Ideal for connecting an oscilloscpe directly to the balanced outputs of a tape recorder for checking the azimuth of the record and replay heads. The XLR connectors are made by Neutrik. The cable is designed for digital data rates of upto 3Mb/s, so will have no effect on "low frequency" analogue audio signals. The BNC connectors are professional grade. No more messing around with fiddly 'scope probes and crocodile clips!
