Mundorf Resistor 3R9 Ohm 20W M-Resist Series
With our MResist SUPREME you can enjoy even finest details and spatial information which normally get lost. Due to the complex bifilar structure from 1Ω with two wires being wound around the high-temperature-resistant cement element simultaneously the inductance is always below 75μF.
In addition, the MResist SUPREME series features acoustic neutrality and music reproduction close to reality. This is due to a special manually applied fire-resistant casting compound which optimally fixes and stabilises the resistor winding thus protecting it against microphony effects.
In order to maintain high sound quality even at high load, we apply a special copper-nickel alloy as conducting material featuring a positive and extremely low temperature coefficient of only 50ppm/°C.
Further details which guarantee that MResist SUPREME resistors are hardly noticeable anymore are the of use non-magnetic materials and welded contacts.
