    • External stereo input (line level in - modular level out)
    • Non traditional noise source
    • Usb port... to plug a lamp, fan or whatever you need.


The output is modular level.

Available assembled and DIY


Bill Of Materials:
  • 1 x Resistors Zero Ohm (jumper) - SMD 0603 (populate 5v if you have 5v rail, if not 12v)
  • 2 x Resistors 100k - SMD 0603 (R1,R4)
  • 2 x Resistors 33k - SMD 0603 (R2,R5)
  • 2 x Resistors 100 Ohm - SMD 0603 (R3,R6)
  • 2 x Capacitors 100nF - SMD 0603 (C1, C2)
  • 1 x TL072 - SMD soic-8
  • 2 x mini jack
  • 1 x Male headers - 2x8 2,54 mm

  • +12v
  • -12v
  • +5v

All components goes in the back of the panel, which is the pcb also

Low Coast has not voltage regulator, if you don't have +5v in your modular be sure to get a "12v tolerant" unit

Jacks need to be wired like this
