INS TALLING BATTERIES

The transmitter, receiver, and handheld transmitter are each powered by two AA batteries. To install batteries, follow these steps:

1. Make sure the unit is turned off.

2. Gently remove the battery compartment cover by pressing on the cover and sliding it in the direction of the arrow.

3. Insert two fresh AA batteries in the proper orientations.

4. Close the compartment by pushing the cover so it locks into place.

Rechargeable Batteries: You can use rechargeable AA batteries with the receiver and transmitter and charge them by inserting both units into the Polsen ULW-96-BBCH charger (sold separately). When using rechargeable batteries with the handheld transmitter, you can charge them by plugging the unit into the Polsen ULW-HCH charger (sold separately).

11

Important! Use only rechargeable batteries when charging. Do not attempt to charge alkaline batteries—this can damage the unit

and void the warranty.

Battery Power Icon: The battery power icon on the LCD ( ) indicates the remaining battery power. When only one bar appears in

the icon ( ), battery power is low and we recommend changing or recharging the batteries. When the battery power icon is empty

and blinking ( ), the batteries are almost out of power, and you will need to change or recharge the batteries at this point.

Note: Insufficient battery power can decrease the ULW-96-V2’s ability to transmit and receive. Be prepared: make sure your

batteries start out with a full charge when using this system, and always carry spare batteries.

OPERATING INS TRUCTIONS

Testing the RF Environment

Before you hook up the ULW-96-V2 to your camera and talent, it is important to test and set initial parameters in order to reduce

the possibility of RF interference or noise:

1. Turn on the receiver. The RF LED will glow red as the receiver turns on.

2. If the RF LED changes from red to green, there is interference on this channel. Change the channel, repeating as necessary until

you find a channel that is free of interference.

12

Connecting the Transmitter and the Receiver

The ULW-96-V2 includes a PL-5 omnidirectional lavalier microphone that plugs securely into the transmitter’s mini-XLR microphone input to prevent accidental disconnection. The omnidirectional polar pattern offers flexible positioning options and allows for head movement without affecting the sound. It can be readily placed on a collar, necktie, or costume via the included tie clip.

In addition to the microphone input, the transmitter is equipped with a line-level input that enables devices such as an audio mixer, camera output, or audio recorder output to be transmitted to the receiver. This advanced feature provides added flexibility that professionals rely on.

To connect the transmitter and the receiver, follow these steps:

1. Connect the included lavalier microphone to the transmitter’s microphone input or plug a line-level source into the transmitter’s line 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.

3. Set the transmitter and the receiver to the same channel. If you are experiencing interference or noise on one channel, try a different channel (for the transmitter, see 8. Set button on page 7 of the Overview).

13

Note: If you are using multiple ULW-96-V2 wireless systems, make sure each system is set to a different channel—set the channels at least 300 kHz apart to reduce the chance of intermodulation.

4. With the headphone volume low, plug your headphones into the receiver and gradually raise the level to a comfortable volume for monitoring the transmission.

5. Start with the transmitter’s sensitivity-control switch on “Mid” and adjust as necessary to make sure an ample level is being transmitted to the receiver. The objective is to transmit the highest possible level without distortion for the best signal-to-noise ratio throughout the signal path.

6. Once you have determined the transmission quality and level are good, mount the receiver and transmitter.

Connecting the Handheld Transmitter and the Receiver

The handheld transmitter’s capsule has a wide cardioid pattern for ample off-axis response. This helps to clearly capture your subject’s voice and to reduce unwanted ambience. The handheld operation is ideal for on-camera applications such as reporting, event coverage, and other situations where a lavalier microphone is impractical, like interviewing multiple people.

To connect the handheld transmitter and the receiver, follow these steps:

1. Turn on the handheld transmitter and the receiver.

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.

14

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.

Note: If you are using multiple ULW-96-V2 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 low, plug your headphones into the receiver and gradually raise the level to a comfortable volume for monitoring the transmission.

4. Adjust as necessary to make sure an ample level is being transmitted to the receiver. The objective is to transmit the highest possible level without distortion for the best signal-to-noise ratio throughout the signal path.

5. Once you have determined the transmission quality and level are good, mount the receiver.

Note: When holding the handheld transmitter, hold it by the body of the transmitter. Holding the antenna will degrade the transmission quality.

15

MOUNTING THE ULW-96-V2

Both the receiver and the transmitter mount via a two-way belt clip, allowing you to attach them upside-down. Being able to mount the body-pack at a variety of angles is helpful when multiple units are in use, especially when on the same person, as it reduces the risk of intermodulation.

Note: When manipulating the belt clip, be careful not to bend it out of shape.

Receiver

Shoe adapter: The receiver comes with the shoe adapter pre-attached. A 1/4"-20 threaded socket in the shoe adapter allows for additional mounting options.

To mount the receiver to your camera:

1. Loosen the adapter’s locking wheel and slide the mounting foot all the way into your camera’s shoe mount. Make sure to position the receiver so the antenna doesn’t enter your image frame.

2. Tighten the locking wheel until secure.

3. Use the included 1/8 in. (3.5 mm) audio cable to connect the receiver’s audio output to your camera’s microphone input.

To remove the shoe adapter:

1. Push outward on the belt clip at one of the hinges so one side of the clip pops out.

2. Remove the shoe adapter.

3. Reinsert the belt clip.

16

To reattach the shoe adapter:

1. Align the shoe adapter with the belt clip. The slot should line up with the bottom of the belt clip.

2. Insert the two-way belt clip into the body pack, one hinge at a time.

3. If necessary, adjust the adapter under the belt clip.

Reorienting the Belt Clip: The ULW-96-V2’s belt clips can easily be removed and reattached to the body pack so you can mount it

upside down. To reorient the belt clip, follow these steps:

1. Push outward on the belt clip at one of the hinges so one side

of the clip pops out.

2. Push the belt clip out from the other hinge to completely

remove the clip from the body pack.

3. Realign the belt clip with the body pack, making sure the clip is

facing the desired direction.

4. Insert the two-way belt clip into the body pack, one hinge at

a time.

17

Transmitter

1. Use the integrated belt clip to secure the transmitter to your talent.

2. Use the included tie clip to place the microphone on your talent.

3. If you are connecting to a line-level source, use an appropriate cable to connect to the Line In jack.

Note: The line-level input overrides the microphone input.

The receiver’s RF light will glow green when the unit is receiving a strong radio frequency signal.

S TAGE DIRECTION AND TALENT CUEING

The ULW-96-V2 can also be used as an impromptu one-way voice communication system for stage directions and talent cueing. In this case, your talent will operate the receiver instead of the transmitter, and monitor via an earphone (not included) plugged into the headphone output. The offstage instructor can dictate directions into the microphone/transmitter unit from a remote location, or send the cues from a broadcast mixer or interruptible feedback (IFB) system via the line input on the transmitter.

USING MULTIPLE UHF WIRELESS S YS TEMS

Since the ULW-96-V2 has 96 channels to choose from, multiple transmitters and receivers can be used in the same location simultaneously (up to eight). Each system that is added in simultaneous operation increases the potential for intermodulation, therefore more attention to the RF environment is needed. Each time you add a system, check all of the systems to make sure the system you added is not causing new interfearence. A good rule of thumb is to keep 300 kHz between systems.

18

TROUBLESHOOTING

Because of the widespread use of wireless technology, many RF signals pervade our environment. This can sometimes make it challenging to work with a wireless system like the ULW-96-V2. Each system that is added in simultaneous operation increases the potential for intermodulation and requires more diligence in RF planning and management. In some cases, you may be doing everything correctly and still be experiencing some difficulties. Included in this troubleshooting guide are some tools and tips for dealing with RF signals and interference.

Problem Possible Cause Solution Comment

The audio is noisy or distorted. This can include drop outs, white noise, bursts, pops, and clicks.

RF interference Try a different channel. Make sure both units are on the same channel.

Try to position the antennas at a 45° angle in relation to each other.

There can be a lot of RF interference outdoors. Try moving indoors, where there is less RF interference.

Keep the units’ antennas at least 2 ft. (0.6 m) away from conductive objects like metal and water. Overhead telephone lines, fluorescent lighting, and metal fences can all cause interference.

Turn off all nearby computers and mobile phones.

RF planning and management is important when using a UHF system. Test your RF environment before recording. To do this, turn on only the receiver. If there is noise or the RF LED is glowing, then there is interference on this channel and you should avoid using it.

Refer to www.fcc.gov/fcc-bin/audio/tvq.html to find out what frequencies are being used in your area by radio and TV stations, so you can avoid these frequencies.

The batteries are weak.

Replace or recharge the batteries in the receiver and transmitter.

Make sure to bring extra batteries with you.

You should replace the batteries on every shoot.

Rechargeable batteries will save money over time.

19


The audio is noisy or distorted. This can include drop outs, white noise, bursts, pops, and clicks.

The RF signal is weak.

Make sure there is an unobstructed line of sight between the receiver’s and the transmitter’s antennas. Keep in mind that your body, clothes, and onstage sets are possible obstructions.

Make sure the receiver and transmitter are within the 250 ft. (76.2 m) range.

If there are obstructions, you may need to move closer.

Intermodulation distortion

If the transmitter antennas are too close on multiple systems, they can cause intermodulation distortion between systems. Make sure the antennas are at least 3 ft. (0.9 m) away from each other.

On a single system, the transmitter and receiver antennas should be at least 8 ft. apart at all times.

The input level on the camera, recorder, or mixer is too high.

Turn down the audio input level on your camera or recording device. Lower the audio output level on the receiver.

Turn down the gain on your mixer.

If there is no adjustment on the device, and the level is still too high, adjust the microphone level on the transmitter. Keep this level as high as possible without distortion.

Make sure the talent is aware of the receiver and knows not to change the controls unless instructed otherwise.

Make note of your level settings before recording.

20


The unit will not turn on.

The batteries are dead.

Replace or recharge the batteries. Make sure to bring extra batteries with you.

There is no audio or the audio is intermittent.

The batteries in one of the units are dead.

Replace or recharge the dead batteries in the proper unit.

Make sure to bring extra batteries with you.

The audio cable is unreliable, or the cable or microphone is unplugged.

Check the audio cable to make sure it is reliable and is not shorting.

Check all cables to make sure they are completely plugged into the proper inputs.

The line source is off or not playing back audio.

If you are transmitting a line-level signal, make sure there is audio coming out of the line-source device.

The line-level input overrides the microphone input.

If you want to record via the microphone input, make sure there is nothing plugged into the line-level input.

The audio levels are too low.

Turn up the microphone level on the transmitter. Make sure it’s not set to Mute.

Adjust the headphone level on the receiver and listen to make sure the signal is transmitting.

Turn up the input levels on your camera, recording device, or mixer.

21


There is no audio or the audio is intermittent.

The transmitter and receiver are set to different channels.

Make sure the transmitter and receiver are set to the same channel.

One of the units is not turned on.

Make sure the transmitter, receiver, and all other devices in your audio chain are turned on and configured to the proper settings.

Too much ambience is being picked up.

When using an omnidirectional microphone like the one included with this system, the microphone may be picking up too much ambience.

Make sure the microphone is as close as possible to the subject.

Approximately 6 in. (15.2 cm) from the subject is usually good microphone placement, but you may need to experiment.
