VISSONIC VIS-DAC-T

Description

The horizontal arrangement of the microphone array creates a vertical corridor characteristic. This allows great freedom of movement for the user - whether sitting or standing - volume and sound quality remain the same. People to the left and right of the speaker are hidden.

Features

• Solid, unobtrusive design with touch buttons.
• Simple, intuitive operation.
• The ARRA-Tech microphone array Technology enables a speaking distance of up to 80 cm with easily understandable voice transmission.
• Standard CAT5e cabling with RJ45 connectors makes setup easier and offers a secure connection.
• The call station has a permanently connected CAT5 cable with RJ45 Plug. Two microphone stations are always connected via a VIS-CNB splitter box. This reduces the number of cables on the conference table.
• The array conference stations do not have a built-in speaker.
• A headphone jack with an easily accessible 3.5 mm mini-jack headphone output on the side.
• AUDIO-LINK technology with a ring-shaped network guarantees good signal transmission and prevents interference from external transmission sources such as smartphones or similar devices.
• VIP delegate: If all microphone stations are designed as “presidential microphone stations”, up to 32 of these microphone stations can be used as Define VIP delegates, i.e. up to 8 of these conference stations can assign themselves at any time at the same time.
• A CAT5e network cable transmits 64 audio channels and additional control information.
• Very good sound quality, interference-free signal transmission, 48K sampling rate and a frequency response from 20 Hz to 20 kHz.
• Functional modes of the call stations:
- "OPEN" mode: Each call station is activated as soon as the talk button on the call station is pressed.
- "APPLY" mode: At Pressing the talk button on a call station initiates an activation request. The microphone on the call station lights up green and the presidential call station indicates that there is an activation request. The President can accept or reject them. If the President accepts the activation request, the microphone of the affected station lights up red and the microphone is active.
- "VOICE" Mode: As soon as a station is spoken loudly enough, the microphone is activated.
- "OVERRIDE " Mode: When you press the talk button on a call station, the microphone is activated. At the same time, the previously active call station is deactivated.
• The VIS-DCP2000-R control center must be used to operate the array call stations.
• IEC 60914 and GBT 15381-94 standards compliant.
