Speaker Protection Circuit against DC voltage appearing at output 1. When an abnorma

40、l negative voltage appears at output TR601 turns off, TR602 turns on and TR603 turns off so that the relay, RL601, keeps off in order to protect loudspeakers from break-down. 2. While the relay, RL601, keeps OFF, zero voltage(center volt- age) controlling TR607 through D607 will increase, resultly t

41、he LED701 as protector indicator, starts flickering. 3. When abnormal positive voltage appears at output , the voltage is supplied to TR602 directly, and the operation of the protector circuit is same as above mentioned 1, B. Speaker Protection Circuit against abnormal over-current 1. At the moment

42、when abnormal excessive current flows into power transistors, a transistor (TR09) detecting ex- cessive over-current, on power stage becomes ON. 2. Then, DC voltage at decreases, resulfly TR604 turns on and positive certain voltage appears at 3. As mentioned above, when TR602 turns on, the relay, RL

43、601 keeps OFF; a certain positive voltage at turns on TR60S too, resultly collector voltage of TR60S decreases and its col- lector voltage keeps a certain voltage at simultaneously. 4. By keeping a certain DC voltage at ., the LED701 as pro. tector indicator continues flikering, even though all cir-

44、 cuits work completely. POWE R OUTPUT 0602 R06. lR6Ob -?B D05,06. 13. D603. 605, 606, 1i07 1524730 0.04 VOl212 ZD601 EQAOI 06R AU-517/717 0: 0: LE0701 a: ell 0: C. Operation of astable multivibrator 1. When control.(bias) voltage is not supplied to the base of TR607 in abnormal condition, TR606 and

45、TR607, on astable multivibrator repeat turning (switching) on and off alter- nately each other by charging and discharging of capacitors C606 & C607, resultly, the LED701 as protector indicator continues flikering. 2, When the relay, RL601 is turned on, base voltage of TR607 becomes zero volt through D607 and TR606 becomes ON resultly LED701 as power indicator lights up.
