Guitar Impedance ?
Mega ohm / Mohm = 1
Kilo ohm /Kohm = 1000
Ohm / = 1000000
Whirlwind EDB1 Direct Box
Input Impedance: 20 Kohms or 20,000 ohms or (0.02 MOhms ? // I think).
Output Impedance: 150 ohms
PreSonus AudioBox USB: Instrument Input
TS Female Unbalanced Input Impedance 0.5 Mohm or 500,000 ohm Microphone Preamp
Type XLR Female Balanced
Input Impedance (Balanced) 1200 ohm or 1.2 Kohm
Frequency Response (±3.0 dB) 14 Hz to 70 kHz
if the PreSonus has a combo jack input, the jack on those is unbalanced.
try either, putting your guitar straight in there
using a balanced microphone cable from the Whirlwind to the balanced in on the PreSonus.
you should find out the ohm rating on your guitars output, in whatever active or passive modes it can produce.
typically you need to be within 10 X the ohm rating for source and destination connections.
Read this. Prepare to DI!
one reason the Nobels pedals are handy is because they have a 1 Mohm in to a 2 Kohms out and,
I think it's constantly buffered to that, so it acts like an impedance changer as well as a pedal.
so their pre amp or AB switchers are handy for pre loading your guitar. I prefer the way the ODR-1 loads guitars though, to the others. so that's always my 1st connection. then I can generally forget subsequent nonsense.
