line level prilagodba

[Johnny]

ima jedno gitarsko pojačalce koje ima link na iphone jack.

Ja bi to želio koristiti kao efekt send / return odnosno kao pre out / main in na klasičnom setupu preamp i izlaz.
Jack od iphone-a je zapravo mic in i headphone out pa me zanima koji su tu naponi i impedancije da složim neki adapter

“i-CUBE LINK” is a function that allows the MICRO CUBE GX
to be used simultaneously for conventional AUX IN and
as an audio interface for your iPad/iPhone when the iPad/
iPhone is connected via the included mini cable (4-pole).
This function lets you use an iPad/iPhone app to record
and play back the sound of your guitar.

output
The sound of your guitar will be sent from
the MICRO CUBE GX to the iPad/iPhone.
* If you want to hear only the sound that’s being input from
the iPad/iPhone, turn down the [VOLUME] knob.
For details on i-CUBE LINK and on iPhone/iPad apps that
can use i-CUBE LINK, refer to Roland website.

EDIT:

Sorry što je pitanje bezvezno i nejasno. Malo sam googlao. Pedala koju bi ja stavio u loop umjesto iphone-a ima izlaznu impedanciju 1k, a iphone 1 ohm.

Probat ću dal radi, ako ne radi ok ću ubacit bafera.
