They are one in the same. It is an AF equalizer that integrates into the AF audio chain like any other equalizer.

I would like a short explanation of just exactly what function the Receive and Transmit Equalizers in pSDR perform. The Users' Manual simply states that they are "there" and how to set them, with no explanation of what they do. In common lingo, an equalizer tailors the shape of the passband of an audio channel, much the same as the "treble" and "bass" controls do on an ordinary radio. I am used to the "equalizer boards" found in music recording applications, and my naive assumption was that these controls in pSDR control the same sort of functions on the receive and transmit audio. Is this correct? I have complaints that my audio is "bassy." [F3K, USB, 6 meters] The microphone is a Heil HM-5 and the mike gain is set so that voice peaks show around 0 dB on the meter. If my interpretation is correct, this could be taken care of with the "transmit equalizer," cutting the bass and boosting the mid-range and treble ends. Again, I need some reassurance that my understanding of the word "equalizer" in pSDR is the same as the common usage. Some guidance about amount of boost and attenuation would be useful. Thanks...
