THAT1200

The THAT 1200 series of InGenius balanced line receivers THAT1200 are designed to overcome a serious
limitation of conventional balanced input stages - notoriously poor common mode rejection in
real world applications. While conventional input stages may exhibit good rejection characteristics
in the lab and on paper, they perform poorly when fed from even slightly unbalanced source
impedances - a common situation in almost any pro sound environment.

Developed by Bill Whitlock of Jensen Trans- formers, the patented InGenius input stage uses a
unique bootstrap circuit to raise its common- mode input impedance into the megohm range,
but without the noise penalty that comes from high-valued resistors. InGenius line receivers
maintain their high CMRR over a wide range of source impedance imbalances - even when fed
from single-ended sources.
