Circuit fails to acquire or play out filtered signals correctly

Tech Note: TN0172
Product: RPvdsEx
Version: <= 58
Date Added: 2005-03-10


The MCBiquad does not work with an nBIQ value greater than one. The signal output is zero.


Set nBIQ to 1. If a higher Biquad number is required, gang multiple MCBiquads together.


Upgrade to TDT Drivers v59 or greater.
