Figure 2 The Block-Diagram of MPX Driving Circuit
It is to be desired that CR time constant circuits are provided at NR OFF/B/C terminal and PB/REC/MPX
terminal with time constant from 0.1 sec to 1 sec. If so, it will reduce the switching click noise effectively.
Application Circuits
1. HA12161FP/62FP application
HA12161FP/62FP are developed for exclusive playback of car stereo players.
But these devices are provided with AUX input. This application providing AUX input is available for
car stereo players and car stereo cassette decks.
AUX input will be useful for a tuner input. In this case PB/REC/MPX switching operates as the
switching of PB/AUX1/AUX2.
