Preamplifier module with volume / bass control NE5532 DIP8

This preamplifier module with volume and bass control (frequency range 50Hz-150Hz) has two DIP 8 supports to change the AOP (operational amplifier) ​​as it sees fit. It requires only a small transformer from 15 VA 230 V AC to 12 V on a secondary to operate.

It will allow to use any stereo signal in input and to leave it in mono to attack a monophonic amplifier and therefore a single speaker. It is recommended for DIY design of subwoofer for example.

You can change the OP NE 5532 amps byOP2134to get a warmer, analog sound.
