Shure ULXD2/B87C Digital Handheld Wireless Microphone Transmitter with Beta 87C Capsule

The Shure ULXD2/B87C=-G50 is a handheld wireless microphone transmitter created for engineers, performers, and presenters who need dependable sound and secure transmission. It works within the Shure ULX-D ecosystem and brings together 24-bit, 48 kHz digital audio with the renowned Beta 87C capsule, so voices come through with a clarity that cuts through busy mixes while retaining a natural tonal balance.

The Beta 87C capsule has a cardioid pickup pattern that focuses on the voice and reduces room noise, which is helpful on loud stages, in houses of worship, or during corporate keynotes where spill and feedback can be a problem. A smooth high-frequency response adds detail without harshness, letting vocalists and speakers sound polished without relying on heavy equalization.

For teams that manage multiple wireless channels, the transmitter’s 330-foot operating range and robust RF performance simplify placement of receivers and antennas. AES 256-bit encryption keeps the signal private, a key requirement for boardrooms, government facilities, and broadcast environments where confidentiality matters.

On the practical side, the housing is made from lightweight aluminum, so it stands up to touring while remaining comfortable to hold during long sets or day-long conferences. A bright backlit LCD shows frequency, battery status, and menu options, which means quick checks and changes even when stage lights are low.

Power can come from standard AA batteries or the optional Shure SB900B rechargeable pack. With the SB900B, runtime stretches past twelve hours and the external contacts let crews drop the transmitter into a charging dock between shows without removing the battery.

Whether you are outfitting a rental inventory, upgrading a church’s microphone package, or giving a keynote in a large convention hall, the ULXD2/B87C=-G50 offers the sound quality, security, and day-to-day practicality that modern productions expect.
