5. Connecting the Audio Output
The UHF-4 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-4 transmitter with either a headworn or lavalier microphone or the UH-4 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-4 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.
