Output Gain
The gain of each output is adjustable from +30 dB to –100 dB in 0.1 dB steps. After –100 dB gain is
set to –Inf, which means that output is present, but muted.
Output Polarity
If set to “Norm” output polarity is the same as input polarity, if set to “Inv” the output polarity is
inverted. This can be used to correct polarity errors in the input signals fed to the card.
Tone Frequency
This sets the frequency of the test tone for each of the four tone generators. Each of the four tone
generators TG1 – TG4 can be set to a different frequency, and are available as audio sources for the
embedded or AES audio outputs. The tones can range from 50Hz to 16kHz.
