Bosch CCS 800 Ultro Discussion system

The Bosch CCS 800 Discussion system is a versatile, economical discussion system intended for small-scale meetings and gatherings. It provides all of the facilities required to control meetings and discussions, and allows delegates to communicate with each other by means of microphones and built in loudspeakers or personal headphones.

It is intended for venues such as local government councils, hotel function rooms, magistrates, company board rooms and conference centre breakout rooms.


The Philips / Bosch CCS 800 system comprises: a central control unit, chairman unit, delegate units, and interface to PA or Infrared Red wireless distribution system. A single control unit (SPSU) can connect up to 50 contribution units but can be expanded to 100 contribution units.

The Bosch CPSU forms the heart of the system, and controls the microphones of the chairman and delegate units, as well as providing connections for audio inputs and outputs to PA and Infrared wireless language systems. It provides the power for all of the delegate and chairman units. A single CPSU has a maximum capacity of 50 contribution units, but the system can be expanded to 100 contribution units by the connection of a second CPSU and an interconnection cable. A third CPSU can be connected for a maximum 150 delegates. The CPSU can be mounted in a 19" rack with the optional mounting brackets.
The Bosch CCS800 discussion system is quick and easy to install, and requires no special training. Each contribution unit is fitted with a 2m cable terminated with a plug, and a socket. The units are simply plugged into each other in a daisy chain configuration, with the first unit connected to one of the two CPSU trunk outputs. Twenty-five units can be connected to each of the two trunks making a maximum configuration of 50 units per CPSU.

An external condenser microphone can be connected to the Bosch CPSU. A collapsible floor stand and adjustable boom can be used together with a 10m 3-pole XLR extension cable for quest speakers or audience participation.
There are two kinds of contribution units for the CCS800 discussion system, chairman units and delegate units. Both are available with either a standard microphone stem (313mm) or an extended microphone stem (488mm).
Delegate units enable delegates to speak and listen to the proceedings via a loudspeaker or headphones. The stylish and ergonomically designed unit includes a microphone with a red indicator ring which illuminates when the microphone is on. To prevent feedback, the built in loudspeaker is muted when the microphone is on. Two 3.5mm stereo headphone sockets (wired for mono) allow two pairs of headphones so two delegates can simultaneously use the unit. The headphone volume level can be adjusted on the unit for maximum comfort. It is also possible to connect a tape recorder to one headphone socket, and use the other headphone socket to listen to the proceedings. The chairman unit is similar to the delegate, but also includes a 'chairman priority' button.

The transport and storage cases are used in applications where the Philips / Bosch CCS800 contributions units will not be used in one fixed location, and therefore has to be easily transportable. This is often the case for town halls, hotels, local government offices, business centres, or smaller halls in major conference venues.

Two transport and storage cases are available:

LBB 3312/00 - This storage case is designed to accommodate 10 contribution units.

LBB 3312/10 - This storage case is designed to accommodate 6 contribution units and the CPSU (Central Power and Control Unit).


Extension cables of 5m (LBB 3316/05) and 10m (LBB 3316/10) are available to give additional flexibility in larger application sites. The cables are terminated at both ends with moulded 7-pole DIN connectors (male and female).

A 100m installation cable (LBB 3316/00) is also available with 5 connector sets so that cables can be made to specific lengths on-site by an engineer.

A set of locking clamps (LBB 3517/00) contains 25 clamps for extension cables. One clamp per male/female connector is required.
