HPB High-Pass Filter Bypass Bit.
0 – AC Coupling High Pass Filter Enabled
1 – AC Coupling High Pass Filter Disabled
The STA326 features an internal digital high-pass filter for the purpose of DC Blocking. The purpose of
this filter is to prevent DC signals from passing through a DDX® amplifier. DC signals can cause speaker
damage.
