Universal Composite Video Audio To RF Coax Agile Modulator
This RF/coax agile modulator converts and combines standard composite video/audio inputs to a modulated RF/coax output on a user-defined NTSC or PAL TV channel. 

All standard A/V signals from devices such as satellite receivers, Digital TV converter box, DVD player or security surveillance camera can be modulated and inserted to the existing or new cable TV system as one of your new TV channels. Its programmable channel selection permits users to assign a proper TV channel for the coax output from this coax A/V modulator.

Channel selection is easily done by convenient front panel button and channel entry will be stored in nonvolatile memory of this A/V agile modulator. Agility allows maximum flexibility in altering system channel line-ups and instant fixed channel replacement.

This composite video to coax modulator device offers performance, flexibility and reliability to meet the most demanding requirements and is very suitable for professional A/V installers as well as end users to build a private and centralized home TV or commercial TV distribution system customized for their own applications.

Multiple modulators can be cascaded in real time for broadcasting more A/V source signals and building up a large scale broadcast TV system for home use or commercial use for class rooms, hotels, restaurant, conference rooms, retail stores, hospitals and so on for easy multimedia content broadcasting.

Easy Operation
This RF modulator is very easy to be installed. Simply connect the video and audio output from device such as CCTV security camera, DVD or other media player to the composite RCA input of this agile modulator and then connect the coax output of this unit to your local coax TV system. Next use the push buttons and digital screen display located on the front panel to choose an unused or unwanted TV channel number in the range between CH58 and CH138 for NTSC TV or between CH21 and CH69 for PAL TV.

Lastly use your TV remote control to tune to the channel you just assigned for your DVD or camera video. Bingo !

Easy Integration
Through this audio/video coax modulator, users can simply use the existing coax cable system to transmit and control the new media content from the remote location. Simply using the TV's remote control to tune to specific cable TV channel for the desired media content to be displayed on any TV wired through the coax cable system.

Easy Expansion
Users can add more of these modulators to the setup at any time for accommodating more audio/video sources to be transmitted together and simultaneously over the same coax cable wire with the same high quality video with audio for high impact presentation.

More TVs and A/V modulators can be added to the existing setup for various applications such as:

• home entertainment
• educational training
• security surveillance 
• commercial advertisement/digital signage
• information display
• emergency messaging announcement 

Any TV that is connected through the same coax cable system can receive the signals when the TV is tuned to the proper channel. No cable boxes or satellite receivers needed at destinations. Tune in from any TV display or TV tuner and watch the same A/V content transmitted over the coax wire.

Cost-Saving Media Signal Transmission
Transmitting audio/video signals over existing coax cable setup offers far greater resolution, longer transmission range and much lower cost than the typical balun or Cat5 extender solution. Its high signal output of 100db is sufficient for long cable runs.

New A/V Distribution Over Cable TV System
This RF coax agile modulator is very suitable for professional A/V installers as well as end users to build a customized and centralized video distribution system for their own home A/V, satellite or security surveillance applications. 

Coax cable is not just for TV anymore. New innovations allow you to create your own customized TV broadcast system using various AV sources. No expensive A/V matrix routers required. Destinations do not need Cat5 interfaces, signage media players or set top boxes at all. Just tune in with any TV via the built-in TV tuner.

This type of composite A/V to RF coax modulator can be widely deployed in many applications such as:

• Must-have A/V adapter for older TV sets. For those older tube TVs with RF/coax input only, users can use this modulator to merge the separate composite RCA outputs from the source devices to the RF type first before connecting to their old TV sets.
• Cost saving with source device sharing. All TVs connected in the same coax cable can share the same A/V device. Simply tune in to the new channel and watch the same A/V content transmitted over the coax cable.
• Digital Signage. Using one single media player for each information channel and transmitted over multiple remote TV display at a very low cost.
• Custom built TV channels. Why wait for the cable company for more quality channels? Now you can combine free free-to-air digital broadcasts and satellite channels into your own cable system. Instructors or parents may also use this modulator to replace or override the inappropriate or unwanted TV channels for the audience.
• DIY private surveillance channel. Video and audio signals from CCTV surveillance camera can be presented on your TV channels. No additional video processor or separate video monitor needed for the setup any more. Check the live camera feeds on the TV by tuning into the preset channels for review or recording.

Universal Video System Support
One universal model fits for worldwide use with selectable system mode and wide channel frequency range support for all NTSC, PAL I, PAL B/G, PAL D/K and PAL-Australia. It is a frequency-agile analog audio/video modulator suitable for worldwide operation in the following ranges:

Adjustable Audio Video Gain Control
This composite A/V to coax RF converter is featured with adjustable gain control. Users can manually adjust and control the signal output level for easy integration with existing cable system. So the picture stability will remain the same as the original A/V input signal for the remote end display with minimum distortion and noise-free with full brightness and contrast.

Last Channel Memory
This video audio modulator will memorize user's setting for modulated channel after being powered off manually or power outage event.
