- The circuit that designed is a passive one but you can make it an active one by adding a pre amp at the output.
- The first stage acts as a main tone stage. It balances the bass and the treble. The 0.01 cap is for high frequency while the 0.22uF cap is for low frequency.
- The second stage is for sound compression.
- he caps works the same as at the first stage only that they are there to start the sound compression that is received from the input stage.
- The 2.2k resistor delays the sound thereby multiplying the compression.
- The 10k variable resistor is there used to tune the compression depending on the frequency of the speaker. If you are using 4 to 6 inches hi-fi speakers, I advise you to keep the 10k variable resistor at 0 ohm.
- The circuit is not copyrighted and you can change it to suit your requirement. All I ask is to be posting the updates of the circuit design on the site.
NOTES:
- Assemble the circuit on a good quality PCB.
- This circuit does not require a power supply.
- POT R6 is for volume control.
- Switch S1 can be a slide switch and it is the DX Bass switch.
