I have a Zoom HD8CD and two Yamaha HS50 studio montors. These monitors take XLR, TRS, or 1/4" mono inputs. When connecting my HD8CD, I have to use RCA out from it (it is either RCA for the Master Out or headphones), but what kind of connection should I use on the monitor? RCA to XLR, RCA to TRS, or RCA to 1/4"? Are their any differences in sound quality and/or quality of the signal and/or benefits with a specific type?
