Chris Lyons explains how High Density mode, available in the Shure ULX-D Digital Wireless System, allows up to 47 systems to operate in just 6 MHz of spectrum, with a working range of 100 feet. This feature is debuting at InfoComm 2012.
Chris Lyons previews two new additions to the Shure ULX-D Digital Wireless System: the ULXD4D Dual Channel Receiver and the ULXD4Q Quad Channel Receiver. Both are debuting at InfoComm 2012.
ULX-D Digital Wireless System for professional installed sound reinforcement
Shure ULX-D offers a premium 24-bit/48kHz digital audio quality combined with spectrum-efficient and intelligent RF performance, meeting the needs of demanding Installed Applications. ULX-D employs the Advanced Encryption Standard (AES-256) for high-security applications, allows for a seamless integration in current media control systems, and utilizes latest rechargeability technology, originating from Axient. ULXD4D (Dual) and ULXD4Q (Quad) receivers come with an extensive set of additional features including High Density Mode, Bodypack Frequency Diversity and DANTE digital audio networking.
- 24-bit / 48 kHz digital audio delivers incredibly clear and accurate capturing of the source material
- Wide frequency range with flat response for superb low range and transient response
- 120 dB dynamic range provides excellent signal-to-noise performance
- ~120dB dynamic range with XLR, ~130dB with Dante
- Wide selection of trusted Shure Microphones
- 64-72 MHz wide frequency band versions
- 8 MHz TV = 17 WL Channels at 10 mW, preprogrammed (22 WL Channels, optimally calculated)
- 1 mW, 10 mW, 20 mW menue-selectable RF power options
- Signal stability with no audio artifacts extends over the entire 100 meter line-of-sight range using standard supplied dipole antennas
- Optimized scanning automatically finds and deploys the cleanest frequencies available
- Advanced Encryption Standard (AES-256)
- A new, unique, randomized encryption key is generated every time encryption is enabled
- Enabled via front panel menu on the receiver and sent over IR sync
Operation and Configuration
- Proprietary Shure Gain Ranging optimizes the system’s dynamic range for any input source and eliminates the need for gain adjustments at the transmitter
- Up to 60 dB of adjustable system gain is easily accessible from the receiver front panel
- Interference detection and alerts provide instant confirmation when interference is present
- Ethernet networking for streamlined setup across multiple receivers, Wireless Workbench 6 (WWB6) integration, as well as AMX and Crestron control
Support for frequency coordination with the Axient™ Spectrum Manager
Rugged metal housing on both transmitters and receiver
- LCD screens with adjustable contrast and brightness on both transmitters and receivers
- Adapted from Axient™ intelligent power management technology
- Lithium-Ion chemistry and intelligent Shure battery circuitry results in rechargeable batteries with zero memory effect. The battery can be recharged at any time; a complete discharge is not necessary
- Provides ULX-D handheld and bodypack transmitters with 12+ hours of performance time
- Transmitters and receivers display remaining battery life in hours and minutes accurate to within 15 minutes
- SBC200 Dual Docking Charger recharges batteries while inside or outside transmitters
- Up to four SBC200s can be linked together to provide docked charging of eight transmitters from one power supply
- The SBC800 Eight-Bay Charger brings up to eight SB900 batteries to full charge within three hours and 50 % charge in one hour, with charge status LEDs for each battery
- AA-sized battery backwards compatibility
- Both chargers fit in a standard-size rack drawer for easy transport and storage
High Density mode
- Specifically designed for high channel count applications requiring a working range up to 30 meters, the High Density Mode allows operating up to 560 (five hundred sixty) channels in 72 MHz, respectively 63 channels in an 8 MHz TV channel over standard mode at 1mW transmit power.
ULXD4D (Dual) and ULXD4Q (Quad)
- The 1RU metal chassis with internal power supply houses two, respectively four independent receivers, each with their own audio and RF meters, gain control and XLR outputs.
- Plus with RF cascade and two Ethernet ports, units can easily share the RF signal and be networked together for simplified multi-channel frequency coordination and deployment.
Bodypack Frequency Diversity (Dual and Quad only)
- Bodypack Frequency Diversity safeguards against loss of audio signal caused by RF interference or by power loss in a transmitter.
- The signals from a common source via two bodypack transmitters with different frequencies are routed to receiver’s audio outputs.
- Switching between channels occurs in milliseconds, without interruption the audio signal.
- Bodypack Frequency Diversity and Audio Summing are complimentary features and can be simultaneously active
Audio Summing (Dual and Quad only)
- Combining of selected audio channels to be routed to all selected outputs and allows the receiver to function as a 2 or 4 channel mixer. All XLR outputs of the selected channels provide the summed audio.
- Bodypack Frequency Diversity and Audio Summing are complimentary features and can be simultaneously active.
DANTE™ Digital Audio Networking Over Ethernet (Dual and Quad only)
- Digital audio is carried over standard Ethernet using shielded Cat5e (or higher)
- cables. Dante™ provides low latency, tight clock synchronization, and high Quality of-
- Service (QoS) to provide reliable audio transport to a variety of Dante devices.
