Digital Hybrid Wireless
The Lectrosonics Digital Hybrid Wireless® uses innovative technology to
combine the advantages of digital audio with the advantages of analog RF
transmission. The result delivers the superior sound quality of a digital system
and the excellent range of an analog system.
A proprietary algorithm encodes the digital audio information into an analog
format which can be transmitted in a robust manner over an analog FM wireless link. The receiver employs state-of-the-art filters, RF amplifiers, mixers
and detector to capture the encoded signal and a DSP recovers the original
digital audio.
This digital/analog hybrid technique has some very beneficial properties.
Because the information being transmitted is digitally encoded, immunity to
noise is much higher than what a compandor can offer. Because the encoded
audio is sent in analog format, spectral and power efficiency and operating
range are not compromised.
Under weak RF conditions, the received signal degrades gracefully, like an
analog system, delivering as much usable audio as possible at maximum
range. Since the audio is free of compandor artifacts, pumping and breathing
problems are also greatly reduced.

Quick Start Summary
The following checklist includes the minimum required settings to start using
the receiver.
• Install either a battery sled or camera slot adapter kit (see pages 5-6).
• Connect power to the receiver (see page 6-7).
• Set the DIVMODE for single or dual channel operation (see pages 8-9).
• Set the COMPAT (compatibility) mode for the transmitters to be used (see
pages 8-9).
• Find clear operating frequencies for one or both receivers (see page 10).
• Set transmitters on the matching frequencies (see transmitter manual).
• Verify transmitters are set to the same compatibility mode as the receiver
(see transmitter manual).
• Adjust transmitter input gain to match voice level and mic position (see
transmitter manual).
• Adjust receiver output level as needed for the camera or mixer input level
desired (see pages 8-9).
IMPORTANT:
Performance will be degraded if
FREQ.
WARNING
Receiver 2 is set 4.2 to 4.8 MHz higher
than Receiver 1. The LCD will also flash

In addition to the audio outputs on the rear panel, the front panel of the receiver provides a second set of outputs through a 5-pin connector. This allows
both audio channels to be connected through external cables for cameras
with only one audio channel enabled in the slot.
The TA5M connector provides two balanced outputs with the following pinouts:

LCD Screen
A backlit, graphics-type LCD is used to set up and monitor the receiver. The
Main Window shown above is used during normal operation, to display RF
and audio levels, transmitter battery status, pilot tone status and diversity
activity for both receivers.
MENU/SEL Button
This button is used to select menu items and enter setup screens during
setup.
IR (Infrared) Sync
An IR Sync Port is used for quick setup with transmitters that offer this feature.
Settings for frequency, step size, compatibility mode and talk back are transferred from receiver to transmitter via the IR ports.

NOTE: Selected compatibility mode and talk back will only sync if they
are available options on the transmitter you are syncing with.
