Produktua amaituview
The Topping L50 is designed to deliver exceptional audio performance for headphones. Key features include:
- NFCA Circuit: Utilizes a redesigned NFCA (Nested Feedback Composite Amplifier) circuit for ultra-low noise and distortion.
- Potentzia handiko irteera: Provides significant power output to drive a wide range of headphones, including high-impedance models.
- Three Gain Settings: Adjustable gain to perfectly match various headphone sensitivities, from sensitive IEMs to demanding over-ear headphones.
- Saihestu irteera: Features a pass-through function that allows the input signal to be directly outputted to RCA or TRS when the unit is powered off, useful for connecting to active speakers or monitor speakers with a DAC's pre-amp funtzioa.

Konfigurazioa
- Lekua: Place the L50 on a stable, flat surface, ensuring adequate ventilation.
- Konektatu audio iturria: Connect your audio source (e.g., DAC, pre-amplifier) to the L50's input jacks. The L50 supports both RCA and TRS inputs.
- For RCA input, use high-quality RCA cables to connect the left and right channels from your source to the L50's RCA input ports.
- For TRS input, use balanced TRS cables to connect the left and right channels from your source to the L50's TRS input ports.
- Konektatu entzungailuak: Plug your headphones into the appropriate output jack on the front panel (6.35mm or 4-pin XLR).
- Konektatu energia: Connect the provided power adapter to the 15VAC power input on the rear panel, then plug the adapter into a wall outlet.
- Optional: Connect Pass-through Output: If you wish to use the pass-through function, connect the L50's RCA or TRS pass-through outputs to active speakers or another amplifier. This output is active when the L50 is powered off, allowing the input signal to bypass the ampbiziagoa.

Funtzionamendu-argibideak
- Piztu/Itzali: The L50 typically powers on when connected to the power supply. Some models may have a power switch. Refer to the front panel for specific controls.
- Bolumen kontrola: Rotate the volume knob on the front panel to adjust the listening level. Start with a low volume and gradually increase it to a comfortable level.
- Irabaziaren ezarpena: The L50 features three gain options (Low, Medium, High) to optimize performance for different headphones.
Image: Diagram showing the three gain options (H, M, L) on the Topping L50. This feature allows matching the amplifier's output to the sensitivity of various headphones, from low-sensitivity over-ears to high-sensitivity IEMs, ensuring minimal background noise.
- Erabili Baxua (L) gain for highly sensitive headphones or IEMs to prevent excessive volume and background noise.
- Erabili Ertaina (M) gain for most standard headphones.
- Erabili Altua (H) gain for demanding, low-sensitivity, or high-impedance headphones that require more power.
- Sarrera hautatzea: If your L50 has multiple input options (e.g., RCA, TRS), ensure the correct input is selected via the input selector switch, if present.
Mantentzea
- Garbiketa: Gently wipe the exterior of the amplifier with a soft, dry, lint-free cloth. Do not use abrasive cleaners, solvents, or chemical sprays.
- Hautsa: Keep the device free from dust accumulation. Use a soft brush or compressed air to clean vents if necessary.
- Biltegiratzea: Gailua denbora luzez gordetzen baduzu, deskonektatu korrontetik eta gorde leku fresko eta lehor batean.
