3.3 വോളിയം നിയന്ത്രണം
Adjust the audio output level using the large rotary volume knob on the front panel. Rotate clockwise to increase volume and counter-clockwise to decrease volume.
3.4 ഗെയിൻ സെറ്റിംഗ്
The 'GAIN' switch on the rear panel allows you to optimize the output level for different headphone impedances:
- NORM (Normal): Standard gain setting for most headphones.
- ഉയർന്നത്: Provides an additional +12dB gain for high-impedance headphones or when more output power is required.
3.5 Output Mode (Fixed/Variable)
The 'OUTPUT' switch on the rear panel determines the output behavior:
- VAR (Variable): Headphone output volume is controlled by the volume knob. This is the standard mode for headphone listening.
- സ്ഥിരമായത്: Provides a fixed line-level output (700 mV) suitable for connecting to an external amplifier or active speakers. In this mode, the volume knob does not control the output level.
3.6 Charge Function (On/Off)
The 'CHARGE' switch on the rear panel controls whether the connected device (e.g., iPod/iPhone) is charged by the DA-10-SP when connected via USB-A.
- ഓൺ: The connected device will charge.
- ഓഫാണ്: The connected device will not charge. This can be useful to extend the DA-10-SP's battery life or to reduce potential electrical noise when charging is not required.
