Ortofon 2M 78 True Mono - MM pickup

Danska Ortofon har utökat sin otroligt populära och storsäljande 2M-serie med två modeller. Nu har man tänkt på de som sitter med gamla stenkakor hemma (2M 78) eller för optimal återgivning av monograverade vinylskivor (2M Mono). 2M 78 har en förbättrad motorstruktur kallad ´True Mono´, som bidrar till en exaktare ljudåtergivningen. Även den speciella slipningen av den 65μm sfäriska diamantnålen är som klippt och skuren för 78 varvs plattor, som kräver en större profil av nålen. 2M 78 använder en fast utsignal från båda polstiften. Detta eliminerar behovet av mono-specifik utrustning, vilket gör det möjligt att njuta av äkta mono-återgivning på alla stereosystem. Ortofons produktinfo: - 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 - 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. 2M 78 Technical data Output voltage at 1000 Hz, 5cm/sec. - 4 mV Channel balance at 1 kHz - Channel separation at 1 kHz - Channel separation at 15 kHz - Frequency range at - 3dB - 20-20.000 Hz Frequency response - 20-20.000 Hz + 3 / - 1 dB Tracking ability at 315Hz at recommended tracking force - 70 µm Compliance, dynamic, lateral - 18 µm/mN Stylus type - Spherical Stylus tip radius - R 65 µm Tracking force range - 1,6-2,0g (16-20 mN) Tracking force, recommended - 1,8 g (18 mN) Internal impedance, DC resistance - 700 Ohm Internal inductance - 350 mH Recommended load resistance - 47 kOhm Recommended load capacitance - 150-300 pF Tracking angle - 20° Cartridge colour, body/stylus - Black/Grey Cartridge weight without screws - 7,2 g 2M PnP MkII cartridge with integrated headshell weight - 20 g 2M PnP MkII cartridge with integrated headshell length - 52 mm Replacement stylus unit - 2M 78 (interchangeable with 2M Mono) Stylus lifetime: with proper care we find that up to 1000 hours is possible without degradation of performance.

The 2M Series' engines, coils and magnets configurations are not identical: Red and Blue are identical, so are the Bronze and Black and so are the true mono variants 2M Mono and 2M 78. Likewise, 2M series styli are interchangeable within the below combinations: - 2M Red, 2M Blue and 2M Silver - 2M Bronze and 2M Black - 2M Mono and 2M 78
