I bought my self a Sharp GF-7300 on eBay.
I have a mic and an amp DINdin connection on the Sharp GF-7300.
Yesterday I tried the amp DIN connection, but the signal was very low.
The signal came from my headphone amp's aux out into a DIN connection, into the Sharp GF-7300.
I could not use the volume and had to crank my headphone amp to max, and I guess that is a bad thing.
Is the signal from a headphone amp lower than if you take it from a phone 3,5 mm plug?
Is there other solutions to use my Sharp GF-7300 input?
I want to use it for audio-in.
