Hi all,


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.

The 5-pin DIN should be used for audio line in/out.  It sounds like you are getting output but very faint.  Is there a headphone connection (3.5) you can plug into?


The link below should provide some explanation.

No, got no 3,5 mm input.

This is how it looks like, is the mic ext a possible input instead?

Function to tape position.

Insert blank cassette and push REC + PLAY buttons.

You must here sound from input device now.


If sound is low, you must open boombox and add custom line in jack.

You need service manual and you must understand of electronics,
