iMac Users - Help No Output to System

I'm coming out of the iMac (iTunes) with Optical Toslink into a Cyro-Parts signal converter (optical to Coax) but nothing comes out on the system end. I'm going into a Krell KAV 300i integrated amp. The optical "out" on the iMac definitely works for headphones so I suspect the signal converter. When the signal converter is engaged the iMac "Sound" page indicates "no output controls". Perhaps you know something that I don't about passing the signal through to the system.

Plug the fiberoptic into the minijack and ensure the other end is glowing red. If it is not, then you'll have to enable the optical out as Mb9061 suggested.

Which DAC are you using? The KAV-300 does not have a built in dac, it's an integrated amplifier. A fiber to coax converter merely converts from SPDIF fiber to SPDIF coax, no actual digital to analog conversion is taking place. For that you'll need a DAC.
