Being located directly across the Potomac River from Washington, DC, the production crew at the Signature Theatre knew very well what it meant to operate in a crowded RF environment, and turned to wireless system solutions from Lectrosonics.

With airports, radio and TV stations, the Pentagon, and countless other users of wireless frequencies all around, selecting a wireless microphone system that could readily adapt to the ever-changing frequency characteristics of the area was no small concern.

Matt Rowe, Signature Theatre’s resident sound designer, is responsible for all audio-related matters at the venerable theatre. A veteran audio professional who started his career as a recording engineer before transitioning to live sound reinforcement and who now marks his 12th season in theatrical sound design, Rowe described the audio challenges that routinely confront him at Signature Theatre.

“As a suburb of greater Washington, DC,” Rowe explains, “there are countless users of wireless equipment in our area. One day, a particular frequency may be available and then the next, it’s occupied. Being located in such a crowded RF environment, it was critical that we find a wireless system that not only delivered excellent sound quality, it also had to be able to adapt to changing RF conditions and, ideally, be able to expand the channel count should circumstances require.

“Equally important, we wanted transmitters that could readily be hidden among the talent’s wardrobe and they needed to be robust so as to withstand the bumps and drops that routinely occur in theatrical use.”

After consulting Bexel Broadcast Services in Washington, Signature Theatre purchased a 24-channel Lectrosonics wireless system, including 24 SMa super-miniature Digital Hybrid Wireless transmitters and four Venue Series receiver mainframes—each stocked with six VRT receiver modules.

The entire system uses Lectrosonics’ acclaimed Digital Hybrid Wireless technology, which uses a proprietary algorithm to encode 24-bit digital audio information with no compression and low distortion into an analog format that can be transmitted in a robust manner over an analog FM wireless link. The result is much higher dynamic range—free from sonic artifacts— than wireless systems using a compandor are able to offer. Equally noteworthy, the entire 24-channel system occupies only four rackspaces.

Signature Theatre’s new wireless system was first used on the production of Chess, which runs through late September. “Chess, featuring Broadway’s Jeremy Kushnier, Euan Morton, and Jill Paice, is a rock ‘n roll musical,” says Rowe. “We’re four weeks into production and we haven’t encountered a single RF issue. I’ve been particularly impressed with Lectrosonics’ SmartTune feature that enables me to easily find available frequencies at the touch of a button.”

SmartTune feature automatically scans all the available operating frequencies within the system’s frequency block range and then selects the frequency with the least amount of RF interference.

Rowe was equally complimentary of Bexel’s support throughout the initial setup process. “They really went above and beyond the call of duty,” he says. “In addition to helping us with frequency scans, they met with us on numerous occasions to go through the entire process of using the equipment—making certain that we fully understood its operation.”

With several weeks of use under their belts, Rowe offered these thoughts on the theatre’s new wireless microphone system, “The Lectrosonics equipment is performing just as we had hoped it would. The sound quality is first-rate and the small size of the transmitters makes them a perfect choice for use with wardrobe considerations. The Venue system’s modular frames facilitate expandability and make it easy to configure a system to one’s channel count requirement. The value and performance of this system made it a no brainer when it came to determining which manufacturer’s equipment to invest in. I’m confident we couldn’t have made a better purchase decision.”
