Global standard RF207 U band frequency agile modulator AV converter to RF converter

standard: PAL/DK PAL PAL NTSC M SECAM D / K BG I

This modulator (RF converter)
ALPS high quality PLL phase lock control box (ANT IN input interface built in signal amplifier circuit)
The EM78P153 microprocessor which controls the core of Taiwan instrument
Using 24C02 ATMEL memory (storage output frequency and sound mode)
The two digital display unit, display the current RF output frequency (corresponding channel)
The stability of the switching power supply (for AC voltage 90~240V) and other related components.
Features: phase locked control, frequency stability, built-in modulator all metal shell shield, with good shielding and cooling effect. The RF output frequency is 471.25MHZ~855.25MHZ continuously adjustable (each channel interval bandwidth is 8M), working in the UHF band, and the output of VHF is: the work of this band is influenced by frequency, which can guarantee the circuit most of this kind of product market and reliable quality of the RF output signal on the discrete components are however, our products are of high quality of the finished product box with modulation (Samsung, ALPS and other specific production batches), and are using special IC modulation (Motorola). So it can achieve good image restoration, no distortion. With audio and video direct input no difference. The modulator circuit has been widely used in digital video recorders (DVR)

Main function:
The AV converter can be set-top boxes, DVD players, satellite receivers, audio and video game consoles (AV) signal into radio frequency (RF) signal. The original audio and video (AV) input signal through the antenna input socket of TV, watching the same television programs.
Function:
If you purchase a VCD, DVD, digital set-top boxes, game consoles and other audio equipment, your original TV without audio, video (AV) input, unable to watch digital TV, DVD, gaming machine. Using the AV- frequency converter, you can see any original type TV digital TV VCD, DVD. Play games!
Usage method:
The AV jack on the back of the converter is connected with the digital set-top box, DVD/VCD, or AV output hole on the game machine
The back of the converter output (RF TO TV) RF input jack plug wire with TV connection, (ANT IN) at the same time with jack cable TV signal connecting jack, watching television or audio and video signal source can freely switch.
Turn on the power behind the machine
The open DVD/VCD, into the disc, or open the game, enter the working state
The open TV search in the UHF band, until the search to the satisfaction of the image and sound.
The side + local identity as the output frequency adjustment button, adjustable output frequency, if the cable signal output frequency with the local conflicts caused by interference, can use this button to adjust the output frequency after re search, can be solved once and for all. The fixed frequency outputs, if encounter this kind of situation, only through the input signal from time to time to and fro plug cable to solve (signal input, TV must unplug RF converter directly inserted into the TV signal cable).
RF converter interface specification:
Audio and video input socket 1 yellow, red and white three colors (AV socket), used to connect the DVD/VCD set-top box, or game on AV socket
2 RF input jack (ANT IN), is used to connect the public cable television network
3 RF output jack (TO TV), used to convert the AV signal into a radio frequency signal, the output to the TV (connected to the TV's RF RF input port).
