Hi flo+list. for the general interest here is the issue. the hammerfall aeb8-I has switches on the circuit board. each channel sensitivity can be set by setting jumpers. there are two jumpers close to the input jack of each stereo input, eight in total for 8 channels. I had the vision that the option was in the configuration dialog, but that is not the case for hammerfall 9636, though it was for 9632. thank you, have a good day. greger > > > Flo > -- > Machines can do the work, so people have time to think. > public key 6C002249 x-hkp://wwwkeys.eu.pgp.net > > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Microsoft > Defy all challenges.
