You can link multiple StudioLive mixers together. Up to 4 StudioLive mixers can be linked for a total of 96 channels.The StudioLive 24.4.2 from PreSonus is an extremely well-thought out and versatile 24-channel digital mixing console with an integrated 32 x 26 FireWire computer audio interface. While other digital mixing consoles tend to rely heavily on menu-driven LCD displays and hardware controls that get assigned to carry out several different tasks depending on what mode they're in, the StudioLive offers a new approach with an incredibly logical layout and a wealth of dedicated controls.The name StudioLive really explains a lot, because this mixer has been designed to be very useful in the recording studio, and a powerhouse of a live sound reinforcement mixer. In the studio, the StudioLive acts as your FireWire computer audio interface and is capable of handling 32 simultaneous inputs. It's compatible with Logic, Sonar, and any ASIO and Core Audio DAW software. There are 24 XLR inputs that all have XMAX microphone preamps, inserts, and direct outputs, and every channel has a dedicated Fat Channel dynamics and EQ section.Fat Channel is a full-featured channel strip that's available on every channel, aux send, sub group, and the master on the StudioLive. You simply press any channel's "select" button, and in an instant you have access to that channel's high pass filter, 4-band fully-parametric EQ, compressor, limiter, and gate/expander, which all feature dedicated, clearly-defined controls. Presonus took this capability a step further by making the Fat Channel functionality available as a creative tool in computer recording. You can use it while recording into your DAW either pre or post fader, and you can send your tracks back through the StudioLive using its 2nd FireWire port as a return and perform an 18 channel real-time mix down with full Fat Channel functionality.Equally well-suited for live sound mixing, the Fat Channel functionality is incredible
