With its impressive 105 dB signal-to-noise ratio, the ULW-16 delivers pristine audio transmission for broadcast-quality recordings. It has 16 channels to choose from to help avoid interference. Up to five systems (or more in optimum conditions) can be used simultaneously in the same location.

The transmitter features a variable-level control that adjusts the level of transmission. It’s also equipped with a line input that enables the transmission of devices such as an audio mixer. The receiver features an 1/8″ line output and included XLR cable for professional cameras. It also includes a cable for DSLR and consumer camcorders that have a 1/8” mic input. A headphone jack and volume control allows you to monitor the transmission signal in real time at a comfortable volume.

This ULW-16 system includes a PL-4 omnidirectional 0.20″ lavalier microphone for flexible positioning options and excellent wind-noise rejection. The included windscreen can be used to reduce vocal plosives (pops) and wind noise.

The system operates in the UHF 500 MHz bandwidth, assuring that it is “future proof” and meets current and known future FCC regulations.

With features like easy-to-read LED indicators, front-panel access to batteries, and included accessories to support operation, Polsen’s ULW-16 is designed with the user in mind. Professionals and enthusiasts alike will benefit from its ease of operation, sensible ergonomics, and portability.
