This sound regulator allows to suppress and raise separately low and high audio frequencies by 20 dB. 
It is realized with one IC TL082, which is double operational amplifier. 
Supply voltage is bipolar and can be adjusted in the range of ±9 V to ±18 V. Our recommendation is to use assembly kits with Product code, as follows: 1032 - "Uni-polar to bipolar voltage converter" or 1033 - "Power supply ±12V/100mA". 
Overall dimensions PCB 74x24mm. 

This product is a DIY assembly kit.
