Plug and connection assignment

Introduction

• This chapter will help you select the right cables and plugs to connect your valuable equipment in such a way that a perfect sound experience is ensured.
• Please note these advices, because especially in ‘Sound & Light’ caution is indicated: Even if a plug fits into the socket, an incorrect connection may result in a destroyed power amp, a short circuit or ‘just’ in poor transmission quality!

Balanced and unbalanced transmission

• Unbalanced transmission is mainly used in semi-professional environment and in hifi use.
• Instrument cables with two conductors (one core plus shielding) are typical representatives of the unbalanced transmission. One conductor is ground and shielding while the signal is transmitted through the core.
• Unbalanced transmission is susceptible to electromagnetic interference, especially at low levels, such as microphone signals and when using long cables.
• In a professional environment, therefore, the balanced transmission is preferred, because this enables an undisturbed transmission of signals over long distances. In addition to the conductors Ground’ and ‘Signal’, in a balanced transmission a second core is added. This also transfers the signal, but phase-shifted by 180°.
• 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 interference.

Troubleshooting

In the following we list a few common problems that may occur during operation. We give you some suggestions for easy troubleshooting:

2. Make sure that transmitter and receiver are operating in the same frequency range. The frequency range can be found on the devices.
3. Are transmitter and receiver set to the same channel?
4. 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?
5. See if the audio transmission works when you move the transmitter closer to the receiver.
6. Make sure that no metal objects near the transmitter or receiver obstruct the transmission.
Transmission is interrupted| 1. Modify the orientation of the antennas.
Symptom| Remedy
---|---
| 2. If you use more than one wireless system at the same time, check the used frequencies and channels.
3. Interference can also be caused by other radio or in-ear systems.

If the procedures recommended above do not succeed, please contact our Service Center. You can find the contact information at www.thomann.de.
