We have developed the U500® in Germany to meet all of your requirements of a wireless conference system. It offers a professionally equipped solution for effective communication and interaction with advanced technology, excellent speech intelligibility and an elegant appearance. The user-friendly True Diversity UHF system with 60 channels in 6 groups facilitates easier installations and turns conferences, meetings and round tables into successful events.
The U500® terminals feature a gooseneck condenser microphone with hyper-cardioid characteristic and a light ring to display status. The heavy table stand features an XLR microphone input, 28 V phantom power, an on-off-mute switch, as well as a gain control and a selectable 130 Hz high-pass filter to effectively reduce proximity effect and structure-borne sound. A high-contrast OLED display shows radio frequency, battery status, terminal number, group and channel. The audio transmission range is 60 Hz - 16 kHz.
For simple, fast configuration, the 4-channel U500® conference system receiver features automatic frequency and channel scanning, infrared synchronisation, a digital encoder and 4 buttons to directly access the individual channels. The high-contrast OLED display provides a comprehensive overview of all functions and settings such as audio and radio signal strength, and priority and battery status of the terminals. The number of simultaneously-live microphones can be configured in order to eliminate crosstalk, feedback and comb filter effects. Selectable automatic or manual gate settings and a pilot tone ensure that the U500® conference system delivers superb sound quality with excellent noise immunity. In addition to its individual channel outputs, the receiver also has a master output, an access lock to prevent unauthorised adjustment of settings, and the RS-232 interface to facilitate integration into external control systems.
For system expansion, up to five U500® receivers can be cascaded and used in master-slave mode, making a maximum of 20 terminals possible. The U500® conference system is available in three versions which work in the following frequency areas: 554 - 586 MHz, 662 - 694 MHz or 823 - 832 MHz + 863 - 865 MHz

- Choice of microphones for every kind of system and room acoustics.
- Display and multifunction soft keys for ease of use.
- Up to 63 language channels independently selectable for two users.
- 1, 3, 5-way voting/polling function.
- Dip-switch selectable president and delegate operating modes.
The CS 5 VU provides two operating modes, reducing the number of different components needed for a conference system.
In a small discussion system with CS 5 DU microphone stations, the chairperson would typically use a CS 5 VU. In President mode, it provides a priority function and allows the user to start votes or polls. The display will then indicate the time left for voting and the results.
In a larger conference system, the CS 5 VU can be used both by delegates and by the president. In delegate mode, it provides all voting and language selection functions independently for two delegates. A bank of dip switches allows the CS 5 VU to be set to President mode with priority and 1, 3, or 5-way voting/polling functions. In computer-controlled conference systems, chip-card identification is available as an option.
Gooseneck, capsule and connecting cable are not included.
The unit shall act as chairman unit or normal delegate unit, selectable by a dipswitch on the bottom of the housing. It shall have a built-in microphone and loudspeaker, which allow the forwarding of the voice of the speaker towards the other units of the system. The chairman shall always be able to start 1,3 and 5 step voting from the unit and monitor the results on the unitʼs display. Priority calls shall also be possible from his unit.
The CS 5 VU is suitable for taking over maximum 63 interpreted languages and the room voice as well, which may be listened to through the headset that is connected to the device. A chip card reader is also included in the unit, with the aid of which it is possible to identify the user of the device in the case of a computer controlled conference.
The backlit graphic LC display facilitates using the device and displays its current status and the result of the vote. The unit shall operate for 2 persons simultaneously, with independent adjustable languages for each of the 2 x 3,5mm stereo jack headphone sockets.
