It won't work. If you want the IR control of both the Arcam and the Krell, you need to be able to generate different IR signals going into each. You can get little individual emitters to stick on each component, but the pronto is still going to cause each of the emitters to emit the same IR codes at the same time. That is what prpixel is talking about--you need to be able to individually address each IR emitter. The pronto won't do that.
