Professional RF Coax To Composite Video Audio Demodulator TV Tuner
For NTSC System
This coax to composite A/V demodulator is a professional grade
TV channel converter, designed to work with coax TV signals such as cable
TV or satellite channels, closed circuit TV channels or other RF
modulated signals by converting such coax feeds into
standard composite RCA formats for various applications such as displaying,
recording, or further A/V broadcast and distribution.
This coax cable signal converter provides convenient
decoding solution for extracting the video/audio embedded in the coax RF signals coming from cable outlets or cable boxes, satellite
set top boxes or CCTV camera/DVR systems. Its availability
offers cost-efficient solution and helps for those
coax setups found in public A/V broadcast, MATV, SMATV systems used in campus, classrooms, hotels,
condos, hospitals, sports bars, restaurants or individual residence.
This coax cable signal demodulator
can also be used a stand alone TV tuner. Featured with support of full TV
channel frequencies and the micro processor inside the unit can decode all standard UHF/VHF TV, CATV and satellite
channels for NTSC systems.
This device supports all the coax type
A/V signal inputs from:
- cable box or cable outlet for analog TV system.
- private UHF/VHF TV broadcast through RF
antenna
- satellite receivers with coax out
- digital signage set top boxes with coax outputs
- modulated surveillance CCTV system
- Cable radio or cable FM station
- A/V modulators used in MATV setup
This converter provides clear and smooth video
with great sonic
quality. No noise and no interference after the long distance
transmission. Once
demodulated, the selected channel can be output to TV, video monitor, projector,
multiplexer, A/V receiver, video recorder and so on.
Easy 1-Minute Setup
Simply connect the coax cable from your coax feed source to the coax input of
this converter and then use regular composite A/V cable to connect from the standard
RCA video /audio output of this coax converter to a TV display or video
recorder.
No initial configuration setup needed. No TV
channel scan needed. 100% hardware operation with easy cable setup.
Full-Frequency TV Channels For CATV Satellite
This coax demodulator doubles as an external TV tuner for all the TV video displays.
This agile demodulator has a full-frequency analog tuner
and able to decode all standard NTSC channels within the range of 48.25 to
883.25MHz. In other words,
it supports all standard TV channels from CH1 to CH139.
The
RF input of this coax to RCA demodulator can also be used for those satellite
receivers with TV2 out from DirecTV, Dish Network and FTA satellite for regions
using NTSC for TV broadcast system. Check
your satellite receiver first and make sure that the
coax output from your satellite box can be set for certain channel number.
Easy Add-On TV Tuner Module
This coax
demodulator can be a great add-on TV tuner
module for video monitors, projectors, DVR systems or all other video equipments
that do not have coax inputs.
Users can simply connect the RCA
video/audio output of this tuner module to a video monitor, projector, recorder
or mixer console and instantly expand their A/V equipments with a new RF/coax input
for accommodating the signals coming from cable
TV outlets, satellite receivers or modulated CCTV surveillance systems.
Great Coax To Stereo Audio Demodulator For Home
Theater System
This demodulator can also doubles as the coax to stereo audio converter. It can extract the audio
sound tracks embedded from
the TV channels to stereo L/R channels in standard RCA format for further
distribution. So users will not be
limited by using typical TV speakers for sound output since this coax
converter demodulator give users the capability to play or record
the TV sound tracks or TV radio channels from their cable systems through
individual A/V receiver or stereo system for in-depth sonic experience.
For those who got tired of the low-volume TV speakers and would like to
extract TV sound from the coax cable or satellite feeds and send through
their favorite stereo amp, receiver, Hi-Fi speaker, headphone or home theater system, this
coax audio module answers those requests.
For
those older TVs without audio out ports, this unit can also provide users a solution to
extract the TV sound from the coax feed and send the audio to their headphone sets so they can
enjoy private listening without bothering others.
TV Channel
Number LED Display
The TV channel number will be displayed on the front panel to show the TV channel
number currently selected by users like a cable box.
Optional
IR Remote Controller
This external TV tuner can also be fully operated and controlled via the
optional IR remote controller or push buttons on the front panel, just like the
way we were using the TV remote to flip between channels, mute the TV sound or
up the volume. [Note]: The
IR remote controller is sold separately.
Video Audio Capturing
Once decoded by this coax demodulator unit, your coax feed
for the selected cable TV or satellite TV channel can be transcoded into
standard video/audio in RCA format for recording by DVD recorder, DVR, computer-based capturing device or other type of video/audio recorders.
Last
Channel Memory
This coax demodulator tuner unit will stay tuned to the same last TV channel
when the power comes back up after a power outage event or users unplugging the power
adapter manually.
Auto Gain Control
This coax to composite A/V converter is featured with AGC
circuitry for auto adjustment on both video and audio levels. The output quality
will be re-calibrated and retained the picture
stability as the original input A/V signal for the remote end display with minimum distortion and
noise-free with full brightness and contrast.
Rack-Mountable
This unit is compact in size and it is rack mountable if needed for
large-scale broadcast TV system or surveillance camera CCTV setup. Multiple
units can be daisy chained together on 19" rack using the optional rack
mount
kits. Rack-mount kits are not included in standard packages and they are sold separately.
