Multi-room mode
SpeechLine Digital Wireless, by taking into account the installation size as well as country-
specific regulations, allows to optimally use the 1.9 GHz frequency band.
SpeechLine Digital Wireless offers two operating modes for different types of installation: the
automatic mode with adaptive transmission power for single-room installations (Adaptive
Power Mode) and the manual mode for multi-room installations, which is known as Multi-
Room Mode.
For up to 20* links used in parallel, the Adaptive Power Mode ensures extremely easy startup
and a reliable maximum range.
The Multi-Room Mode allows you to adjust the transmission power to allow for a
considerably larger number of links.
These adjustment options make SpeechLine Digital Wireless the optimum solution for a great
variety of projects with widely differing installation sizes at the same location.
* depending on the locally approved variant (see Country-Specific Variants).
When installing and starting up SpeechLine Digital Wireless systems in projects of different
sizes, observe the following steps.
