Beam Settings - Audio Technica ATND1061LK Operation Manual

Beam settings

Accurately setting the microphone coverage range
Internally, the microphone estimates the position of the talker with angle information in the horizontal and vertical directions.
It is difficult to determine the position of the talker with just this angle information, so the polar coordinates are projected
onto a plane, and the settings are configured on a plane that cuts the "Current View Level" height. Digital Microphone
Manager allows for the importing of image data, so a more accurate microphone coverage range can be set with the
position and height of the target sound source.
Microphone coverage settings
There are two types of Zone settings in the microphone coverage settings: Coverage Zone and Priority Zone. By default,
the microphone has a Coverage Zone of 6 m × 7 m (20' × 23') at a height of 1 m (3.3'). The ATND1061 is equipped with a
high-speed talker detection function, so you can obtain smooth microphone coverage just by setting the Coverage Zone.
Splitting off channels or adjusting the gain for simultaneous speech
With the Coverage Zone setting, one beam is assigned to each channel, so if simultaneous speech occurs, the channel
with the higher level is recognized as the talker. The Priority Zone setting allows you to split off a channel for the MC or a
person serving a similar role and to split off channels for talkers with different levels and adjust the gain.
• You can overlap Coverage Zone and Priority Zone instances, but you cannot overlap Priority Zone instances.
• If a Coverage Zone instance and a Priority Zone instance overlap, sound normally only comes out from the channels
to which Priority Zone has been assigned.
• If you select the "Include in Coverage Zone" check box, audio will be output from the channels to which Priority Zone
has been assigned as well as from CH1 to which Coverage Zone has been assigned.
