4000 plus / studio a / studio d

whats the difference between the various models of the 4k?

i know that the
The IB-48P version has the 8 out option,the IB-4ADT version has the adat option ,the base model has neither the adat or 8 option and the the LE verion has no cd rom,only 16 meg memory, and neither the adat or 8 out option.

but it appears that some have a larger hardrive than others....
can anyone elaborate on the finer details if any??

thanks folks!!

the oldest ones came with a 40gig then 60 gig now 80gig. its only be cause that was what was widely available at the time with balence of cost but thats it

Actually they were released in the US with 60 gig HD's and then they started the MPC plus with 80 gig HD's with digital I/O.
Sudio A has the 8 Ib48p
Studio D has Ib4adt

For those that don't know, the above information is for the US models only.
