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 ...
This results in a 12-volt potential difference with significant current capability across pins 2 and 3, which would likely cause permanent damage if applied to a dynamic or ribbon microphone. Plug-in-power (PiP) is the low-current 3–5 V supply provided at the microphone jack of some consumer equipment, such as portable recorders and computer ...
An electret microphone is a microphone whose diaphragm forms a capacitor (historically-termed a condenser) that incorporates an electret. The electret's permanent electric dipole provides a constant charge Q on the capacitor.
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 ...
Most microphones used in sound reinforcement are either dynamic or condenser microphones. One type of directional microphone, called cardioid mics, are widely used in live sound, because they reduce pickup from the side and rear, helping to avoid unwanted feedback from the stage monitor system .
Microphone diaphragms, unlike speaker diaphragms, tend to be thin and flexible, since they need to absorb as much sound as possible. In a condenser microphone, the diaphragm is placed in front of a plate and is charged. [2] In a dynamic microphone, the diaphragm is glued to a magnetic coil, similar to the one in a dynamic loudspeaker.
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]
