Nady U-41 Manual - Page 5

U-41 QUAD RECEIVER The U-41 QUAD also has a summed adjustable line level unbalanced output for all channels (MIX). To use, just plug an audio cable with a 1⁄4" mono plug into the MIX out and plug the other end to your amplifier or mixing board. Turn volume controls (5) on the U-41 QUAD UHF receiver clockwise to near full gain. Adjust each channel's volume up or down so that no audio distortion is present when the amplifier or mixer is set at their usual levels. Your U-41QUAD is now operational and ready to use. Now that you have completed the above step, proceed to instructions for the UH-4or UB-4 transmitter included with your system. Additional Features - Tone Squelch™ The U-41 QUAD receiver and transmitters feature Nady's Tone Squelch™ circuit. Nady offers Tone Squelch™ for professional uses and anyone who needs advanced protection against RF interference during a recording, performance, or presentation. This feature is strongly recommended for situations where the transmitter is turned on or off during use. With Tone Squelch™, an unwanted signal on the same operating which may enter your inactive receiver will not be amplified by your connected equipment even if the receiver is left on with the transmitter(s) off. Thus Tone Squelch™ prevents a pop or disruptive noise from your sound system. The receiver detects a specific tone code signal from your transmitter, which unlocks your receiver's audio. In this manner only your own modulated signal can then be heard. (The receiver has an internal Tone Squelch™ defeat feature. Contact your Nady dealer or Nady Systems Customer Service for details.) Note: • The noise from the unused channels are normal and do not indicate a defective channel. This noise is caused by the mixing of the RF waves. • To prevent possible undesired noise from the unused channel during use, keep the volume controls of unused channels, (corresponding transmitter off) turned to minimum counter clockwise or turned off in the amplifier or the mixer. The audio should only be "live" if the transmitter is on. • 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. • For a GT system, use the AF OUT outputs connect directly to your own system. The system output is approximately +4dB higher than a direct cord-to-amp connection. • Only one transmitter can be used with one receiver. It is not possible to use two transmitters on the same frequency and mix the output of these transmitters into one wireless receiver. The U-41 QUAD receiver has 4 discrete receivers built in so can be used with 4 transmitters on the same frequencies as these 4 receivers. 5
