When PreSonus began engineering the new StudioLive 64S, our goal was simple: to provide the most powerful 64-channel digital mixer in its class, without compromising the performance and intuitive workflow that are the hallmarks of the StudioLive Series III mixer design philosophy. This meant we needed to optimize the dual-core FLEX DSP engine and expand on its design to accommodate an impressive 134 mixes with a total of 4890 inputs that were required to deliver a 64-channel mixer worthy of the StudioLive name.
The all-new quad-core FLEX DSP engine in the StudioLive 64S digital mixer provides an unparalleled amount of processing power for its class. We began by combining two DSP engines dedicated to input processing with a separate DSP just for mixing, and a fourth DSP to run the eight onboard FLEX FX. To provide the flexibility that modern audio engineers demand, we designed a dynamic audio routing matrix with 26 internal audio routers capable of patching audio to 1178 unique routable destinations.
The result is a 64-channel mixer that allows the free routing of any input and mix bus with 32 FlexMixes that are individually configurable as aux, subgroups, or matrix mixes. Unlike other mixers in this class, StudioLive Series III mixers support matrix mixes created from every input and bus, even on the new StudioLive 64S.
Because of the performance optimizations necessary to create the new quad-core FLEX DSP engine, the dual-core and single-core FLEX DSP engines were upgraded to support a new Project and Scene management system for more flexible storing and recall of all routing and mix parameters; Fat Channel plug-in models on every channel and bus; a whopping 128-channel (64x64) audio interface; and much more. Because of the dynamic design of the FLEX DSP engine, every new feature packed into the three new 32-channel StudioLive Series III S models is also available in the free FLEX DSP 2.0 firmware upgrade for StudioLive Series III Blue and rack models.
