I think i am slowly getting my head around this, Paul can you please confirm if the following are true or false,
-With 4 & 8 ohms the windings are in Parallel, 16 & 32 ohms the windings are in series.
-When wired in parallel the center tap is devised via resistors from each winding, and when wired in Series the center tap is the link between both windings.
-When in unbalanced mode the output transformer negative rail is tied to chassis ground so GND and NEG become the same, and the center tap devised above is left floating.
-When in balanced mode the center tap devised above is connected to ground, and the transformer negative rail becomes the NEG tap for balanced operation.
-With an XLR jack, if the switch is set to unbalanced mode its going to function no different from a regular unbalanced TRS jack as the negative points become grounds.
-With a TRS jack, if the switch is set to balanced mode its only going to be connected to half of the output transformer as the ground rail is connected to the output transformer center tap, not the negative rail?
Now i just need to figure out what the optimum configuration is for headphone only use in balanced and unbalanced modes. i.e Balanced with 300ohm load (XLR), and unbalanced with 32ohm loads (TRS).
-I've read the lower the ohm setting the lower the noise floor.
-I assume 16 & 32 ohm mode is preferable for balanced operation due to the real center tap vs the resistor devised center?
-Manual recommends 32ohm setting for headphone only use, would love to know the reasoning for that?
Thanks again for your patience, i have almost finished this build and will promise to stop bugging you guys
