Mixing Phantom with Non-Phantom

Posted on

The mixer board we just got doesn't have individual phantom switchability on each channel, only an all-or-nothing switch. I know it's possible to turn the phantom off and get a mic preamp for the mics we need to use phantom on, but that can become an expensive proposition. Is there any way to do the opposite, i.e. turn the phantom on but attenuate the jacks for the NON-powered mics? I saw a post where someone simply used an XLR to TRS converter and used the LINE jack, but will I still get a balanced signal that way?

The phantom powering does not act as a preamp; it just gives condenser mics the power they need to operate. The dynamic mics plugged into the mixer are self-powered, and will not be affected by the 48 volts, but you should remember to turn off the phantom powering or the mixer before plugging them in or unplugging them.
