duet 2 loopback

i was wondering why i get this 'ripple' effect when doing a loopback with my Duet 2. (balanced out > in, using Mogami 2534 XLR > 1/4" TRS cables)


(44.1 kHz sample rate, 512 buffer size)

also, i was wondering if it was typical to have low level 'noise' from this type of cable/loopback. this is the loopback connection with no signal passing through...it has a 'harmonic' or tone. (it does not always show up @ the same frequency) is this 'OK' or do i have a problem (interference?) and/or need different cables?
and when i unplug the cable, the 'tone' goes away and i have nice clean noise floor...so clean you could eat off it...


(...this is a screenshot of 'realtime' analysis, so level values are +/-...)

*side note: and why is Signal Scope saying Duet2 has 2 ins and 4 outs...looking at the Duet2 it seems it is the exact opposite of that...

yes, when i try unbalanced cables there is a lot of interference...
it actually picks up me tapping on my desk when i run a loop with 1/4 unbalanced cables...(no mic involved...)
