HHaLECTROSONICS, INC.4General Technical DescriptionIntroductionThe HHa handheld transmitter uses state-of-the-art Digital Hybrid Wireless® wireless technology, select-able output power and a versatile microphone capsule mounting system to meet the needs of audio profes-sionals and vocalists.The compandor-free Digital Hybrid audio chain pre-serves 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 ProcessorThe 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 ModesThe transmitter was designed to operate with Lec-trosonics 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 compat-ibility modes. (Contact the Lectrosonics Sales Depart-ment for a complete list of compatible 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 distor-tion 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 over-comes 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 com-pandor 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.Mic capsuleBias 5V +7VInput AmpInterfaceShunt LimiterMENU/SELBACKMUTEPOWERReference CrystalReference Crystal3 V BatteryVariable Switching Power SupplyHi.Lo Pass FilterDigital PotAudio LevelPhantom PowerAudio A-D Converter11001001D-A Converter11001001Control PanelMicroprocessorVoltage Controlled OscillatorFinal AmplifierFilter AmpEncoded Audio and Pilot ToneBicolor Modulation LEDsSwitching Power SupplyDigital Signal ProcessorPhase Locked LoopLCD
Wideband Hand Held TransmitterRio Rancho, NM 5Pilot Tone SquelchThe 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 block to oper-ate the receiver squelch.The HHa is a wideband design that tunes across three standard blocks (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 com-patibility with earlier Digital Hybrid products that tune across a single frequency block (25.6 MHz).Input Gain Range and Limiter45 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 be-fore the A-D converter. The limiter has a range of more than 30 dB for excellent overload protection. A dual re-lease envelope makes the limiter acoustically transpar-ent 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 LifeSwitching power supplies throughout the design allow over 5 hours of operation using two alkaline AA bat-teries. 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 ControlA high-resolution LCD and control panel with mem-brane 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 RangeThe transmitter can tune across band of up to 76 MHz in either 100 kHz or 25 kHz steps.Frequency SelectionOperating frequency is normally selected using a receiver or analyzer to assess signals in the local en-vironment to avoid interference. Once an interference-free 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.AntennaA newly designed helical antenna allows the transmit-ter to be held in any position, since the user’s hands have little or no effect on the RF output power.Microphone CapsulesThe 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) SyncAn 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 FunctionsA 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 ap-propriate 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 re-leased, audio is returned to the program channel.The talkback function works only in the Digital Hybrid compatibility mode.USB Port for Firmware UpdatesFirmware 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.

HHaLECTROSONICS, INC.18Service and RepairIf your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equip-ment needs repair. Make sure you have followed the setup procedure and operating instructions. Check the inter-connecting 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 con-nection, 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 read-justment. 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 mod-est 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 RepairFor 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: Telephone: Lectrosonics, Inc. Lectrosonics, Inc. (505) 892-4501 PO Box 15900 581 Laser Rd.
