using Mic level TX4M and rX4M isolated modules

These modules are typically employed when splitting a mic signal 

between two mixers. Although the transformers may be ordered inside 

either the transmit TX4M or receive RX4M boxes, these are usually put 

inside the transmit box as this affords greater flexibility.

For instance, you may be doing a gig where your stage mics need to be 

sent to a monitor mixer by the stage, as well as a distant front-of-house 

mixing console. The TX4M would allow you to directly connect your 

microphones to the FOH console so it can provide phantom power, while 

high-performance Eclipse transformers keep the monitor mixer isolated 

and prevent ground loops.  

You can also use the same TX4M module to isolate the microphones 

to feed a separate recording system. Transformers are truly amazing 

devices that surprisingly come in handy in all types of situations.
