Professional Rack Storage for Streamlined Studio Workflows

The On-Stage WSR7500B is a rackmount cabinet designed for creators who need practical, organized gear access without compromising studio space. Whether you're a music producer, podcaster, DJ, or content creator, this 12U sidecar cabinet integrates smoothly with modern workstations, offering a compact, professional way to house your most essential rack gear. Its clean finish and workspace-friendly dimensions make it a natural extension for both personal and commercial setups.

Where This System Excels

Rack Integration Without the Footprint: Add essential outboard gear, interfaces, or processors directly beside your desk — no separate racks, no clutter.

Modular Studio Layouts: Seamlessly aligns with WS7500 Series workstations for an expandable, matched platform with unified aesthetics.

High-Traffic Production Spaces: Ideal for control rooms, home studios, voiceover booths, and DJ setups where efficiency and accessibility matter.

Gear Consolidation: Brings multi-device configurations into a centralized hub, reducing desktop sprawl and cable chaos.

How to Deploy the WSR7500B

  • Standalone: Place beside a mixing station, broadcast table, or workbench for dedicated rackmount access.
  • Side-Mounted: Position to the left or right of a WS7500B desk to extend usable surface area and keep racks aligned with your workflow.
  • Under-Desk: For setups with taller desktops or corner workstations, the WSR7500B tucks neatly beneath the primary worktop.
  • Stacked Systems: Use multiple cabinets to build tiered rack towers for larger outboard or stage systems.
