The HH Digital Hybrid Wireless handheld transmitter
represents an elegant solution for a variety of wireless
microphone applications including live performance,
broadcast, AV rental and houses of worship. The HH
incorporates many advanced features to provide high-
quality speech and vocal reinforcement. Along with
providing peerless audio quality with wide frequency
response and dynamic range in native 400 Series mode,
the technology used in the HH includes compatibility
modes for Lectrosonics 200 Series, 100 Series and IFB
receivers, and some systems from other top manufactur-
ers. (Contact Lectrosonics for details.)
Interchangeable Capsules
Lectrosonics offers the HHC cardioid condenser capsule.
Thread-on capsules from other manufacturers using a
1.25” opening and 28 thread pitch can also be used,
including those from manufacturers such as EV, Shure®,
Heil SoundTM, Telefunken® and others.*
Digital Hybrid Wireless®
Digital Hybrid Wireless® is a revolutionary design
that combines digital audio with an analog FM
radio link to provide both outstanding audio quality
and exemplary, noise-free RF performance. Us-
ing a patented algorithm to encode 24-bit digital
audio information in the transmitter into an analog
format, the encoded signal is then transmitted over
an analog FM wireless link. At the receiver, the
signal is then decoded to restore the original digital
audio. This process eliminates compandor artifacts
and produces an audio frequency response flat to
20 kHz.

Selectable RF Transmission Power
The HH transmitter allows the user to select from among
two power settings† depending on the needs of the
situation. The lower RF power setting uses slightly less
current, thus battery life is enhanced. The higher power
setting provides greater range and resistance to drop-
outs. Selecting the RF power is accomplished using the
control menu.
Mute and Talkback Functions
The button on the back of transmitter below the head
can be used to actuate an audio mute condition. This
button can also be disabled using the control panel
inside the battery compartment. An alternative function
that can be actuated by this button is a talkback func-
tion. In this state, the transmitter sends a signal to the
Venue receiver when the button is pushed - the receiver
then switches the audio to a second output which can be
routed differently.
This function can be used for talkback, cueing or other
purposes depending on the application.
This functionality requires a Venue receiver
with firmware version X.XX or later.

Consumer Alert for US Users - FCC Order DA 10-92
Most users do not need a license to operate this wireless microphone system. Nevertheless,
operating this microphone system without a license is subject to certain restrictions: the system
may not cause harmful interference; it must operate at a low power level (not in excess of 50
milliwatts); and it has no protection from interference received from any other device. Purchasers
should also be aware that the FCC is currently evaluating use of wireless microphone systems,
and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC
(TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/
wirelessmicrophones. To operate wireless microphone systems at power greater than 50mW, you
must qualify as a Part 74 user and be licensed. If you qualify and wish to apply for a license go to:
http://www.fcc.gov/Forms/Form601/601.html
