All-Channel NTSC Composite BNC/RCA Video Audio To RF Coax
TV Modulator
This RF/coax agile modulator converts standard composite video/audio
inputs to a user-defined TV channel output. Any TV connected to the output from this A/V to RF modulator via
coax cable connection can receive the same A/V signal when tuned to the specific
channel.
All standard composite A/V signals from devices such as satellite receivers, Digital TV converter box, DVD player or CCTV surveillance camera can be modulated by this device into a cable TV channel frequency or UHF/VHF cannel frequency of user's choice, which can be combined with the existing cable TV system as one of your new TV channels.
More TVs and A/V modulators can be added to the existing setup for various applications such as:
Its programmable TV channel selection allows users to assign any desired TV channel frequency for its RF output. Channel selection is controlled by the front panel push button.
Multiple of these modulators can be combined together for broadcasting more A/V source signals and building up a large-scale TV distribution system for class rooms, hotels, restaurant, retail stores, hospitals.
Easy Operation
Simply connect the video/ audio output from device such as set top box,
sureillance camera, DVD
player to the RCA A/V input of this agile modulator and then
connect its RF coax output to your TV or a coax cable combiner/splitter for
further distribution.
Next use the push buttons and digital screen display located on the front panel to choose an unused or unwanted TV channel number for CATV system or UHF/VHF system use. At last simple use your TV remote to tune to the channel you just assigned for your DVD or camera video. Bingo !
Air/CATV Video System Support
This video/audio modulator is ideal for encoding audio/video onto
any unused TV channel. One model with selectable system mode and
wide channel frequency range support for both air UHF/VHF and CATV channel
output.
It is suitable for
operation in the following ranges:
Mode Code | TV System Support | Channel Frequency Range |
nC | NTSC-M (CATV) | CH2 to CH138 (48.25 MHz to 883.25 MHz) |
nA | NTSC-M (Air) | CH14 to CH83 (471.25 MHz to 885.25 MHz) |
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. Any TV connected to the output from this A/V to RF modulator via coax cable connection can receive the signals, when the TV is
tuned to the proper channel.
Simply using the TV remote to tune TV into the assigned TV channel by this RF modulator so the desired video content can be displayed on TV wired through the coax cable system.
Powerful 100db Output For
Long Range Transmission
This RF modulator is featured with a powerful 100dB output, which is
sufficient for long cable transmission up to 1200 meters with no loss of picture
and sound.
Analog video/audio signals transmitted over existing coax cable with such high dB strength can offers far longer distance than the typical balun or Cat5 extender solution.
Easy Expansion
Users can add more of these RF modulators at any time for more video sources to be transmitted simultaneously
through using RF combiner over the same coax cable wire with the same
high quality video for high impact pubic or private presentation.
Video Audio Extension Over Coax
Cable
Coaxial cables offer a low-cost solution for long distance signal
transmission line than the typical balun or Cat5
extender.
This RF modulator can also be combined with our RF demodulator, RFDM2 model, so they can be used as a video/audio over coax cable extender kit for many purposes such as CCTV surveillance, multimedia center, etc.
Other typical uses of this RF modulator including:
Adjustable Video Audio Level Control
This RF modulator is featured with adjustable level controls of the video/audio
input feed. Users can manually adjust the signal output level so the picture
stability will be retained all the way for the remote end display with full brightness and contrast.
1U 2U 3U 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 have multiple of these AV to RF modulators installed together on
rack chassis.
Rack mount kits are available in 1U, 2U or 3U style and sold separately.
Last Channel Memory
This video audio modulator will memorize user's setting for modulated channel after being powered off manually or power outage event.
