4 DSP
Figure 4-20 shows how the waveform changes when the speech processor is toggled between active
and inactive.
You can see that when the speech processor is activated, the differences in amplitude are averaged
and the talk power is increased.
The speech processor has two settings: HARD and SOFT.
HARD is a setting that you choose so as to increase talk power while tolerating some distortion and
SOFT is a setting to minimize rasping distorted audio. Select either of the two settings according to
your predilection and operational circumstances.
4.8 DSP-based Auxiliary Circuits (Common to TX/RX)
4.8.1 TX Equalizer & RX Equalizer (AF Processing)
If you use the RX equalizer (RX EQ), you can easily adjust RX audio quality. Pick your quality of
choice from the preset curves: high boost, formant pass, bass boost, and flat.
Likewise, TX audio quality can be adjusted with the TX equalizer (TX EQ). It is easy to make
changes to suit your taste of TX audio quality: for example, correcting microphone characteristics or
applying compensation to match the characteristics of your own voice.
Also, on the TS-590S, with the ARCP-590 provided on the Kenwood Web page, you can adjust the
settings in the 18-band graphic equalizer offered in its Audio Equalizer window (Figure 4-21). This
function offers you more diverse options for equalizing.
Any adjustments made in the Audio Equalizer window of ARCP-590 are reflected in the TS-590S in
real-time. Meanwhile, the equalization done while "User" is selected is stored on the TS-590S.
Typical graphic equalizers used in audio devices divide the spectrum into octave segments. In
contrast, the equalizer on the TS-590S divides the spectrum into multiples of 300 Hz to allow the
insertion of a notch at a particular frequency and precise reproduction of complex frequency analysis
results.
