I have a Piezo-stack amplifier that needs a DC bias on the input sound signal. Input ranges 0-1V, 0-2.5V or 0-10V. Adding a DC to the sound signal in Sigmastudio only last for a short time (DC decay after setting).
Is there a way to have the output DC-coupled? Is there a good way to add a DC on the signal with an external voltage source?
I use one of the 12 Audio Output channels, see below.
