BOSS RC-505mkII Loop Station - Professional 5-Track Tabletop Looper

The BOSS RC-505mkII Loop Station is a next-generation tabletop looper built for beatboxers, vocalists, and multi-instrumentalists who demand professional-grade tools for live performance and studio creation. It delivers five simultaneous stereo phrase tracks, 32-bit AD/DA conversion with 32-bit floating-point processing, and up to four simultaneous Input FX and Track FX — making it the most powerful and flexible tabletop looper BOSS has ever produced.

For performers searching for the best tabletop looper for beatboxers or a professional loop station with XLR inputs, the RC-505mkII raises the bar with two balanced XLR mic inputs with phantom power, dual stereo line input pairs, and three stereo output pairs — delivering studio-quality signal routing without external gear. Long-time RC-505 users comparing the RC-505mkII vs the original will find enhanced faders with longer throw, per-track FX and Track buttons, and an expanded effects library with 49 Input FX types and 53 Track FX types, including new vocal harmony effects unavailable on the predecessor.

The RC-505mkII integrates seamlessly with DAW workflows via USB audio and BOSS Tone Studio software, enabling WAV loop import and export, phrase backup, and pattern management. Deep MIDI control support and two external control jacks — each accommodating up to two footswitches or an expression pedal — make this looper equally at home on stage or in the studio. With 99 memories, 200+ onboard rhythm patterns, and 16 drum kits for synchronizing loops, the RC-505mkII handles everything from spontaneous stage performance to meticulously crafted loop compositions.

Key Features of the BOSS RC-505mkII Tabletop Loop Station

• Five Simultaneous Stereo Phrase Tracks: Enables complex, layered loop performances with independent volume faders and dedicated REC/PLAY, STOP, FX, and TRACK buttons per channel — giving performers hands-on control of every layer in real time.
• 32-Bit Floating-Point Processing: Delivers class-leading audio fidelity across the entire signal chain, preserving dynamics and detail whether recording vocals, instruments, or processed loops.
• 102 Onboard Effects Types: Provides 49 Input FX and 53 Track FX types — including new vocal harmony and Electric FX — with up to four effects active simultaneously in each section and four quick-access banks per section for instant recall.
• Dual XLR Mic Inputs with Phantom Power: Accepts condenser microphones directly, with independent EQ and compressor controls per mic channel, eliminating the need for a separate preamp or mixer for most vocal and beatbox setups.
• Expanded Connectivity and Output Routing: Three stereo output pairs with assignable routing, a customizable headphones output for track and rhythm monitoring, MIDI IN/OUT, USB audio, and two external control jacks support complex performance rigs and professional installation.
• 99 Memories with Full Per-Memory Customization: Each memory stores five phrase tracks, effect settings, playback configurations, and control assignments — allowing performers to build and recall complete, show-ready setups instantly.
• Customizable Controls and Mark Back Undo/Redo: User-assignable FX and Track buttons respond to press, hold, or double-click actions; the new Mark Back function enables instant jump-back to a previous loop state during live performance without interrupting the flow.
