When muting, MUTE1, MUTE2 and MUTE3 outputted by CS4360 all change into high level. At this

time, for the base electrode of Q211 is high level, Q211 is cutoff and Q212 is also cutoff. The emitter

electrode of Q213 changes into high level and also is on. +9V voltage is added to MUTE-1 through

Emitter-Collector of Q213, the outputted high level is added to the base electrode of switching tube

Q205~Q210. The switching tube is on and sound is bypassed to ground.

Power-off quieting: when working normally, because there is no forward bias, Q214 is in cutoff state.

When powering off, +9V disappears and the base electrode of Q214 changes into low level. For

capacitor TC235 discharge is high level to the emitter electrode, Q214 is on. The discharge of TC235

makes MUTE-1 outputs high level and add to each switching tube through Emitter-Collector of Q214 to

make the switching tube on and sound is bypassed to ground to realize the function of power-off quieting.

Power-on quieting: when powering on, VCC is connected to power supply, voltage of the two ends of

Tc238 cannot change suddenly. The base electrode of Q211 changes into about 5V and then Q211 is

cutoff, Q212 is cutoff and MUTE-1 changes into about 1.68 to perform power-on quieting function.

The function of -9V voltage in the figure is to ensure the secure cutoff of each switching tube when

circuit is working normally.

3.2.12 Card read circuit

MT1389HD is with card read and USB read function. For model DV725SI, it cancels card read

function on the basis of DV725S, so the socket XS207 on decode board is cancelled and USB socket

XS205 is added. Here we mainly introduce principle of USB, shown in the figure 3.2.12.1, when machine

is switching USB state, insert USB, decode board +5V supplies power for USB, USB begins to work.

Through USBPO USBMO data bus, data is transmitted to pin 47, 28 of decode chip for decompression

to reconvert into audio and video signal required to play by us. Card read function is similar to that of

USB read. A detect switch on card holder is used to recognise the type of card inserted. Card read

adopts the means to connect with decode chip directly and process inside decode chip.
