ULXP4 Wireless Diversity Receiver
The expanded feature set of the ULXP4 wireless receiver, with advanced settings and controls including lockable settings and group scan, offers a direct path to full, clear audio signals. The ULXP4 offers an exceptional value in both performance and price, for both working musicians and sound installers.
ULX1 Wireless Bodypack Transmitter
The low-profile, highly durable body-pack ULX1 has all the characteristics to meet the demands of high performance. For use with headworn, lavalier and instrument microphones, as well as guitars and basses. Attaches to belt, waistband or guitar strap with clip for hands-free mobility.
ULX2 Handheld Transmitter
The ULX2 Handheld Transmitter features 3-segment battery fuel gauge, frequency and power settings, and control lockout. A backlit LCD shows group and channel.
Beta 87C Vocal Microphone
The Beta 87C premium vocal microphone delivers studio-grade performance and a smooth, extended high-end frequency response in a cardioid condenser design. The microphone adds warmth to the frequency response and creates an ideal environment for in ear personal monitoring. And its highly consistent cardioid pattern offers excellent rear rejection.
