Installation Notes on wireless transmission n This device utilizes frequencies that are not harmonized within the European Union (EU) and therefore may only be used in certain EU member states. In all European countries, the frequencies used for the transmission of audio signals are strictly regulated. Before you start, make sure the frequencies are allowed in the respective country and check whether the operation must be reported to the appropriate authority.
Installation Connecting audio and starting up Connect the audio inputs of the transmitter with suitable line outputs of your mixer or your amplifier. Set the controls for the volume (6) first to a middle position. To get the best sound quality, a fine adjustment of the controller may be required. If the input level is too hight, switch the noise dampening function on.

Plug and connection assignment 8 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 9 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. Ensure that the transmitter and receiver are operating in the same frequency range and that the transmitter antenna is designed for this frequency range. The frequency range can be found on the devices. 3. Are the transmitter and receiver set to the same frequency group and channel? 4. Test the connection between the transmitter and the connected audio device (amplifier, mixer).
Troubleshooting Symptom Remedy 2. If you use more than one wireless system at the same time, check the used frequency groups and channels. 3. Interference can also be caused by televisions, radios or mobile phones. The sound is distorted. Change the [VOLUME] control settings on the transmitter. If the procedures recommended above do not succeed, please contact our Service Center. You can find the contact information at www.thomann.de.
