I'm integrating an MRF-350 base station with a Krell S-1000 processor and I have a question about the RC-5 IR connector (which is a DC type jack) on the back of the Krell. Does anyone know if this is a proprietary connector on the Krell or can I simply solder up a 3.5mm to DC cable and then have it work out of one of the ports on the MRF?

I've never managed to get the RC5 connection to work, and I have tried it in the past, however, I think the last time I tried, I had the wrong sized end. I sell Krell, and I love the quality of sound that their products produce but they have a lot of weird stuff like that RC5 connection. Get rid of it! Put a regular freakin' IR IN on this thing, please! Who Uses the RC5?

I finally called Krell service and they told me that I can find all the info I need in the instruction manual. When I told them that there is no info in the manual they finally told me that the RC-5 jack takes a DC plug and it needs to be wired with the center as negative. I tried that and had no luck and I'm reluctant to give them another call seeing that they were difficult the first time I called. You'd expect better customer service for a $6,000.00 piece of equipment.

The krell equipment is a joke when controlling via the rear IR input. Bury an emitter in the unit or why the heck aren't you using 232 from an MSC? We ran into problems with their IR protocol with Crestron a few years back (we were out of 232 ports on the processor and tried IR input...no luck); ended up tossing an emitter in the chassis and calling it a day.

I'll probably get the new MRX-1 when it's available so I can use 232.

232 is definitely the way to go with Krell products. The volume control is a little tricky however. It'll take some tweaking to make work right. When you get there, drop me a line if you need assistance.
