Ortofon MC A Mono, patefono galvutė
Jei paleidžiate MONO įrašą su stereofonine kasete, abiejuose kanaluose nepasieksite to paties signalo dėl tokių netobulumų, kaip antai perskyros, triukšmas, fazės klaidos, sekimo klaida, antiskatingas ir iškraipymai. Dėl šio skirtumo tarp kanalų vaizdas bus nestabilus ir iš dalies neryškus. Monofoninis jungiklis tam tikru mastu gali tai pagerinti.

The Ortofon Exclusives series of our highest-performing Moving Coil cartridges has now been expanded to include the brand new MC A MONO cartridge
The MC A Mono is a TRUE MONO cartridge for play-back of MONO recordings.
If you play a MONO record with a stereo cartridge you will not achieve the same signal in the two channels due to imperfections such as crosstalk, noise, phase errors, tracking error, antiskating and distortion. This difference between the channels will result in an unstable and partially fuzzy image. A mono switch, to some extent, can improve this.
Playing MONO record with a TRUE MONO cartridge will have none of the aforementioned problems, as this cartridge only produces one signal, which afterwards is directed to both channels in the system. This will provide a much more forceful and stable image with a fuller sound.
Another significant advantage of using a TRUE MONO cartridge to play MONO records is the absence of response to vertical movement. This means that a TRUE MONO cartridge is essentially impervious to the pinching effect which comes into action when the stylus is pushed vertically upward in very narrow grooves. In addition, the response to dust, dirt and wear will be reduced substantially as the vertical component will not be heard. The final result will be a much more clean and noiseless reproduction of the MONO record. These effects simply cannot be achieved merely by the use of a mono switch.
