The DHu Digital Encrypted 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.

Interchangeable Capsules

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 SoundTM, Earthworks®, Telefunken® and others.*

The transmitter benefits from a 4th 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 to 608 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 for push-to-talk, cough, mute, talkback, power on/off, or be bypassed.
