10 Watt Audio Amplifier Bass Booster

As this series amplifier also uses a number of frequencies to the loudspeaker, the bass frequencies will be reduced. Therefore, the need to install bass-boost control on the feedback loop amplifier, this is done to overcome the declining quality. Graphic bass can reach a maximum at +16.4 dB @ 50Hz.

Note: this can be connected Rangkaian directly on the CD player, tuner, and tape recorder. Q3 and Q4 must be in pairs with the heatsinks.

Set the volume control on the position of the minimum and R3 with a minimum value resistansion also. try to activate a series of da set R3 legible to flow about 20 to 25mA. Wait for 15 minutes, connect the ground at J1, P1, C2, C3dan C4. Connect the output on the ground C9.
