How Does Microphone Phantom Power Work?

Posted by Metro DC Music on

Phantom power, as the term is used with audio equipment, is DC voltage transmitted through microphone cables to operate microphones that contain active electronic circuitry.  It is most commonly used with condenser microphones and active direct boxes.  Phantom power supplies are often built into mixing consoles, microphone preamplifiers and similar equipment. In addition to powering the circuitry of a microphone, traditional condenser microphones also use phantom power for polarizing the microphone's transducer element. Continuing from our prior post on microphones with a video from the EEVBlog and Doug Ford, the former head designer at Rode Microphones, they now move on to how microphone phantom...

How to Coil Cables and Why Coiling Around Your Arm is Wrong

Posted by Metro DC Music on

From our Best of YouTube video series we like this one from the London School of Sound on how to coil cables properly.  The London School of Sound is a non-profit independent organisation dedicated to teaching professional sound and music production. The video shows two ways to coil a cable, but before we get to that, you may be asking "why is it wrong to coil a cable around your arm?"   There are really two answers to this.  The first is that when we're done coiling the cable we want it to hang in a nice coil that can be easily...
