INSTALLATION
Advanced functions
•
Commutators (19 of fig. 1a) enable loudspeakers to be silenced and could activate 4 different
zones separately.
•
LINK IN input (34 of Fig. 1) is used to increase the disponibility of number of the microphones
connecting an expansion by one cable (Patch cord CAT 5 FTP 8 pin whit RJ45)
•
LINK OUT (37 of Fig.1c) is used to increase the disponibility of number of the microphones
connecting the expansion by one cable (Patch cord CAT 5 FTP 8 pin whit RJ45)
•
On the back panel, each microphonic input is arranged for insertion of 48V phantom power
supply and of high-pass filter through dip-switch (25 of fig. 1).
•
There are JUMPER on the Master module for internal setting of PRE OUT output pre/post
Master and pre/post the equalizer (JP16, JP17, JP18 of FIG.5).
•
Micro/line selection whit internal setting by jumper on the input module, jumper on=micro,
jumper open=line (JP7 of FIG.5)
•
INTERNAL MODIFIES
Any modify has to be made in an authorized assistance centre or in factory directly.
•
On each microphonic channel is possible to active the mute function of priority on the
remaining microphones. Each MUTE selected channel has the priority on the other
microphonic channels, which are going to be closed even if a speaker is talking. Also is
possible to set a channel in order than it can't be silenced by the MUTE function of the
other priority micro.
•
TAPE REC output supplies the direct signal of the inputs without the eventually settled
tone corrections, or the post master signal, that is whit all the corrections settled by the
tone and level controls.
•
OPTIONAL CARDS
Their insertion has to be made in an authorized assistance centre or directly in factory
•
On each channel and on master there is arrangement for volume remote control card
insertion (Internal setting FIG.5), that connection has to be made by shielded cable
connect to the connector (32 of fig.1), without section limitations for distances up to 150
mt.
In remote place is possible to use potentiometer volume control or a switch for the
ON/OFF function. For connector connections see Fig.2
•
The logic functions card has 4 selectable programs by the dip-switch (33 Fig.1).
a. FILIBUSTER: gets on this function when any microphone get activated prevent the
other microphones from get active till the speaker do a pause so long than the
relative microphone get deactivated. So the speaker than speaks can not be
interrupted.
b. ALL OVERRIDE: gets on this function all inputs are get actived, therefore the
microphonic signals are amplified as a not automatic mixer
c. NOM: set ON or OFF the NOM circuit that reducing the gain according to number of
open micophone.
d. LAST ON: blocking of the last microphone that maintain it active till it is not replaced
by the activation of another microphone. This function guaranties then environmental
acoustics is always present. Without this function, a long waiting in the conversation
causes the deactivation of all microphones; with the result of loses audio signal
effect.
