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

- Base Station for up to 200 Microphone Stations
- Intuitive controls
- Superior audio quality
- Voice activation and NOM limitation
- Standard ins and outs for external equipment
The CS 2 Base Station controls up to 200 Microphone Stations and provides automatic NOM (Number of Open Microphones) attenuation. System gain will decrease by approx. 3 dB every time the number of open microphone doubles. The result is a substantially lower risk of feedback even if the number of open microphones varies constantly.
A selectable Voice Activation function turns the microphones on automatically as soon as they are talked into.
The NOM Limitation function allows the number of simultaneously open microphones to be limited to one, two, three, four, or five. This function can be locally disabled on each Microphone Station so a specific microphone, e.g., one mounted on a lectern, will come on every time, no matter how many mics may be open already. |
- System Features and Outline
- Bilingual conference system. Either English interpretation (main audio) or Japanese interpretation (sub audio) is selectable for monitoring.
- Operations such as giving speech permission can be done from the operation PC. *Custom design.
- The number of conference units can be set for any of one, two or four persons allowed to talk at a time.
- All speeches during the conference can be recorded clearly.
- Sub audio(Japanese interpretation) is not recorded.
- Threefold choice vote function enables the voting just at the press of a Vote key on each unit. The result can be instantly totalized on the Central unit.
- Speeches can be addressed to audience via sound amplification. * The sub audio output is not amplified

- Digital controller for any size systems
- Ease of use
- Complete with all inputs and outputs needed for complex systems
- Integrated infrared signal output
- Free basic control software included
The CS 5 BU ensures easy, user-friendly control of everything from a small discussion setup to a large conference system. The Base Unit provides all the inputs and outputs needed to manage a complex audio system. It controls 64 audio channels that can be individually programmed and assigned to interpretation channels or NOM limitation.
To ensure maximum reliability, all microphone stations and interpreter stations are „daisy-chained" together and connected back to the Base Unit, forming a closedcircuit digital audio bus. Thus, the entire system will continue operating perfectly, with no interruption, even if one of the bus cables breaks.
To power the system, a CS 5 PS 12 power supply is connected to every twelfth microphone station, ensuring consistent signal levels. Unlike competitive techniques, AKGʼs approach to keeping consistent signal levels throughout the system is uncommonly cost efficient. Every CS 5 Conference System comes complete with a FREE basic control software package so the entire system can be controlled from a computer from day one.
The Base unit shall operate up to 5000 units. As analogue inputs the base unit shall handle an external microphone for easy translating to be routed to channel 1, an ordinary external microphone, telephone in and out with mix minus sum, tape in and out and Line in and out. The infrared modulation shall be included in the base unit, providing the relevant infrared signal on two BNC connectors. Also included in the base unit shall be a USB connector to connect to a PC. A basic software package for participants database, voting and other basic functions shall be included. The unit shall be 1 HU 19” wide in a rack mount housing. A serial port shall be available to enable AMX control.
