Carver ZR-1600 amplifier


My musician son left a Carver ZR-1600 amplifier behind when he moved to Nashville.  Looking around the internet I've seen these amplifiers modified to include RCA inputs.   Before I pop the top, and get to soldering, I'd like to give the amplifier a listen.  But for now, can I use (Amazon sourced) a pair of Monoprice XLR Male to RCA Male Cables?
