i'm hoping someone will help me out to understand the difference (if there is a difference) when using an older SD mixpre which has outputs that are impedance balanced, vs. an newer mixpre that has active balanced outputs when using it as a front end to feed signal into ch 3/4 of a 744T.
i've got a few other questions:
are there differences in quality, level, rf/interference rejection or other?
is active-balanced and balanced the same thing?
when going through an xlr how does impedance balanced avoid interference by having only one voltage line when compared to balanced that has 2
