So this might be another wrong category thread by yours truly but need some help on my amplifier I'm planning. I'm going to build an amplifier using the Hypex nc-400 modules and on the datasheet they recommend using balanced input. Now I'm asking a simple question and that is: will using unbalanced input significantly effect the sound quality? If it barely effects it I can tolerate but if it's significant I would like to build it right, even though it would mean having to convert my output source to balanced. Anyways it's a lot of work for a kid such as me to build an amplifier so I want to make sure I do this right. Any replies are very welcome I really need to get this straight before I make a blueprint and tabulate my costs. Thanks!

Maybe, maybe not, but do yourself a favor and build it balanced. Then you can always build cables with RCA one end and XLR in the other, which will ofc make it unbalanced in the end, but then you can always upgrade to balanced input at some later point.

Btw I've built a Hypex amp using the UCD400 OEM (equal to the ST). I have both RCA and XLR inputs mounted on the cabinet, but only the XLR are wiring at this point. -It sounds amazing, but havent tried if i would hear the difference between balanced/unbalanced. It depends a lot on the cable lengths and ofc if you have a some noise source nearby.

Take a look on these documents ;)

Go to a PA equipment retailer.
There's lots on Amazon and Ebay and similar.
They will sell you GOOD Quality XLR cables for a fraction of the cost charged by the exotics purveyors.
there's a link inside that advert: cables 4 less.co.uk

Did you ask Hypex? They are here on the forum and generally reply quickly.
