• Lectrosonics - HMa Digital Hybrid Wireless® UHF Plug-On Transmitter


  • Accepts audio from any microphone or audio source with an XLR connector
  • Selectable 5, 15, 48 volt phantom power
  • 76 MHz tuning range in 100 kHz or 25 kHz steps for up to 3072 frequencies
    (941 band offers 695 frequencies over 19 MHz tuning range with 25 kHz steps)
  • Selectable 50/100 mW output power
  • Adjustable low frequency roll-off
  • Powered by two AA batteries
  • USB port for firmware updates
  • IR (infrared) port for fast setup
  • Solid machined aluminum housing

This unique plug-on transmitter design will ideally match any microphone or line level source via a standard XLR connector. Phantom power is selectable at 5, 15 and 48 volts, or can be turned off for use with dynamic microphones and line level signal sources.

The design includes a wide tuning range of up to 76 MHz, with tuning steps in increments of 100 kHz or 25 kHz, (19 MHz for block 941 version, for 695 frequencies).

Along with providing peerless audio quality with wide frequency response and dynamic range in Nu Hybrid mode, the technology used in the HMa includes compatibility modes for Lectrosonics Mode 3 and IFB receivers.

Included Accessories

  • 2 - AA Alkaline Batteries
  • 1 - HM Pouch (Part #PHTRAN3)

Capacity Specifications

Operating Frequency Range: HMa: Band A1: 470.100 - 537.575 Band B1: 537.600 - 607.950

Frequency Selection Steps: Selectable; 100 kHz or 25 kHz RF Power output: HMa: Selectable 100 or 50 mW HMa/E01: Selectable 25 or 50 mW HMa/E02: 10 mW HMa/E06: Selectable 50 or 100 mW EIRP HMa/E07-941: Selectable 50 or 100 mW HMa-941: Selectable 50 or 100 mW

Compatibility Modes: HMa: Nu Hybrid, Mode 3, IFB HMa/E01: Digital Hybrid, Mode 3, IFB HMa/E02: Digital Hybrid, Mode 3, IFB HMa/E06: Digital Hybrid,Mode 3, IFB HMa/E07-941, HMa-941: Digital Hybrid, 200 Series, 100 Series, Mode 3, Mode 6, Mode 7, IFB Pilot tone: 25 to 32 kHz; 5 kHz deviation (in the Digital Hybrid mode)

Frequency stability: ± 0.002%

Spurious radiation: HMa/E01/E02/941/X: 60 dB below carrier HMa: Compliant with ETSI EN 300 422-1 v1.4.2

Equivalent input noise: –125 dBV (A-weighted)

Input level: Nominal 2 mV to 300 mV, before limiting. Greater than 1V maximum, with limiting.

Input impedance: 1K Ohm

Input limiter: Dual envelope “soft” limiter; greater than 30 dB range

Gain control range: 55 dB; panel mounted membrane switches

Operating temp. range: Celsius: -20° - 40° Farenheit: -5° - 104°

Modulation indicators: Dual bi-color LEDs indicate modulation of -20, -10, 0, +10 dB referenced to full modulation

Audio Performance (overall system): Frequency Response: 35 Hz to 20 kHz (+/-1dB); Low frequency Roll-off: Adjustable for -3dB @30, 50, 70, 100, (120 or 150 Hz) THD: 0.2% (typ. 100 Hz to 20 kHz - see table) Signal to Noise Ratio (dB) at receiver output: SmartNR no limiting w/limiting OFF 103.5 108.0 NORMAL 107.0 111.5 FULL 108.5 113.0

Note: The dual envelope “soft” limiter provides exceptionally good handling of transients using variable attack and release time constants. Once activated, the limiter compresses 30+ dB of transmitter input range into 4.5 dB of receiver output range, thus reducing the measured figure for SNR without limiting by 4.5 dB.

Input Dynamic Range: 125 dB (with full Tx limiting) Controls & Indicators: • Power/Phantom “ON-OFF” • Phantom voltage selector • Audio input gain • LCD w/membrane switches • LED audio level indicators Audio Input Jack: Standard 3-pin XLR (female)

Phantom Power: 5V @ 18 mA max., 15V @ 15 mA max. and 48 V @ 4 mA max., plus “OFF” USB port: Used for firmware updates

IR (infrared) port: For quick setup by transferring settings from an IR enabled receiver

Antenna: Housing and attached microphone form the antenna

Battery: Two 1.5 Volt AA alkaline Battery Life (Duracell Ultra): AA alkaline; No Phantom Power: 5h 0m* AA alkaline; 48V Phantom Power: 3h 30m** * Tested with a dynamic microphone ** Tested with a Sanken CS1 for a phantom-powered microphone Weight: 6.7 oz (190 grams) without batteries

Dimensions: 4.25x1.62x1.38 inches 107.95x41.15x35.05 mm
