Optimized for Vocals and Speech

They feature a neodymium magnet for high sensitivity and output, a tight supercardioid polar pattern to minimize background noise, and a dent-resistant steel mesh grille. The built-in pop filter reduces wind and breath noise for clear speech.

The durable BLX2 handheld transmitters are lightweight and comfortable to hold. They have group- and channel-selection buttons for easy frequency matching with the receiver, plus an on/off button, adjustable gain control, and a black identification cap. The WA621 Color ID Caps kit is available as an accessory.

It has two LED displays for group and channel settings, and four LED lights to show system readiness and incoming audio signal strength. It offers two 1/4' and two XLR outputs for connecting to PA systems and mixing boards.
