Phoenix Audio Spider USB and SIP/IP Telephone MT505 - Manual (Page 6)

DURING A CALL
DIRECTIONAL ARRAY
During a call the Spider uses proprietary beamforming technology to locate a legitimate voice
source and steer an array towards it. This allows the Spider to focus on the speaker in the room
and to cancel out all other noises.
The beamforming process is dynamic and adjusts the direction of the array when the source of
sound changes or moves. When in a call and voice is detected in the room, a single or multiple
blue lights located under the grill will indicate which direction the Spider’s audio beam is
focusing on. This is the direction that will be heard best by the far-end of the call (the person you
are talking to).
NOTE: This function can be disabled (see page 9).
