6.6 Adjustment of TX Audio Quality

Similar to the received, the TX audio sound input from the microphone is also processed by
the DSP, thus enabling adjustment using the TX Equalizer.
6.6.1 TX Equalizer
The audio frequency band of the TX Equalizer is divided into four (4) different bands, each of
which can be adjusted within the range of -9 dB to +3 dB.
Users can choose whether to apply the properties of the preset equalizer to analog FM,
digital (D-STAR) or both.
