Shure UR24S/BETA87C Handheld Wireless Microphone System
The Shure UR24S/BETA87C Handheld Wireless System features the UR4S Single Channel Diversity Receiver and the UR2/BETA87C Handheld Transmitter which consists of the UR2 Wireless Handheld Transmitter fitted with the Beta 87C Supercardioid Microphone capsule. The UHF-R is a professional, wireless technology engineered for the most demanding touring environments and installations. UHF-R wireless microphones 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 mic 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
