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.

Features
An improved engine, which provides a high level of sonic accuracy
Spherical diamond that is perfect for playback of 78 rpm shellac records, which require a larger stylus profile
