[. . . ] 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. The volume level of each receiver should be adjusted by the mixing board. · The A+B UNBALANCED SUM (13) audio output is controlled by the rear panel volume control for each channel. To use the A+B unbalanced sum audio output, just plug an audio cable with a 1/4" mono plug (TS) into the 1/4" jack and plug the other end to your amplifier or mixing board. Turn the volume controls on the UHF-24 receiver clockwise to near full gain. Adjust each volume up or down so that no audio distortion is present when the ampflier or mixer is set at their usual levels. The adjustable level unbalanced sum output is for line level connections. Microphone Connection (Using the UH-4, UB-4 and the LINK-4 transmitters) For microphone use, either the XLR balanced mic audio output or the 1/4" line level A+B unbalanced output can be used. The XLR balanced output is non-adjustable microphone level, similar to hardwire mic levels. Plug an XLR connector into one or both of the XLR output jacks on the rear of the unit and plug the other end(s) into your amplifier or mixing board. (Note: 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 levels are preset at the factory and are not adjustable with the receiver volume controls. To use the A+B unbalanced output 1/4" jack, follow the instructions for the Instrument Connection (below), except start with the receiver volume at 1/2 maximum and adjust the volume control for each channel until the mixed CH A or CH B volume levels are optimal. If the volume controls are set too high, you may overload your mixer or amplifier. Instrument Connection (Using the UB-4 instrument transmitter) Insert an audio cord with a 1/4" mono phone plug in the A+B unbalanced output jack on the rear panel of the receiver. Plug the other end of the cord into an amplifier, effect, or mixing board. Adjust the appropriate volume control for the channel being used on the UHF-24 receiver clockwise to about 3/4 rotation, until the mixed volume level is comfortable for your application. This setting is roughly equivalent to a direct instrument cord connection. (Note: Since this is a mixed output of both channels CH-A and CH-B, both channels will be processed simultaneously by the amplifier and/or effects connected to, which may not be appropriate for your application. ) Your UHF-24 receiver is now operational and ready to use. Now that you have completed the above step, proceed to instructions for the actual transmitter, UH-4, UB-4 or LINK 4, that is included with your system. Level Trim Adjust For optimum performance, an INPUT SELECT SWITCH (38) is provided. [. . . ] 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. Turn VOLUME CONTROLS (10) on the UHF24 receiver clockwise to near full gain. [. . . ]
