In addition to my (Answered) question about the XLR inputs, I got an answer saying it's for convenience, I Think this is besides the point of my question. I asked what is the point of having XLR Unbalanced inputs in terms of the Balanced or Unbalanced ability / spec, many other known Amplifiers with XLR inputs are 'BALANCED' for a reason, to have a BALANCED connection and use XLR not just for convenience but to get the signal in Balanced 'form' --- Please elaborate why you chose to use an Unbalanced XLR connection on these lesser / more budget amplifiers, and not Balanced(I think a lot of these buyers of these new amps think they're getting balanced inputs)..?

BEST ANSWER: Convenience. Many amps are out there with XLR inputs that are not balanced inputs. Why would you expect balanced inputs on these "lesser / more budget amplifiers"?

So the XLR is convenience of having an XLR connection without Balanced ability, I understand. - if you check the 'why I Bought this item' section, some are mistaken thinking it's a Balanced connection because it's XLR. This isn't my mistake I read the page / info about unbalanced XLR. I guess it is a mistake to think if an AMP has RCA + XLR, to think XLR is automatically going to be Balanced. why not just have RCA then I'd say. Thanks for responding.

BEST ANSWER: Hello and thank you for your question. The channels are independent of each other, so it would still be 90 watts per channel.
