HHa Data Sheet

Interchangeable Capsules (*Sold Separately)
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.*

Digital Hybrid Wireless®
Digital Hybrid Wireless® is a revolutionary design that combines digital audio with an analog FM radio link to provide both outstanding audio quality and exemplary, noise-free RF performance. Using a patented algorithm to encode 24-bit digital audio information in the transmitter into an analog format, the encoded signal is then transmitted over an analog FM wireless link. At the receiver, the signal is then decoded to restore the original digital audio. This process eliminates compandor artifacts and produces an audio frequency response flat to 20 kHz. (US Patent 7,225,135)

Selectable RF Transmission Power
The transmitter allows the user to select between two power settings depending on the needs of the situation. The lower RF power setting uses slightly less current, thus battery life is enhanced. The higher power setting provides greater range and resistance to dropouts. Selecting the RF power is accomplished using the control menu.

IR Sync
An IR port is provided on the control panel to transport settings from a receiver to the transmitter.
