Failure to do so could result in damage to the device and pos‐ sibly the user.
Installation and starting up Connecting audio and starting up Connect the audio output of the receiver to your mixer or your amplifier. Set the volume control first as follows: n If you are using a microphone input of your mixer, turn the knob to about 1 o'clock. n If you are using a line input of your mixer, turn the knob clockwise all the way to the stop. To get the best sound quality, a fine adjustment of the controller may be required.

Plug and connection assignment 6 Plug and connection assignment Introduction This chapter will help you select the right cables and plugs to connect your valuable equip‐ ment in such a way that a perfect sound experience is ensured.
Plug and connection assignment Since the interference affects both cores equally, by subtracting the phase-shifted signals, the interfering signal is completely neutralized. The result is a pure signal without any noise inter‐ ference.
Troubleshooting 7 Troubleshooting In the following we list a few common problems that may occur during operation.
Troubleshooting Symptom Remedy No sound 1. Check the power supply of transmitter and receiver. 2. Make sure that transmitter and receiver are operating in the same frequency range. The frequency can be found on the devices. 3. Test the connection between the receiver and the connected audio device (amplifier, mixer). Is the connected audio device turned on and does the signal level at the output of the receiver match the input requirements of the audio device? 4.
Troubleshooting Symptom Remedy 3. Interference can also be caused by televisions, radios or mobile phones. The sound is distorted. Toggle the sensitivity selector switch on the transmitter of change the setting of the controller [VOLUME on the receiver].
