Discussion Of Results
This card's retest, using the recent 4.0.1 (beta) drivers, shows somewhat poorer performance than has been seen in the past, mostly due to the fact that with these drivers, the input level control was inoperative. Therefore level setting was not optimized as fully as it would have been had an operational input level control been availible.
