The ease of analog meets the power of digital.

The StudioLive® 32.4.2AI is the perfect 32-channel (32x4x2) digital mixer for live mixing and on-location recording for churches, clubs, corporate, institutional, and other installations.

Easier to use, better sounding, and flawlessly integrated with state-of-the-art software, it operates so much like an analog mixer that even novice customers will immediately feel at home. Naturally, the StudioLive 32.4.2AI features our highly respected XMAX Class A mic preamps—even on the Talkback input!

Configurable, flexible, and expandable.

StudioLive 32.4.2AI has 14 aux buses, 4 subgroups, a talkback section with high-headroom, Class A XMAX microphone preamp; extensive LED metering; mixer scene save and recall; 6 Quick Scene buttons; and channel-strip save/recall/copy/paste. Eight dual-mono (16 total), 31-band, graphic EQs are on the aux sends and the main output bus.

Each channel features an XLR mic input with XMAX mic preamp, individually switched 48V phantom power, ¼-inch balanced line input, direct outputs, and insert point. Channel, subgroup, and main levels are set with 100 mm faders.

Note: The minimum system requirements may differ for DAWs other than Studio One. Please check the requirements for your DAW of choice with its manufacturer.
Note that the speed of your processor, amount of RAM and size and speed of your hard drive will greatly affect the overall performance of your recording system. Also, a more powerful system (faster processor with more RAM) will allow for lower latency (signal delay) than you might experience while monitoring audio signals.
