The PreSonus StudioLive 24R is a powerful and versatile 24-channel digital rackmount mixer designed for professional live sound, recording, and broadcast environments. With an impressive set of features that cater to the needs of both sound engineers and musicians, the StudioLive 24R offers a complete solution for mixing, recording, and routing audio. Compact and flexible, this rackmount mixer is perfect for both small and large-scale productions, providing high-quality audio performance and exceptional control over every aspect of your mix.

At the heart of the StudioLive 24R is the PreSonus FLEX DSP Engine, which powers 40 mixing channels, 22 mix buses, and a staggering 270 simultaneous processors. This powerful engine delivers all the necessary tools for professional audio processing, including high-pass filters, gates, expanders, compressors, parametric EQs, and more. Every input and bus channel on the 24R features the iconic Fat Channel processing, which includes modeled vintage-style dynamics and EQ plug-ins that can be loaded on every input channel and output bus for enhanced sound shaping.

The 24R mixer features 24 local, digitally controlled XMAX mic/line inputs, and 6 FlexMixes, which can be configured as aux, subgroup, or matrix buses. This versatile routing capability allows sound engineers to manage complex audio setups with ease. Additionally, the unit features 128 channels of USB recording (64x64), making it an ideal choice for multitrack recording in the studio or live settings. The onboard SD card recorder also allows for easy recording of your main mix, with true Virtual Soundcheck mode for seamless playback during sound checks.

For those who require expanded connectivity, the StudioLive 24R is equipped with AVB networking (64x64) to connect with other mixers, stage boxes, and personal monitor systems. It is compatible with PreSonus NSB-series stage boxes, EarMix 16M personal monitor mixers, and other StudioLive Series III consoles, making it easy to scale up your system for any size production. The integration with Capture live-recording software and Studio One for full integration with your recording and production workflows ensures that you have complete control over your live and studio recordings.

The StudioLive 24R also offers comprehensive remote control capabilities through the UC Surface software, which allows you to manage every aspect of your mix from a tablet, iPad, or Windows touchscreen computer. This user-friendly software makes controlling your mixer as intuitive as mixing on physical faders, providing you with flexibility and ease of use from anywhere in the venue or studio.

With 4 FLEX FX slots that include legendary reverb emulations, delays, and other effects, the StudioLive 24R ensures that your sound is polished and professional, with a rich, dynamic feel. The system also supports Bluetooth 4.1 stereo input, enabling easy integration with Bluetooth-enabled devices.
