Polsen ULW-16 overview

  • 1Description

The Polsen ULW-16 is a 16-channel camera-mountable UHF wireless system designed to transmit audio up to 300'. It is engineered to be exceptionally quiet, and with many professional features like headphone monitoring, line input, and frequency agility, the ULW-16 is ideal for EFP (electronic field production), DSLR, and many other video applications. 

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.

Engineered for Versatility

Best-In-Class Sound Quality
The ULW-16 easily outperforms its competitors with a greater than 105 dB signal-to-noise ratio, and better than 95 dB of dynamic range for pristine audio transmission and output
Frequency-Agile System
The 16-channel ULW-16 wireless system allows operators to quickly and effortlessly switch channels in order to locate a clear channel
Headphone Monitoring with Level Control
Transmissions can be monitored at a comfortable level from the receiver's headphone output in real time, without the latency that often occurs when monitoring via a camera's headphone output
Omnidirectional Lavalier Microphone
The omnidirectional polar pattern is ideal for video applications because it offers flexible placement options, and allows for head movement without affecting the sound
Line-Level Output
The receiver features a line-level output for the best possible signal-to-noise ratio. Using the included 1/8" (3.5mm) male to XLR male cable, the ULW-16 receiver can be connected to a professional video camera, recorder, or other line-level device
Line-to-Mic Attenuator Cable
The included line-to-mic level-attenuator cable is designed to attach the output of the receiver to camcorders, DSLRs or other devices with a mic-level input
Variable Level Control
The variable level control on the transmitter assures that sufficient level is being transmitted to the receiver to achieve the best signal-to-noise ratio throughout the signal path
Portable Receiver
The receiver can be mounted onto a standard shoe mount of a DSLR or video camera
Compact and Lightweight
Weighing approximately 3 ounces, the transmitter can be easily concealed on a subject by attaching it with the included belt clip, or placing it in a pocket
Front-Panel Access to Batteries
Both the receiver and transmitter feature front-panel access to the battery compartment so you can change the batteries even when the system is counted and wired up
LED Indicators
The RF LED on the receiver illuminates indicating there is a signal on the selected channel. LED channel indicators make the channel number easy to see even in dim lighting conditions. The transmitter's TX LED glows red to indicate that the unit is transmitting
1/4"-20 Threaded Socket
The standard 1/4"-20 threaded socket provides a variety of mounting options
Included Accessories
The included tie clip provides a variety of discreet microphone-placement options and can be used to attach the microphone to a collar, necktie, or costume, while the included windscreen reduces wind noise and vocal plosives (pops). The integrated belt clip secures the transmitter to the talent and allows it to be discreetly hidden under a garment or costume, and the standard shoe mount with locking wheel easily and securely attaches to most cameras.
One-Way Communication Application
The ULW-16 can be used as a one-way voice-communication system for stage directions and talent cueing
Future Proof
The ULW-16 system operates in the UHF 500 MHz bandwidth assuring that it is "future proof" and meets current and known future FCC regulations.
Protective Carrying Case
The ULW-16 wireless system includes a sturdy protective carrying case making transport effortless. Inside, custom foam enclosures secure the components and protect them from impact, and solid external construction will withstand the rigors of road use

    Polsen ULW-16 reviews

    ULW-16 16-Channel Camera-Mountable UHF Wireless System with PL-4 Lavalier Microphone - (584.400 to 602.450 MHz) is rated 2.3 out of 5 by 9.
    Rated 1 out of 5 by from This product is unreliable I purchased this product to record slightly better audio than my camera mounted boom mic. It was reasonably priced at around $225. The first unit failed after only two uses. I tested the XLR connection into a ZOOM recorder the night before I was to use it, but the next morning, it didn't work, and shortly after that, the entire unit would not work. I had to go through the Gradus Group to have it covered under warranty. They were slow to respond, but eventually sent me a replacement unit. It didn't even last through one day of shooting before failing again. I would NOT recommend this product, and am likely to never buy Polsen brand again.

    Rated 2 out of 5 by from Not So Good... I use this mainly for interviews, all done within a controlled setting. Unfortunately, after making many adjustments and trying different things (pad, proximity of mic, etc.), I cannot get the audio from sounding as if it's peaking out (even thought it is far from peaking).

    Rated 5 out of 5 by from Great wireless system Very pleased with this wireless setup. The range outdoors in clear sight is great, I have tested it to over 400 ft in optimal conditions. I got this system because of the line in jack. I record lots of powersports races and I am able to get a line out from the announcer's sound system which I mix in to the camera. Otherwise it's pretty much impossible to record the announcer over the noise. I am also impressed with the lapel mic included- good sound for a budget system. Also the included padded case is a nice touch.

    Rated 4 out of 5 by from loud and clear it works great, easy to use and it will disconnect the receiver onces the transmitter is off you can control de volumen the mic cable seems a little thin, for my taste. It did nt broke but it seems dedicated. other than that looks fine
    Date published: 2016-06-02
    Rated 1 out of 5 by from COMPLETE GARBAGE! DO NOT BUY! Bought these and was within the factory warranty and quit working and B&H told the manufacturer was going to reach out to me and NEVER did. I took them to have fixed and they told me to throw them in the garbage. DO NOT BUY and the company will not respond. Can't believe B&H still carries these.

    Rated 3 out of 5 by from Decent Mic | Good performance This purchase was not bad at all, other than the cheaper built microphone provided with the unit comparing that with my son Seinheiser unit I was pretty much satisfy. But I can always buy another microphone to attach to this unit.

    Rated 1 out of 5 by from Broke In Less Than 14 Months Do not buy, they broke in the first 14 months.
