12THEORY OF OPERATIONOverviewThe Lifestyle® Model 5 music center is a self-contained CD player, AM/FM tuner, preamplifier,and control center for use w
13THEORY OF OPERATIONThere is one main serial data bus that controls source selection IC U101, volume control ICU103, PLL frequency synthesizer U302,
14THEORY OF OPERATIONU103’s output signal is buffered by U105, and is fed to the A and B outputs. These outputs areindependently mutable through trans
15THEORY OF OPERATIONThe E and F signals are amplified and subtracted. This produces the tracking error signalTEAO (U501, pin 7 ). The F channel’s gai
16THEORY OF OPERATIONU505’s oscillator is obtained from a 4MHz ceramic resonator (X502). U505 is reset by a risingedge on pin 1 that is caused by R573
17THEORY OF OPERATIONoscillator tuned circuit. The tuned output appears on pin 12 and is fed to AM buffer FET Q300.The buffered output is sent to U301
