The Kirmuss Audio KA-RC-1 is a patented ultrasonic vinyl record restoration system developed by Charles Kirmuss after 12 years of research into record manufacturing and vinyl storage[cite: 1]. Unlike conventional record cleaners that only perform surface maintenance, the KA-RC-1 executes a multi-cycle restoration process designed to strip away sticky PVC mold release agents ("pressing oil"), fungus, and micro-welded dust from deep within the groove walls[cite: 1].

Operating with a patented 35 kHz cavitation system generating 70 kHz passive resonance, the KA-RC-1 utilizes a 6-liter tank with a specialized floating suspension mechanism that processes up to four records simultaneously without mechanical skewers or label contact[cite: 1]. By pairing high-velocity 500 MPH (805 KPH) cavitation plasma waves with the proprietary KA-AS-1 ionizing surfactant, the system neutralizes vinyl surface charges to lift contaminants, restoring the stylus pathway for a guaranteed 1.3 to 4+ dB gain over the noise floor and a 20–30% increase in frequency response and harmonic clarity[cite: 1].

KEY FEATURES & PROPRIETARY TECHNOLOGIES

• True Groove Restoration Process: Strips away manufacturing mold release agents (silicic acid/pressing oil), fingerprints, fungus, and past cleaning residues to let the stylus sit at the base of the groove pocket[cite: 1].
• Patented 35 kHz Cavitation with 70 kHz Passive Resonance: Utilizes a record-safe 35 kHz ultrasonic frequency generating 500 MPH (805 KPH) plasma waves to blast away micro-welded groove debris without damaging PVC[cite: 1].
• Standing Wave Prevention Architecture: Limits bath capacity to a maximum of 4 records in a 6-liter tank to maintain critical disc-to-disc spacing and prevent standing wave cancellation[cite: 1].
• Charge-Neutralizing Ionization Surfactant (KA-AS-1): Applied via a specialized goat-hair brush to temporarily invert the record's natural negative charge to positive, actively pulling cavitation plasma waves deep into the grooves[cite: 1].
• Patented Floating Suspension System: Records float safely in the tank without mechanical skewers, clamps, or risk of wet or damaged center labels; accommodates any record size and speed[cite: 1].
• Visual Confirmation & Water-Repellent Finish: Contaminants are visibly extracted as a white "toothpaste-like" paste; records emerge virtually dry as pure restored PVC naturally repels water without vacuum or forced air drying[cite: 1].
• Proven Acoustic Improvements: Delivers a measurable 1.3 to 4+ dB noise floor reduction alongside 20% to 30% greater high-frequency detail, tonal realism, and harmonic decay[cite: 1].
