NE 900
UHF Diversity Receiver
APPLICATIONS
The NE 900 UHF diversity receiver with PLL synthesizer technology
has been developed for professional use at broadcasting studios,
film, on stage etc. The receiver is available in three versions:
one-channel (NE 900 S), two-channel (NE 900 D ) or four-channel
(NE 900 Q). The NE 900 operates in the frequency bands 668 to
692 MHz, 774 to 798 MHz, 790 to 814 MHz and 841 to 865 MHz.
Each TV channel provides 100 pre-programmed frequencies.
A maximum of 16 frequencies can be operated simultaneously
without any interference.
By using the SCAN function an automatic channel search is started
and with the ACT function (Automatic Channel Targeting) the
discovered frequency is transmitted to the transmitter via infra red.
The frequency can also be selected manually.
The menu control is used to access and set the individual parameters.
The colour display shows all parameters such as RF and AF level,
diversity channel, battery status of the transmitter as well as all
menu settings such as frequency, group, channel, squelch, output
level, user name and address.
A sophisticated adjustable squelch system prevents unwanted noise
effectively. The pilot tone-controlled AF mute suppresses inter-
ferences and mutes the receiver when the appropriate transmitter
is switched off.
