I have bought a TC Helicon voice Tone R1 reverb unit. It has Phantom power built in. When I use my Shure SM 86 in Channel 1 on the L1 unit, do I have the L1 phantom power switch on or off?
thanks, Tony

Hi TonyMC,

If you have microphone that required phantom power (your SM86 does) then you turn on the phantom power on the device to which the microphone is directly connected.

So
If the microphone is connected to the TC Helicon device, that is where you turn on the phantom power.

If the microphone is connected to the T1®, that is where turn on the phantom power.

Did I answer your question?

So, if the mic. is plugged into the tc helicon which has phantom power, then the lead from it is plugged into the L1 where the phantom power turned off, correct?
Thanks.

Hi TonyMc,

Correct. In the scenario you describe below, you should not need to have phantom power turned on, on the T1®.

I've wondered about the phantom button as well. What if you do leave it on when it is not needed? Could that damage the T1?

Hi Wayne,

Never say never, but I cannot imagine a scenario where you could damage the T1® by leaving the Phantom Power turned on. As long as you are using properly wired microphones (or devices that use phantom power) you should be fine.

Having said that, if none of the things connected to the T1® require phantom power, I just turn it off.

I just scanned through the T1 ToneMatch® Audio Engine Owner's Guide
and did not see any warnings.

I was just worried about having the phantom power on the reverb unit and also switched on, on the L1 at the same time. I don't know if this would damage anything.
Tony.
