Rf to A/V circuit
Department of conversion signal RFI To the Video and Audio
Description of Service
But if we want to add a special chamber to the TV that will turn the situation RF to the A / V There we have some older types of television there is no special channel for the development of A / V If the knees VCR or receiver often choose a channel on the UHF frequency and we deliver Place the antenna cable up to the RF output device that we want to link it to your TV
Explain the circuit
Never explain How to install the Service A / V
Tuner and phase-frequency interface and also know when diverge and follow the path of each other Totally independent from the other And when we decide to install Service A / V in a TV are heading to the stages
First we have to recognize the device that we will be installing the constituency for him and the stages Each of my reference picture and sound both stages such as the Joint Department
All died from my reference image and sound to each other and going to another effort to signal amplifier Daily Video by Lane and separate the first party from the Daily Line for Video Blaster After separation then becomes the first out mutually with us Blaster Video
And other income Daily Line and we take the signal from the amplifier to the visualization of the Department of A / V In the Party of No. 8 of the Integrated labeled V. AMP and we plug the labeled DL in the circle to the entrance of the Daily Lane and then go to the audio section after Reagent Volume Plans and whether to control the volume through manual key or electronic control A circuit that works by remote control and go to a section in the audio output Magnifier we entered this disconnect signal from the detector and give Reagent came out of the Party of No. 4 of the Department of the A / V
Labeled ATT.OUT and we plug the labeled S. OUT to income
Magnifier latest voice and then we need not only nutrition for the Department of the 12 Volts up to the party 14 of the integrated circuit and the ground is a party to No. 7 and then We take both the party labeled AUDEO.IN and we connect it to Jack
And make the jack in the back of the device and write underneath AUDEO IN
And we take the party labeled V IN and we plug it into another Jack and make it in the back of the device And write underneath VIDEO IN And back to the rest of the circuit party Vnachz labeled SW
And go to the Buttons choices channels and not the last and separate from this button, all relevant By the lines and keep the line of the 12 volts so that the 12 volts at the tip of the button, And get the other party by the party labeled SW so that if we pressed the button, the link 12 volts of the Party of the SW and as the party of the SW operating the transistor as a key Electronic, the arrival of volts across the resistance R5 No. Will make the transistor works and the complex voltage drops to zero and then change the path of the voltage From R4 to R6 and then switches you to work within the integrated TC4066
Is working to divert income from both my reference audio and image from TV mode to AV mode
Thus, we have completed installation of the Chamber
