Composite Video Audio To RF Coax Agile Modulator For CH23 To CH52
The RF Agile Modulator accepts standard video/audio input from any composite video source and modulates the signal to a CATV channel of your choice. 

All standard A/V signals from devices such as satellite receivers, Digital TV converter box, DVD player or security surveillance camera can be modulated by this device to become a new TV channel and merge with your existing coax cable TV system. Image that you can tune to a channel on your TV and finish watching a DVD movie you started in a different room or see who is knocking on the door.

Its featured programmable channel selection allows users to assign a proper TV channel between CH23 and CH52 for the audio video signal source connected to this agile modulator.

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

Channel tuning is easily accomplished with the use of front panel push button switches. All channel frequency information is pre-programmed and tuned electronically via microprocessor. Its agility feature offers great  flexibility in assigning TV channel line-ups.

Easy Operation
This RF modulator is very easy for installation. Simply connect the video and audio output from device such as DVD media player, satellite, Digital TV converter or video camera to this unit and then connect the coax output from this unit to your local TV or coax combiner/splitter. Next use the channel up/down buttons on the front panel to assign an unused or unwanted TV channel number in the range between CH 23 and CH 52 for NTSC TV.

Lastly use your TV remote control to tune to the channel you just assigned and instantly you will be watching your DVD or satellite video or surveillance camera video on the TV.

Easy Expansion
Multiple units can be cascaded together to broadcast multiple audio video inputs from various central sources. At any time users can add additional agile modulators to the setup for incorporating more audio/video sources such as DVD player, DVR, CCTV camera, digital signage player or additional satellite receivers.

Multiple A/V media contents can be transmitted together and simultaneously over the same coax cable with the same high quality video with audio for high impact presentation for long range A/V distribution on multiple TV channels. You can also add more TV sets to the existing setup for many different applications such as:

• Home entertainment
• Educational training
• Security surveillance 
• Commercial advertisement/digital signage
• Information display
• Emergency messaging announcement 

Any TV connected through the same coax cable system can receive the same video audio signals modulated into different channels. 

Long Range Media Signal Transmission
Transmitting audio/video signals over existing coax cable setup offers longer transmission range and much lower cost than the typical balun or Cat5 extender solution. Its high signal output of 100db is sufficient for driving multi-channel video channel over the long cable runs up to 1200 meters.

Video Audio Distribution Over Coax CATV 
No expensive A/V matrix routers needed any more for signal distribution and broadcast. This new innovation allows users to create customized TV broadcast system by transforming the standard outputs from any A/V device into private closed circuit TV channels. Any TV hooked up through the coax cable can access those new private channels using the remote. 

This type of AV to RF coax modulator can be widely deployed in many applications such as:

• Closed-Circuit Private Channels:
  Regular home users can use this product to combine free-to-air digital broadcasts and satellite channels into your own cable system. Instructors or campus can use this product to create new closed-circuit channels and broadcast the multimedia content through internal RF system for information and training purposes.  Parents may also use this modulator to replace or override the inappropriate or unwanted TV channels for the benefit of young audience.
• Source Device Sharing:
  Single A/V device or media player can be shared by multiple TV displays. All TVs connected through the same coax cable can view the new private channels created by this modulator.
• Digital Signage: 
  The A/V output from a signage player can be modulated by this device for creating new information channel and transmitted over multiple TV displays at remote location with very low cost in the setup.
• Video Surveillance:
  Video and audio signals from CCTV surveillance camera can be presented on a unused TV channel. No separate video monitor needed for the setup any more. Check live camera feeds on the TV using the remote at any time for monitoring or recording.
• Must-have A/V Adapter For Old TVs: 
  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.

Adjustable Video Audio Control
This A/V to RF coax converter is featured with adjustable controls on video signal level, audio volume and gain. 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.

Rack Mountable Design
This agile modulator is rack mount ready. There are rack-mounting holes on the front panel. The optional rack-mount kit can be purchased separately to have multiple of these AV to RF modulators installed together on a 1U, 2U or 3U rack chassis. 

Last Channel Memory
This video audio modulator will retain the channel setting after being powered off manually or power outage event.

• Professional quality RF coax modulator with microprocessor-controlled channel tuning.
• Converts standard composite video and audio inputs to a user-defined CATV channel from CH 23 to CH 52 (217.25 - 239.25MHz) for NTSC system.
• Digital crystal PLL modulation.
• Transmitting audio/video over existing coax cable offers longer range transmission at much lower cost than typical balun or Cat5 extender solution. 
• Agile channel selection allows maximum flexibility in altering TV channel line-ups and instant replacement of existing channels.
• Supports all audio/video sources such as satellite receivers, media players, video camera or other A/V devices with standard composite video audio outputs.
• Must-have A/V adapter for older TV display. For those older tube TVs with coax input only, users can use this modulator to merge both the composite video and audio from the source device into RF signal on a standard TV channel.
• Cost saving with source device sharing. All TVs connected in the same coax cable system can share the same A/V device or media player.
• Video and audio signals from CCTV surveillance camera can be presented on your TV channels.
