So I bought a minidsp 2x4 hd dsp processor and was toying briefly with the idea to use this for Pa system tuning, equalization, crossover duty etc.

Problem is the outputs are unbalanced.
I have a couple of edcor wsm 10k:600 and also 600:10k transformers lying around doing nothing, would these work? Im thinking 4.1:1 stepdown from foh mixer xlr outputs into the dsp and then 1:4.1 stepup on the outputs, or will the impedance reflected to the minidsp output stage be to low when connected to your average pro amplifier balanced line input for it to drive the output correctly?
The specs for the minidsp are as follows:
Analog audio input Unbalanced stereo (2 channels) analog audio on RCA connectors
- Max input of 4V or 2V RMS, jumper–selectable
- Input impedance: 10kΩ
- THD+N: 0.003% (RCA to USB)
- Dynamic range: 103dB
Analog audio outputs Unbalanced analog audio (4 channels) on RCA connectors
- Max output: 2V RMS
- Output impedance: 560Ω
- THD+N: 0.001% (USB to RCA)
- Dynamic range: 103dB
Im mainly asking since i already have these transformers lying around if it would work ok. If not, maybe point me in the right direction. I could always build something with drv134/drv135 or opamps aswell I guess. Thanks for any advice!
