Why is my phantom power not working?

Most phantom-power problems are caused by faulty cables, which you can identify either with a cable tester or by swapping out the cable for another that you know to be OK.

What PIN does phantom power travel on?

The DC phantom power is transmitted simultaneously on both pin 2 and 3, with the shield (pin 1) being the ground. Since the DC voltage on the ‘hot’ and ‘cold’ pins (2 & 3) is identical, it is seen by equipment as “common mode” noise and rejected, or ignored, by the equipment.

How do I know if phantom power is working?

First, measure the phantom power voltage:

• Disconnect the mic cable from the mixer.
• Set the Volt/Ohm/Amp meter to read from 0 to 50 volts DC.
• Measure from XLR pin 2 to XLR pin 1.
• Measure from XLR pin 3 to XLR pin 1.
• Measure from pin 2 to pin 3.

Why is my studio microphone not working?

Try the following solutions: If your headset has a Mute button, make sure it isn’t active. Make sure that your microphone or headset is connected correctly to your computer. Make sure that your microphone or headset is the system default recording device.

Do I turn on phantom power first?

You should refer to the specs of your microphone to be sure it is safe to turn on phantom power before plugging any microphone into an input with phantom power. Never plug line instruments into the XLR input jacks with phantom power engaged.

Do I need phantom power if I have an audio interface?

If you connect a ribbon mic to your audio interface, you actually need to ensure that phantom power is off, or risk damage to the microphone. Dynamic mics usually won’t be damaged, but they do not need phantom power. If you are using an instrument’s output, definitely avoid using phantom power.

How do you check phantom power?

First, measure the phantom power voltage:

1. Disconnect the mic cable from the mixer.
2. Set the Volt/Ohm/Amp meter to read from 0 to 50 volts DC.
3. Measure from XLR pin 2 to XLR pin 1.
4. Measure from XLR pin 3 to XLR pin 1.
5. Measure from pin 2 to pin 3.
