To tell stereo or not, look at IC on the audio board....IC9 = MONO, IC10 = stereo, also to check the STEREO PAL IC 25 label "IP457" for stereo. If those are both there (IC10 and correct IP457)- it's stereo and EMAX may have lost its setttings. Then you need to do service to bring back the settings (reset available for fee from EPR electronics).... As to SCSI- many drives have onboard termination, or may have jumpers but the actual termination resistors may not be there (I have had this situation and had to order the resistors), in which case jumper is useless. for that we need more pictures to confirm it.

Thanks again for your fast reply!Well, the problem seem actually even more complicated, there was no HD inside my EMax II keyboard, so i took a simple old Quantum, that works well in an old MacClassic, but the drive isnt even recognised by the system i tried any SCSI id and he doesnt see it, the drive is now formatted HFS macintosh butim trying to format it for the Emax II of course, but he cant find it, basically its like the SCSI active sensing is dead…the menus inside the Emax are there but the sampler doesnt detect either internal HD or external CDROM, i even tried with an old Apple CD 150 (1x :-)The HD is set on ID 1…I dont understand whats going on, i will now take some pic of the mainboard and the output boardWhat i dont understand in there is that its a model #2212 and i dont see the stereo sampling menu on the screen, i can choose to sample either pri or sec…Maybe the guy i bought this, swapped some board or removed the stereo chip?I'll prepare some pictures nowAs i know Ted that you're the Emax Guru in here, maybe you faced this before?L.Le 7 juin 2014 à 00:48, "Ted Summers djtbs1@...

The HD inside will have termination. you can have termination problems which result in the behavior.

Hello friends :-)
I recently got my hands on a new Emax II keyboard, model 2112, stereo 2MB, and im facing a little problem.
The problem occur when i connect whatever scsi peripherals, like CDROM apple 300e, or ZIP 100 drive or spyrus CF card R/W.
Emax II is on ID 1, when i press : Drive Select and choose SCSI ID 2 where my CDROM reader is, the screen
either got frozen, either it shows black stripes and the sampler reboots.
All works fine, but not the SCSI (external), is there anything wrong, or is there any chip missing maybe on the mainboard ?
I opened the emax to clean it, but as im not an expert, maybe if i send one of you guys a photo of the board,
you might be able to help me more?
Maybe i am connecting things wrongly ? i tried with terminated plug and without but it either freezes the machine either puts him back into a reboot…
Thanks in advance for your help
Laurent
