Shure BLX2 B58
The BLX2/B58 is the handheld transmitter half of the Shure BLX wireless system, topped with the BETA 58A supercardioid dynamic capsule that anchors countless live vocal rigs. The supercardioid pattern tightens rejection at the sides and rear for high gain before feedback, and the dynamic capsule handles loud stage levels while keeping handling noise low. It pairs with any BLX4 or BLX88 receiver to complete a system, and a -10 dB gain adjustment lets you match it to a strong vocalist without overloading the input.
Controls stay simple, with a single housing that runs up to 14 hours on two AA batteries and holds its link over a range up to 300 feet line of sight. This is the transmitter to buy as a spare, a second channel, or a capsule upgrade for an existing BLX vocal setup.
