Adjustable Bass Filter Circuit

Of a power amp bass amp filter circuit can be used in different times, in addition + – 60 + symmetrical voltage – 15 volts regulator circuit for limiting transistor has

The frequency of the filter cut-off regulated na is a stereo potentiometer P1. For acoustic applications, the filter does not it must be perfect and therefore it was possible use of a stereo potentiometer.

which unfortunately does not have a good one concurrency of both sections. A little bit corrects the fact that it is a potentiometer of which, by definition, always has a better one concurrency rather than a logarithm potentiometer.

In the falling part of the slope characteristics is 12 dB / oct. complement changeable filter is not a low-pass strobe filter implemented on the US2A operational amplifier. The frequency of cutting off this filter is about 150 Hz. The accidental characteristics both filters for different positions of the slider the potentiometer.

Regulation is subjective choosing the filter’s limiting frequency and the level of the signal reproduced by subwoofer. In principle, there is no general tips on how to follow the rules lacjach. The only thing that can be dealt with is regulation at average headroom Play music for different music recordings. It’s best to choose which recordings are well known (auscultated) then it will be easier to pick up the differences nice sound.
