Outboard Gear ISO: Legacy graphic eq solution

[KensAudio]

Way back in college (early 90's), the student-run radio station found a unique graphic eq.
It was a single rack unit high, and with the flip of a switch, it could act as *either* a single channel 31-band GEQ *OR* a two-channel 15-band eq.
I've been digging, but I can't remember the manufacturer or the model name/#.
Can anyone help me find this versatile little problem solver? Has any other maker made such a gizmo?

It's not urgent, but I see possibly being in the market for such a thing at a later stage.
Thanks,
- K

Dbx 1531. I'm sure Peavy made one as well.

A dbx 1531X. Discontinued, but used ones still kick around.

Thanks for the quick responses. I appreciate this CB community.
Found a couple images / used ones to gawk at online. It appears (probably due to the era it came from) that it's a bit bigger (i.e. deeper) than I'd hoped to fit in my kit, but I'll keep this in mind.
Thanks again.
