Suggested testing for Audio AT Editor Schematic - For Audio. The AT Editor schematic here represents the transformer. Measurements of Insertion Loss (ILOS) and Longitudinal balance (LBAL) require source resistors and load resistors to be fitted to the transformer to simulate the impedance of the transmission lines, so that it can be tested under “real world” conditions.

An audio transformer refers to a small transformer that is used in the signal path of a piece of audio equipment for various purposes. You can increase or decrease signal strength with step up/down transformers. These transformers have differing impedances between windings. If the windings are of the same impedance, then they are referred to as ...
