Introduction

Thank you for selecting a Lectrosonics HMa plug-On 

transmitter. The unique design provides several distinct 

features for professional applications:

•  Outstanding RF operating range
•  Superb audio quality
•  Corrosion-resistant housing
•  Programmable compatibility modes for use with a  

variety of different receivers

The Digital Hybrid Wireless

®

 design (US Patent 

7,225,135) combines 24-bit digital audio with analog 

FM resulting in a system that has the same operating 

range as analog systems, the same spectral efficiency 

as analog systems, the same long battery life as analog 

systems, plus the excellent audio fidelity typical of pure 

digital systems.
The transmitter uses a standard 3-pin XLR input jack for 

use with any microphone with a a mating XLR connec-

tor. An LCD, membrane switches and multi-color LEDs 

on the control panel make input gain adjustments and 

frequency and compatibility mode selection quick and 

accurate, without having to view the receiver. The hous-

ing is machined from a solid aluminum block to provide 

a lightweight and rugged package. A special non-corro-

sive finish resists salt water exposure and perspiration 

in extreme environments.
The DSP-based design works with Digital Hybrid 

receivers, and is also compatible with Lectrosonics IFB 

receivers. Companion receivers are covered in separate 

manuals.
