Wideband Digital Hybrid
®
Plug-On Transmitter
Rio Rancho, NM
3
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
wide 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 all Digital Hybrid
receivers, and is backward compatible for use with Lec-
trosonics 200 and 100 Series, Mode 3, Mode 6, Mode
7, and IFB receivers and some other brands of analog
wireless receivers. Companion receivers are covered in
separate manuals. Your Lectrosonics representative can
guide you through any compatibility concerns.
