One thing I'm having trouble with is deciphering the model numbers on the changers. As near as I can tell, 'CT' is "cassette", 'M' is "multiple" (as in changer), 'W' is "dual well" (in the case of changers, one multi cassette well and one single cassette well) and 'R' is "remotely operated", either by cabling to the receiver or with its own built-in IR receiver, both having the SR symbol on the front panel.
What is confusing me is what (if anything) the digits signify. They don't appear to be in chronological order, but the first (or only in some cases) digit seems to be either a 5, 6, or 7, where 5 is wired remote to the receiver, 6 is built-in IR remote, but what does 7 mean? And is there any meaning to the second digit? Like, is there any difference between the CT-M5R, CT-M50R, and CT-M55R? And so on.
Pioneer SX-251R compatibility question
I have recently picked up an SX-251R as a nice little bedroom receiver, and as a former owner of a CT-M6R cassette changer, I wanted to get a changer for this setup.
The issue I have is that the only changer available locally is a CT-M50R, which has no IR window, but does cable to the receiver. As I still have the CU-TO11 remote that came with the old changer, will the amp recognize it and send its commands to the changer, or am I stuck with the much more limited cassette changer controls on the amp's remote?
