Alesis ML-9600 Schematic

[rf7]

Anyone got a schematic for this unit?

[Enzo]

What is it?

What did Alesis say when you asked for it?

[rf7]

It's the Master Link. I guess I'll call Alesis and see what they say, I did not even try that yet.

[Enzo]

I don;t know what a master link is. I'll google it and find out more.


I see, a hard disc recorder. When you call them, I would suggest having a specific reason for wanting the documentation. Give them a reason to want to send it.

[rf7]

They emailed me a service manual, very nice!

OK good, because I was just about to tell you that we have serviced hundreds of Masterlink units and have the manual if necessary. Probably parts too. Most of the time, the problem was a bad HD.

[Enzo]

Are the hard drives in them plain old generic HDs? Or is there something custom about them.

I find that buying hard drives from Korg or Tascam or whoever usually includes a $150 price tag. I can buy a replacement from my local computer store for $40.

I had to replace a CD burner drive in something and went down to the computer store once and it was remarkably cheap. Then I tried it once for a TAscam something, and their CD drive had a custom interface, not the standard computer interface. I was stuck getting it from Tascam that time. Grrr.

Floppy drive - $9 new at the computer store.

Speaking of hard drives. lately I have been finding dead units like HD recorders, with power supply loaded down. By unplugging subassemblies I'd narrow it down to the HD. Dead short across the power input. Inevitably it is a shorted protective diode near the connector. (HD will run without it, so you can remove it to see if the HD works otherwise) Quick fix and back on the road, and whatever was on the disc is intact.

Yes Enzo, the internet is our friend. I almost NEVER purchase it from the manufacturer unless it is under warranty. I'll find it online. We did the same thing with Mackie D8B digital mixers. They are essentially a PC with a worksurface interface (a BIG mouse!), and we bought motherboards, processors, firewire cards, almost EVERYTHING online, and continued to do so when Loud Technologies cut off the parts pipeline for these.

Agreed. In addition to that, this one's display is dead. The voltages are all there, but there is no illumination of the big display panel. The leads from the display panel are soldered to short pieces of bus wire soldered to the pcb pads. Very weird.

Mine just died. I saw your post, clipped the diode and now I'm back in business. Thanks Enzo!!!!

Does anyone have service manual/shematics for this unit? I need to know the voltages coming out from the power supply that is dead. Two of them are probably 5 and 12 volts (hard drive), what are the last two (white and blue wire)?
