8 APPLICATIONS
genius
is a very flexible equipment and has many different application possibilities, according
to its different settings.
8.1 BI-CHANNEL SWITCHER
Its use as bi-channel or double mono switcher equipment does not require any internal
setting.
8.2 EMERGENCY SWITCHER
Its use as emergency switcher requires the enabling of the following functions and
connections:
1. Connect the source to be monitored to the A input.
2. Connect the emergency source to the B channel.
3. Enable the monitoring by the audio detector of the A input by inserting the J1 and J2
jumpers which send to the audio detector adder the Left A and Right A signals.
4. To modify the blinking time and frequency please take a look at the Audio Detector
section.
5. Insert the J21 and J22 to enable the commutation from the A to the B input; if you do not,
they will simply switch the audio detector relé and the multiplay photocoupler placed on
the remote door.
We suggest you to use the audio detector relé and the multiplay photocoupler to start the
equipment connected to the B input used as emergency source, or to connect it to
telecontrols to signal the presence of a problem.
The audio will be again commuted on the A input only when on the same A input it will be
present a signal for a longer time than the time set trough P12.
8.3 MPX SWITCHER
Its use as emergency switcher requires the enabling of the following functions and
connections:
1) Connect the network source to the A input
2) Connect the local source to the B input.
Both channels of the B input feature a 50 μsec pre-emphasis section and a 19 KHz settable
(sinusoid) section: to enable them you need to insert J9-J10-J11-J12 jumpers.
The BNC input for RDS allows its distribution on the two outputs, the internal trimmers P1 and
P2 allows setting of the different level on the two outputs.
By connecting more

equipment it is possible to distribute the network and RDS signals
trough the expander BUS to different equipment.
