4.3 Adjusting Audio
- د حجم کنټرول: Rotate the VOLUME knob to increase or decrease the overall sound level.
- د ټریبل کنټرول: Rotate the TREBLE knob to adjust the high-frequency response. Turn clockwise for more treble, counter-clockwise for less.
- د باس کنټرول: Rotate the BASS knob to adjust the low-frequency response. Turn clockwise for more bass, counter-clockwise for less.
4.4 Power Output Considerations
Optimal audio output requires a suitable power supply and speaker impedance. The table below illustrates the approximate output power based on input voltage او د سپیکر خنډ.
شکل 6: Power Output Comparison Table. This table details the R&L channel output power at 1KHz for various input voltages (12V, 15V, 19V, 24V) and speaker impedances (4Ω, 8Ω).
Important Note: There must be enough voltage and current input to achieve the rated power output. Higher voltage and current generally result in higher power. For the same conditions, a smaller speaker impedance will yield greater power.
