Digital Hand Held Transmitter
General Technical Description
Introduction
The DHu handheld transmitter delivers superb audio
quality and extended operating range in a pure digital
architecture. Interchangeable microphone capsules
expand the versatility to suit a wide variety of applications and personal preferences. The superb audio performance and highly reliable RF transmission makes it
ideally suited for high end stage and studio production.
Frequency Selection
The transmitter tunes continuously from 470.100 to
607.975 MHz in 25 kHz steps, making it easy to find
clear operating frequencies. Operating frequency is
normally selected using a receiver or analyzer to assess signals in the local environment to avoid interference. Once an interference-free frequency is identified,
the transmitter frequency is set to match the receiver.
Input Gain Range and Limiter
45 dB range of input gain adjustment allows gain
settings to accurately match the user’s voice and the
varying sensitivity of different microphone capsules. A
DSP-controlled analog audio limiter is employed before the A-D converter. The limiter has a range of more
than 30 dB for excellent overload protection. A dual release envelope makes the limiter acoustically transparent while maintaining low distortion. It can be thought
of as two limiters in series, a fast attack and release
limiter followed by a slow attack and release limiter.
The limiter recovers quickly from brief transients, with
no audible side effects, and also recovers slowly from
sustained high levels to keep audio distortion low while
preserving short term dynamics.
Menu-Driven Control
A high-resolution LCD and control panel with membrane switches provide access to the menu-driven
setup. Transmitter RF power, low frequency rolloff,
frequency selection, backlight timeout settings and
programmable switch functions are easily accessed.
Antenna
A newly designed helical antenna allows the transmitter to be held in any position, since the user’s hands
have little or no effect on the RF output power.
Microphone Capsules
The transmitter is available from Lectrosonics with the
HHC cardioid condenser capsule. Capsules from several other manufacturers with a 1.25” x 28 thread pitch
and three contact rings are also available for use with
the transmitter. Condenser or dynamic microphone
heads can be used with the transmitter, depending on
the user’s preference or the application.
Side Button Functions
A programmable switch on the side of the housing can
be configured as a mute/cough switch, a power switch,
or be disabled.
USB Port for Firmware Updates
Firmware updates are enabled by simply downloading
a file and utility program from the Lectrosonics web
site, connecting the transmitter to a computer via the
USB port and running the program.
Long Battery Life
Switching power supplies throughout the design allow over 5 hours of operation using two alkaline AA
batteries. The battery compartment and contacts are
designed to prevent “rattle” as the unit is handled.
Rio Rancho, NM

per inch and three contact rings
Microphone Capsules:
Lectrosonics offers two types of capsules. The HHC is
the standard capsule and the HHVMC is the Variable
Mic Capsule which includes adjustments for Bass,
Midrange and Treble.
Do not touch the contacts between the mic capsule
and transmitter body. When necessary, the contacts
can be cleaned with a cotton swab and alcohol.

Along with these two models from Lectrosonics, a
variety of different capsules with the same thread
and electrical interface are available from the major
microphone manufacturers.
Capsules are attached with a right-hand thread.
To remove the windscreen from the mic capsule,
line up the blue wrench (included with the capsule
head) with the flat notches on the lower threaded area
of the mic capsule.
Align flats on the wrench with flats on the capsule.
A list of compatible capsules is on the website at www.

Gain
Phase
This setting is very important since it will affect the dynamic range that the wireless system will deliver. Gain
must be set according to the individual voice, the mic
capsule in use and the handling technique of the user.
LEDs and a bar type indicator in the LCD facilitate accurate gain adjustment.
IMPORTANT: See Input Gain Adjustment on the
next page for details.
The phase (polarity) of the audio can be inverted to
match other microphone capsules as needed. This is
normally used when “comb filtering” is heard. Comb filtering is an odd sounding distortion heard when two or
more microphones are mixed with different polarities.
Switch the transmitter setting back and forth between
Normal and Invert and listen to the audio to determine
which one is the better setting.
BatType
Freq.
The operating frequency is normally determined using
the scanning function in the receiver or with coordination software. The frequency is shown on the transmitter LCD display in MHz, and is set to match the
receiver. Press the MENU/SEL button repeatedly to
toggle back and forth between MHz and kHz. Adjustment is made in 25 kHz increments.
ProgSw
The Programmable Switch on the side of the housing
can be set to provide several functions, or it can be
bypassed.
This sets the battery monitoring for Alkaline or Lithium
batteries.
BatTime
Accumulated operating time (runtime) can be tracked
in the transmitter. The total runtime appears on the
BatTime setup screen, displayed in (hrs):(min). The
runtime is kept during battery changes, and must be
reset manually in the BatTime setup screen.
TxPower
Output power can be set to 25mW or 50mW as
needed for the application.

3) Hold the microphone the way it will be used in
actual operation.
The audio level is shown by LEDs
and a bar type indicator on the LCD.
4) Speak or sing at the same voice level that will
actually be used during the program, while observing the modulation LEDs. Use the UP/DOWN
buttons to adjust the gain until the –20 dB LED
starts to flicker red and the –10 dB glows green.
The gain should be set so that
the -20 LED just turns red on the
loudest peak (the onset of limiting).
The LEDs are marked for viewing when the mic capsule is held up to your mouth. They will glow either red
or green to indicate modulation levels as shown in the
following table.

Rio Rancho, NM
It is best to go through the following procedure with the
transmitter in the “standby” mode so that no audio will
enter the sound system, which could cause feedback.
5) Once the audio gain has been set, the RF output
can be turned on and the audio sent through the
sound system for overall level adjustments, monitor settings, etc.
NOTE: Full modulation is achieved when the
-20 LED first turns red. 30 dB of clean limiting is
available above this point.

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting cables and then go through the Troubleshooting section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop
attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection, send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units.
Once set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment. There are no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In-warranty repairs
are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it
does to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by
phone for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by letter or by phone. We need to
know the nature of the problem, the model number and the serial number of the equipment. We also need a
phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help
speed your repair through our receiving and repair departments. The return authorization number must be
clearly shown on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the
proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed”
for safe transport.
