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

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:

This button is used to select menu items and enter setup screens during

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.

PWR/BACK Button
Press the PWR/BACK switch to turn the power on. Press and hold it until the
display goes blank to turn power off. It also functions as a “back” button while
navigating the various menus and setup screens to return to the previous
screen or menu item.
The firmware “remembers” whether the receiver was turned on or off after
power is disconnected, and it returns to that state when power is restored.
This allows the receiver to power up and down as the camera or external supply is turned on and off.
Press the PWR/BACK button from the Main Window to briefly display the
external power voltage.
UP/DOWN Arrow Buttons
The UP and DOWN arrow buttons are used to select various options and
adjust values in the setup screens, and provide secondary functions such as
locking out the panel to guard against accidental changes.
Installing Rear Panel Adapters
Installation of the rear panel output/power adapters is the same for all models.
Panels are held in
place by two Phillips
head screws on the
sides of the housing.
Connections
between the panel
and main circuit
board are made via
miniature mating
connectors.
Align the mating
connectors and slide
the panel straight
into the housing until
the screw holes align
with the housing.

Battery Adapters
Battery sled adapters configure the receiver for standalone use or to provide
battery backup power. Several options are available:
• SRBATTSLEDTOP
• SRBATTSLEDBOTTOM
• SR9VBP (inserts into the SLED adapters)
SRBATTSLEDTOP
SRBATTSLEDBOTTOM
The battery sled adapters accept L and M type video camera rechargeable

whichever delivers the highest voltage.

First, turn off all of the transmitters you intend to use with the receiver.
Navigate to the SETUP/SCAN screen and press the MENU/SEL button to
start the scanner. The display will switch to the Scan Window (see illustration
above) and start scanning immediately. Allow the receiver to scan across the
entire tuning range at least once, then press the MENU/SEL button to stop
the scanning.
Scroll through the screen with the UP and DOWN buttons and find a frequency where no (or very weak) RF signals are present. Press the PWR/BACK
button to set the receiver to this new frequency.
Press both the UP and DOWN buttons at the same time to switch to the
Zoom View Window (see illustration above). In this view, the cursor remains
fixed in the center of the screen and the background scrolls behind it. The
frequency can be stepped up and down in 100 kHz increments using the UP
and DOWN arrow buttons.
When the receiver is configured for SWITCHED diversity (dual channel
mode), two cursors will appear when the scanning is stopped. Press MENU/
SEL to toggle between the two receivers. The cursor for the selected receiver
will be a dashed rather than solid line. Select each receiver and use the UP
and DOWN buttons to locate a frequency with no (or very weak) RF activity.
Keep the frequencies of the two receivers at least 700 kHz apart to minimize
de-sensing (short range) issues. This spacing is a “worst case” approximation
assuming the transmitters are about 25 feet from the receiver antennas.
Data gathered during a scan is stored until it is intentionally erased or the
power is turned off. Previous data will remain and subsequent scans can be
made to search for additional signals or to accumulate higher peaks.
To clear the scan memory and screens, press the back button several times to
return to the Main Window, then press and hold the PWR/BACK button briefly.
As soon as Powering off... appears on the display, release the button. The
receiver will remain turned on, and the scan data will be erased.
Set your transmitter to the same frequency as shown on the receiver display,
turn the transmitter on and verify that a strong RF signal is present.
