The Control Switcher will always apply power to pins 1 and 3 on its MIDI In jack.

The jumpers only connect or disconnect the "phantom power" pins on the MIDI Out jack.

Because you want to phantom power your Control Switcher via its MIDI Out, you will have to set the jumpers so they are on both pins of the header. (didn't you have a picture of this here before?... it showed the jumpers connected as they should be to allow for phantom power thru)

You can either use a cable that does not wire pins 1 and 3, cut pins 1 and 3 out of the cable, or ask the manufacturer of whatever other piece of gear you are connecting to the MIDI In on the Control Switcher if they use pins 1 and 3 for anything.

I hope that helps!

Phew! The madness stops! I thought I was losing my mind?!?! No worries though...I'm always thankful for all the help you guys provide on all your products. Plus, I don't always explain things the best

Yes, I had a photo on here. Maybe I removed it in all my madness, but I don't remember. I thought you removed it. ARGH!! There must be ghosts in this house....

Just double checking...so... if I send phantom power to the control switcher's 'midi out' port from my preamp, it WILL NOT continue to send that power out through the 'midi in' of the control switcher and back to the other midi devices earlier in my chain. Basically, I want it to accept the midi phantom power on the 'midi out', but ONLY have the control switcher use it. I don't want it going anywhere else. Does this make sense?!?! Do I have the jumper pins inside the unit OFF or ON?!?!

In a synopsis, I use a 7pin midi cable from my midi footcontroller on my pedalboard to a custom interface on the board. The cable carries phantom on pins 6&7. That 7 pin midi cable connects from the pedalboard interface to the front of an another interface located in the back of my top rack. On the rear of the interface, a 5 pin midi cable connects to a midi thru box which splits the signal and sends it to all of my midi devices in the rack. Addtionally, one of those midi cable plugs to an input on the back of the interface. It is now sent out through the front of the interface to a rack below through a 7 pin midi snake cable. Out of the back of the bottom interface, I connect a 5 pin midi cable to the midi in of my control switcher. The midi out of the CS connects to the preamp's midi input. That midi input can send phantom out on pins 1&2. Thus, I wired a special midi cable to connect the CS and preamp. On the preamp side, power is wired to pins 1&2. On the CS side, power is wired to pins 1&3. The preamp sends 11vac.

My concern is if that 11vac that is being supplied to the control switcher is going out of the 'midi in' port and back through my midi chain. This would be bad because it would be sending phantom on pins 1&3 to the previous items in my chain which could be bad news, right?

How are all the voodoo supplies grounded? Are they grounded to the enclosure chassis or just through the power plug?

I have a Voodo Pedal Power AC, PP2+ and Digital in my rig. I'm still in the troubleshooting phase...

P-1800 AR (voltage regulator) + Pedal Power AC = more buzzy PPAC
P-1800 PFR (power conditioner) + Pedal Power AC = very little buzz PPAC

Same goes for the PP2+.

I bought some shorter power chords off amazon.com to use for both devices. Is it possible that I bought the wrong type of power chord? They both power up fine.

I can't find my original power chords for both units to see if it makes a difference. Is there something specific I should look for with the power chord (e.g. 30 celsius, 14awg, etc).

The only thing I can think of is the way the units are designed to regulate power within them? Maybe it has something to do with the way power is fed to them from the voltage regulator, instead of the power conditioner.

Not unless you are running a tiny little amp.

At 120 volts, the PP2+ only supports 200 watts through the courtesy outlet. That's approximately 1.6 amps.

You can look up the wattage on your amp to see how much it draws. It is most likely it won't stay under 200 watts or 1.6 amps.

Just don't do it.

I have a very interesting and mind boggling issue. I have a PP2+ and a Pedal Power AC. I also have two products from Furman: a P-1800 PFR (power conditioner) and P-1800 AR (voltage regulator). When I plug the Voodoo supplies into the P-1800 PFR, they make virtually no noise. However, when I plug them into the P-1800 AR, they hum pretty bad.

I have taken both Furman products out of the rack and it hasn't made a difference. Then, I plugged them into different outlets in my house. Still no difference....quiet as a mouse on the power conditioner and humming like a bee on the voltage regulator.

I'm stumped....

Currently, I have the voltage regulator in a top rack and the power conditioner in the bottom rack. All of my effects units are in the top rack (on the regulator) and my preamp/poweramp are in the bottom rack (on the power conditioner). According to Furman, I need to have the power conditoner in-line from the wall first and plug the voltage regulator into that.....so....I need to be able to have the Voodoo units on the voltage regulator.

Any ideas? I'm thinking this one's a 'stumper' for the great John Clark!!!! (yes, that is a challenge!)

Thanks, John. I decided to feed it a regulated 12v using the first output set to away. I don't want any chance of hum.

The info was great to know too!

Awesome! Thank you!

So, switching outlet #5 away will produce 50ma of regulated power at 14.5 volts, correct?

I've read the manual and website specs and this is what I understand from reading them, but I want to make sure.

Additionally, if I switch switch #6 away, it will produce 12v at 200ma but it will be unregulated power. Right?

I have a Analogman Mini Chorus Pedal. It can take 9v-18v. What is the best outlet to use on the PP2+ to run this?

Here is what they say on their website (but I'm not entirely sure what it means):
"You can use the ACA (12V) output on PedalPower2 for any of our chorus pedals. Use the normal PP2 boss style connector cables when using our pedals at higher voltage. The Mono chorus pedals can handle up to 18V max. 15-16 volts is the optimal voltage. The pedalpower LINE6 output is about 16 volts, perfect for our mono chorus. But the LINE6 output is unregulated so it may cause some hum depending on your gain and other equipment"

So...do I flip the switch on outlet #5 to use it at 14.5v? Or, should I combine a couple of the 9v outlets and run it at 18v (I have two outlets available). Is either option acceptable and safe for my pedal?

Thanks!

Thank ya!
