Nady Systems UHF3LTSYSMU4, UHF 3 UB-3 Bodypack Microphone Transmitter, Headworn MIC/ Lavalier MIC

UB-3 BODYPACK MICROPHONE TRANSMITTER

1.Open the hinged BATTERY DOOR (23) and insert 2 fresh AAA ALKALINE BATTERIES into the BATTERY COMPARTMENT (24), observing the correct polarity. Fresh alkaline batteries can last up to 5 hours in use, but in order to ensure optimum performance, it is recommended that the batteries be replaced after 3-4 hours of use.

2.The UB-3 is equipped with an INPUT SELECTOR SWITCH (32) located under the cover for selecting the type of audio input you will be supplying to the transmitter. Select from the choice of three positions: INSTRUMENT (for guitar, bass, etc.)/

HEADWORN MIC/ LAVALIER MIC.

3.The UB-3 is provided with a 3.5 mm LOCKING JACK (26) for connecting the audio input selected. Connect either the INSTRUMENT CORD (34) or the HEADWORN MIC

(35)or LAVALIER MIC CORD (36) as desired, according to the input selected. (Note: Use only the input audio source as per the input selected with the AUDIO INPUT SELECTOR SWITCH or the audio will not be optimal–a muddy or distorted sound may result.) To secure the connection, turn the slip ring on the plug clock wise to thread

it on the jack. To unplug, reverse the process. Slip the transmitter into a pocket or CLIP

(33)it on to your clothes or instrument strap (if using the UB-3 as an instrument transmitter).

4.Turn on the UB-3 by sliding the audio MUTE SWITCH (27) to the ON position first. Then slide the POWER SWITCH (29) to the ON position. The battery indicator LED

(28)will give a single quick flash, indicating usable battery strength. In the case of dead or low batteries, the LED will either not go on at all or will stay on continuously, indicating that the batteries should be replaced with fresh ones. To preserve battery life, turn the transmitter off when not in use. The A AND/OR B DIVERSITY LED INDICATORS (13) on the UHF-3 receiver should now be lit, indicating a received signal from the transmitter.

5.Instrument Use

Secure the connection from the GT CABLE (34) by turning the slip ring on the plug into the transmitter clockwise to thread it on the jack. To unplug, reverse the process. Plug the 1/4” phone plug into the instrument. When ready to play, slide the audio MUTE SWITCH (27) to OFF position Adjust the volume of the receiver as per the Audio Output Instrument Connection section of the above UHF-3 receiver instruction.

(Note: The INPUT LEVEL CONTROL (25) is deactivated and not used when the UB-3 is in INSTRUMENT mode. Levels should be adjusted with the volume control of your instrument.)

The UHF-3 receiver is equipped with a 5 segment LED AF LEVEL DISPLAY (14). Occasional flickering of the top AF Peak LED indicator on loud inputs to the transmitter is normal. If this LED lights continuously, turn down the INPUT LEVEL CONTROL (25) on the UB-3 transmitter, or noticeable distortion may result.

(Note: Scratchy noises can sometimes occur when some electric guitars with dirty pots or connections are used with any wireless system. Therefore, the supplied INSTRUMENT CORD (34) has a factory installed capacitor inside the 1/4" plug. This capacitor provides first order filtering of the RF signal from the cord into the guitar and eliminates virtually all scratchy noises. Should your equipment still give you scratchy noises, we suggest these steps to eliminate them:

1)Make sure all guitar volume and tone pots are clean and all contacts are solid–this is very important.

2)A 47pf capacitor soldered across the hot to ground terminals of the guitar’s volume and tone pots will provide extra filtering.)

6.Microphone Use (with either a lavalier or headworn microphone)

Secure the connection from the LAVALIER (36) or HEADWORN MIC CORD (35) by turning the slip ring on the plug into the transmitter clockwise to thread it on to the jack. To unplug, reverse the process. To use the lavalier mic, attach it at chest level. Do not place it too close to the mouth–a distance of about six inches usually works best. To use the headworn mic, place it on the head and adjust the boom so that the mic is about one inch to the side of the front of the mouth. As the microphone cord also serves as the antenna, be sure to extend it fully. Rolling up or shortening the cord may reduce the effective operating range–keep it as straight as possible. When ready to speak, slide the audio MUTE SWITCH (27) to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above UHF-3 receiver instruction

[Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling and screeching) will be avoided. Please also note the pickup pattern characteristics of the microphone selected. Omnidirectional mics pick up sound equally from all directions, and are prone to feedback if not used carefully. Unidirectional mics are more resistant to feedback, but pick up sound sources best that are directly in front of the mic. Also, mics that are farther from the sound source, such as lavaliers, require more acoustic gain and thus are also more prone to feedback than close-source mics such as handheld or headworn models that are used close to the mouth].

For optimum performance, an INPUT LEVEL CONTROL (25) is provided. Adjust the gain by turning the control with a small screw driver. For lavalier mic use, it is recommended that the level be set at about 2/3 maximum. For headworn mic use, it may be advisable to turn the gain down somewhat, depending on the volume levels expected. In either application, experiment and set for maximum possible gain without audible distortion on the high level peaks. (Note: Turning down the gain too much can compromise the signal-to-noise and is not recommended.)

The UHF-3 receiver is equipped with a 5 segment LED AF LEVEL DISPLAY (14). Occasional flickering of the top AF Peak LED indicator on loud inputs to the transmitter is normal. If this LED lights continuously, but if the LED stays lit continuously, turn down the INPUT LEVEL CONTROL (25) on the UB-3 transmitter, or noticeable distortion may result.
