Rowland Continuum 500, RCA vs. XLR

Simontju - Continuum 500 is a class D creature. It cannot be balanced input to output. It has balanced inputs and fully balanced pre but it's converted to duty cycle (time) in analog modulator to finally drive full Mosfet bridge.

Kijanki - " Continuum 500 is a class D creature. It cannot be balanced input to output" - is nonsense, sorry.
Amplifier can be in fully balanced or single ended mode regardless if it modulates amplitude or pulse width.

As I wrote - I operate my two monoblocks (class D) in fully balanced mode: from input to output. Otherwise, I spent $10k (retail) on 2nd amp without having a slightest understanding of what I am doing...

Simontju - I just cannot imagine how. Output is not balanced (H-bridge in not same as "bridged"). Would you suggest two separate analog modulators? And each of the driving what? Feedback connected where? It wouldn't make any sens.

A little more about H-bridge. 4 Mosfets switch output between V+ and GND (changing polarity). It is done only to avoid using bidirectional supply and has nothing to do with being bridged.

If you use second monoblock to run bridge mode than I think you're mixing balanced with bridged. You could possibly put two monoblocks for each channel and connect one wire of balanced input signal and the GND to each input (+ phase reversing circuit) but it would not make any sense. Am I missing something?

" suggest two separate analog modulators?"
Yes, and everything else - two monoblocks, not one monoblock

"...You could possibly put two monoblocks for each channel and connect one wire of balanced input signal and the GND to each input (+ phase reversing circuit) but it would not make any sense. Am I missing something?"

Yes, I use single ended input so I use hot (+ phase reversing) and GND. If I do not to phase reversing then I have...no music i.e. signal cancellation.

Moreover - I carry thes signals directly to speaker binding posts: red - to positive and black to negative....

Balanced signal transmission, BY DEFINITION, is transmission of two signals, equal in magnitude and opposite phase - ITS DEFINITION, I have nothing to do with it...

Also, my amps are not ICE-based if this of any logic....I wound't know...

Simontiu - Continuum 500 couldn't be balanced all the way thru because of its output stage (already bridge).

Do you know of any fully balanced (input to output) Class D amps (not counting DIY seettings). I don't even know traditional fully balanced integrated amp - do you know? It is probably not very common.

Your amps must be Channel Island (Hypex based) or other design.

This phase reversal means that it is not fully balanced (am I missing something). In order to create fully balanced system you need to get fully balanced output and connect each of the output signals to separate amps' inputs and connect ground of the preamp to ground of the inputs. Two output signals of balanced preamp are already i opposite phase - no need to reverse. Each power amp has signal related to GND but the output signal depends only on the difference (speaker between amps removes ground dependency). If you need to reverse input signal - it means that at one point you use the same signal to create different polarities and therefore you are not fully balanced - you're just bridged to get 4x power.
