Dsp (Internal) - Innosonix MAXX Series Manual

Chapter 4. DSP (internal)
A DSP is a digital signal processing chain inside the FPGA that calculates the volume
control, filtering and limiting parameters on the selected Input Source. There are as
many DSP channels as amplifier outputs on the MAXX device. DSPs are "hardwired" to
the corresponding amplifier, e.g. DSP channel 1 supplies an amplifier that is wired to
CH1 Jack on the rear panel.
