1044 - 5-Band Graphic Equaliser

Graphic equalisers are a must in any good hi-fi systems! They enable you to shape the response of the system to the particular room, or in recordings to improve deficiencies of the equipment or the original recording. A good equalizer, used with skill can dramatically improve the quality of your listening pleasure.

This equalizer has five bands which cover all the audible frequencies, centred at 60, 250, 1,000, 4,000 and 16,000 Hz. The spacing between peak frequencies is two octaves which is quite adequate for most domestic applications. Frequency adjustment is 12dB/octave.

The circuit is for one channel and if you want to use it for STEREO you should build two, one for each channel of your system.
