| Content | The BIAMP MDS microphone discussion system is a highly flexible small to medium size tabletop discussion system. This easy to set up and to easy to use audio system is the perfect solution for meeting rooms, board rooms and medium conference rooms. This discussion system consists of a chairman unit (MDS.CHAIR) and up to 19 delegate units (MDS.DEL). The connection interface (MDS.INT) is located at the beginning of the microphone chain.
This MDS system has a unique circuit loop design with an easy set-up using standard CAT5 cables for linking up to 20 units in a daisy chain (every microphone and switching adaptor can be located anywhere in the loop). When the chairman presses the mute button, only the chairman unit will be active and all delegates will be muted and deactivated. The delegates can press a button to talk into the flexible gooseneck microphone (no mute function).
The MDS.INT easily connects to any pre-amplifier or matrix with a MIC input with wide gain control (about +20dB of gain needed), allowing you to control the volume and/or use the record output for recording the meeting. Combined with the CMX20T ceiling speakers or MASK4 cabinet loudspeakers, you will have an astonishing voice clarity! |
- 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.

- 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.
