The Shure BLX2/PG58 is a professional wireless handheld transmitter that integrates the proven PG58 dynamic vocal capsule into a reliable UHF wireless body. This transmitter is designed as a key component of the BLX wireless system, providing performers and presenters with a familiar and trusted vocal sound coupled with the freedom of wireless operation. The PG58 capsule is renowned for its tailored frequency response that emphasizes vocal presence and clarity, along with a built-in spherical wind and pop filter that effectively minimizes plosive sounds. Its cardioid polar pattern provides good rejection of off-axis noise and feedback, making it a dependable choice for live vocal applications in a wide range of environments, from live music to public speaking.

The BLX2 transmitter body is built for durability, featuring a sturdy construction with a steel grille to protect the capsule from impact. It houses the wireless electronics, including an intuitive interface with clear status LEDs that indicate power and link condition. The transmitter is designed for ease of use, automatically syncing with a compatible BLX receiver with a single button press after an optimal frequency is selected. It operates on two AA batteries, offering long battery life to power through extended performances or full-day events. The ergonomic design ensures a comfortable grip, making it suitable for extended use during concerts, ceremonies, or presentations.

As a standalone transmitter, the BLX2/PG58 is used to replace or add to existing BLX systems or is purchased as part of a complete system bundle. It embodies the core principle of the BLX series: delivering professional Shure microphone sound with wireless technology that is accessible, reliable, and simple to operate. This combination makes it an excellent choice for musicians, worship teams, educators, and AV rental companies seeking a cost-effective and robust wireless vocal solution with a well-established sonic pedigree.
