Millercarbon is correct, but you do have options. One option is building a small box with a volume control pot and a couple of RCA jacks in it and plug it into the tape loop circuit of the preamp. Tweak it to match the CD volume, then hit the monitor when you listen to phono and never have to mess with the volume control again. Another option is getting a phono preamp with adjustable gain. And, of course, the easy option, just live with the annoyance, which is what I do.
