Thanks, I had a feeling that‘s what they were. They were plugged into channels 1 & 2 line and tape inputs, think it’s because these are the high impedence instrument inputs?
So, I went to the guy’s storage tonight, no RCA jumper links to be found, ugh. So I guess I’m down to start soldering my own jumpers. Hard to believe you can’t find these things anywhere online at all (that aren’t $15 ea!).
Also, he has the MS-16 1” recorder unit, complete with DBX, VU, record and transport units, even the little rolly stand for the record and transport remote unit! All cables, plus several patch bays, lots of XLR snakes and even a 1” tape recorded in 1982 of Judas Priest “Breaking the Law” that was recorded on it! This guy used to own BeeJay studios in Orlando, FL. Said he recorded a ton of 80s bands back in the day.
I think I can pick it up for about $500 total for everything… worth the headache?
