STU 2200
4 CHANNEL UHF DIGITAL TRANSMITTER UNIT FOR SIMULTANEOUS TRANSLATION

STU 2200 is the digital radio transmitting unit of the Forum 2000 system.

It has to be connected to the system main unit FMU 9100, able to directly manage the Forum 9000 microphone sets or to interface any analogue system like RCF Forum 6000 or even a simple mixer-preamplifier, through one CAT 5 UTP cable. STU 2200 sends “by UHF radio frequencies” the floor language and the translated languages with proper data encryption, in order to guarantee privacy and total safety.

It has a graphic display with related keys to simply select among the 99 available channels, in case two or more FORUM 2000 systems work together in close environments like a congress centre. High performance antennas are provided to easily and quickly cover an area of up to 6.000 to 10.000 sq. metres.
