10 w bass booster amplifier circuit
Interesting Facts:
Can be directly connected to CD players, tuners and tape recorders.
Schematic shows left channel only, but C3, C4, IC1 and nutrition are common to both channels.
Figures in parentheses indicate the right channel pin IC1.
Log type P2 ensures a more powerful bass even regulators.
Do not exceed 18 + 18V supply.
T3 and T4 must be paid for the hedgehog.
D1 must be in thermal contact with the Q1.
Quiescent current (best measured with an avocado, meter in series with Q3 Emitter) is not critical.
Adjust the volume, and a minimum of resistance R3.
Power on the track and adjust R3 to read a current drawing of about 20 to 25mA.
Wait about 15 minutes to see if the current is variable and the necessary adjustments.
Proper grounding is extremely important to eliminate hum and ground. Connect the same point of land on either side of J1, P1, C2, C3 and C4. Connect C9 leave the country.
Then connect separately the input patterns and output mass of food.
Specifications:
Power: 10 W RMS @ 8 Ohm (1 KHz sine wave)
Sensitivity: 115 to 180mV input for 10W output (depending on the position control P2)
Frequency Response: see above comments
Harmonic Distortion @ 1kHz: 0.1W 0.009% 1W 0.004% 10W 0.005%
THD @ 100 Hz: 0.1 W 1 W 10W 0.009% 0.007% 0.012%
THD @ 10KHz: 0.1W 0.056% 0.018% 0.01% 1 W 10W
THD @ 100 Hz and full boost: 1W 0.015% 10W 0.03%
Max. Bass boost referred to 1 kHz: 400 Hz = 5 dB 200 Hz = 7.3 dB = 12 dB 100 Hz, 50 Hz = 16.4 dB = 13.3 dB 30Hz
Unconditionally stable capacitance
