CMK 250

The CMK 250 mic cable is ideally suited to cover long distances without signal loss or hum noise effects. It is, for example, used to cover long distances between PA and mic or the currently active speakers during open-air events without any problems. The bulk cable features stranded bare CU wires and is easily reelable without twisting.
