high GAIN stereo bass TREBLE with input selector

---

This Bass Treble and Gain circuit was designed by Respected Peter J Baxandall , 

You will find many versions of it on Google and able to make most of them on this PCB. 

The Gain circuit on this board can drive any type of Amplifier.

Separate IC's are used for each channel so excellent channel separation and  minimum cross talk.

Input selector switch for using 2 stereo inputs simultaneously such as LCD / CD / Aux among others.

• Bass Treble Boost / Cut -   17 dB symmetrical curve Boost / Cut. 1khz cutoff  frequency. 
• High signal GAIN -  up to 26 dB signal gain.
• Universal amplifier usability - can be used with any amplifier made of IC or Transistors.
• Standard Components -  All components used are available online or at your local electronics store.  
• No SMD components - Only through hole components used, making soldering and replacement hassle free.  
• Cost effective - This amplifier can be made in a fraction of cost compared to similar amplifiers available in market.
