Ortofon 2M Black Premounted MM Moving Magnet Cartridge

The Ortofon 2M Black Premounted is a pre-mounted version of the 2M Black cartridge, already installed on an Ortofon SH-4 headshell. It retains the 2M Black's flagship qualities of high detail, transparency, and authentic reproduction, while greatly simplifying the installation process. It is especially suitable for turntables with S-shaped tonearms (SME bayonet mount), allowing users to easily enjoy a near-top-tier vinyl playback experience.

Product Information and Design Features

The 2M Black Premounted features the 2M Black cartridge pre-installed on the classic Ortofon SH-4 headshell, with a total weight of approximately 16.7g. The SH-4 headshell is lightweight and sturdy, and is equipped with a standard SME bayonet connector, allowing it to be directly inserted into most S-shaped tonearms. There is no need to manually adjust the mounting angle or tighten screws, making it truly plug-and-play.

The cartridge itself adopts the standard 2M series design, weighing approximately 7.2g. It features a stable structure and supports interchangeable styli, allowing for direct upgrade to the 2M Black LVB 250 in the future.

The core technologies of the 2M Black include:

• Nude Shibata Stylus: The stylus profile is highly polished, with a contact area much larger than typical elliptical or fine-line styli. This allows it to more precisely track high-frequency information in record grooves, significantly enhancing detail resolution and high-frequency extension.
• Split Pole Pins Technology: Combined with silver-plated OFC (Oxygen-Free Copper) coils and a Quad-coils system, this effectively reduces magnetic loss, resulting in a flatter frequency response and a more precise and clean sound.

These designs make the 2M Black significantly superior to the Bronze and Blue models in the same series in terms of detail reproduction, transparency, and soundstage performance.

Sound Performance

The sound signature of the 2M Black Premounted is highly precise, transparent, and layered. It clearly presents the most subtle details and dynamic changes in music. The midrange is expressive and engaging, with vocals being particularly natural and immersive; the treble is clear, lively, and airy; the bass is solid and controlled. The overall listening experience is neutral and clean, with a wide soundstage and precise imaging, making you feel as if the artists are performing right in your listening space.

Whether it's classical, jazz, vocals, or complexly arranged music, the 2M Black reproduces the details and emotions in recordings with extremely high resolution and realism.
