Does anyone remember what the difference is between the Optimod 9000 (black front) and the Optimod 9100 (beige front) ?
Is there a dramatic difference in the sound of each unit ? Or...does the newer 9100 unit just have "newer chips"?
I know the Optimod 9200 digital box has replaced these units at many stations. I've put in a few myself.
It's been quite a few years since these analog units were prevalent...and I've forgotten the difference.
Can anyone refresh my memory???
