Can voltage fluctuations in the phantom power (PP) cause microphone hiss?
It's very unlikely that voltage fluctuations in the phantom power (PP) could cause hiss.
What are the 3 pins for phantom power?
There are three pins. Phantom power is connected to both pin 2 and pin 3 (but as long as your cable is not broken, simply use it).
X stands for ground (it is connected to the cable shield).
Pin 1 (X) = ground
Pin 2 (L) = + most commonly, or Left
Pin 3 (R) = - most commonly, or Right
Will phantom power damage dynamic microphones?
The risk is higher if it is an unbalanced connection. The Sound Reinforcement Handbook by Yamaha says something like this:
"In a phantom power system, the polarizing supply voltage is placed on both of the signal lines in a balanced connection, with the same polarity on each line. Dynamic microphones connected in a balanced system with a phantom power input are then protected from damage, theoretically, since the system results in a net zero DC potential across the coil. However, a dynamic mic connected unbalanced to a phantom power input may be destroyed."
In other words if you take a sm57 and plug it into a phantom powered mic pre using a normal balanced mic cable then you should be safe.
If you take an unbalanced mic and wire it with a xlr plug so you can connect it to that same input then you could fry the mic. In a balanced connection the 48 volts is running parallel down the 2 signal wires. With an unbalanced connection (2 conductors) you have 1 signal wire and ground and doing this is basically completing a circuit that sends 48volts directly to the mics voice coil.
What are the correct steps connecting a mic to phantom power
So the steps when connecting are:
1. Turn down those master faders.
2. Plug in mic.
3. Turn Phantom Power on.
and when disconnecting:
1. Turn down those master faders.
2. Turn Phantom Power off.
3. Unplug mic.
Big Signal Hit from AKG 414 on Avalon 2022 from Phantom 48
Forums
Hello people, I am wondering from sometime now why when I turn on or off the phantom power on my Avalon 2022 for my AKG 414 BXL II it gives 2 or 3 signal hits for over +3 dbs, an then settles. They work great together, but always behaves the same manner after turning on/off its phantom +48 power. Is this normal, sometimes in the powering of the +48 signal says hello this way?.

Sweet'n Phantom Image/Delay Lines For Panning
Forums
Regarding Vocals, but also pertaining to other instruments.
I was reading the book Total Recording, by Dave Moulton, and he speaks of sweet'ning the phantom image using delay lines.(Center/Lead vocal with a floating image(so to speak)). As well as panning, using delay, instead of the pan function.
Is there a Phantom Power "canceller"?
Forums
So I'm just a little curious if anyone knows of a device, like a DI or something that acts as a safe guard against Phantom Power? For use with Ribbons basically. I ask because its like a recurring nightmare of mine to just slip on the phantom power button, and then "boom".

Portable Phantom Power
Forums
Hi,
Does anyone have a design for a phantom supply (48vdc), that is battery or wall supply powered? I would like to get the output as close as possible to 48vdc at 2-10ma. I understand this could be done with an appropriate voltage doubler circuit. Any info would help. Thanks much!

Phantom Power Question?
Forums
Might be a stupid question...
When using a condensor mic, should I turn my preamp to the "Mic" setting and then turn on the +48v or:
Turn on the +48v then switch the preamp to the "Mic" setting.
Would doing it the wrong way damage a mic? Thanx all! -matty

Phantom Power Supply
Hello everyone, I am looking for a good, highly regulated, phantom power supply.
My Emu 1820M's phantom power supply is jacked up, FOR THE SECOND TIME. Bought the Emu, 7 months later, PREAMP PROBLEMS, I got a new on on warranty, 8 months later, same thing. Exact same problem. Now Im out of warranty, and the 1820M is discontinued. The Card is great, but damn them preamps.
