... Playback equalizer amplifier The CXA2560Q configures the playback equalizer amplifier by connecting the external capacitor C1 and resistor R1 shown in Fig. 3. Two systems (FORWARD and REVERSE) of playback head input are provided for each channel. The FORWARD input pin is selected when DRSW (Pin 19) is Low; REVERSE is selected when DRSW is High. The playback equalizer amplifier frequency response can be set in two levels (70µ ...
