conventional balanced input stages: poor common
mode rejection in real-world applications. While
conventional input stages measure well in the lab
and perform well on paper, they fail to live up to
their CMRR specs when fed from even slightly
unbalanced source impedances — a common
situation in almost any pro sound environment.
This is because conventional stages have low
common-mode input impedance, which interacts
with imbalances in source impedance to unbalance
common-mode signals, making them indistin-
guishable from desired, balanced signals.
High CMRR: typ. 90 dB at 60 Hz
Extremely high common-mode input
impedance
Transformer-like performance in an IC
Excellent audio performance
Several gains: 0 dB, -3 dB, & -6 dB

Transformers, the patented InGenius input
stage uses
common-mode input impedance into the meg-
ohm range without the noise penalty from the
obvious solution of using high-valued resistors.
Like transformers, InGenius line receivers
maintain their high CMRR over a wide range of
source impedance imbalances — even when fed
from single-ended sources. But unlike trans-
formers, these wide bandwidth solid state de-
vices offer dc-coupling, low distortion, and
transparent sound in a small package at rea-
sonable cost.
