- Sortida potent: 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. Configuració
5.1 Connexió de potència
- 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.
- Connecteu l'adaptador de corrent a una presa de corrent adequada.
5.2 Connexió de fonts d'àudio
The A50 III supports both single-ended (RCA) and balanced (TRS) audio inputs.
- Entrada RCA: 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 Connectar auriculars
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 12V Trigger Connection (Optional)
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. Funcionament
6.1 Encès/Apagat
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.
