Arrakis console, eh?  My condolences.  Anyway, here's a suggestion.

1. Think of the 8 track as 4 2-track recorders operating in tandem. Hook
the output of the console to the recorder as follows: Left to 1,3,5,7;
Right to 2,4,6,8.  Hook the outputs from the recorder (in stereo pairs)
to the 'B' inputs on the console. i.e.: Ch 1 & 2 to console input 3B;
Ch. 3 & 4 to console input 4B, etc.  (this is assuming that inputs 1 &
2 are dedicated mic inputs you don't want to share).

2. This arrangement has a lot of advantages - primarily ease of use by
those with no multitrack production experience. It also has a number of
disadvantages - primarily the lack of any pan function, and the need to
tie up 2 channels for purposes such as voice-overs & sound effects that
could easily be recorded on 1 channel. However, think about what the unit
will be used for: producing promos & IDs, possibly simple music recording
projects, etc. These really don't require the efficent use of all 8 tracks.
Just a starting point. Good luck. Call me if you want. I'm pretty good at
the efficent use of marginal resources & the Arrakis console is as marginal
a resource as you're likely to find. I know - I deal with 2 of them every
