OUT LEVEL
Trimmer to adjust the audio output level (a tool is needed).
Note: the common audio level of all connected paging microphones is set by
using the configuration software for PC. The BM 7601 trimmer can be used to
adjust the microphone level when compared to other units in the system.

BM 7601 paging microphones are for indoor use only and can be connected to
the either the “System Bus” or the “Local Bus” (through CAT5 or CAT6 cable) of
the DXT 7000EN system.
A dedicated network is highly recommended. Make sure not to use cables already
assigned for Ethernet / Intranet (note: the bus is not compatible with Ethernet).
There can be several parallel connected units in a single bus.
The total cable length cannot exceed 1200 metres.
A system bus can normally provide enough power for all paging microphones (no
need of external power supply units). Anyway, if many units with remarkably long
cables are used, the voltage drop will need to be measured and evaluated.
