- Postavite na PHONE for turntables.
- Postavite na RCA for line-level devices.
3. Kontrola jačine zvuka
Adjust the Volume Knob on the front panel to achieve your desired listening level. Start with a low volume and gradually increase it.
4. Tone Control and Bypass
The P7 features Bass and Treble controls for sound customization. Use the Tone/Bypass Switch to engage or disengage these controls:
