  Functions

  Discussion control

  Bosch CCSE-CU-CCS700 Conference Control unit supports almost any kind of small or medium meeting. For business discussions and small conferences, two to six microphones can be active simultaneously, with the chairman always having speaker priority. The active microphone selection knob on the rear panel can be used to select the number of active participants. Unused microphones are switched off automatically after 65 seconds if delegates forget to switch off their units.

  Supplies power for up to 50 Discussion units
  The CU has two trunk outputs for the loop through connection of discussion units. It is possible to connect a maximum of 25 discussion units to each trunk output in open loop configuration. Maximum trunk length supported by CU is 100m in open loop configuration. For closed loop configuration with 50 discussion units the loop length can be extended up to 200meter. A maximum of 50 discussion units can be connected to a CU.

  Better sound
  The conference controller has a 3-band equalizer for tuning sound output of the system. This helps in quickly tuning the system to compliment the hall acoustics at different venues. This ensures optimum performance at all times.

  Audio Interfaces
  The CU can be interfaced with different type of devices like external audio recorder, sound reinforcement system, external microphones and external music player. The headphone output on the front of the CU can be used by a secretary for taking the minutes of the meeting, the headphone output also has a volume control knob to adjust the volume of the headphone. To support external participants (during town-council meetings, for example), extra microphones in any style (wired, wireless, handheld or podium) can be connected to the system through mic inputs
