Peavey BI208 - A Bass Oddity?

[SamPlaysBass]

I was recently given this bass amp as the person I had it off wanted to make space in their garage. In all honesty, there’s not a great deal online about it other than it looks like Peavey’s version of a Trace Bright Box.

 

It’s dusty, covered in cobwebs and not the best looking, but I was wondering if anyone had any info on them? They seem to originate from the late 80s. There’s an input on the back and it works just by plugging straight in the back - no EQ section here! 
 

Any info?

Made in UK. Real mystery machine. 208 = 2x8'' speakers, in a self powered box = an idea before its time.

It was intended for use along with a TNT amp and cab as a bi-amped low frequency/high frequency rig. Another example: https://reverb.com/item/21762989-peavey-2x8-100w-powered-bass-bi-amp-cabinet-late-1980-s-early-1990-s
