Old versions of the EL-OP were unbalanced only. This version has both transformer (floating
!) balanced and unbalanced (transformerless) inputs. The outputs are similar offering
transformer (floating) balanced XLR and unbalanced 1/4 jacks. The output transformers are
"driven" either way so even using unbalanced outputs there may be a part of the "character"
caused by the iron. Recording engineers tend to prefer the sound of good transformers. If done
right, they saturate a little in the deep lows and this effect "warmth" is usually attributed to
"tubes". Its the tubes that give it that clean, immediate, musical quality. Transformers give
that rich, fat bottom end - its not a "boost" like EQ but more like a low frequency "exciter".
Analog magnetic tape also saturates this way as does the better vintage gear - tube or discrete.
