1 INTRODUCTION
•
genius
is a multifunction switcher with several applications: its different configurations
depend form the way the jumpers inside the equipment are set.
genius
can be used in
the following ways:
- manual or remote switcher
- audio detector with automatic switching
- balancing equipment with level setting
- audio distributor
- bi-channel splitting system or double MPX
- audio emergency system
- autofader system
•
genius
immediateness makes its use simple allowing remote control too.
•
genius
solves all the problems which can occur in all audio signal applications, deleting
every risky connection and assuring a safe and easy switching.
• Its features and conception have been studied to support its different applications at the
best:
- balanced inputs and outputs with very high S/N ratio to assure disturb immunity even in
difficult conditions while using long wires.
- EXPANDER BUS connector studied for cascade connection of several genius.
- Remote interface with optoisolated input and output controls and a section of relé
contacts.
For all these simple but useful peculiar features
genius
can be considered a genial
equipment.
2 OPERATIVE PRINCIPLES
genius
is a multifunction switcher with several applications: its different configurations depend
form the way the jumpers inside the equipment are set.
genius
features two electronically balanced inputs on XLR with DRAW plugs to withdraw
output service signals.
The A input can use the XLR signal (INDEPENDENT USE) or the EXPANDER BUS
(MASTER or SLAVE) signal, as shown in the block diagram.
The default setting is INDIPENDENT USE to allow the equipment to work independently, if
there is not a specific customer’s request.
The A input features a ±10 dB amplifying section set through the potentiometer on the front
panel.
The B input structure is different: it features a 50 μsec pre-emphasis and a 19 kHz sinusoid
oscillator, both set trough jumper.
