Este un circuit de MUTING la pornire. La pornire, cand apare tensiunea +Vp, tranzistorii Q102, 3 si 4 sunt deschisi ( avand tensiune pozitiva in baza) si pun semnalul audio la masa. D101 redreseaza o alternanta a tens de alimentare si condensatorul C126 ( 22uF) se incarca prin rezistenta de 100K si cand tensiunea pe el ajunge la +5.8V deschide Q101 care blocheaza tranzistorii 102-4 si scoate din Muting circuitul.
