Handheld Wireless Microphone System

Professional grade.

The Shure UR24S/BETA58 Handheld Wireless System features the UR4S Single Channel Diversity Receiver and the UR2/Beta58 Handheld Transmitter which consists of the UR2 Wireless Handheld Transmitter fitted with the Beta 58A Supercardioid 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 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 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.

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 58A Vocal Microphone

The Shure Beta 58A is a high-output supercardioid dynamic vocal microphone designed for professional sound reinforcement and project studio recording. It has become a leading choice among vocalists and touring professionals worldwide. The Beta 58A maintains a true supercardioid pattern throughout its frequency range. This insures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. The Beta 58A has a shaped frequency response that is ideal for close up vocals. The superb performance of this microphone is not affected by rough handling because of its rugged construction, proven shock mount system, and hardened steel mesh grille.
