The high-end studio-microphone cable CSM FM Gold 250 comes with all the relevant features for demanding voice recordings.

The bulk cable CMK 250 with a particularly large copper diameter of 0.5 mm² results in an extremely low attenuation, which is a decisive criterium for the brilliance of the transmitted signal. Highly pure copper (OFC) is used. This too is vital for pure, unadulterated sound.

The gold contacts of the NEUTRIK XLR male and XLR female plugs that are fitted within the CSM FM Gold 250 reduce the risk of corrosion to a minimum.

The cables have transparent shrink sleeves for individual marking. An additional cable hook-and-loop fastening makes sure that the cable wraps up neatly.

The cables – with available lengths of 2.5 m / 5 m / 7.5 m, and 10 m (additional custom lengths are available on request) – effortlessly bridge any distance within the studio.
