What is Frequency Response?
Most of us know what frequency is; the high or low tones of sound. But some have asked what frequency response is and how it relates to transformers.

The Voltage Dilemma
Custom design a XPWR transformer with a number of outputs (secondaries) totaling 300VA. Let’s say one of the outputs is 6.3Vrms (all future comments will be rms Volts) at 5A. In addition, don’t let the temperature rise above 40 degrees Fahrenheit and keep the flux density well below saturation. Simple, right?

Design Overview
Transformers are the least understood of all electrical components. So, we thought we would give you some insight into the design.

Tri-Tone Generator
This little circuit is a 3 tone generator. Back in the late 1970's and 1980's EDCOR used this generator on the a number of input modules that were used in their modular power and mixer amplifier. This module would supply a tri-tone to the amplifier when a set of connection was complete. It was use security and notification across the background sound system.
