Engineered for the most demanding touring applications.
The Shure UR124S/SM58 Dual Handheld Wireless Microphone System features the UR4D Dual Channel Diversity Receiver and two UR2/SM58 Handheld Transmitters which consists of the UHF-R Wireless Handheld Transmitter fitted with SM58 Cardioid Microphone capsule. The UHF-R is a professional, wireless technology engineered for the most demanding touring environments and installations. UHF-R wireless systems offer unprecedented flexibility and versatility. Using multiple frequency bands, over 108 compatible systems can be used simultaneously. Individual frequency bands deliver up to 60 compatible systems per band. The UHF-R also includes infrared synchronization that allows you to configure transmitter settings from the receiver.
Frequency Band Selection
Shure offers wireless systems in a selection of bands that conform to the different government regulations of specific nations or geographic regions. These regulations help limit radio frequency (RF) interference among different wireless devices and prevent interference with local public communications channels, such as television and emergency broadcasts. The system's band and frequency range are identified on the face of the receiver and transmitter.
Groups and Channels
To transmit audio through a wireless system, the transmitter and receiver must be set to the same radio frequency, or channel. A wide selection of channels allows more microphones to be used at the same time, since each microphone must operate on a different channel. It also provides a greater choice of open channels--those that are free from interference from television broadcasts, electronic devices, or other wireless systems. A group is a selection of compatible channels. Wireless microphones work better together when set to channels in the same group.
Automatic Frequency Selection
The following features scan the RF environment to find the best group and channel settings for a particular installation.
¢Group Scan--finds the group with the most open channels, then sets all networked receivers to channels in that group
¢Channel Scan--finds the first open channel in the currently selected group and sets the receiver to that channel
Automatic Transmitter Sync
This feature automatically transfers the group and channel settings from a receiver to a transmitter. You can also program other transmitter settings on a receiver and transfer those settings too.
This feature locks the receiver and transmitters so that users cannot change settings. The transmitter power switch can also be disabled so that the transmitter remains on if the power switch is accidentally toggled during a performance.
Audio Gain Structure
The following settings allow you to adjust audio gain throughout the system:
¢ Sensitivity (bodypack only). A 25 dB range of gain adjustment at the bodypack transmitter input
¢Transmitter Gain. A 30dB range of audio gain adjustment within the transmitter (affects audio level at the receiver, as indicated by
the Audio LEDS.)
¢Output Level. 32 dB of attenuation at the receiver output, plus a mute setting
¢-30 dB pad for matching audio levels at the receiver XLR output
Each receiver has an RJ-45 port on the back for connecting to other receivers over an Ethernet network. Networking receivers allows you to automatically set channels for all the receivers with a single group scan command. You can also control and monitor all networked receivers through the Shure Wireless Workbench PC software.
Shure Wireless Workbench Software
The Shure Wireless Workbench software on the supplied CD includes a variety of useful tools for installing and managing multiple wireless systems. Simply install the software on your computer and connect it to a network of receivers to monitor and control receivers and transmitters throughout the network.
UR4D Dual Channel Diversity Receiver
The UR4D Dual Channel Diversity Receiver has the latest in wireless technologies including Shure's patented Audio Reference Companding for crystal-clear sound beyond the limits of conventional wireless technology. The UR4D dual channel receiver provides advanced control and robust flexibility for a wide range of professional uses.
UR2 Handheld Transmitter
UHF-R handheld transmitters boast a rugged, lightweight construction and an antenna design which advances RF transmission reliability. The transmitter design allows for interchangeable microphone cartridges.
SM58 Vocal Microphone
The SM58 unidirectional dynamic vocal microphone is designed for professional vocal use in live performance, sound reinforcement, and studio recording. It has a tailored vocal response tuned to accentuate the warmth and clarity of lead and back-up vocals. A highly effective, built-in spherical filter minimizes wind and breath "pop" noise. The cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. Rugged construction, a proven shock-mount system, and a steel mesh grille ensure that even with rough handling the SM58 will perform consistently outdoors or indoors. The SM58 has consistently been the first choice of performers everywhere.
Consumer Alert:Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCCs wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones.
