Abstract:
A transformer saturation compensation circuit for loudspeakers in embodiments of the invention may include one or more of the following features: (a) a transformer with a primary winding and a secondary winding electrically coupled to an output, (b) a high pass filter, (c) a current dependent resistive load electrically coupled in parallel with the capacitor and electrically coupled to an input, (d) a switch located at the primary winding electrically coupled to the capacitor and the resistive load, the switch being rotatable to each of the taps, where the current dependent resistive load provides saturation compensation for different loudspeaker configurations without requiring changes to a highpass filter cutoff frequency, and (e) a resistive load electrically coupled in parallel with the current dependent resistive load and the capacitor.
