“REC” is set for eventual total log event external recording purposes. Such signal inputs are to be selected
respectively throughout the input commutator ref.2-fig1, level set by volume control ref.3-fig1 and sent to
the different eight zones throughout the relevant keys ref.5-fig1.
9.1.2 VOX/AUX-MESSAGE-TELEPHONE – VOX –Inputs with priority levels
3 high level audio inputs are available and are priority VOX

9.1.3 BASES INPUTS – Call station microphones inputs
On the unit rear panel N° 6 RJ45 inputs are available to be used for Zone8 BM08/BM04/BM01 microphone
stand connection throughout CAT5 cable, On each of these 6 inputs it is possible to connect in cascade
N°. 3 call station microphones for a total of N° 18 microphone stands.
NB – The microphone stands present and involved by the configuration are directly power supplied by
ZONE8 unit.
But for lengths over than 200/250 meters there could be some excessive power level decrease visualized
by Low Mains led Indicator. Led set rear BMO1-BM04-BM08 microphone call stations. In this case the
local call microphone station power supply purposes are necessary throughout the optional
( to be purchased separately ) power supply unit BMPWS ((230VAC/12V~ – 500mA ).
UTP CAT5 cable and RJ45 connector details for call microphone station connections in accordance with
EIA/TIA – 568B standards
