sorry cant really help - but, id be interested to hear how you get on with the 4ms row power, as Ive got a new (portable) case coming, and need power for it… and had consided this !
Currently, I have the SSP in a 4ms 64x pod , with the supplied 4ms power / psu. I’ve not noticed any noise.
note: I dont bother with an output module - I go straight into a mixer, or my octatrack.
I do love having the SSP in a small desktop unit, its great to be able to bring it close to me when Im working on patches - sometimes take it away from the rest of my setup to do something on its own or with my computer.
only drawback was I needed some longer patch cables … though if you have 4000hp, I guess you have a ton of these
anyway, Id like to hear how it goes - esp, if you set it up with a few other modules - as Ive been considering this with my new portable case. (rather than having the SSP entirely on its own)
I’ll probably buy a 4ms row power 45 (?) when the case arrives as I need power anyway, if it doesnt work, no big issue, I’ll continue with the SSP in the pod 64x as im happy with that anyway.
