6. ઓપરેટિંગ સૂચનાઓ
6.1. વોલ્યુમ નિયંત્રણ
- Rotate the multi-function knob on the front panel clockwise to increase volume and counter-clockwise to decrease volume.
- The volume level is displayed on the 4-inch screen.
6.2. ઇનપુટ પસંદગી
- Press the multi-function knob once to cycle through available inputs (RCA, XLR). The selected input will be shown on the display.
6.3. Gain Level Adjustment
- Long press the multi-function knob to switch between Low Gain (G-L) and High Gain (G-H) modes.
- Low Gain is suitable for sensitive IEMs, while High Gain provides more power for demanding headphones.
6.4. Quiescent Current Mode (Class-A)
Figure 4: Display showing 50mA (A-L) and 100mA (A-H) modes
- Double press the multi-function knob to switch between 50mA (A-L) and 100mA (A-H) quiescent current modes.
- The 100mA mode is a high current Class-A operation, offering a richer sound but may lead to a slower temperature rise.
- The display uses two colors to indicate the current level and temperature for easy monitoring.
6.5. પૂર્વamp/Headphone Dual Output Mode
The S17 Pro EVO allows independent selection between headphone amplifier output and preamp output. The current volume for each mode can be independently stored.

7.4. Advanced Cooling System
To maintain stable Class-A operation, which generates heat, aune's industrial designers developed a complex three-dimensional cooling structure. This system integrates a heat sink on the transistor, a heat plate at the bottom, and the chassis to form a comprehensive cooling solution. Heat is efficiently dissipated through rear plate heat emission holes, ensuring stable performance.
