3. Proizvod je gotovview
The Topping A50 III is a high-performance headphone amplifier designed for desktop audio setups. It features advanced NFCA (Nested Feedback Composite Amplifier) modules, offering exceptional audio fidelity and powerful output capabilities for a wide range of headphones.
4. Ključne karakteristike
- Ultra-high Performance NFCA Modules: Utilizes NFCA (Nested Feedback Composite Amplifier) modules with Voltage Current hybrid feedback architecture and UHGF (UltraHigh Gain Feedback) technology for excellent DC and AC performance.
- High-Output Current Drive: Capable of driving low-impedance headphones with ease.
- Full Aluminum Case: Unique integrated design from solid aluminum bricks, providing excellent electromagnetic shielding, smooth appearance, and superior strength.
- Svestrana primjena: Features 6.35mm single-ended and 4.4mm balanced headphone jacks, as well as RCA single-ended and TRS balanced inputs for various combinations.
- Wide Headphone Adaptation: Three gain selections (Low, Medium, High) to suit all types of headphones, including sensitive IEMs with a low noise floor of 0.3uVrms.
- Snažan izlaz: Delivers up to 3500mW x 2, ensuring most headphones maximize their performance with a low distortion rate (<0.1%) even at high power.
- 12V Trigger Function: Can be switched on and off with a compatible device (e.g., Topping D50 III) via a 12V Trigger connection.
5. Podešavanje
5.1 Povezivanje napajanja
- Ensure the A50 III is powered off.
- Connect the provided power adapter to the DC 15V input on the rear panel of the A50 III.
- Uključite adapter za napajanje u odgovarajuću zidnu utičnicu.
5.2 Povezivanje audio izvora
The A50 III supports both single-ended (RCA) and balanced (TRS) audio inputs.
- RCA ulaz: Connect your audio source (e.g., DAC, CD player) to the RCA L/R input jacks on the rear panel using RCA cables.
- TRS Balanced Input: Connect your audio source to the TRS L/R input jacks on the rear panel using 6.35mm TRS cables.
5.3 Povezivanje slušalica
The A50 III offers two headphone output options on the front panel:
- 6.35mm Single-Ended: Plug your headphones into the 6.35mm (1/4 inch) headphone jack.
- 4.4mm Balanced: For balanced headphones, use the 4.4mm balanced headphone jack.
5.4 Priključak okidača 12V (opciono)
If you have a compatible device with a 12V Trigger output (e.g., Topping D50 III), you can connect it to the 12V Trigger input on the A50 III's rear panel. This allows the A50 III to power on/off synchronously with the connected device.
6. Operacija
6.1 Uključivanje/isključivanje napajanja
Press the power button on the front panel to turn the A50 III on or off. The LED indicator will illuminate when the device is powered on.
6.2 Kontrola jačine zvuka
Rotate the large knob on the front panel clockwise to increase volume and counter-clockwise to decrease volume. Start with a low volume setting before playing audio.
6.3 Gain Selection
The A50 III features three gain settings (L: Low, M: Medium, H: High) to match the sensitivity of your headphones. Use the gain switch on the front panel to select the appropriate setting. Higher gain provides more power for demanding headphones, while lower gain is suitable for sensitive IEMs to avoid noise and excessive volume.
6.4 Odabir ulaza
The A50 III automatically detects the active input. If multiple inputs are connected, ensure only one source is playing at a time or switch between them using your source device.
7. Povezivanje
