When users in the audio recording,the speaker unit and other equipment place is not necessarily perfect, pure passthrough 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.
