The DHu Digital Hybrid Wireless handheld transmitter represents a versatile solution for a variety of wireless microphone applications including live performance, broadcast, AV rental and houses of worship. The design incorporates advanced features to provide high-quality speech and vocal reinforcement. Lectrosonics offers the HHC cardioid condenser capsule. Thread-on capsules from other manufacturers using a 1.25” opening and 28 thread pitch can also be used, including those from manufacturers such as EV, Shure, Heil Sound, Earthworks, Telefunken and others.

The transmitter benefits from a second generation design with specially developed, high efficiency digital circuitry for extended operating time on two AA batteries. The transmitter can tune across the UHF television band from 470.100 to 607.950 MHz, with a selectable output power of 25 or 50 mW. The pure digital architecture enables AES 256-CTR encryption for applications that require high level security. Studio quality audio performance is assured by high quality components, wide range audio gain adjustment in fine increments, and a DSP-controlled, dual envelope limiter. Low frequency audio roll-off is adjustable to tailor the sound as needed for a variety of applications. Setup is easy using membrane switches on a concealed control panel. An IR (infrared) port on the control panel allows settings to be transferred between receiver and transmitter. A programmable switch on the outside of the housing can be configured as a cough or mute switch, a power switch, or be bypassed.
