Each XD3 IP core (52-7550) has one DSP processor included, already. By extending the Core with the optional XD3 IP Router module (52-7540), up to four additional 52-7530 DSP modules for a maximum of Faders, Busses and DSP channels can be added to the device.
All of these DSP modules provide 40-bit floating-point processing for fader channels, channel processing, fixed processing and summing operations. Also additional routing capacities are provided to allow the use of up to 24 Gigabit Audio ports.
Also additional memory for channel delay and program delay are also added with each DSP module.
