Running a conference The volume of the conference units' loudspeakers can also be set via the central unit's operating menu (see page 56) or the "Conference Manager" software (see page 130). Use the "Feedback Suppression" function to be able to increase the floor channel volume by up to 5 dB without feedback occurring (see page 57 or page 132). Muting the conference units' loudspeakers for contributions coming from the conference units' microphones The "Mic Loudspeaker Mute" function allows you to mute the conference units' loudspeakers so that contributions coming from the conference units' microphones are not reproduced (see page 58 or page 131). Adding conference units to the conference system during operation You can add conference units to the conference system during operation. When adding conference units to the conference system, observe the maximum number of conference units in order to ensure operational reliability (see page 15). All delegate units are ready for immediate use. The chairperson units have to be reinitialized. Note that this will interrupt the conference (see page 54 or page 124). Recording a conference The ADN CU1 central unit allows you to record the floor channel and the channels of all active conference units as audio files on a USB mass storage device. Recording possibilities and requirements Recorded files The audio files are recorded in WAVE PCM sound file format (mono, 32 kHz/16 bit). The floor channel is recorded throughout the entire conference so that the course of the conference can be retraced. In addition to the floor channel, the channels of all active conference units are recorded as individual audio files. The audio data is not encrypted. For recording 1 hour of conferencing, you require approx. 230 MB of memory space per channel. If all channels of the conference system are being used (floor channel and 10 conference unit channels), you require approx. 2.5 GB of memory space. The USB mass storage device must meet the following requirements: USB mass storage device Requirements Recommended memory size > 500 GB File system* NTFS FAT32 Partition 1 Connection USB type A plug Interface USB 2.0 Power supply via USB socket (approx. 500 mA) or separate mains unit * When the maximum file size is reached (FAT32 = 4 GB), the recording is automatically split in several files. With NTFS files, the file size is limited by the memory size of the data storage device and the recordings don't have to be spit in several files. ADN Digital Conference System | 77

Running a conference
Muting the conference units’ loudspeakers for contributions coming from the
conference units’ microphones
The “
Mic Loudspeaker Mute
” function allows you to mute the conference units’
loudspeakers so that contributions coming from the conference units’ microphones
are not reproduced (see page 58 or page 131).
Adding conference units to the conference system

You can add conference units to the conference system during operation.
All delegate units are ready for immediate use. The chairperson units have to be re-
initialized. Note that this will interrupt the conference (see page 54 or page 124).

The ADN CU1 central unit allows you to record the floor channel and the channels
of all active conference units as audio files on a USB mass storage device.
