Bosch CCS 900S Ultro Conference System Microphone

The CCS 900 Ultro Discussion System offers new design features and extra functions, including a patent-pending “Possible-To-Speak” indication. Designed and developed by Bosch experts in Europe, the system makes it easy to manage meetings and lets users record the proceedings digitally, via


A compact, full-featured meeting solution
Each system includes a control unit (CU) connected to a number of delegate and chairman units. The advanced CU is equipped with a recording, an easy-to-read LCD screen and a Secure Digital (SD) card slot for recording.

Innovative and authentic design
The CCS 900 Ultro Discussion Unit delivers excellent ergonomics, improved acoustical characteristics and a design that complements any interior, from new, ultra-modern buildings to traditional, centuries-old structures. It combines excellent acoustics, superior component design and intuitive use with eye-catching aesthetic quality.

Unique, patent-pending “Possible-To-Speak” indicator
The “Possible-To-Speak” indicator gives delegates a visual indication when the microphone is available to speak. Depending on the selected mode of the CU, up to four delegates can switch on their microphones simultaneously. During the meeting, the “Possible-To-Speak” indication on each delegate unit displays one of three options: red, white or off.

Excellent speech intelligibility with acoustic feedback suppression
Use of genuine Bosch DAFS (Digital Acoustic Feedback Suppressor) ensures superb speech intelligibility. The technology employs proprietary DSP (Digital Signal Processing) functions to balance sound pressure levels and system gain above normal feedback limits. As a result, users can increase the volume to higher-than-normal levels without generating feedback or making the microphone "howl".

Complete discussion control
The CCS 900 Ultro lets the chairman manage and record the proceedings. The chairman unit has a priority button with attention tone to mute delegate microphones. Additional microphones and other equipment can be added as well.

Plug-and-play discussion system
Since it’s a plug-and-play, all-in-one discussion solution, the CCS 900 Ultro requires no special training or operator. Anyone can begin using the intuitive controls immediately. The display on the CU is language-independent, and the microphone mode and the volume level can be adjusted using the CU dials.

Built-in digital (MP3) recording and playback stored on removable SD cards
The chairman can digitally record and playback up to 64 hours of discussion using a 2 GB SD card. When it’s time to insert a new SD card, the patent-pending recording buffer stores the ongoing discussion for up to 60 seconds, so there’s no loss of data while changing cards. The CCS 900 Ultro provides several options for playback, including previously recorded segments, background music or pre-recorded messages and speeches.

Future-proof system expandability
Value-added features, an elegant design, an excellent price/quality ratio and innovative technology make the CCS 900 Ultro system exceptional. The system is designed for future expansion, with the possibility of adding a wide range of additional equipment and auxiliary components, including an interpretation system, language distribution, public address system and an interface for tele/video conferencing.


The ideal discussion solution…
The CCS 900 Ultro Discussion System is ideal for small-to-medium-scale meeting areas, such as town halls, local business centers and courtrooms. The CCS 900 Ultro is a flexible solution for this type of venues and makes it easy to conduct meetings without an operator. The chairman can guide the discussion, allowing individual delegates to speak or letting several delegates take the microphone simultaneously. Delegates are guided by a visual LED to know when to speak.

…with room to grow
The CCS 900 Ultro Discussion System makes an excellent base installation for medium-scaled applications such as international business and conference centers. It can easily record an entire conference or event for accurate archival or publication. It is easily integrated with the Bosch Integrus Digital Infrared Language Distribution System.
There are a variety of integration possibilities, like a Bosch handheld microphone to speak or give presentations. Using an interface for tele- and video conferencing, two remote locations can be connected with each other.
