The HHa from Lectrosonics is a Digital Hybrid Wireless handheld transmitter sold without a microphone capsule. When paired with a receiver and mic capsule, it offers reliable, professional-quality wireless audio for a wide variety of applications including live performances, broadcast TV work, and productions for corporate events and houses of worship.

The HHa transmitter is engineered with a wide frequency response and wide dynamic range to deliver high-quality speech and vocal reinforcement. A compatible thread-on microphone capsule is required, and a wide variety of options from manufacturers including EV, Shure, Heil Sound, Telefunken, and many more are available separately. The gain is adjustable over a 45 dB range, while the built-in limiter helps you avoid clipping the input. In addition to its native 400-Series mode, the unit is also compatible with Lectrosonics 200 series, 100 series, and IFB receivers as well as other systems from top manufacturers.
