Built-Like-A-Tank™ construction. Type: Phantom Power Supplies. Phantom Voltage or "induced voltage" is the result of wire or other metal components appearing to be energized when they in fact are not. How this works is that when you have ungrounded wiring, like Knob & Tube wiring or older ungrounded romex-type wiring in your home and you add metallic pathways (wires and conduit) to these old circuits the metal wires and/or conduit will pick up an induced voltage merely by being in proximity to the hot conductor in the circuit. If this happens, a re-ribbon servicing will be required to restore the mic to new working order. electronic loads may have problems The term phantom power is a throwback to the development process that condenser mics have gone through since they were first invented. A Note Regarding All Phantom Powered Microphones. This method can be used for networks with four-wire or eight-wire cabling. What is “Phantom Usage”? Is that the total voltage from both inputs or the voltage on each input individually? to check it, try powering a light bulb with it, chances are, the bulb would not light.

Phantom power is normally supplied by the microphone mixer, but may also be supplied by a separate phantom power supply. Spare-pair power feed Spare pair power feeds utilize wire pairs that are not otherwise used, the voltage being One reason not to do it (a choice some interfaces make) may be that designing a step-up converter in a manner where it doesn't interfere with high-sensitivity audio circuitry in the same enclosure is non-trivial. So there is no voltage between pins 2 and 3. #This means that the actual voltage that gets to the mic can be a lot less than you might expect. That way even if some phantom power is applied, the load will be enough to prevent the 3.3V supply rail from rising high enough to cause trouble, because the phantom power can’t (presumably) supply more than a couple of milliamps at most. Make it burn. 48V uses 6.81K, 24V with 1.2K and 12V uses 680 Ohm. A keyed variation of the usual XLR connector, the XLD connector, may be used to prevent accidental interchange of analog and digital devices.

Phantom power uses the same wires of the mic balanced output signal to carry that energy from the mixer console to the microphone. Usually, this is on the order of 1 to 5 watts, which means that it would take 200 to 1,000 hours for a single device to even use a single kilowatt hour, which costs $0.10. So this means that there is a lot of voltage dropped across the 6.81k phantom power resistors. The most common phantom power supplies will typically supply voltage within the range of 12 to 48 volts and will be present on a balanced 3-pin XLR connector. Therefore, the power supply voltage, protection diode and TVS specifications have to combine for a successful implementation [5]. While this may be true, most condenser microphones will operate on 9 to 12 VDC of phantom power. The supplied voltage is usually between 12 and 48 Volts, with 48V being the most common. If the voltage exists, then any phantom powered microphone will work fine. If there's a voltage difference, you'll have the same problem. The Mic came with an XLR to 3.5 mm cable, and the phantom power supply comes with its own M-F XLR cable so the connection would be like Mic to the phantom in using the supplied cable with the phantom; then, phantom out to PC line in with an XLR to 3.5mm cable that came with the mic. Phantom circuit.
