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 IFB receivers in a special compatibility mode. Bias 5V Phantom Power Mic capsule Interface Input Amp Digital Pot 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. +7V Hi.Lo Pass Filter Audio Audio Level A-D Converter D-A Converter 11001001 11001001 Encoded Audio and Pilot Tone Filter Amp Variable Switching Power Supply Digital Signal Processor Shunt Limiter 3V Battery Switching Power Supply Microprocessor Reference Crystal LCD BACK MUTE POWER Bicolor Modulation LEDs Control Panel MENU/SEL Phase Locked Loop Reference Crystal Voltage Controlled Oscillator Final Amplifier LECTROSONICS, INC. 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. Digital Hybrid Wireless® transmitters use one of up to 256 different ultrasonic tones between 25 and 32 kHz in each standard frequency to operate the receiver squelch. The pilot tone frequency is determined by the selected operating frequency in 100 kHz steps. The same pilot tone is used for all four frequencies within each 100 kHz step of the tuning range. 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. Antenna A uniquely 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. When pressed and held in, the side switch redirects 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. 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. Rio Rancho, NM HHa A mic capsule is threaded onto the body of the transmitter in the direction shown. Do not overtighten it. Mechanical Assembly The lower housing opens by rotating it in the direction shown. After the threads are disengaged, pull the housing downward until it engages the detent that holds it open. The threaded interface is a 1.25” diameter opening with 28 threads 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. HHC Lectrosonics cardioid electret Capsule Installation HHVMC Lectrosonics cardioid electret with VariMic preamp Along with these two models from Lectrosonics, a variety of different capsules with a common 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. lectrosonics.com listed on the HH transmitter page. *All product names are trademarks of their respective owners, which are in no way affiliated with Lectrosonics. LECTROSONICS, INC. Wideband Hand Held Transmitter Battery Installation To insert batteries, close the eject lever and insert the upper contacts first (closest to the mic capsule). Polarity is marked on the label in the bottom of the battery compartment.

The countdown from 1 through 3 will appear on the LCD, followed by a display of the model, firmware version, frequency band and compatibility mode. The contacts are very tight to prevent the batteries from “rattling” as the transmitter is being handled. IR Sync The IR SYNC (infrared sync) port is used with receivers that offer this feature. Settings stored in the receiver for frequency, step size and compatibility mode are transferred to the transmitter via the infrared ports. To use this feature, open the housing on the transmitter to expose the control panel. Hold the transmitter near the receiver (less than 3 feet away) so the IR ports face each other. The transfer is triggered by a switch on the receiver. The LCD on the transmitter will display a message confirming that the settings were successfully transferred, or an error message that identifies the problem that occurred.

This is useful, for example, when the transmitter is in the “standby” mode during setup, allowing it to be turned on for normal operation without having to cycle the power. StepSiz TxPower Phase Rf On? This menu item can also be used to change the transmitter to the “standby” mode with the RF output turned off for additional setup. Default The default setting simple returns the transmitter back to the factory settings and any of the menu items can be readjusted from that default point. TxPower Phase Rf On? Default Default settings No Yes The audio level is shown by LEDs and in the LCD screen. The gain should be set so that the -20 LED just turns red on the loudest peak (the onset of limiting). Rf On? No Yes -20 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 and 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 and 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 8). NOTE: Full modulation is achieved when the -20 LED first turns red. 30 dB of clean limiting is available above this point. 10 LECTROSONICS, INC.

Rio Rancho, NM 17 HHa 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. Mailing address: Shipping address: Lectrosonics, Inc. Lectrosonics, Inc. PO Box 15900 581 Laser Rd.
