JTS US-903DC
    16 / 64 Channel UHF PLL Dual Transmitter Diversity Receiver


















    Overview:  
    The JTS US 903d Receiver is a diversity dual tuner, DUAL Channel, twin antenna receiver featuring 16
    selectable UHF channels with 4 Groups of 16 channel presets for both receivers: A & B .  The US 903
    essentially offers 2 receivers in one housing in a one rack space design.  The US 903d receiver offers the
    capability to use Two Mh 8880G Handheld transmitters, Two PT 920Gmi belt pack transmitters or One Mh
    8880 H.H. transmitter and One PT 920Gmi belt pack transmitter. The US 903d receiver and companion
    transmitters, the Mh 8800G Handheld transmitter and the PT 920Gmi  Belt Pack transmitter feature menu
    driven LCD displays providing for easy operation of the system. The JTS US 903DC receiver also features
    a built in convenient Ni cad Battery charger for recharging 4 pcs. of AA Ni cad batteries as used in the
    JTS Mh 8800G and  the PT 920Gmi transmitters. Typical battery life of the transmitters is 12 -14 hrs.
    before having to recharge the AA batteries used in the transmitters which use 2 pc. of AA batteries each..
    PLL (Phase Locked Loop) synthesized control circuitry is utilized to provide stable RF signals.  16
    frequencies per group, are selectable and can be programmed for both the US 903d receiver and the
    compatible Mh 8800G H.H. and PT 920Gmi belt pack transmitters. Up to 4 US 903 systems can be
    configured to operate simultaneously on the same stage or venue.

    Features·        
  • DUAL Transmitter operation.·
