BOSCH DCNM-DVT Discussion Device with Voting

DICENTIS incorporates several standardized technologies that have been combined to create an open platform. Complete system solutions can be created by simply integrating compatible products. This makes DICENTIS extremely scalable, enabling it to evolve with the growing needs of meeting and conference facilities. At its heart, the DICENTIS Conference System makes use of the unique IP based OMNEO media networking architecture, developed by Bosch.

The elegantly designed DICENTIS Discussion devices enable participants to speak, register a request to speak and listen to discussion. The DICENTIS Discussion device with voting incorporates standard parliamentary-style voting. To enable the participant to fully concentrate on the discussion, the voting touch-buttons only light up when voting is available. The DICENTIS Discussion device with voting also supports fast participant recognition via NFC tag identification.

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.

Controls and Indicators
• Top side of device:
• Five touch buttons
• NFC identification reader
• Microphone with a red or green indicator:
• Red indicates that the microphone is active.
• Green indicates that a request-to-speak is accepted.
• LED indicators on device showing:
• Microphone on state Red.
