Frequencies between 200 and 320 Hz have a certain attenuation that mitigates the QRM. From 320 Hz onwards, sensitivity stays around 83 dB up to 1.2 KHz. Then, it rises to 88 dB between 2
and 2.8 KHz.
In the bass sounds region the curve has an important emphasis between 120 and 200 Hz. This feature offers the option to enjoy very solid bass sounds, both to AM listening and to opening the SSB filter with wider signals.
Between 3.1 KHz and 18 KHz, Miranda offers a fairly flat curve that ensures good sound for broadcast signals.
