General Technical Description
Introduction
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.

Rechargeable batteries give little or no warning when nearing depletion. If you use rechargeable batteries in the HH, we recommend trying fully charged batteries first, noting the length of time that the batteries will run the unit, and in the future using somewhat less than that time to determine when the battery needs to be replaced. The Venue and other receivers from Lectro­sonics offer a timer function to assist in this process.

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).

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.

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.
