The Shure UR24S/BETA87A Wireless System features the UR4S Single Channel Diversity Receiver and the UR2/BETA87A Handheld Transmitter which consists of the UR2 Wireless Handheld Transmitter fitted with the Beta 87A Supercardioid Microphone capsule. The UHF-R is a professional, wireless technology engineered for the most demanding touring environments and installations. UHF-R wireless microphone 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 includes infrared synchronization that allows you to configure transmitter settings from the receiver, as well as these outstanding features:

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 microphone 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 Shure 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.

Interface Lock

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


Networking

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.

UR4S Single Channel Diversity Receiver

The UR4S Single 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 UR4S receiver provides advanced control and robust flexibility for a wide range of professional uses.

UR2 Handheld Transmitter

The UR2 handheld transmitter has a rugged, lightweight construction and an antenna design which advances RF (radio frequency) transmission reliability. The transmitter design allows for interchangeable microphone cartridges.

Beta 87A Vocal Microphone

The Shure Beta 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level capability. Used for professional sound reinforcement, broadcasting, and studio recording applications, the Beta 87A combines superb performance with the ruggedness needed for touring and field production.

The Beta 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the "boomy" sound often associated with close pick-up. The characteristic Shure presence rise brightens the upper midrange. The tight supercardioid pattern, with null points at approximately 125 degrees, provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The Beta 87A operates on phantom power.
