From Clunky Carts to a Carousel Symphony: QSC Audio Conducts a 70% Throughput Boost with FloStor Integration

The Client: QSC Audio Products

QSC Audio Products is a leading manufacturer of professional audio equipment, known for high-performance amplifiers used in demanding live and installed sound environments. As the company sustained rapid year-over-year growth, its legacy operations began to limit speed, flexibility, and scalability.

To support continued expansion, QSC partnered with FloStor to redesign facility flow around integrated automation, real-time data handling, and lean material movement.

The Challenge

• Manual Push-System Bottlenecks: Materials were moved by carts across disconnected areas, creating delays, congestion, and inconsistent flow.
• Throughput Ceiling: Legacy methods could not keep pace with sustained growth of roughly 20% to 25% annually.
• Excess Motion and WIP Waste: Fragmented handling drove unnecessary travel, waiting, and inventory accumulation between steps.
• Limited Flexibility for Changing Demand: Product mix and lot-size variability, including lot size one, were difficult to support efficiently.
• Space-Use Pressure: QSC needed significantly higher output while making better use of available floor area.

The Solution

FloStor engineered a unified material handling architecture inside QSC’s 21,000 sq ft facility that replaced manual carting with synchronized automation. The new design linked receiving, kitting, subassembly, testing, final assembly, and packout into one continuous, controlled production flow.

The system supported QSC’s lean and just-in-time goals by combining automated parts delivery, conveyorized transport, and digital traceability to ensure the right components and instructions reached the right workstations at the right time.

Systems Used

• Double-Stacked Horizontal Carousels: High-density automated storage and retrieval near receiving handled over 2,000 small parts for faster putaway and picking.
• Assembly-Fed Carousel Loops: A continuous 65-foot carousel delivered required components directly to final assembly cells, minimizing operator travel.
• Multi-Tier Conveyor Transport: Integrated conveyor paths moved subassemblies and finished product between process stages without manual cart dependency.
• Barcode and RFID Traceability: Barcoded work orders and RFID-tagged totes and pallets enabled automatic unit identification, routing, and status visibility.
• MRP-Connected Carousel Control Software: Standalone control logic coordinated parts release and kit picking against production demand signals.

The Power of Integration in Action

FloStor’s integrator approach unified hardware, controls, and information flow so physical movement and digital work instructions stayed synchronized. Materials, subassemblies, and finished units were routed by system logic instead of manual guesswork.

This allowed QSC to preserve human decision-making at the point of work while automation handled repetitive transport and retrieval tasks, improving both productivity and operational control.

“All the key decisions we leave up to the people on the floor. You would pay far too much to get equipment to do what people do best: thinking and making informed decisions.” – John Andrews, Chief Operating Officer

The Results

QSC transformed from a fragmented manual push operation into a lean, demand-responsive manufacturing flow with significantly higher output and better inventory velocity. The redesigned system improved pace, reduced waste, and created a scalable foundation for growth.

By treating material flow as an integrated system rather than a collection of standalone tools, QSC gained measurable operational gains while improving day-to-day execution consistency.

“This system has allowed us to eliminate quite a bit of waste in how we handle materials. And that’s going to be a major benefit to us as we continue to grow.” – John Andrews, Chief Operating Officer

Why This Worked

This implementation worked because QSC and FloStor focused on end-to-end flow design, not isolated equipment upgrades. Material delivery, routing logic, and workstation execution were engineered as one coordinated process.

• System-Level Integration: Carousels, conveyors, and data capture tools were synchronized to remove manual handoff gaps and routing errors.
• Lean Pull-Oriented Execution: Demand-based part delivery reduced excess WIP and improved responsiveness to production changes.
• People Plus Automation: Automation absorbed repetitive transport work while operators focused on quality-critical assembly decisions.
• Built-In Scalability: The architecture supported high mix, variable lot sizes, and continued growth without destabilizing flow.
