Lectrosonics SMWB Miniature Wideband Transmitter, A1 470.100 - 537.575 MHz

Lectrosonics SMWB Miniature Wideband Transmitter, A1 470.100 - 537.575 MHz To meet the demands for a variety of RF environments and applications, the “WB” series SM transmitters offer selectable output power of 25, 50 and 100 mW (25 and 50 mW for export versions). With higher power output, the operating range is improved, or, a more secure link can be relied upon for high RF noise environments. Battery life is unchanged with the different RF power selections. The transmitters offer hands-free setup and adjustment using audible tones. They can be put to sleep to conserve battery power during setup while buried inside costuming, then awakened for normal operation when the production begins. Other features include input gain adjustment in 1 dB increments over a 44 dB range and adjustable low-frequency audio roll-off for 3 dB down points at 35, 50, 70, 100, 120 or 150 Hz to control subsonic and very low-frequency audio content. Key Features Ultra-lightweight, corrosion resistant housing Water resistant seals for use in damp environments LCD interface with lockout option Programmable compatibility modes for use with a wide variety of different receivers Servo Bias input circuitry IR (infrared) port for fast setup Covers 3 frequency blocks (export versions cover 3 frequency blocks) Update firmware in the field via Micro SD card reader Alternate use as a recorder on an internal microSDHC memory card Technical Specifications Operating frequencies Band A1 470.100 - 537.575 Band B1 537.600 - 607.950 Channel Spacing Selectable; 25 or 100 kHz RF Power output 25, 50 or 100 mW Compatibility Modes Nu Hybrid, Mode 3, IFB Pilot tone 25 to 32 kHz Frequency stability ± 0.002% Spurious radiation Compliant with ETSI EN 300 422-1 Equivalent input noise -125 dBV, A-weighted Input level If set for dynamic mic, 0.5 mV to 50 mV before limiting Greater than 1 V with limiting If set for electret lavaliere mic, 1.7 uA to 170 uA before limiting Greater than 5000 uA (5 mA) with limiting Line level input, 17 mV to 1.7 V before limiting Greater than 50 V with limiting Input impedance Dynamic mic, 300 Ohms Electret lavaliere, Input is virtual ground with servo adjusted constant current bias Line level, 2.7 k ohms Input limiter Soft limiter, 30 dB range Bias voltages Fixed 5 V at up to 5 mA Selectable 2 V or 4 V servo bias for any electret lavaliere Gain control range 44 dB; panel mounted membrane switches Modulation indicators Dual bicolor LEDs indicate modulation -20, -10, 0, +10 dB referenced to full modulation Controls Control panel w/ LCD and 4 membrane switches Low frequency roll-off Adjustable from 35 to 150 Hz Audio Frequency Response 35 Hz to 20 kHz, +/-1 dB Total Harmonic Distortion 0.2% typical (400 Series mode) Audio Input Jack Switchcraft 5-pin locking (TA5F) Antenna Flexible, unbreakable steel cable.
