Hi all,
I just got me a Roland RD2000. I´m pretty new to the piano, but I sold my studio piano, which was a pain in the neck to move (I move a lot) and decided I needed something lighter. Anyway, could not have made a better choice.
I have a few questions, hoping the experts will help me.
I connected the Roland to a set M Audio BX8a speakers using XLR cables with a MONO 6.3 adapter plug. I wonder if that is Ok, or if I ought to get STEREO instead, since XLR has 3 pins.
I also have a spare couple of adapter plugs, also MONO, with which I could instead use the plug output instead.
Would you recommend the latter, or using XLR is fine?

Doesn’t that monitor have an xlr input connector? Why are you using an adapter?

Ordered same board. Should come in a week.
Do you play classics on it? What do you think about this video?

The RD2000 probably has two XLR "Line Out" jacks:

. . . Each jack is monophonic -- one for the Left channel, one for the Right channel.

If each monitor has a 1/4" phone jack "Line In", what you've done should be OK.

I would also ask Purdy's question:

. . . If there's an XLR "Line In" jack on each speaker, you could eliminate the adapters that you've using.

The three pins on an XLR connector (for every device I've seen) are:

. . . ground;

. . . signal "+";

. . . signal "-"

The two "signal" pins carry a "balanced" signal, and that arrangement is more hum-resistant than the 1/4" phone jack inputs that you're using. But if what you did works, there's no compelling reason to change it.

Yes there is a compelling reason Charles, help thee economy along 😀

These seem to have balanced XLR inputs and also balanced jack (TRS) input. It should be best to connect each speaker with an XLR cable or a "stereo" jack (TRS) cable (actually, two signal lines but for a single channel). But it should be okay with your cable if you're happy with the sound.
