Phantom power?

[Nailpicker]

X-----1st device needing Pp------2nd device needing Pp-----guitar(or condenser mic needing Pp)

If X provides needed Phantom power to the 1st device, will that Phantom power continue down the line to the 2nd device as well? If so, how many Pp devices might be chained off that one device (X) providing the Pp?

This should probably be moved to the recording subforum, but how would you even do that? You usually plug them into a mixer where each input/output has their own power.

No...at least I've never seen a device that accepts, needs and uses phantom power and then exports phantom power for another device to use.

I didn't know where to post this. This is not about recording so I didn't put it there. However I have no problem if Mods want to move it. Sometimes it's not so clear where the best place to post might be.

X could be a guitar amp that provides Pp with a variety of pedals or devices that require Pp in the chain between amp and guitar, as just one example I'm thinking of.

There are pedals that use Phantom Power? I thought it was just mics that use that?

Can you please be more specific? (What exactly are you trying to do?)

There are some devices (not a lot) that are able to pass thru phantom power, I'm thinking about a particular Sound Devices (the brand) preamp that is phantom powered *and* provide power to a condenser mic plugged in it.
Also some DI boxes do that.

Now I'm afraid we don't understand what you want to achieve.

Phantom power needs a 3 conductors wire, so a balanced line, to work.
I don't know of many pedals using balanced signal (maybe the output, but not the input)

Amps don't provide power to pedals. To power pedals you have 3 options:
Internal batteries (not all pedals give you this option)
Wall warts
A power supply (a Voodoo Lab Mondo, for example)

However, none of those things is considered phantom power.

Some do. My LR Baggs Para DI does as one example.

Does it have Phantom Power out so you can connect them in series like described in the OP?

No, it does not. I'm not aware of one that does that. As someone else mentioned earlier, phantom power comes from the balanced XLR connection from the mixer (the line out from the DI pedal). The input to the DI from which which you are hoping to pass the phantom power is a 1/4 instrument cable connection doesn't have the three connectors (unbalanced).

If you want to run multiple pedals, your best bet is a multiple outlet pedal power supply.

Also be aware that there are different Phantom Power levels.
Older PA system run 15 volts.
Newer systems are 48 volt.

Don't experiment with this as you can cause damage to your equipment!!!

Good point. Know what the pedal needs.

I dont consider DI boxes and acoustic/mic preamps to be pedals. Pedals are effects like distortion, chorus, flange, etc and none of those run on phantom power. Most require 9vdc. Anything that provides phantom power will run off 110vac.

There are USB-powered audio interfaces that provide phantom power.
