Does DCN23 have a DC-blocking capacitor at the output?
No – DCN23 do not have any DC blocking capacitors as our amplifier modules have it at their input. It is highly recommended to have a DC-blocking at the input of the attached power amplifier to prevent the amplifier from either putting out DC or going into protection mode. If capacitors were placed both at DCN23 output and at the input of the amplifier you would get more group delay and a higher High-Pass frequency.
