5.5 Clearing and Freezing Filters
The reference canceller and 1CH filters are adaptive filters. This means that
their filter coefficients are constantly changing to adapt to new signal conditions.
If you want to reset the filter coefficients and have them adapt from a fresh start,
then click the “Clear Filter Solution” button. This will clear ALL the adaptive filters
in both channels.
To “freeze” the filters, which prevents them from further updating their
coefficients, click the “Disable Adaptation” button. This will change the text of the
button to read “Enable Adaptation”. The text of the button is an indication of the
action that will be taken if you press it, not the current status. So, to allow the
filters to continue to adapt again, press the “Enable Adaptation” button (and
again, the text will revert to “Disable Adaptation”).
5.6 Channel Configurations
The MicroDAC 5 can operate in a mono or stereo configuration. Different
reference canceling options are available depending on which configuration you
are working with. The channel configurations can be accessed via the
“Channels” menu.
5.6.1 Mono Configurations
To configure the unit for a mono signal, click the “Channels” menu and select the
“Mono” sub-menu, as shown in Figure 5-3. In mono mode, the primary signal is
always the Left Input and the output is sent to both the Left and Right Outputs.
