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 2 (753 ft 2 ) as a guideline.
• The conditions vary depending on the installation height of the microphone, the shape of the room, and the intensity
of audio reflections and the voice of the talker.
• Operation linked with a camera and talker position detection both require higher accuracy in the detection of the talker,
so it is recommended to install one microphone per 50 m
Installing multiple ATND1061 units
Install multiple microphones in wide rooms, large conference rooms, and similar situations. Up to 20 devices can be
handled per Digital Microphone Manager project. It is also possible to import drawings, so consider an installation that
matches the layout of the room.
Recommended room conditions
Noise level
Generally, the noise level in conference rooms is 40 to 50 dB. The ATND1061 is designed for ideal performance at this and
lower levels. If you are concerned about steady state noise, use the built-in noise-cancelling function or the same function
of an external DSP.
Notes related to air conditioners
One of the major features of ceiling microphones is that they can capture clear audio even when installed in a ceiling.
However, exercise caution to avoid positioning the microphone right next to an air conditioner or in a location where it is
directly subjected to air blown from an air conditioner. Because of the distance from the microphone to the talker, audio
signals will attenuate before reaching the microphone, making the talker's voice quiet. Hence, the intended sounds to pick
up may be covered by noise, which is louder due to its proximity to the microphone.
