I guess they are thought as +4dBu/-10dBV (= ~12dB) switches. Also the driver says SPDIF input is on the 0202 daughter card, but at least in my card it's on the 1010 main card. I have a 1212M V1 card. If anyone has one of these cards, can you confirm that these are true for other/all cards of the series? Thanks Camilo
