· The APA is a hardware solution that lets you easily run multiples of Waves most CPU-intensive plug-ins. For example · the APA32 lets you run 6 IR-1 Reverbs · or 9 Linear Phase Equalizers · or 12 C4 Multiband Parametric Processors at 44.1KHz. The APA44-M is even more powerful · giving you up to 30% more plug-in power than the APA32. What's more · the APA units don't require a PCI card or a Firewire or USB connection. You simply connect them to a standard Ethernet port · install the new NetShell software · and cut loose.
