PROFESSIONAL RECORDING STUDIOS
ATR Service is widely recognized for producing the most meticulous and accurate restorations of the Ampex ATR-100 Series recorders. Our rebuilds exceed the construction standards, precision, and performance consistency that were achievable during original factory production, while preserving the unmistakable sonic character that made the ATR-102 the reference mastering machine for decades.
Precision Engineering with Respect for the Original Sound
We take great care never to alter the inherent sonic qualities of the ATR-102—the clarity, openness, and stability that engineers and artists depend on. Instead, we focus on elevating the machine’s mechanical integrity, electrical stability, and long-term reliability through:
• Improved build quality using modern precision components
• Enhanced grounding and stability architecture
• Updated reliability modifications that address well-known failure points in original units
• Modern calibration and verification tools that ensure exact performance from machine to machine
The result is an ATR-102 that delivers the classic Ampex sound with greater consistency, accuracy, and operational confidence than ever before.
Built for Demanding Professional Workflows
For mixing, mastering, or print-to-tape workflows, studios require a recorder that is stable, predictable, and sonically transparent. ATR Service rebuilds provide:
• Exceptional wow & flutter performance
• Precise channel matching and level accuracy
• Low noise and stable electronics
• Smooth, reliable tape handling for long sessions
Each machine is calibrated and tested using modern metrology and Audio Precision measurement tools to ensure true mastering-grade performance.
The Modern Standard for the ATR-102
Professional studios around the world rely on ATR Service machines because they combine the unmatched sound of the ATR-102 with contemporary engineering refinement and long-term support. Our goal is to give studios a recorder that not only honors the Ampex legacy but performs at a level that original production models rarely achieved.
