AFI FLAT.DUO

Preservation and Process Control

The AFI FLAT.DUO is a German-designed and manufactured system for the controlled treatment of vinyl and shellac records. It combines precisely regulated thermal energy, calibrated contact pressure and stabilized active cooling to ensure repeatable, material-safe results.

FLAT.DUO operates in three dedicated modes:

Relaxing (thermal tempering) for the reduction of internal stresses within vinyl

Flattening for the correction of measurable record warpage

Shellac mode with specifically adapted temperature parameters for fragile materials

Temperature gradients are tightly controlled to prevent material shock. Fixed pressure rings mounted to aluminum heating plates apply defined, torque-controlled contact pressure, ensuring uniform heat transfer across the record surface. A managed cooling phase stabilizes the material before removal, reducing the risk of reintroduced stress.

Dual-disc operation enables two records to be processed simultaneously within the same cycle. In combination with active cooling, this significantly increases operational efficiency while maintaining identical thermal and pressure conditions for both discs.

Audiophile Application: Relaxing as Material Optimization

In high-performance analogue playback systems, residual internal stress within vinyl can influence groove stability and stylus behavior. Even records that appear visually flat may exhibit micro-deformation or tension resulting from pressing, storage or environmental exposure.

The relaxing mode functions as a controlled tempering process. By applying low, precisely regulated heat over a defined time sequence, the vinyl polymer structure is allowed to rebalance and settle into a more uniform mechanical state. The subsequent stabilized cooling phase preserves this equilibrium.

For discerning listeners, the result is not tonal alteration but improved mechanical consistency:

• More stable stylus contact
• Reduced micro-resonance within the groove wall
• Improved low-level retrieval
• Greater clarity and transient precision
• Relaxing is therefore a refinement process aligned with high-resolution analogue replay systems.

Retail Application: Controlled Flattening for Used Inventory

For second-hand record retailers and professional resellers, the flattening mode provides measurable commercial benefit.

Visible warpage can compromise tracking, increase stylus wear and negatively influence customer perception. FLAT.DUO applies calibrated heat and defined pressure to safely re-level warped discs while preserving groove integrity.

Dual-disc capability supports efficient batch preparation, and active cooling reduces overall cycle time. Records can be treated prior to grading or sale, improving presentation quality and playability. This contributes to reduced returns, increased buyer confidence and consistent retail standards.

The system is designed for repeatable operation in professional environments where both performance and reliability are required.
