Krell has an IR In jack on the back of it. No Reason to ever put an emmitter on the front.

Think about controlling the Runco RS-232 A Xantech IR-RS232A works just fine.

I've opened up components in the past to put the emitter inside..... But also check the back of all these units... Even if it doenst have a standard IR in... Xantech makes adaptors for SR Link, RC-5, and other protocals.

Xantech used to make a "Blaster" that worked well in this situation.... Al gone now for some reason... Look at Speakercraft. The AT-1.0 and a IRE5.0 may be your best bet if you want to stick with the Blaster Option.
