Glossary
| Input voltage range |
| Indicates the voltage range of the input signal within which a unit will work properly, i.e. as specified in its technical data. |
| Modulation |
| The process in which one wave is varied by some parameter of another wave, for example, an RF carrier frequency that is modulated by an audio signal. Types of modulation include amplitude modulation, frequency modulation, pulse code modulation and pulse width modulation. |
| Number of channels |
| Frequencies which are available to transmit a signal. |
| Operating temperature |
| Gives the range of temperatures at which a unit can be operated without damage. |
| Phantom powering |
| Almost all studio microphones are supplied with 48V ±4V phantom power (P48, IEC 268-15). This supply voltage is applied to both modulation lines, while the return current flows via the cable screen. Some microphones can also be powered by batteries or from plug-in mains adapters. |
| Range |
| See RF wireless headphones, transmission loss. |
| 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. |
