Phonos duo is thus even more versatile. Whether moving magnet (MM) or moving coil (MC) cartridge systems – the SPL VOLTAiR technology and the RIAA filter in the legendary Douglas-Self design form the fundament for an outstanding phono sound.\u003c\/h2\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eVisually, the SPL Phonos duo Phono Preamplifier fits perfectly into the SPL HiFi line \u003c\/span\u003e\u003cspan\u003eProfessional Fidelity – and is of course available in the three basic colors black, red or silver.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThere are two pickup systems for record players: Moving Magnet (MM) and Moving Coil (MC).\u003c\/p\u003e\n\u003cp\u003eMoving magnet cartridges generate a voltage by moving a magnet between copper coils. In order to achieve the best possible linearity of the frequency and phase response, the capacitance is modified to adjust the cartridge. Phonos duo offers six different capacities for this adjustment: 12 pF, 47 pF, 100 pF, 150 pF, 220 pF und 330pF.\u003c\/p\u003e\n\u003cp\u003eThe moving coil cartridge is also a small electromagnetic generator. However, the magnets are firmly anchored – and the coils move between the magnets. This concept is exactly the opposite of the moving magnet cartridge. Consequently, it is not the capacitance but the impedance that is the decisive parameter in matching the cartridge.\u003c\/p\u003e\n\u003cp\u003ePhonos duo offers six different impedances for this adjustment: 20 ohms, 50 ohms, 100 ohms , 220 ohms, 500 ohms and 1 kohm.\u003c\/p\u003e\n\u003cdiv class=\"elementor-element elementor-element-ba407b0 elementor-widget elementor-widget-heading is-mac\" data-id=\"ba407b0\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\"\u003e\n\u003cdiv class=\"elementor-widget-container\"\u003e\n\u003cp class=\"elementor-heading-title elementor-size-default\"\u003e\u003cstrong\u003eMC or MM ?\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementor-element elementor-element-ba387c2 elementor-widget elementor-widget-text-editor is-mac\" data-id=\"ba387c2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\"\u003e\n\u003cdiv class=\"elementor-widget-container\"\u003e\n\u003cp\u003e\u003cstrong\u003eMoving coil cartridge\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003esystems are commonly regarded as the more audiophile systems, as they allow a faster and therefore a finer cartridge due to their low mass. They bring out the finest nuances of the record. The output voltage of a moving coil cartridge system is extremely low at just a few hundred microvolts and is therefore more sensitive to noise and induced hum.\u003c\/p\u003e\n\u003cp\u003eThe very low output voltage makes preamplifier design a challenge, because it has to be pre-amplified extremely noise-free. With up to 70 dB preamplification, Phonos duo offers one of the most powerful phono preamplifiers for moving coil systems. Thanks to SPL 120V technology, Phonos duo amplifies extremely low-noise, linear and phase-locked.\u003c\/p\u003e\n\u003cp\u003eMoving coil cartridges have a very low inductance and impedance.\u003c\/p\u003e\n\u003cp\u003eThis means that the effects of cable capacitance (from the cartridge to the preamplifier) are not that significant. The impedance, however, is the relevant parameter here and can be set in six positions on the Phonos duo. The manufacturers specify the impedances of the cartridges. These should be followed as closely as possible.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"elementor-element elementor-element-6bb598a elementor-widget elementor-widget-text-editor is-mac\" data-id=\"6bb598a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\"\u003e\n\u003cdiv class=\"elementor-widget-container\"\u003e\n\u003cp\u003e\u003cstrong\u003eMoving magnet cartridges\u003c\/strong\u003e, on the other hand, are more rugged and often less expensive. The greater mass of the moving magnets causes more inertia, which results in less precise reading of the record. However, modern moving magnet systems also use neodymium magnets, which have a significantly lower mass. Such moving magnet systems can also keep up with some moving coil systems in terms of accuracy.\u003c\/p\u003e\n\u003cp\u003eCapacitance plays a significant role with moving magnet cartridges. This means that the effects of cable capacitance (from the cartridge to the preamplifier) can‘t be ignored here.

This is ideal in combination with standard HiFi devices that operate with a reference level of -10 dBV In switch position “Med”, the amplification is increased by 10 dB (MM = +40 dB, MC = +60 dB). If the switch is in the “High” position, the gain is increased by a further 10 dB (MM = +50 dB, MC = +70 dB).
