ULX WIRELESS SYSTEM
Specification Sheet
Architects’ and Engineers’ Specifications
The wireless system shall operate in the UHF band between 554 MHz and 865 MHz, with the specific available frequency range being
dependent on the user’s locale. Effective range of the system, receiver to transmitter, shall be 100 meters (300 ft.), under optimal conditions.
The system shall allow selection of over 1400 operating frequencies across 36 MHz of bandwidth in order to avoid RF interference. Optimal
frequencies shall be selected automatically , ensuring that individual systems run at their highest level of performance, and that multiple systems in simultaneous use do not interfere with one another.
Each transmitter shall be powered by a single 9V battery . Transmitters shall have a power on/of f switch, as well as a backlit LCD showing group and channel, peak indication, and battery strength. Available transmitters shall include a body pack for use with electric guitars,
basses, and other electric instruments, as well as lavalier or headset microphones, and a handheld microphone for vocals. The body pack
shall include a –20dB pad switch to compensate for higher- or lower-gain devices.
The receiver shall have a multi-function display showing group, channel, frequency, squelch level, transmitter battery strength, and
locked/unlocked status. The system shall use diversity technology to improve reception, minimize signal dropouts, and achieve the best
possible signal–to–noise ratio. Tone key squelch, and noise squelch circuitry shall be built in to the system to provide optimal sound quality
and minimize unwanted noise. The receiver shall include an RF meter, an audio level meter, and a volume control.
The system shall be the Shure ULX Wireless.
