PreSonus StudioLive Series III SE 32R 40-Channel Digital Rack Mixer

The PreSonus StudioLive® SE 32R is a 40-channel digital rack mixer engineered for live sound, monitoring, and recording in touring and installation contexts. Built on PreSonus' proven Series III architecture, it combines 32 XMAX–R recallable preamps with 16 configurable FlexMixes, four dedicated subgroups, and four effects returns–providing the routing flexibility essential for complex mixing environments. Milan–certified AVB networking integrates seamlessly with StudioLive Series III stageboxes, personal monitor mixers, and networked peripherals, while simultaneous 64×64 USB 2.0 audio streaming and onboard SD card recording capture multitrack or stereo feeds without external hardware.

The preamp design delivers professional audio integrity: each channel offers 0–60 dB gain control with 1 kHz CMRR of 65 dB, 94 dB signal–to–noise ratio (A–weighted), and total harmonic distortion under 0.005% at +4 dBu across the 20–20 kHz spectrum. Analogue I/O includes 32 combo XLR/quarter–inch mic inputs and balanced quarter–inch line outputs rated to +18 dBu, whilst per–channel source switching (analogue, USB, SD, AVB) enables flexible signal routing without external patching. The 24 DCA groups provide master–level control across user–defined channel families, critical for managing large monitor or main mixes in real time.

Standalone, monitor mixer, or stagebox modes accommodate different workflow architectures–a single SE 32R can function as primary console, dedicated monitor controller via QMix–UC wireless remoting, or a networkable input stage for larger distributed systems. Virtual Soundcheck integration with Capture software allows playback and mixing of pre–recorded sessions, invaluable for rehearsal, troubleshooting, and line check procedures. The compact rack form factor measures 19 inches wide × 3.5 inches tall × 12 inches deep, consuming only 35 W continuous power, making it suitable for touring rigs and fixed installations where space and power budgets are constrained.
