I am feeding an audio signal into the primary of an 8 ohm to 1K ohm microphone coupling transformer. The secondary is split, having a center tap.
I would connect the center tap directly to earth so I can pull inverted signals off the active legs and have each drive a small resistive load to earth. In other words, they would be anti-phase with respect to each other.
I do not want to overload the signal source, which is a 10W amplifier, so I was planning to connect a 12 ohm ceramic resistor at the common point between the two loads and earth.
Is this a proper set up, or should I also float the center tap of the transformer above earth?
