With Greg, set up and tested an old phono pre-amp acquired from the CALL. Appears to work OK. Needed a reset of the FW410 to wake up its sp/dif out. Eventually these inputs should be moved from Channel 1 & 2 of the desk to a stereo channel such as 15/16, freeing up the first two channels for mics only; mics need to be in one of the first eight so they get preamped.
