hi.
I am using an iphone 4 with djay 2. i use the ‘split output’ option (without an adapter - just normal headphones plugged in) so i can cue up songs in one ear, and listen to whats actually playing in the other ear.
when i record a mix with split output ON, the sound quality drops slightly. in particular the highs diminish. if i switch the split output OFF and record, the results are back to normal (highs are intact - track sounds same as original), but as soon as i record with split output ON, the quality drops noticeably. i have tested it with different tracks comparing the same sections and all lose the high frequencies.
is this just me? maybe its because i am on an phone 4? can it be anything to do with NOT using an audio splitter?
