回复：偶对功放推力和控制力与功率关系问题的看法（松香味兄请看）
The rotary “volume” control determines the gain setting, which ranges from ‘0.0dB’ (no output) to ’80.0dB’ (full output). This control does not function like a typical volume: When you rotate the dial, either clockwise to raise the volume or counterclockwise to lower the volume, you are actually engaging a precision optical encoder which selects very high quality metal-film resistors that the audio signal passes through. The result is a proprietary gain circuit, called M-eVOL that doesn’t degrade the audio signal regardless of the setting, unlike all potentiometer based circuits. Since this circuitry operates in a fully balanced differential mode, no noise is introduced to the audio signal. Futhermore, since there are no actual moving parts,this technology has a minimum life expectancy of one million rotations.
The MOON i-7 integrated amplifier provides a range of one-hundred and thirty (130) unique volume settings. This is
achieved as follows: Within the 0.0dB to 30.0dB range, you can increase and decrease the volume in 1.0dB steps. From the 30.0dB to 80.0dB range, you can increase and decrease the volume by either 0.5dB or 1.0dB steps; By rotating the volume control slowly, the level will change by 0.5dB increments. A quicker rotation will change the volume in 1.0dB increments.
