelling the TCC2 Beam Freeze The far-end signal (the signal received from the far-end presenter) can be routed from the DSP to the TCC2 AEC Ref input via Dante. This AEC reference signal is used inside the TCC2 to steer the beam into a static status (at 315° horizontally and 90° vertically) at any time when the far-end presenter is active.
Application Guide ES-1 Audio System Set-up Guide for Microsoft Teams Finding the Correct Level for the AEC Ref Signal Set up a test call where the far-end presenter is unmuted but remains quiet. In the control software for the AEC, set the output level for the AEC ref signal to the minimum level. This allows the position of the near-end presenter to be tracked properly, never reaching the Static status.
Application Guide ES-1 Audio System Set-up Guide for Microsoft Teams Troubleshooting and Commissioning Guide The TCC2 does not connect.
