带低音炮的10W的音频放大器(10W Audio Amplifier with Bass-boost)

Parts:

P1_________________22K Log.Potentiometer (Dual-gang for stereo)Technical data:

Output power: 10 Watt RMS @ 8 Ohm (1KHz sinewave)

Sensitivity: 115 to 180mV input for 10W output (depending on P2 control position)

Frequency response: See Comments above

Total harmonic distortion @ 1KHz: 0.1W 0.009% 1W 0.004% 10W 0.005%
Total harmonic distortion @ 100Hz: 0.1W 0.009% 1W 0.007% 10W 0.012%
Total harmonic distortion @10KHz: 0.1W 0.056% 1W 0.01% 10W 0.018%

Total harmonic distortion @ 100Hz and full boost: 1W 0.015% 10W 0.03%

Max. bass-boost referred to 1KHz: 400Hz = +5dB; 200Hz = +7.3dB; 100Hz = +12dB; 50Hz = +16.4dB; 30Hz = +13.3dB

Unconditionally stable on capacitive loads
