PreSonus StudioLive Series III SE 24R 24-Channel Digital Rack Mixer

For productions that require expanded input count and deeper routing in a rack format, the StudioLive Series III SE 24R delivers large-scale capability in a streamlined 2U chassis. This 24-channel digital rack mixer combines 24 fully recallable XMAX-R mic preamps with a 40-channel processing engine, 26 mix buses, 16 configurable FlexMixes, four subgroups, four FX mixes, 24 DCAs, integrated 64x64 USB recording, onboard SD capture and Milan-certified AVB networking. With 32-bit floating-point internal processing and system latency as low as 1.9 ms, the SE 24R provides console-level control for complex live sound, broadcast and studio recording workflows.

24 XMAX-R Preamps With Full Fat Channel Processing

Twenty-four XMAX-R mic preamps offer up to 60dB of clean, recallable gain, supporting full bands, expanded instrument rigs and multi-source broadcast environments. Every input and bus includes Fat Channel processing powered by the FLEX DSP Engine, featuring nine State Space modeled EQ options and ten vintage-style compressor models. Engineers can shape tone and dynamics across the entire mix without external hardware, then store and recall settings with precision across sessions and venues.

16 FlexMixes and Advanced Bus Architecture

The SE 24R provides 26 mix buses, including 16 FlexMixes configurable as AUX mixes, subgroups or matrix outputs. Four dedicated subgroups and four FX mixes with stereo returns expand routing flexibility for monitor sends, streaming feeds and distributed audio systems. Twenty-four DCAs enable efficient management of large channel counts, supporting fast adjustments in demanding production environments.

64x64 USB Interface and Integrated SD Recording

Serving as both a live sound mixer and a high-capacity USB audio interface, the SE 24R supports 64x64 USB 2.0 recording and playback for full multitrack capture. Onboard stereo SD recording enables direct 24-bit WAV capture at 44.1kHz or 48kHz without additional hardware. Integration with PreSonus Capture allows Virtual Soundcheck workflows, while per-channel source switching between analog, USB, SD and AVB supports hybrid production environments that combine live inputs, playback tracks and networked audio.

Milan-Certified AVB Networking and System Integration

Milan-certified AVB networking enables seamless integration with StudioLive Series III consoles, NSB stageboxes and EarMix 16M personal monitor systems. Dual AVB ports provide reliable network distribution, and optional AVB-D16 support adds Dante connectivity when required. The SE 24R can function as a standalone digital rack mixer, remote stagebox or dedicated monitor rack within larger AVB-based systems. Universal Control allows complete wireless operation with Offline Editor support, and QMix-UC gives performers personal monitor control from mobile devices.

2U Rack Design for Touring and Installation

Housed in a rugged 19", 2U chassis and weighing 10.8 lb., the SE 24R is engineered for touring racks, broadcast facilities and permanent installations. Balanced XLR/TRS connectivity, comprehensive routing and integrated recording tools make it a scalable foundation for modern production systems. For engineers who need expanded input density, flexible bus architecture and full studio-grade processing in a rackmount format, the PreSonus StudioLive Series III SE 24R delivers professional control without excess footprint.
