  • High-quality cables with good shielding performance are essential to prevent unwanted noise and maintain audio clarity.

  • No, this is a pure passive preamp with no gain. It only controls volume and does not amplify the audio signal.

  • At maximum volume, the signal passes through directly without any attenuation, ensuring original audio fidelity.

  • Passive preamps avoid sound coloration and distortion since they use no powered transistors, ideal when your source devices already have high output.

  • Yes, it's perfect for active speakers and dedicated amplifiers that already provide sufficient gain, ensuring a clear, uncolored audio signal.
