This is a custom Stereo Preamp capable of handling Instrument Level signals as well as Line Level signals. It's also capable of taking an instrument level signal and boost it up to line level, and even further.
The input/output knobs act as 'attenuators'. The boost knob goes from 0dB (min) up to +30dB (max).
Specifications in brief:
▹ Input impedance: 500kΩ
▹ Output impedance: 100Ω
▹ Boost up to +30dB
▹ Standard TRS jacks (6.35mm, 1/4")
▹ Supply required: 9V DC (negative tip)
▹ Current draw: 110mA
▹ Internal voltage doubler circuit. It make use of the classic 9V supply to produce a dual rail supply ±15V that provides you more than enough headroom. (~24Vpp)
