"Until now, there hasn’t been an ideal cable available for stereo tube microphones. The cables were either too stiff, too thick, too prone to pick up ambient noise, or simply not robust enough for daily studio use. The Octave Tube Stereo has finally provided a solution that performs this task perfectly, both electrically and mechanically. The technical support and communication with Sommer cable on this matter were outstanding.”

Peter Drefahl
Service technician for vintage studio microphones

The cable that truly understands the character of tube microphones ...

The new SC-Octave Tube Stereo Microphone Cable from Sommer cable has been specially developed for stereo tube microphones. It combines eight wires within a robust jacket. The four audio cables for the stereo pair each consist of 72 super-fine wires and ensure linear transmission with exceptional flexibility. These are complemented by two control lines, one for the anode and one for the heating voltage. This means the cable also meets the complex demands of modern studio environments.

Full screen comprising spiral copper braiding and aluminium fleece reliably protects the signals from electromagnetic interference. The robust PVC jacket, with a diameter of 6.5 mm, ensures high durability and simple use, even with frequent use on stage or in the studio.

We stomp on it...with our SC-Octave Tube which has been custom-designed for the connection of tube microphones or remote-controlled studio microphones. It has a total of 7 conductors, two for the supply voltage and the others for parameter-variable directivity, sensor (measuring) line, heating, and the voltage supply for the tube capsule. These five conductors consist of 72 superfine 0,05 mm single wires and guarantee a linear transmission and high flexibility.Owing to its 100 % coverage shielding (helical copper mesh screen + AL fleece) the SC-Octave Tube is perfectly protected against all kinds of interference.It is ideal for connecting Neumann, BPM, or Schoeps microphones.Advantages:Audio and power signal in one cable100 % interference protectionHigh-quality, linear transmissionHighly flexibleApplication:Connection of tube microphonesAlso usable as a high-quality control line
