Applications and Accessories
Together with two matching transmitters from JTS,
the dual multifrequency receiver US-903DCPRO / 5
makes up a wireless audio transmission system
The wireless transmission of music or speech to
the audio system ensures the musician's freedom
of movement during the performance The trans-
mission range depends on the local conditions and
can reach to a maximum of 100 m
The receiver operates with "diversity" tech-
nology: The transmission signal is received by two
antennas placed at a distance from each other The
electronic system selects the signal of higher quality
and passes it on to the inputs of the receiving units
For reception, four transmission groups (A – D)
with 16 transmission channels each are available,
i e altogether 64 factory-set transmission channels
These channels in the UHF range of 518 – 542 MHz
can be selected as desired
The unit is supplied with four rechargeable
nickel metal hydride batteries (1300 mAh) which
can be used for power supply of two transmitters
and which can be conveniently charged via the
integrated charging unit
The following transmitters from the product
range of JTS can be used together with the receiver
US-903DCPRO / 5:
MH-8800G / 5 order no 25 5450
dynamic hand-held microphone with integrated
multifrequency transmitter
PT-920BG / 5 order no 25 5490
multifrequency pocket transmitter with Lavalier
microphone
To increase the range and the interference resist-
ance, two antenna amplifiers UB-900I (order
no 15 0830) available as accessories can be used
instead of the antennas supplied The amplifiers
are supplied with power via the antenna jacks of
the receiver
When using several receivers in the audio
system, the antenna splitter UA-960 (order no
15 0820) can be used It will also supply power for
a maximum of four receivers
