Application Note for TesiraFORTÉ TeamConnect Ceiling 2 In order to improve the AEC-performance of the overall conference setup it is advisable to provide the AEC-reference signal (i.e. as being played back by the loudspeakers) to the TeamConnect Ceiling 2's reference-input-channel (1st Dante input-channel), so the beam-steering can be stabilized during far end speech. Use the Dante-Controller-Software on a computer attached to the Dante network to establish the routing between the respective Dante-endpoints. Leveling of the AEC-reference: The far-end signal (receive signal from the far end talker) needs to be routed from the DSP to the TeamConnect Ceiling 2 AEC Ref input via Dante. This AEC reference signal is used inside the TeamConnect Ceiling 2 to steer the beam into a static status (at 315° horizontally and 90° vertically) at any time when the far-end talker is active. The static status is enabled when the level of the AEC reference signal exceeds a certain threshold. In order to ensure appropriate functionality of this feature, it is crucial to adjust the level of the AEC reference signal. Optimally, the level of the AEC reference signal should be adjusted in such a way that the static status is not active when the far end talker is not active. Proposed procedure to find the right level for the AEC ref signal: Setup a test-call where the far-end talker is unmuted but remains quiet. Set the output level for the AEC ref-signal inside the control software for the AEC to minimum. In this way the position of the near-end talker should be tracked properly, never reaching the static status. The static status is indicated in Sennheiser Control Cockpit by a direction of 315° horizontally and 90° vertically. When the output level of the AEC reference signal is increased steadily, at a certain point the static status becomes active and the displayed position in Sennheiser Control Cockpit is stuck to 315° horizontally and 90° vertically. Find the level where the static status is starting to be active with a quiet farend. When this threshold is found, reduce the output level of the AEC reference signal by 15-20 dB. AN 1255 v1.0 | 9/11
