When users in the audio recording, the speaker unit and other equipment place is not necessarily perfect, pure pass-through preamp may not be able to meet the requirements, then add the tone adjustment becomes very important, if you have no extra power supply equipment, Passive preamp tone is preferred. It can adjust the treble and bass frequency effect is very obvious, let amplifier and speakers with more reasonably.

The board uses high-precision 5 ring resistors and metalized capacitors, sealed potentiometers, so to maximize results.

Notice:

LM1036 equal loudness function Will have reflect when in a small volume of time, the effect is not very obvious, it need your amplifier and speakers have sufficient resolution, so do not suspect a problem with the circuit design. Discriminating switch whether have effective, it is have a simple way, it is put the treble and the bass knob turn to the minimum, and put the volume turn into about 1/10 position, then open and close the equal Loudness switch, then you could listen to come out the difference.
