The Control and Power Supply Unit (CPSU) is the heart of a discussion system. This versatile unit incorporates a digital acoustic feedback suppression facility, which allows any acoustic feedback (also known as “howling”) to be automatically eliminated.
Other included features are: managing the number of active microphones and determining the operating mode, without the need for a central operator. External equipment can be connected to extend system possibilities. A built-in loudspeaker allows the conference to be monitored (to allow a stenographer, for example, to take notes on the conference).
Discussion control without operatorThe CU can be setup to operate standalone without the need for an operator. The following 5 modes can be chosen using a rotary control on the unit’s top panel:
Supplies power for up to 50 contribution unitsThe CU has two trunk outputs for the loop-through connection of contribution units. It is possible to connect 25 contribution units to each trunk output, with a maximum system cable length of 100 m (109.3 yards).
Provides control for up to 150 contribution unitsUp to 3 CUs can be used together in a discussion system to power and control a maximum of 150 contribution units. In this configuration a single CU acts as a master controller for the entire system.
Built-in monitor loudspeakerThe built-in monitor loudspeaker and headphone socket allow the conference to be monitored.
Interfaces the system with external equipmentThe following equipment can be interfaced to the CCS 900 Ultro Discussion System through the CU:

CCS-CURD Control and Power Supply Unit with Recorder & Digital Acoustic Feedback Suppression
The Control Unit (CU) is the heart of the CCS 900 Ultro Discussion System and supplies the power for all delegate and chairman units in the system. The unit also controls the chairman and delegate unit microphones, as well as providing connections for audio inputs and outputs.
Built-in MP3 recording and playback with graphical display
The CU has a built-in recorder to digitally record a discussion to an SD Card. The graphical display shows the status of the recorder and the accompanying buttons can be used to configure the recorder. As an option, the recording is only active when a microphone is active. The SD card can be removed from the CU and processed on a PC for transcription purposes; the recordings can also be retrieved by connecting a PC to the CU’s USB. The recordings can be played back to the monitor loudspeaker or to delegate’s loudspeakers. An audible beep and a flashing LED indicate when the SD Card is almost full andthe user needs to replace it with a new card.
Patent-pending recording buffer
A card can be replaced by an empty card while recording is running. When the full card is removed, the recording is continued to a patent-pending recording buffer. When a new card is inserted into the CU, the buffered recording is written onto the new card and the recording continues normally. This gives seamless recording without the loss of any audio while an SD Card is exchanged.Digital acoustic feedback suppressionThe digital acoustic feedback suppression facility automatically eliminates acoustic feedback (also known as ‘howling’ or ‘Larson effect’). This gives better speech intelligibility by allowing the speaker volume to be turned up as loud as required without any risk of feedback.
Discussion control without operator
The CU can be setup to operate standalone without the need for an operator. The following 5 modes can be chosen using a rotary control on the unit’s top panel:
