An interview from the 2018 National Association of Broadcasters Convention in Las Vegas with Karl Winkler of Lectrosonics. Well respected within the film, broadcast, and theatre technical communities since 1971, Lectrosonics wireless microphone systems and audio processing products are used daily in mission-critical applications by audio engineers familiar with the company's dedication to quality, customer service, and innovation. In this interview Karl talks with us about their Wideband Transmitters and The Duet Digital Wireless Monitor (IEM) System.
Lectrosonics introduces two new transmitters as the latest generation in the award-winning Digital Hybrid Wireless® SM Series product line: the “wide band” SMWB (single AA battery) and SMDWB (dual AA battery). The two new transmitters have a similar look and feel to previous SM Series units, but with several innovative new features, including the ability to either act as a transmitter or as a body-worn recorder, as well as wideband tuning.
As with current Lectrosonics transmitters, the SMWB and SMDWB units tune across 3 standard frequency blocks and come in several frequency ranges: A1 (470 – 537 MHz) and B1 (537 – 614 MHz) for the North American and export markets, and B2 (563 – 640 MHz) and C1 (614 – 691 MHz) for certain export markets. RF power for these models is selectable at 100, 50, or 25 mW (North American version) and 50 or 25 mW (certain export markets). The SMWB and SMDWB feature the standard TA5 connector with servo-bias mic input. This input is also found on all previous SM Series units and all current TA5 beltpack units like the LT and LMb. Any lavaliere microphones wired for these other Lectrosonics transmitters will also work on these new models.
The SMWB and SMDWB units can be configured either as a transmitter or a recorder, with files stored on Micro SD card memory, allowing use as body worn recorders. Audio files are recorded in the industry standard Broadcast Wave (.WAV) format at 24 bits, 44.1 kHz sample rate. The Micro SD memory card can also be used to update firmware in the field.
The SMWB and SMDWB also feature the same large, backlit LCD found on the latest Lectrosonics transmitters, including the LT, HHa, LMb and DBa. The new models also include an IR port to allow for quick setup when using any IR equipped receiver such as the LR, SRc or Venue 2. This allows for easy integration with a larger wireless system using Lectrosonics Wireless Designer™ software for frequency management and system monitoring.
The Duet Digital Wireless Monitor (IEM) System is comprised of the M2T dual-stereo half-rack transmitter and M2R diversity belt pack receiver.
The M2T half-rack transmitter houses two independent stereo transmitters. The analog input connectors are full size XLR/TRS combo types for balanced line level analog signals while the input preamp circuits use a special balanced amplifier with very high common mode rejection to minimize hum and noise. A version of the transmitter also offers a Dante Ultimo™ interface via dual RJ45 connectors, accepting Dante networked audio inputs and can cascade the digital stream to additional units via CAT6 cables. An Ethernet connection is also offered on an additional RJ45 for programming and control via Lectrosonics Wireless Designer™ software. The transmitter features a full color, backlit LCD for high visibility in any environment, while the chassis is all-metal and can be racked singly with an optional kit or in pairs using supplied rack mount hardware.
The M2R bodypack receiver features 24 bit digital audio for high resolution sound quality with wide dynamic range, low noise floor, and rock-solid stereo image. The headphone jack is fed from a high-quality stereo amplifier with 250 mW available to drive headphones or earphones to sufficient levels for stage performance or other noisy environments. A high-resolution, color LCD allows for a wide range of menu options, including precise limiter settings, using detailed graphics.
Both the M2R and M2T units have 2-way IR sync, so scan data from the receiver can be sent to the transmitter and thus onto the Ethernet network for use by Wireless Designer™ software for frequency planning and coordination purposes. Additionally, the system includes a FlexList™ mode, where a number of names and associated frequencies can be stored in the receiver. This way, a monitor engineer can quickly find and listen to any of the performers’ mixes on the stage.
