Hantra,
Currently, QSC does not manufacture amplifiers with RCA input connectors. But have no fear, our new series of amps, the SRA line will have RCA connextors, as well as XLR and our DataPort input. We are expecting to release the SRA series very soon. There will be three models to start, ranging in power from 200W at 8 ohms to 725W at 8 ohms.
