Cartridge Settings (Gain, Impedance, Capacitance)
The Tube Box S2 offers adjustable settings to optimize performance for various MM and MC cartridges. These settings are crucial for achieving the best sound quality.
- Osiągać: Use the front panel selector to choose the appropriate gain setting for your cartridge. MM cartridges typically require lower gain (e.g., 40dB), while MC cartridges require higher gain (e.g., 60dB). Consult your cartridge's specifications for the recommended gain.
- Impedance & Capacitance: These are adjusted via DIP switches located on the underside of the unit. Refer to your cartridge's specifications for the recommended load impedance and capacitance. For high-output MC cartridges, the fixed 47kOhm setting is often suitable.
6. Instrukcja obsługi
- Włączanie: Once all connections are secure, plug the power adapter into the wall outlet. The unit will power on automatically.
- Select Input on AmpLiyfikator: Choose the corresponding line-level input on your amplifier where the Tube Box S2 is connected.
- Odtwórz rekord: Start playing a record on your turntable.
- Dostosuj głośność: Control the overall volume using your ampliyfikator.
- Filtr poddźwiękowy: If you experience excessive low-frequency rumble or woofer pumping, activate the subsonic filter using the front panel switch. This helps to remove infrasonic frequencies that can cause distortion.
7. Konserwacja
Czyszczenie
To clean the unit, use a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the finish.
Wymiana rurki
The ECC83 tubes in the Tube Box S2 are designed to be interchangeable, allowing for sound customization.
