THANK YOU FOR CHOOSING POLSEN.
The Polsen ULW-16 and ULW-16-HL are 16-channel camera-mountable UHF wireless systems
designed to transmit audio more than 100 feet. Engineered to be exceptionally quiet, and with
many professional features like headphone monitoring, line input, and frequency agility, both
systems are ideal for EFP (electronic eld production), ENG (electronic news gathering), DSLR, and
other video applications that can benet from the advantages of a user-friendly wireless system.
With its impressive 105 dB signal-to-noise ratio, the ULW-16 and ULW-16-HL deliver pristine
audio transmission for broadcast-quality recordings. You can choose from 16 channels to avoid
interference. Up to ve systems (or more under optimum conditions) can be used simultaneously
in the same location.
The receiver features a 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.
The ULW-16 system includes a transmitter that features a variable-level control that lets you
adjust the transmission level. It’s also equipped with a line input that enables the transmission
of such devices as an audio mixer. The system offers a choice of omnidirectional lavalier
microphones: the 0.20” PL4 lavalier providing exible positioning options, and the 0.14” PL5 mini
lavalier for more discreet microphone placement. Both provide excellent wind and noise rejection.

The included windscreen can be used to reduce vocal plosives (pops) and wind noise,
and the mics can be readily placed on a collar, necktie, or costume with the included
tie clip.
The ULW-16-HL system includes a sturdy, broadcast-quality handheld transmitter
ideal for a variety of applications such as news reporting or recording interviews.
It features a mic capsule with a cardioid polar pattern ideal for video applications
where background noise can be problematic such as outdoors, on trade show oors,
or at live events. The channel selector button makes it easy to switch between the
unit’s 16 UHF channels, effectively minimizing frequency interference. An integrated
foam windscreen under the mic grille serves the dual purpose of minimizing vocal
pops and wind noise, and protecting the mic capsule from moisture.
Both systems operate in the UHF 500 MHz bandwidth assuring less susceptibility to
interference than VHF systems and greater reliability at longer distances. Operating
in this bandwidth also ensures that the ULW-16 and ULW-16-HL systems are “future
proof” and meet current and known future FCC regulations.
With features like easy-to read LED indicators, front panel access to batteries, and
included accessories, Polsen’s ULW-16 and ULW-16-HL are designed with the user
in mind. Professionals and enthusiasts alike will benet from its ease of operation,
durability, sensible ergonomics, and portability.
Please read and follow these instructions and keep this manual in a safe place.

INSTALLING BATTERIES
The transmitter, receiver, and handheld transmitter are each powered by two AA batteries (not included). To install the batteries,
follow these steps:
Transmitter and Receiver
1. Make sure the unit is turned off by rotating the control knob to the OFF position.
2. Gently squeeze the battery compartment panel by the arrows on both sides
and pull out to swing the panel open.
3. Insert fresh batteries in the proper orientations.
4. Close the panel completely so it locks into place.
Tip: You can use rechargeable AA batteries with the receiver and transmitter and recharge them by inserting them into the Polsen
ULW-BBCH charger (sold separately). Use only rechargeable batteries with the charger. Do not attempt to charge standard batteries
– this may result in damage to the unit and void the warranty.
Handheld Transmitter
1. Unscrew the battery compartment cover exposing the battery
compartment.
2. Insert fresh batteries according to the orientation diagram inside the
compartment.
3. Replace the battery cover by screwing it rmly back into place.

OPERATING INSTRUCTIONS
Before you connect the system to your camera and talent, you should test and set initial parameters as detailed below:
Test for interference
1. Test your RF environment before recording. To do this turn on only the receiver. If the RF LED is illuminated, then there is
interference on this channel. Change the channel and repeat until you nd a channel that is free of interference.
Connect transmitter and receiver
ULW-16
1. Connect the included lavalier microphone to the transmitter’s microphone input or plug in a line-level source such as an audio
mixer to the transmitter’s line-level input.
Note: If you are connecting the receiver to a sound system, mute the sound system. Do not monitor with headphones at this stage.
Anytime you are changing channels, remove your headphones and mute connected sound systems to avoid audible RF noise bursts.
2. Turn on the transmitter and the receiver by rotating the level controls clockwise. You should feel the click and see the channel
indicator LED light up.
3. Use the channel selector buttons to set the transmitter and receiver to the same channel. If you are experiencing interference or
noise on one channel, try a different channel. If you are using multiple ULW-16 wireless systems, make sure each system is set
to a different channel – at least three channels apart as a guard band.

4. With the headphone volume set to a low level, plug in an earpiece or headphones to the receiver and gradually raise the level to
a comfortable volume for monitoring the transmission.
5. Gradually turn up the transmitter’s level control and make sure a sufcient level is being transmitted to the receiver. Setting to
the level target mark will generally ensure a good signal. The objective is to transmit the highest possible level without distortion
for the best signal-to-noise ratio throughout the signal path.
ULW-16-HL
1. Turn on the handheld transmitter by moving the power switch to the ON position. The LCD display will illuminate showing the
selected channel and battery icon.
Note: If you are connecting the receiver to a sound system, mute the sound system. Do not monitor with headphones at this
stage. Anytime you are changing channels, remove your headphones and mute connected sound systems to avoid audible RF
noise bursts.
2. Set the handheld transmitter and the receiver to the same channel. If you are
experiencing interference or noise on one channel, try a different channel.
To select the channel on the ULW-16-HHT, follow these steps:
a. Remove the battery compartment cover.
b. Press and hold the SELECT button. The channel indicator on the LCD
display will begin to blink.
10
c. Change the channel with short presses of the SELECT button until the desired channel is selected. The channel indicator will
continue to blink for 10 seconds and then stop indicating that the channel has been selected.
d. Replace the battery compartment cover.
Note: If you are using multiple ULW-16 or ULW-16-HL wireless systems, make sure each system is set to a different channel—at
least three channels apart as a guard band.
3. With the headphone volume set to a low level, plug an earpiece or headphones into the receiver and gradually raise the level to
a comfortable volume for monitoring the transmission.
4. Adjust the audio output level on the receiver or the input level on your input device as necessary to make sure a sufcient level
is being recorded. The objective is to transmit the highest possible level without distortion for the best signal-to-noise ratio
throughout the signal path.
Important: It is not recommended to adjust the gain setting of the handheld transmitter. The gain is factory preset to the ideal
setting. Any volume adjustments should be made on the receiver or on the input device.
5. Once you have determined that the transmission quality and level are good,
mount the receiver.
Note:When holding the ULW-16-HHT handheld transmitter, hold it in the middle
of the transmitter body, not at the end where the antenna is located. Covering the
antenna with your hand will degrade the transmission quality.
