Ortofon 2M 78 Premounted, turntable head

The 2M 78 has an improved motor that ensures high audio fidelity. The sensor has a spherical diamond tip which is perfect for 78 rpm. for restoring shellac plates that require a larger sensor profile.

• Frequency range: 20-20.000 Hz + 3 / - 1 dB.
• Stylus type: Spherical.
• Recommended tracking force 1.6-2.0g (16-20 mN)
• Tracking angle - 20°.

The 2M 78 features an improved engine , which provides a high level of sonic accuracy. The stylus' tip is a Spherical diamond that is perfect for playback of 78 rpm shellac records , which require a larger stylus profile. The cartridge body is manufactured from Hopelex, which ensures high rigidity while eliminating unwanted resonances.

2M 78 uses a strapped output to deliver the same output signal from both sets of pole pins. This effectively eliminates the need for mono-specific equipment, making it possible to enjoy true mono reproduction on any stereo playback system.

The 2M Series provides excellent compatibility when used in an assortment of playback systems and with a wide variety of phono preamps.
