It would be great to make a passive mixing console with just summing transformers (hybrid transformers) made with Magnetec's nanocrystalinne tape wound toroidal cores.
The best way to add signals with minimum loss is with spliter transformers connected the other way round.
Signal 1 is connected to upper side of primary winding. Signal 2 is connected to lower side of primary, Center tap of primary is connected through canceling resistor to ground. Signal (1+2) is received from secondary in all its pristine glory.
This is how Hollywood did it and more information can be found in earlier euroelectron posts. Many signals can be combined to one.
