Dear Dr. Sound, 

With a TOA A-2120 amplifier, what is the better way to plug a iPhone or a Laptop?

And, if a want to use the MIC port, what is the correct pinout?



Dear Sebastien,

Thank you for contacting TOA.

Typically you connect your line level source into the AUX 1 or AUX 2 inputs.

As for the mic input, PIN 1 is your ground (shield), PIN 2 is hot, and PIN 3 is cold.

If you have further questions please let me know.
Your Dr. Sound
