Ortofon MC A Mono

Ortofon MC A Mono – Exclusive True Mono Moving Coil Cartridge

The Ortofon MC A Mono is a flagship dedication to mono vinyl playback, crafted to extract the fullest musical potential from monophonic recordings. With cutting-edge materials and a precision mono-only design, this cartridge offers unmatched tracking stability, clarity, and depth for audiophiles building a serious mono system.

Why a True Mono Cartridge Matters

Stereo cartridges reproduce mono records imperfectly, often resulting in channel imbalance, tracking errors, and vertical groove noise. The MC A Mono eliminates these issues entirely—it reads only horizontal groove modulations and outputs a single high-fidelity signal folded perfectly into both channels. The result? A rock-solid stereo image, reduced surface noise, and vibrant musical presence on mono records 

Premium Engineering & Materials

SLM Titanium Body: Built by Selective Laser Melting, this one-piece titanium chassis offers exceptional internal damping and mechanical integrity—ensuring resonance-free playback and compatibility across high-end tonearms 

Wide Range Damping (WRD) & FSE: Incorporates a platinum disc sandwiched between rubber dampers, plus Ortofon’s Field Stabilizing Element in the magnet circuit—resulting in smoother response, reduced distortion, and improved channel separation 

Stylus & Generator Technology

Nude Replicant 100 Diamond on Boron Cantilever: This ultra-fine stylus profile, matched to the original cutting stylus, delivers exceptionally accurate groove tracking, supreme detail, and extended frequency performance 

Aucurum-Style Gold-Plated OCF Copper Coils & Metallic Armature: Featuring Ortofon’s high-purity coil wire and precision armature, this generator design minimizes internal impedance (7 Ω) and maximizes channel clarity 

Performance Highlights

Output Voltage: 0.2 mV at 5 cm/s—optimized for MC preamps and step-up transformers. 

Frequency Response: 20–20,000 Hz (+2/–1 dB)—accurate across the audible spectrum. 

Tracking Ability: 90 µm at 315 Hz—ensures stable playback even near the record’s inner grooves. 

Compliance: 13 µm/mN lateral—compatible with most medium to high-mass tonearms. 

Stylus Tip Radius: r/R 5/100 µm—ultra-precise tracking with minimal distortion. 

Tracking Force: 2.3 g (range 2.0–2.5 g)—balances fidelity and record integrity. 

Weight: 6 g—ideal for modern tonearms. 

Real-World Praise

Reddit users frequently emphasize the sonic clarity of mono setups, with one noting that a mono cartridge “focuses the sound really well and makes all my old records sing” . Another shared that a true mono cartridge “absolutely silent” on older mono records, with “dust and pops virtually eliminated” 

The Verdict

If your vinyl passion includes mono classics—from vintage jazz to early rock & roll—the Ortofon MC A Mono is a game-changer. Engineered with elite materials and precision tooling, it delivers unmatched purity, resolution, and musical immersion. For dedicated mono collectors and analog enthusiasts, this cartridge stands alone as a pinnacle of mono playback engineering.
