Technical Guide to Rane Analog I/O Stages*

UNB = Unbalanced Input or Output Stage = Single op amp design
SD = Simple Difference Input Stage = Standard single op amp difference design
BD = Buffered Difference Input Stage = Two op amp difference design
SI = Simple Instrumentation Input Stage = Standard three op amp instrumentation design
BB = Buffered Balanced
BAL = Balanced Output Stage = Standard two op amp line driver stage
X-X = Cross-coupled transformer-like output stage using: 1. Analog Devices SSM 2142 or 2. Discrete design
