I drive a Beyerdynamic DT990 (250 Ohms) through a portable head amp from my iPod Classic with LOD cable. A couple of days ago, the left channel line output dropped dramatically.
- tried several LOD cables, all the same problem, rules out faulty cable
- tried cleaning dock contacts, did not help
- tried other sources into amp, everything fine, rules out faulty amp
- reinstalled iPod software, did not help
Headphone output on top of iPod is fine however.
My question is: is there any way to alter channel volumes/outputs/balance in an iPod? With a little, obscure, unknown app???
Help is appriciated!
