Model:

​ DSi 2.0 Series

Issue: ​

​When using Audio Architect to configure DSi 2.0, the following Bug has been discovered.

The Allpass 1 and Allpass 2 Filters are staying active even when the Band ON/OFF buttons are set to OFF on the Input (User EQ).

This happens if the Allpass filters have been set to ON.

Steps to replicate the issue:

  • Select first EQ (left side of Crossover) and apply ON.
  • From the individual BAND 1 to 8 select Allpass 1 or Allpass 2 and apply ON.
  • Then switch over to OFF from each BAND and the display shows OFF but Allpass is still working.
    ​

If a filter is changed to a different type like Bell or Low Shelf and set to ON, the Allpass1or Allpass2 function is released.

Workaround:

Turn the band ON/OFF button to ON and then clear the filter. This sets the filter type to Bell and sets Gain to 0.
