Other Functions

The RX DSP equalizer (RX EQ) allows you to easily adjust frequency characteristics of the RX/TX audio. From various

preset equalizer curves, you can select your preferred setting and adjust it.

Likewise, the TX audio characteristics can be adjusted with the TX DSP equalizer (TX EQ). With this, you can correct the

microphone characteristics and also correct it to follow characteristics of your voice.

The volume of each band divided into 18 bands can be adjusted in the TX Equalizer Adjustment screen and RX

Equalizer Adjustment screen. The screens also allow the preset equalizer curves to be customized and the unique

equalizer curves to be configured. The equalizer settings for the TS‑590S can be customized only using the ARCP‑590

PC software; however, the TS‑990S enables customization of the equalizer settings on the TX Equalizer Adjustment

and RX Equalizer Adjustment screens. Use of this function extends wider varieties of equalizing settings.

Typical audio graphic equalizers divide a spectrum by octave. The equalizers in the TS‑990S are designed to divide

a spectrum in multiples of 300 Hz. This enables notches to be inserted to a specific frequency and the results of

complicated frequency analysis to be reproduced. The settings configured in the TX Equalizer Adjustment screen

and RX Equalizer Adjustment screen are immediately applied, and finer adjustment is applicable while monitoring the

audio.

Customized equalizer settings can be stored in a USB flash drive. Preferred audio characteristics settings can easily be

diverted and applied to the TS‑990S from the USB flash drive.

Unlike conventional transceivers, which require an optional voice guide and storage unit, the TS‑990S has a voice

guidance function in a DSP to make the voice guidance and playback functions available.

The new voice guidance speed control function does not change the pitch of the guiding voice even if the speaking

speed is increased; hence, it provides more natural speech speed control.
