An external phantom power supply. Phantom powering consists of a phantom circuit where direct current is applied equally through the two signal lines of a balanced audio connector (in modern equipment, both pins 2 and 3 of an XLR connector). The supply voltage is referenced to the ground pin of the connector (pin 1 of an XLR), which normally is ...
Phantom power is usually supplied at a nominal 48 volts DC, although lower voltages are permissible and modern microphones will often operate over a wide range. It is common for modern mixers to have a built-in switch-operated 48-volt power supply which supplies all mic inputs with phantom power, thus eliminating the need for bulky external ...
Neumann U 87 with shock mount. Introduced in 1967 as the solid-state successor to the U 67, [4] [5] [1] Neumann introduced the U 87 alongside the KM 86, KM 84, and KM 83 as part of the company's first 'FET 80' series of microphones that utilized use solid-state FET electronics that didn't require separate power supplies or multi-pin power cables and allowed the mics to be made smaller. [6]
In 1966 Neumann adapted the "phantom powering" method that had been used for years in certain telephone systems, so that a compatible method of powering would allow tube microphones, solid-state microphones and dynamic microphones all to be connected to the same power supplies.
In addition to providing gain for the microphone signal, a microphone preamplifier as found in a sound mixer or as a discrete component typically also provides power to the microphone in the form of either 24 or 48 volt phantom power.
Since the 1980s, phantom power has become much more common, because the same input may be used for both powered and unpowered microphones. In consumer electronics such as DSLRs and camcorders, "plug-in power" is more common, for microphones using a 3.5 mm phone plug connector. Phantom, T-power and plug-in power are described in international ...
