General Technical Description
Hand Held Transmitter
Introduction
The HH 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. Due to
the flexibility of digital signal processing, however, the
transmitter is also able to operate with Lectrosonics
200 Series, Lectrosonics 100 Series, IFB and certain
non-Lectrosonics analog receivers in special compatibility modes. (Contact the Lectrosonics Sales Department for a complete list of compatible receivers.)
Digital Hybrid 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 (also
called Digital Hybrid) 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 Digital Hybrid
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 Digital Hybrid 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 dynamic range
and signal to noise ratio.

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 transmitters use one of
256 different ultrasonic tones between 25 and 32 kHz
to operate the receiver squelch. The pilot tone frequency is chosen according to which of the 256 channels
has been selected by the frequency switch setting.
This ensures that all transmitters in a multi-channel
system have different pilot tone frequencies so that
even spurious RF from the wrong transmitters will not
open the receiver squelch.
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. Lithium batteries will provide over 8 hours of
operation. 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.
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.
Membrane switches on the control panel select 256
frequencies in 100 kHz steps or 1024 frequencies in
25 kHz steps over a 25.6 MHz range.
Output Isolator
The output circuit includes a special RF device called
an isolator. Its purpose is to block radio signals from
coming back into the transmitter final amplifier through
the antenna.
The isolator suppresses IM (intermodulation) that
can take place between two or more transmitters that
are in close proximity to one another (a few feet).This
form of IM is a particular concern in stage productions where the transmitters must operate very close
together. Isolators allow the use of higher transmitter
output power without sacrificing IM rejection.
Isolators are rarely found in wireless microphone
transmitters due to the high cost, but they are the best
solution to address multi-channel IM between multiple
transmitters.
Antenna
A newly designed helical antenna allows the mic to be
held in any position, since the user’s hands have little
or no effect on the radiated power.
Microphone Capsules
The HH handheld 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 Sync
The HH is equipped with an IR (infrared) port for use
with receivers that will be developed in the future. Settings such as frequency stored in the receiver will be
sent to the transmitter via the IR port. No such receivers are available as of the date of this writing.
Mute and Talkback Functions
A programmable switch on the housing (side switch)
can be configured as a mute switch or to provide a
talkback function for communication with the crew or
director/producer through a different audio channel.
As a mute switch, it works in a “push off/push on”
fashion as a toggle to disable and enable the audio
signal. Push to mute. Push again to restore audio. The
mute function defeats the audio in the transmitter, so it
works in all compatibility modes and will all receivers.
The talkback function provides a communication
channel when used with a receiver equipped with this
function, such as a Venue Wideband receiver with
firmware Ver. 5.2 or higher. 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.

Mic Capsule Adjustments
(EXPERT LEVEL ONLY)
Several special adjustments can be made on the
preamp circuit board under the windscreen. These adjustments significantly alter the gain and tonal quality
of the microphone, and are to be used only in special
circumstances.
Caution: Due to the high RF levels surrounding
the transmitter, the sound of the capsules may
be temporarily affected if the metal windscreen is
not in place. Always make the final decision about
sound quality with the windscreen in place.
Attenuator Adjustment
The HHC & HHVMC heads include an attenuator in
the preamp circuitry to provide an additional 15 dB of
headroom when needed for extremely loud voices.
The attenuator should ONLY be used when the normal
gain control is already turned all the way down and the
audio is still driving the preamp into significant limiting
where both -20 and -10 dB LEDs stay lit all or most of
the time during peaks in the audio.

The control is a 16 position switch that attenuates the
audio in 1 dB steps. It is marked 0 through F where F
is minimum attenuation and 0 is maximum attenuation. The switch operates much like a volume control in
that rotating it clockwise increases the loudness, and
counter clockwise decreases the loudness.
Attenuator switch set at F for normal operation.
IMPORTANT: Be sure to set the attenuator control back
to its original setting (“F”) for normal operation.
If adjustments are made for a particular situation and
the attenuator is not returned to its normal position, a
subsequent user may think the unit is malfunctioning or
has a poor signal to noise ratio.
These controls operate as standard tone controls in
that a counterclockwise adjustment cuts the response
in that band and a clockwise adjustment boosts the
response. In the photo above, all three controls are set
at “zero” with no boost or cut.
NOTE: Make sure the controls are set as shown
above, then complete the Gain Adjustment
covered on page 10 before making changes to
the tone controls.

About Setting Audio Gain
The two bicolor Modulation LEDs (located at the bottom of the control panel) provide a visual indication of
the audio signal level entering the transmitter.
The modulation
LEDs are oriented
and labeled to be
read when holding
the mic capsule in
front of your mouth.
The gain should be
set so that the -20
LED just turns red
on the loudest peak.
The LEDs will glow either red or green to indicate
modulation levels as shown in the following table.
Signal Level -20 LED -10 LED
Less than -20 dB Off Off
-20 dB to -10 dB Green Off
-10 dB to +0 dB Green Green
+0 dB to +10 dB Red Green
Greater than +10 dB Red Red
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.
1) With fresh batteries in the transmitter, power the
unit on into “standby” (no transmission) mode.
2) Press the MENU/SEL button once to enter the
setup menu. Use the UP/DOWN buttons to select
Gain. Press the MENU/SEL button again to enter
the setup screen.
3) Hold the microphone the way it will be used in
actual operation.
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.
5) Once the audio gain has been set, the signal can
be sent through the sound system for overall level
adjustments, monitor settings, etc. To do this, the
unit must be set to transmit (see Powering On
and Off, and the Standby Mode on page 7).
10
NOTE: Full modulation is achieved when the
-20 LED first turns red. 30 dB of clean limiting is
available above this point.

Mute is a “push on/push” off function that toggles on
and off each time the Side Button is pressed. The
mute function defeats the audio in the transmitter, so it
works in all compatibility modes and will all receivers.
Talkback is a “push to talk” function that is active only
while the button is pressed. The talkback function
provides a communication channel when used with a
receiver equipped with this function, such as a Venue
Wideband receiver with firmware Ver. 5.2 or higher.
When pressed and held in, the side button 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.
NOTE: The Talkback function is only available in
the 400/Hybrid compatibility mode. It will not allow
you to enable Talkback in any other mode.

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.
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.
