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.

why call it a Multi Channel when it is only a dual or Stereo Unit?
A shopper
on Nov 25, 2023
Well, according to Meriam-Webster and other English language dictionaries....multi means more than one...multi doesn't indicate how many more than one, just more than one....so Monoprice is correct by saying this is a multi channel unit. Probably for marketing and branding they chose mutli- instead of stereo or dual.

Is this amp capable of 2 ohm loads?
A shopper
on Oct 11, 2023
BEST ANSWER: No, only down to 4 ohms. I have a Parasound 275v2 two channel amp that will run at 2 ohms, but the amp can get hot.

Are the weights and dimensions shown in Full Specs for the shipping container, or the actual amp?
A shopper
on Nov 17, 2023
Does the amp automatically go into a standby mode if no audio signal is detected or do you have to press the front button each time?

Great 2ch hifi music amp!
I love the sound and the build quality of this amp. 22.5 lbs of class a/b goodness. Really like the solid aluminum face plate. With 250 watts at 4ohms of dynamic power this amp is ready. I love the sound of my music with this amp. You could spend 3 times as much, but maybe only the dogs are hearing any difference. Thank you Monoprice for making a 400 dollar 2ch power amp. David
