Occasional flickering of the peak LED on loud input signals to the transmitter is normal. However, If the peak LED lights continuously, the volume into the transmitter should be decreased or audio distortion may result. 4 13 LINK 4TM PLUG-IN TRANSMITTER Receiver Volume Controls Adjust The volume controls work only for the 1/4" sum output. Turn Volume controls on the UHF-24 receiver clockwise to near full gain. Adjust Volume up or down so that no audio distortion is present when amplifier or mixer is set at their usual levels. At full gain, the system gain is approximately +20dB higher than a direct line-to-amp connection. If the fixed level XLR OUTPUTS (11) are used, the volume level of each receiver should be adjusted by the mixer to which the UHF-24 receiver is connected. UHF-24 RECEIVER Connecting Audio Outputs The UHF-24 receiver provides both a fixed mic level balanced audio output XLR for each channel and an adjustable line level A+B unbalanced audio output 1/4" jack which sums the CH-A plus CH-B audio signals. · The balanced XLR OUTPUTS (11) are preset at the factory and are not adjustable with the receiver volume controls. For each channel you wish to use, insert an audio cord with a (female) XLR plug into its audio jack on the back of the receiver. Plug the other end of this cord into your amplifier, effects or mixing board. Factory setting is MED for hardwire dynamic microphone. This is a setting to be used in most typical close microphone applications. Set for maximum possible gain and headroom without noticeable distortion of the high level peaks. Experiment and set for maximum possible gain without audible distortion on the high level peaks. (Note: Selecting LOW gain setting can compromise the signal-to-noise and it is not recommended. ) The microphone is now ready to use. A or B LED indicator on corresponding receiver should now be on, indicating a received signal from the transmitter. When ready to speak, slide the OFF/STANDBY/ON SWITCH (36) to the ON position and hardwire mute switch if it was off. Adjust the volume of the receiver as per in the receiver operating instruction. Notes: · The microphone ball on your hardwire microphone functions as an integral antenna. For proper operation, it should not be cover or touch during operation. volume, transmitter location and speaker placement so that acoustic feedback (howling or screeching) will be avoided. 39 34 33 32 31 Tone SquelchTM and Additional Operating Notes The UHF-24 receiver and transmitters feature Nady's Tone SquelchTM circuit. [. . . ] The LOW BAT LED (29) will give a single flash, indicating usable battery strength. In case of dead or low battery, the LOW BAT LED will either not go on at all or will stay on continuously. During use, if the LOW BAT LED stays on continuously, it is indicating that the battery should be replaced with a fresh one. To preserve battery life, turn the transmitter off when not in use. 17 20 Receiver Volume Controls Adjust The volume controls adjust only the 1/4" sum output. [. . . ]
