Default Is it possible to configure IVY for 4 Vrms output for balanced and 2 Vrms for SE?

I use the IVY III with a Buffalo II directly into active monitors. I just upgraded, and my new monitors need more output than 2 Vrms to work properly. I ordered the resistors to change to 4 Vrms from the manual. I sometimes use the single ended outputs for my headphone amplifier, and I am wondering if there is a recommended way to keep the single ended outputs at 2 Vrms and change the balanced output to 4 Vrms.

Is there a way to transparently add a switch to change from 2 Vrms output to 4 Vrms output on the IVY III?

Thank you for taking the time to read my post.

Aaron.

Default Maybe wrong question: Does IVY III SE output stay at 2 Vrms when bal is 4 Vrms?

I looked in the manual and it wasn't clear, and I realized that I might have asked the wrong question.

Does the single ended output of the IVY III stay at 2 Vrms when the balanced is increased to 4 Vrms by changing R13-16 to 356ohms?

Thank you for your time.
Aaron.

Hi,

Balanced is usually double single ended if the same circuitry does both.
If the circuitry is separate changing one won't affect the other.

You tell me, you have the manual .

rgds, sreten.

If you want 2VMRS from SE in this case you will want to use 1K or 1.15K(which ever is easier for you to source) at R21-R24. The high value will get you higher output.

Cheers!
Russ

Thanks for the reply. I'll probably change the resistors next time I order for a project, even though it seems to be working with my headphone amplifier with the higher output.
