[. . . ] UHF-24 Dual Channel Receiver UHF Wireless Microphone System SERVICE INFORMATION (U. S. ) If you are experiencing operation problem with your system, check out the support page on the Nady website: www. nady. com for help and for contacting the Nady Service Department. Should your wireless System require service, you must contact the Nady Service Department at (510) 652-2411 for a Return Authorization (R/A) Number and a service quote (if out of warranty). Make sure the R/A Number is clearly marked on the outside of the package. Cashier's check or money is enclosed (If not prepaid with credit card), and ship the unit prepaid to: Nady System Inc. , Service Department, 6701 Shellmound Street, Emeryville, CA 94608. [. . . ] The volume level of each receiver should be adjusted by the mixing board. The fixed level balanced XLR outputs are for mic level connections. · 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. Tuning the volume up to maximum will provide 4dB gain over a cord. (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. You could select the switch to LO, MED or HI gain setting defending to your microphone use. Depending on the average distance between vocalist's mouth and microphone, you can adjust the level for your application. [. . . ] Turn VOLUME CONTROLS (10) on the UHF24 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 (+4dB for GT) 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 UHF24 receiver is connected. 16 Level Trim Adjust For optimum performance, an INPUT LEVEL CONTROL (30) for LT/HM is provided.
