The HHa handheld transmitter uses state-of-the-art
Digital Hybrid Wireless® wireless technology, selectable output power and a versatile microphone capsule
mounting system to meet the needs of audio professionals and vocalists.
The compandor-free Digital Hybrid audio chain preserves the quality of the selected microphone capsule
and delivers it to the sound and recording system
without coloration. This superb audio performance and
highly reliable RF transmission makes it ideally suited
for high end stage and studio production.
Digital Signal Processor
The DSP encodes the digitized audio from the A-D
converter and adds an ultrasonic pilot tone to control
the receiver’s squelch in systems that use pilot tone. It
also controls the input limiter and audio metering.
Compatibility Modes
The transmitter was designed to operate with Lectrosonics Digital Hybrid Wireless® receivers and will
yield the best performance when doing so. Along with
providing peerless audio quality with wide frequency
response and dynamic range in Nu Hybrid mode, the
technology used in the HHa includes compatibility
modes for Lectrosonics Mode 3 and IFB receivers.
Digital Hybrid Wireless® Technology
All wireless links suffer from channel noise to some
degree and all wireless microphone systems seek to
minimize the impact of that noise on the desired signal.
Conventional analog systems use compandors to
increase the signal to noise ratio, at the cost of distortion artifacts. Wholly digital systems defeat the noise
by sending the audio information in digital form, at
the cost of some combination of power, bandwidth or
channel count.
The Lectrosonics Digital Hybrid Wireless® system overcomes channel noise by digitally encoding the audio
in the transmitter and decoding it in the receiver, yet
still sending the encoded information via an analog FM
wireless link. This proprietary algorithm is not a digital
implementation of an analog compandor. Instead, it
is a technique that can be accomplished only in the
digital domain, even though the inputs and outputs are
analog signals.
Because it uses an analog FM link, the system enjoys
all the benefits of conventional FM wireless systems,
such as excellent range, efficient use of RF spectrum,
and long battery life. However, unlike conventional FM
systems, the design has eliminated the analog compandor and its artifacts.
Wide Deviation
±75 kHz deviation is used in the Digital Hybrid and 200
Series compatibility modes to dramatically improve
the capture ratio, signal to noise ratio and dynamic
range of the wireless system. This, in conjunction with
accurate input gain adjustment, produces outstanding
audio quality that rivals a hard wired connection.

Wideband Hand Held Transmitter
Pilot Tone Squelch
The benefit of the pilot tone squelch system is that the
associated receiver will remain muted until it receives
the pilot tone from the matching transmitter, even if a
strong RF signal is present on the carrier frequency
of the system. All Digital Hybrid Wireless® transmitters
use one of 256 different ultrasonic tones between 25
and 32 kHz in each standard frequency to operate the
receiver squelch.
The HHa is a wideband design that tunes across three
standard bands (up to 76 MHz). The pilot tone frequency is determined by the selected operating frequency
in 100 kHz steps. In other words, the same pilot tone is
used for all four frequencies within each 100 kHz step
of the tuning range. This preserves compatibility with
earlier Digital Hybrid products that tune across a single
frequency band (25.6 MHz).
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.
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.
Menu-Driven Control
A high-resolution LCD and control panel with membrane switches provide access to the menu-driven
setup. Transmitter RF power, high-pass filter, frequency
selection, backlight timeout, mute or talkback functions
and tuning modes are easily accessed.
Wideband Tuning Range
The transmitter can tune across bands of up to 76
MHz in either 100 kHz or 25 kHz steps.
Frequency Selection
Operating frequency is normally selected using a
receiver or analyzer to assess signals in the local environment to avoid interference. Once an interferencefree frequency is identified, the transmitter frequency is
set to match the receiver.
The LCD on the transmitter displays frequency in MHz
and with a two character hex code that is used on
most Lectrosonics receivers.
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 and HHVMC cardioid condenser capsules.
Capsules from several other manufacturers are also
available for use with the HH: those with a 1.25” x 28
thread pitch and three contact rings. Condenser or
dynamic microphone heads can be used with the HH,
depending on the user’s preference or the application.
IR (infrared) Sync
An IR Sync Port is used for quick setup with receivers
that offer this feature. Settings for frequency, step size
and compatibility mode are transferred from receiver to
transmitter via the IR ports.
Side Button Functions
A programmable switch on the side of the housing can
be configured as a mute/cough switch, to provide a
talkback function, a power switch, or be disabled.
The talkback function provides a communication
channel when used with a receiver equipped with this
feature, such as a Venue Wideband receiver with appropriate firmware. When pressed and held in, the side
switch re-directs the audio output to a different audio
channel on the receiver. As soon as the switch is released, audio is returned to the program channel.
The talkback function works only in the Digital Hybrid
compatibility mode.
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.

NOTE: It may take up to a minute or so for the
Updater to recognize the transmitter.
Step 5:
Put the transmitter in UPDATE
mode by simultaneously holding
UPDATE
down the BACK and UP arrow
buttons on the transmitter control
panel while powering it up.
Step 6:
Using a microUSB cable, connect the transmitter to
your PC.
Remove the lower housing of the transmitter by unscrewing it from the housing attached to the capsule
and pulling it straight off the body of the transmitter to
expose the circuitry. Spring-loaded ball detents provide
a “stop” with only the control panel exposed. Continue
to pull the lower housing farther to remove it. Simply
push the lower housing back onto the transmitter body
to re-install it.
WARNING: Do not disrupt the microUSB cable
during updating.
The Updater alerts with progress and completion.

Troubleshooting
SYMPTOM POSSIBLE CAUSE
TRANSMITTER WILL NOT POWER ON 1) Batteries are inserted backwards.
2) Batteries are dead, or too low to be used.
HH MODULATION LEDs OFF 1) Audio Gain set too low.
2) Battery is inserted backwards. Check LCD for power indication.
3) Mic capsule is damaged or malfunctioning. Contact the factory
for repair.
HH MODULATION LEDs GOOD BUT NO SOUND
1) Talkback function is engaged (release multi-function button).
See p. 11.
2) Receiver on wrong frequency or wrong band.
3) Receiver connected incorrectly to sound system.
4) Transmitter in standby mode.
RECEIVER RF INDICATOR OFF 1) Transmitter not turned on.
2) Transmitter is in “standby” (non-transmitting) mode. Check the
LCD for the antenna/transmission icon status.
3) Batteries are dead or installed backwards.
4) Receiver antenna missing, defective or improperly positioned.
5) Transmitter and receiver not on same frequency band.
Check labels on transmitter and receiver to be sure they are
operating on the same frequency band.
6) Make sure the transmitter and receiver frequency settings are in
agreement.
7) Operating range is too great.
8) Receiver antenna missing, incorrect frequency or disconnected.
NO SOUND BUT RECEIVER AUDIO LEVEL METER INDICATES SOUND
1) Receiver audio is muted. (Unmute receiver.)
2) Receiver audio output levels set too low.
3) Receiver audio output is disconnected or cable defective
or mis-wired.
4) Sound system or recorder input level is turned down.
DISTORTED SOUND 1) Transmitter Audio Gain set too high. Speak or sing into the
transmitter and check the Audio Level LEDs, Audio Level bar
graph in the transmitter
LCD and corresponding indicators on the receiver.
2) Receiver output level may be too high for the sound system or
recorder input.
3) Excessive wind noise or “breath pops.” Microphone may require
an additional wind screen.
4) Transmitter frequency setting is not correct (when used with
non-Digital Hybrid receiver).
5) Compatibility Mode mismatch between transmitter and receiver.
6) Mic capsule damaged or defective
HISS AND NOISE -- AUDIBLE DROPOUTS 1) Transmitter Audio Gain set too low. See page 10 for proper audio
gain setting.
2) Receiver antenna missing, defective or obstructed.
3) Operating range too great.
4) Interference may be present. Turn transmitter off and observe the
RF level indicator on the receiver. Change frequency if necessary.
5) Return attenuator control back to default setting of “F”, then
readjust audio gain per instructions on page 10
EXCESSIVE FEEDBACK 1) Transmitter Audio Gain set too high. Check level adjustment,
reduce receiver output level, or both.
2) Microphone too close to speaker system.
3) Move microphone closer to the user’s mouth and lower the
sound system volume.

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.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or
damage to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
