Guifeng ZENA preamp + Antileon EVO postamp has noise, and there is no noise when the sound source signal line is dialed off, what is the reason?
In the audio system composed of the Guifeng Zena preamp and the Antileon EVO amplifier, there was a noise problem, but the noise disappeared after the sound source signal line was dialed. This usually indicates that the noise is caused by the source signal line or signal source, rather than a problem with the preamp or postamp device itself. Here are some possible causes and workarounds:
1. Quality problems with the signal line of the audio source: Similarly, the use of poor quality or aging audio cables may cause noise. It is advisable to replace it with a high-quality audio cable and make sure it works for your sound system.
2. Poor contact of the signal cable: Poor connection or poor contact of the audio cable may also cause noise, try to plug it in and unplug to ensure good contact.
3Electromagnetic interference: Electromagnetic interference (EMI) can also introduce noise through audio signal lines. Try to keep the signal line away from potential sources of interference, such as power lines, computers, or other electronic devices.
4. Problems with audio source equipment: There may be problems with audio source equipment (such as CD** device, digital audio ** device, etc.), resulting in noise. Please check that the source device is working properly and try to test it with a different source device.
5 Device Compatibility Issues: Although both Guifeng Zena and Antileon EVO are high-quality audio equipment, in some cases, there may be compatibility issues between devices of different brands or models. Please make sure that the connection and settings between the pre-amp and post-amp devices are correct, and refer to the respective instructions for configuration.
6 Power supply problems: Power interference can also cause noise. Make sure your sound system's power is stable** and try to use a separate power outlet or filter to reduce potential power interference.
If the noise problem cannot be solved after the above inspection and treatment, it is recommended that you contact Yuesheng audio professional maintenance personnel or Guifeng technical support for more professional help and solutions. They can perform a detailed inspection of your sound system to identify and resolve issues.
