This B&H Kit combines a Lectrosonics SRc dual-channel, slot-mount receiver with two SMDWB bodypack transmitters, ideal for capturing two people speaking in ENG, EFP, motion pictures, or broadcast applications. It also comes with an SREXT adapter kit that allows you to use the SRc as a standalone in an audio bag or mounted on a camera.
The two transmitters feature TA5M 5-pin input connectors and are compatible with dynamic microphones, electret lavaliers, or line-level sources. They can also function as recording devices.
The SRc Dual-Channel Slot-Mount ENG Receiver from Lectrosonics consist of two separate receivers built into a single, ultra-compact housing with adapters for video-camera-receiver slots and for stand-alone use. They can be used when paired with a transmitter & microphone (sold separately) in various environments for ENG (Electronic News Gathering), EFP (Electronic Field Productions) and other audio applications.
Each receiver features Digital Hybrid Wireless technology that provides compandor-free audio quality and compatibility with other wireless systems. The RF performance is stable over a wide temperature range, making the receiver perfectly suited in rough environmental conditions.
The front panel has a menu-driven LCD interface and four membrane switches which are used to view and alter settings. In addition, the LCD window displays the pilot-tone indicator, diversity activity, RF level, audio level, and transmitter battery status for both receivers.
Furthermore, a built-in spectrum analyzer scans across the tuning range of the receiver and displays a histogram of RF activity across the band. Areas of RF activity are easily recognizable. The two internal receivers can be operated separately and both have switching, antenna-combining diversity, or in tandem with ratio-diversity reception.
Finally, a variety of output adapters and mounting options are available for camera-slot operation. The receivers are powered from an external 7 to 18 VDC source.
The Lectrosonics SMDWB is a wireless beltpack transmitter that can also act as a recording device, capturing audio onto microSDHC cards. Paired with a lavalier or dynamic microphone, the transmitter is suitable for ENG (Electronic News Gathering), EFP (Electronic Field Productions), interviews for broadcast TV, and more. It provides Digital Hybrid Wireless technology, combining 24-bit digital-audio processing with an analog FM radio link to give you the benefits of both worlds, such as fewer dropouts and audio artifacts while maintaining a robust range of operation. The transmitter is housed in a machined aluminum case, lending the unit a rugged and dependable shell. Its water-resistant control panel adds to its usability.
Operating in the A1: 470 to 537 MHz band, the transmitter offers selectable outputs to bolster its operating range, specifically among 25, 40, and 100mW. At lower values, the transmitter’s battery life will last longer; at higher values, the operating range is increased, though at the expense of battery life. Lightweight at 3.7 oz, the transmitter boasts settings making it compatible with dynamic microphones, electret lavaliers, and even line-level sources—so long as they can plug into the TA5M 5-pin input connector.
Input gain adjustment is possible in 1 dB increments for a total range of 44 dB. You’ll also note the low-pass filters, which can be switched to roll off at 30, 50, 70, 120, or 150 Hz to mitigate low-end disturbances. This input section also boasts servo-bias input circuitry proprietary to Lectrosonics, as well as an analog limiter controlled with DSP that, sitting ahead of the mic preamp itself, protects the audio path from overload. With its dual release envelope, it maintains acoustic transparency, even though it can achieve over 30 dB of gain reduction.
The SMDWB utilizes DSP that renders it suitable for use with all Lectrosonics Digital Hybrid receivers, though it is also backwards compatible for use with 100 and 200 series transmitters, IFB receivers, and various analog receivers from third-party manufactures. The unit is powered with two AA batteries, making use of switching power supplies to offer consistent voltages to its internal circuitry throughout its battery life.
Expanding the SMDWB’s functionality is its built-in recording capabilities, for use when transmission is simply not possible due to the conditions of the environment. The recorder operates at 24-bit/44.1 kHz, recording WAV files to microSDHC cards. As a transmitter, the SMDWB supplies an audio frequency range of 35 Hz to 20 kHz, though during recording, that lower value extends down to 20 Hz. You cannot use the transmitter and the recorder simultaneously, but it’s nice to have the option to select between the two. The transmitter includes a flexible steel-cable antenna.

The Lectrosonics SREXT is a connector panel adapter kit for the Lectrosonics SR Dual Slot-In Receiver. The kit is intended to provide the freedom of using the SR Receiver on standard, non slot-in mount scenarios. On the included connector panel are two TA3-male jacks for balanced output and a power jack with a locking connector. An unterminated power cable may trimmed to a desired length.
