... Description of Operation 1. Signal route The CXA2559Q signal circuit is shown in Fig FWD RVS PBFB 2. Gain adjustment method Adjust the playback equalizer amplifier gain so that –6dBm is output on LINEOUT (Pins 7 and 24) by playing back the reference tape for Dolby level adjustment. By this adjustment, the output can be the same level as for the CXA2560Q and CXA2561Q which have the built-in Dolby NR system ...

... Playback equalizer amplifier The CXA2559Q 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 ...
