A NOTE ON DISTORTION The human hearing system is a remarkably complex mechanism and we seem to be learning more details about its workings all the time. For example, Oohashi demonstrated that arbitrarily filtering out ultrasonic information that is generally considered above our hearing range had a measurable effect on listener’s electroencephalo-grams.

of annoying feedback. 5045 FEATURES THE LINE OUTPUTS The main output signal comes from the output transformer secondary which is balanced and ground free. A ground free connection guarantees freedom from hum and radio frequency interference when connected to a balanced destination such as the input to a mixer. However, the transformer may be used with one leg grounded without any change in performance. It is not necessary to “ground” one leg at the Portico output.
