![]() This output stage emulates a transformer such that it can providethe noise rejection capabilities of a balanced connection even over asingle-ended line. Output Circuit - The improved output circuit features LM4562non-inverting buffers to provide a low noise, high impedance input.These are capable of feeding the very low impedances required to makethe low noise differential floating output stage based on 4x OPA1602ICs. They allow the converters in the DEQ to reach their full potential with significantly lower distortion and noise of all kinds. Theseupgrade circuits are available as a self-install kit or withinstallation provided by BehringerMods. The solution is to replace the analog sectionsin their entirety with new circuit designs from BehringerMods. Infact, the DAC and ADC chips inside the DEQ are high-end items from AKM.The distortion is created by the analog buffer circuits, not theconverters themselves. The features of DEQ mentioned above are superb, however there is an achilles heel the analog inputs and outputs have relatively high distortion compared to the best alternatives.
