A ribbon microphone, also known as a ribbon velocity microphone, is a type of microphone that uses a thin aluminum, duraluminum or nanofilm of electrically conductive ribbon placed between the poles of a magnet to produce a voltage by electromagnetic induction. Ribbon microphones are typically bidirectional, meaning that they pick up sounds ...
Ribbon microphones use a thin, usually corrugated metal ribbon suspended in a magnetic field. The ribbon is electrically connected to the microphone's output, and its vibration within the magnetic field generates the electrical signal. Ribbon microphones are similar to moving coil microphones in the sense that both produce sound by means of ...
Lip-ribbon microphones use baffles to create an acoustic labyrinth within the body of the microphone. [1] The microphone's bi-directional polar pattern controls interference; sound from the commentator reaches one side of the ribbon more than the other, whereas sounds from other sources contact both sides of the ribbon (at a difference in phase of 180°) and cancel out. [1]
Audio engineers experienced with the 77-DX can position the microphone at different angles to modify its frequency response. For example, with the microphone suspended, tilting it on the horizontal axis will cause the ribbon to sag slightly, resulting in a noticeable boost in the lower-midrange frequencies. [6]
Both ribbon and condenser microphones can be used for Blumlein-pair recording. A few types of stereo ribbon microphones (B & O, [1] Royer, [2] AEA [3]) have even been purpose-built for just this type of recording. Several types of stereo condenser microphones (Neumann, AKG, Schoeps, Nevaton BPT) have also offered a Blumlein arrangement as one ...
When you think about the best headphones, built-in microphones are probably low on the list of features that first come to mind. Instead, we usually focus on how our music sounds, if that battery ...
