The SR consists of two separate receivers built into asingle, ultra compact housing with adapters for video camera receiver slots and for stand-alone use. Digital Hybrid Wireless™ technology provides superb, compandor- free audio quality and compatibility with other wireless systems. The RF performance is extremely stable over a very wide temperature range, making the receiver perfectly suited to the rough environmental conditions found in field production.
The front panel features a menu-driven LCD interface and four membrane switches which are used to view and alter settings. The main LCD window displays the pilot tone indicator, diversity activity, RF level, audio level and transmitter battery status for both receivers. A built-in spectrum analyzer scans across the tuning range of the receiver to locate RF signals in the vicinity find clear operating frequencies.
The two internal receivers can be operated separately, each using switching, antenna combining diversity, or in tandem with ratio diversity reception. Clear frequencies are easily found with the built-in RF spectrum scanner and graphical LCD. The audio outputs of the receivers can be mixed internally, or left separated for discrete recording tracks or external mixing. A variety of output adapters and mounting options are available for the in-slot or stand-alone versions. The SR/5P stand-alone version provides outputs via a 5-pin connector next to the control panel and the rear panel slot connector simultaneously. The unit is powered from an external 6 to 18 volt DC source.
The SMA Series family brings Digital Hybrid WirelessTM technology to miniature transmitters in several different configurations for essentially any wireless microphone application with a lavaliere microphone. The tiny size of the single battery SMa model makes concealment easy, yet with a full 50 mW output, it does not sacrifice performance.The dual battery SMDa model doubles the battery life of the SMa with the same feature set.
The SMQa offers 250 mW RF output power to extend operating range and the unique RM provides hands-free remote control for all three models. Switching power supplies throughout the design allow long battery life with NiMH batteries. Membrane switches and an LCD interface make setup quick and simple. Multiple functions are clearly marked on the panel, with on-screen prompts as reminders when another switch must be held or the selection is locked out. The innovative Servo Bias input provides a programmable, regulated voltage to accommodate a wide variety of electret microphones. It is no longer necessary to install resistive pads for some mics to prevent overload of the input stage, divide the bias voltage down for some low voltage mics, or reduce the limiter range at minimum gain settings. To simplify wiring connectors, a single configuration for all microphones is now available for Servo Bias inputs, and an alternate wiring configuration works well with Servo Bias and all other 5-pin inputs on Lectrosonics transmitters. Two bicolor LEDs make adjusting input levels for proper modulation easy and accurate. The splash-proof housings are machined out of solid aluminum, which is then plated with a superhard, non-corrosive coating. The units are equally at home in theatre, television and film where temperature and environmental extremes require superior performance under the most demanding conditions.
