Functions
General
• Single‑use and chairperson can be configured via the PC configuration software application.
• Five touch buttons to support electronic voting:
– Present button
– For
– Against
– Abstain
– DNPV
• Built‑in Near Field Communication (NFC) contactless tag reader.
• Additional functionality by use of software licenses only:
– Identification functionality.
• Audio mute button.
• Supports star and loop-through connection.
Speech intelligibility
• Crystal‑clear sound due to a very high signal‑to‑noise ratio.
• Maximum speech intelligibility is guaranteed.
• The loudspeaker and microphone can be active at the same time to facilitate a face‑to‑face meeting experience. A feedback suppressor is built in to prevent acoustic feedback.
Security
• Encryption ensures that information within the system remains confidential
Microphones
• A socket is provided to connect the pluggable microphones DCNM‑HDMIC, DCNM‑MICS or DCNM‑MICL (to be ordered separately).
Headphones and loudspeakers
The device has a headphone connection and independent volume control (on both sides of the device), so the speaker can be heard clearly even when there is excessive background noise.
