Hi ,please help.I bought cassette deck Pioneer ct-f1250 ,it's my first deck .And I think something wrong.When I do recording, the level of sound cutting half and treble little lower.So when I operate switch ''source and tape'' Heard a big difference.Also I don't know how use tape calibrator and how to do calibration.and how much does this affect for recording.And my question again about different sound level ,I think it should the same i mean source and tape sound.Please someone explain to me.
Thanks
