NF2CB2 Profi phono Technical Details:
Precision made all metal design cable mount phono plugs with spring loaded ground contact combining a retractible element with separate wedge contacts which keeps the shell in the front position when engaged thus making ground before signal contact and breaking signal before ground providing a direct and strictly coaxial electrical connection from the socket via the shell to the cable shield. Sold in display packed pairs only with each pack containing one black and one red identified plug. Two sizes of cable chuck are also supplied in each pack for cables of 3.0 – 5.5mm and 5.5 – 7.3mm in diameter.
