Audio Technica ATOC9
The AT-OC9 incorporates a powerful samarium cobalt magnet in the magnetic circuit.
The greater magnetic density between NS yoke poles improves the electrical generation.
The pure copper by Ohno continuous casting process has revolutionised transparent transmission and has raised to a high level of efficiency and accuracy of the transmission.
Frequency response: 15 to 50,000 Hz
Output voltage: 0.4mV
Channel separation: 30dB / 31dB (ML II)
Output balance: 1.0dB
Vertical tracking force: 1.25 to 1.75g (standard 1.5g)
Stylus: special elliptical / MicroLine (ML II)
Neutral through the midrange, the OC9 is less sweet and three-dimensional than, for example, the vdH MC One, but not by much. Highly recommended (and an excellent tracker).
