Glossary
| Audio output level (balanced) |
| Logarithmic value of the audio output voltage based on a standard reference value. A balanced circuit or connection uses separate signal lines for sending a signal, returning the signal and ground (3-pole connection). |
| Audio output level (unbalanced) |
| Logarithmic value of the audio output voltage based on a standard reference value. An unbalanced circuit or connection uses the ground connection (or screening) to return the signal (2-pole connection). |
| Frequency response |
| The frequency response of a microphone is given within the limits defined by the manufacturer. In studio condenser microphones it is generally within the range of between 20 Hz and 20 kHz. |
| Operating time |
| States how long a unit can be continuously used with one set of batteries / rechargeable accupack. |
| Pick-up pattern |
| Also known as polar pattern, directivity. According to their acoustic design, microphones differ in their sensitivity towards sound from different directions. Pressure microphones have a sensitivity that is largely independent of direction (omni-directional pick-up pattern). Pressure gradient microphones have the pick-up patterns wide cardioid, cardioid, super-cardioid or figure-of-eight. Interference microphones can be used to achieve a further concentration of the pick-up pattern (lobar pick-up pattern). As a special case, dummy head microphones achieve the pick-up pattern of the human ear/head (dummy head stereo). |
| Power supply |
| Description of the power source used for powering a unit, for example mains, battery, rechargeable accupack, etc. |
| Power supply (handheld transmitter) |
| Description of the power source used for powering a unit, for example mains, battery, rechargeable accupack, etc. |
| RF frequency range |
| The range of frequencies to which a unit (e.g. a receiver) can be tuned. |
| RF output power |
| Output power measured at the antenna socket. |
| Switching bandwidth |
| The frequency band in which frequencies can be switched directly. |
| Transducer principle |
| Two transducer principles have become established for the conversion of electric energy into mechanical energy: electrodynamic and electrostatic transducers, whereby the latter is only to be found in audiophile systems, due to their relatively high manufacturing costs. Electrodynamic transducers basically consist of a ring-shaped permanent magnet and an oscillation coil, which is fixed to the receiver diaphragm. When an audio-frequency alternating current is passed through the oscillation coil, it is caused to vibrate in accordance with the audio-frequency alternating current, thus causing the diaphragm to vibrate in the same way. |
