Hey all,
Been searching for an answer to this. Let’s say we use a transformer with multiple “1” secondaries, and we send those to different loads? What gets reflected back to the primary? Simply the lowest loaded secondary’s impedance?
Case example.. in the context of a mixing console, I’m considering putting something like a Carnhill VTB 2280 / 2281 at the end of a line channel, before the passive summing resistor network. Then one secondary could continue to feed the mixing path, and the other extra secondary could provide a direct output of said channel/preamp. And if I were to discover an affordable transformer that offered even more, like a 1:1:1:1, the extra third secondary could feed an Aux bus.
Direct out would see 10k-15k of an audio interface, where as both the aux pathway and mix pathway would each see a 22k summing resistor amongst others that feed into a 12AY7 grid.
What happens to the primary impedance and to the transformer performance overall?
