5 ASSISTING YOUR SMOOTH QSO RX DSP EQUALIZER RX DSP Equalizer allows you to change the desired sound quality by adjusting the frequency characteristics of the received audio. The desired sound quality can be selected from six types of RX DSP Equalizer profiles for the main band and sub band independently. The custom made equalizer characteristics can be configured for User 1 to User 3. Bass Boost 1 Bass Boost 2 Flat Low-pass frequency components are emphasized. This configuration is effective for audio that contains high-pass frequency components. Low-pass frequency components are emphasized. This configuration provides characteristics that further emphasize the lowpassband, compared with Bass Boost 1. The flat characteristics SWITCHING THE RX DSP EQUALIZER ON OR OFF Each time you press [RXEQ/SEL], you toggle the RX DSP Equalizer between active and inactive. User 1 User 2 User 3 You can save your preferred frequency characteristics as User 1, User 2 and User 3. The default characteristic is "Flat". 10 5 0 -5 -10 -15 -20 -25 -30100 101 102 103 3FDFJWF

This configuration is effective for audio that contains low-pass frequency components. High-pass frequency components are emphasized. This configuration provides characteristics that halve the low-pass attenuation level of High Boost 1. This configuration attenuates frequency components outside the audio band, thus providing legible characteristics. Customizing the Equalizer You can customize the equalizer characteristics to your desired characteristics. Also, such customized characteristics can be stored as the User Configuration. 1 Press and hold [RXEQ/SEL] to open the RX Equalizer screen. 2 Select the target equalizer to be adjusted. 3 Press [ADJ] (F4) to open the RX Equalizer Adjustment screen. 5-6 Index Contents
