The ULXP4 offers an exceptional value in both performance and price, for both working musicians and sound installers.

ULX2 Handheld Transmitter

The ULX2 Handheld Transmitter has a 3-segment battery fuel guage, Backlit LCD shows group and channel, Frequency and power settings, and Control lockout.

Beta 87A Vocal Microphone

The Shure Beta 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level capability. Used for professional sound reinforcement, broadcasting, and studio recording applications, the Beta 87A combines superb performance with the ruggedness needed for touring and field production.

The Beta 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the "boomy" sound often associated with close pick-up. The characteristic Shure presence rise brightens the upper midrange. The tight supercardioid pattern, with null points at approximately 125 degrees, provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The Beta 87A operates on phantom power.
