INTRODUCTION

Thank you for purchasing a Nady UHF-3 Diversity Wireless Microphone System and congratulations on your choice. The UHF-3 is loaded with top professional operating features and is the best performance and price value available in UHF diversity wireless systems.

USING THIS MANUAL

This booklet gives instructions for the operation of the UHF-3 wireless, including handheld, instrument, lavalier, headmic and plug-in transmitter systems. Please read the instructions for your system completely before operating unit.

This manual will first list the features of the UHF-3 and then will take you step by step to show you how to operate your new system. After reading the receiver instructions, turn to the section of the booklet that covers the type of transmitter used with your new system. Each section will give you detailed operating instructions. Also included in this manual are system specifications and servicing information.

UHF-3 RECEIVER

1. Rackmounting the Receiver

There are 2 options available for rackmounting the UHF-3 receiver: singly or side-by- side with another UHF-3 Series receiver.

a.Single mounting: Remove the receiver SIDE MOUNT CLIP (1) from each side of the receiver (as shown) and slide in the optional ERM-3 RACK EARS (2).

b.Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (1) from both UHF-3 receivers, join the two receivers with the EJC-3 JOINING CLIP

(3) and attach the ERM-33 RACK EARS (4) as shown. (Note: Do not mount

the receiver in a rack directly above an amplifier or other source of high heat – this could degrade the performance of the UHF-3. Always ensure adequate airflow and heat dissipation in any rack configuration.)

2. Powering the Receiver

Plug the 12V AC/DC ADAPTER (5) provided into the DC INPUT JACK (9) on the back of the receiver. Then plug the power supply into an AC outlet. (Note: Any 12V DC source with 400mA capability can also be used.) Press the POWER SWITCH (11) once to turn on the receiver. The POWER ON LED (12) will now light and the receiver is operational.

3. Antennas

The UHF-3 receiver is supplied with TELESCOPIC ANTENNAS (15). These should be extended fully to obtain maximum range. Optimal antenna position is 45 degrees from the receiver (at 90 degrees from each other). For maximum range, it is always best to maintain a line of sight (no obstructions) between the receiver antennas and the transmitter at all times whenever possible.

4. Mute (Squelch) Adjustment

In normal operation, the SQUELCH CONTROL (6) should be set fully clockwise to the factory preset RF level (Max. Sens.). However, in areas of high RF activity, the squelch (or mute, as it is sometimes called) may need to be adjusted to compensate for the adverse conditions in a particular location. If, with the transmitter off, the receiver’s A and/or B DIVERSITY LED INDICATORS (13) flicker or stay on, the squelch control should be turned counterclockwise until the A and/or B LEDs extinguish. When the squelch is properly adjusted, the A and/or B LEDs will only light when the system transmitter is turned on. Turning the squelch control too far counterclockwise will reduce the range, but yield a quieter squelch (mute) function. During operation, especially at ranges greater than 75 feet, one or the other of the A or B LEDs may extinguish briefly. This is normal–the unit’s DigiTRU Diversity™ reception ensures that the received audio will not be interrupted. When both LEDs extinguish, the transmitter is out of range for that given location, and the user should move closer to the receiver to re-establish the radio link.

5. Connecting the Audio Output

The UHF-3 receiver provides both a fixed mic level BALANCED MIC AUDIO OUTPUT XLR (7) and an adjustable line level AUX AUDIO OUTPUT 1/4" jack (10).

(Note: As when making any connection, make sure the amplifier or mixing board volume is at the minimum level before plugging in the receiver to avoid possible sound system damage.)

Microphone Connection

(using the UB-3 transmitter with either a headworn or lavalier microphone or the UH-3 handheld microphone transmitter) For microphone use, either the BALANCED MIC AUDIO OUTPUT XLR (7) or the 1/4" line level AUX AUDIO OUTPUT (10) can be used. The XLR output is set at a non-adjustable microphone level, similar to hardwired mic levels. Plug an XLR connector into the XLR output socket on the rear of the unit and plug the other end into your amplifier or mixing board. Make sure the phantom power on your mixing board is turned off and the volume is turned down when making connections. For your convenience, the XLR output level is preset at the factory and is not adjustable with the receiver volume control.

To use the 1/4" AUX AUDIO OUTPUT socket, follow the instructions for the Instrument Connection (above), except start the receiver volume at 1/2 MAX and adjust until the volume level is optimal. If the volume control is set too high, you may overload your mixer or amp.

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, decrease the volume to the transmitter or overload distortion may result.
