Trusted Reliability. Expanded Efficiency. Ready For More.

Large conference and convention installations come with unique wireless challenges. ULX-D® Digital Wireless is the trusted and reliable partner for secure, scalable, and durable performance, campus-wide. With expanded wide-tuning frequency bands and up to a 40% increase in rechargeable battery run-time, ULX-D Wireless provides intelligent solutions for installations and event requirements of all sizes.

For higher channel counts in high-tier applications, the ANX4 Scalable Wireless Receiver receives up to 24 channels of Shure ULX-D wireless audio in a single rack space. Choose ANX4 to maximise use of your budget, rack space, and rack weight.

Uncompromising Digital Wireless Audio

• 24-bit/48 kHz digital audio that delivers incredibly clear and accurate reproduction of the source material
• 20 Hz – 20 kHz frequency range with flat response
• Greater than 120 dB dynamic range through the analog outputs
• 130 dB dynamic range (typical) using Dante and AES67 digital networked audio
• 60 dB of adjustable system gain easily accessible from the receiver front panel
• No transmitter gain adjustments needed: optimised for any input source
• Wide selection of trusted Shure Microphones

Extremely Efficient and Reliable RF Performance

• Expanded tuning range - ULXD1, ULX2, ULXD4D and ULXD4Q components now available with up to 166 MHz overall tuning range (region dependent)*
• Up to 17 active transmitters in one 6 MHz TV channel (23 on an 8 MHz TV channel)
• High Density mode enables up to 47 active transmitters in one 6 MHz TV channel (63 in one 8 MHz TV channel), with no audio quality degradation
• Rock-solid signal stability with no audio artifacts over the entire 100 meter line-of-sight range using standard supplied ½ wave antennas
• Selectable 1, 10, and 20 mW transmitter RF output power (comparable to 5 times the analog RF output power equivalent)
• For ease of use, optimised scanning automatically finds, prioritises, and selects the cleanest frequencies available.

*Note that ULXD4, ULXD6 and ULXD8 remain available for operation on legacy frequency bands
