b. If you have input channels set to any rate other than Auto Mode , the Mute option is recommended. The
output of the card would then mute if an incorrect data rate is applied to the input, or if the input signal
became too weak for the input equalizer to compensate.
The channel outputs are muted if the input
signal degrades to the point that the input
EQ can no longer guarantee error-free
performance

the input stage
