- Page 2 Introduction This guide explains the guidelines for installing and configuring the ATND1061. Specifically, the items covered are as follows. • Features • Room in which to install the product • Microphone coverage range • Beam settings • Camera linking • Microphone placement and setup examples...
- Page 3 Features Optimal operating environment The ATND1061 is the optimal solution for large and small conference rooms, boardrooms, and meeting spaces. It can also be used as the optimal solution for classrooms, multipurpose rooms, and other such rooms in the educational field. On the other hand, note that the functions and features of the ATND1061 cannot be used to their full extent outdoors and in cases where sound reinforcement is used.
- Page 4 To eliminate the disadvantages of the talker-tracking method, it is necessary to improve tracking accuracy and speed. The classical method conventionally used to detect the audio direction is to search for the direction with the highest power and define this as the direction where the talker is located. With this method, the tracking accuracy can be improved by averaging the signals received by the microphone over a long period of time, but the difficulty in aiming the beam in different directions at high speed results in insufficient speed for practical applications.
- Page 5 Room in which to install the product Room size and number of microphones to install For microphone coverage in rooms such as huddle rooms and conference rooms, consider installing one microphone per 70 m (753 ft ) as a guideline. •...
- Page 6 Audio reflection level Rooms with few audio reflections tend to have clearer audio and allow for the talker to be detected with higher accuracy. Rooms with a reverberation time of approximately 700 msec (RT60) are permissible, but use in rooms with longer reverberation times is not recommended.
- Page 7 Microphone coverage range Talker detection range The ATND1061 can detect the talker within a circle with a radius of up to approximately 5 m (16’) centered on the microphone (assuming an environment with few audio reflections). In Digital Microphone Manager, the positions indicated by this 5 m (16’) radius are shown with the device color (green by default), providing a guide for setting the microphone coverage range.

Page 8: Beam Settings
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”... - Page 9 • The Coverage Zone and Priority Zone can also be used as six independent channels. • A wide range of applications is available. For example, in a classroom where there is a teacher and Note students, the Coverage Zone, which provides microphone coverage over a wide range that includes the students, is sent to the recorder, and the Priority Zone sounds are mixed and sent to the far end.
- Page 10 Camera linking The ATND1061 outputs the talker position information with the IP command. This operation is useful as the trigger for recalling camera presets. The IP command includes the following information: whether there is a talker, the direction of the talker, the audio channel number, and the camera zone number.
- Page 11 Microphone placement and setup examples This section explains the optimal microphone placement and setup for detailed room sizes. Huddle room / small conference room (24 m [258 ft Microphone count: 1 Well-balanced microphone coverage is possible with operation that only uses Coverage.
- Page 12 Medium conference room (common boardroom layout; 64.4 m [693 ft Microphone count: 1 Operation that only uses Coverage is acceptable, but channels are split off in this example to support simultaneous speech and level differences between talkers. The channels can also be sent to a mixer for DSP processing.
- Page 13 Medium to large conference room (operation with 2 microphones; 84 m [904 ft Microphone count: 2 Zones are created to match the placement of tables. The auto mix function and the gain sharing function among multiple devices allow for signal transmission with stable levels.
- Page 14 Multipurpose space (153.6 m [1653 ft Microphone count: 2 In this example, separate channels are output individually in the front presentation space.
- Page 15 Classroom / lecture hall (203.5 m [2190 ft Microphone count: 4 In this example, the oblong shape of the front presentation area is handled by splitting it into two sections, each with its own microphone.
