The 4-channel Thor Thunder-4 HDMI RF Modulator is a powerful device designed to encode and modulate HDMI sources into CATV RF channels. It supports Full HD resolutions up to 1080p/60 and enables seamless distribution of content over coaxial cables to multiple TVs equipped with QAM or ATSC tuners. This makes it an excellent choice for cost-effective video distribution in environments like hotels, schools, and residential setups.
Once connected to a coaxial network, the modulator allows TVs to scan and locate the channels easily. Users can then switch between channels using a standard TV remote, simplifying content delivery and management. The unit encodes video in MPEG-2 format and audio in either AC3 or MPEG1, ensuring compatibility with a wide range of devices.
The Thunder-8 is designed for user-friendly operation, offering two convenient control options:
Notably, the modulator is HDCP-compliant, meaning it works seamlessly with any HDMI source, including encrypted content.
For larger installations, multiple Thunder units (or a combination of Thunder-4 and Thunder-8 models) can be connected together to create up to 135 CATV RF channels. The 8-channel model is available under the part number Thunder-8, making it a versatile and scalable solution for high-density video distribution.
Additionally, this unit can generate any worldwide CATV RF modulation standard, including ATSC, DVB-C Annex A, DVB-C Annex B, DVB-T, and ISDB-T, ensuring global compatibility and flexibility for any application.
H- THUNDER-4 Supports 4 HDMI inputs and its modular design (maximum 4 HDMI inputs) and flexible configuration makes it scalable and very reliable while providing high performance.
The signal source could be from any STB, satellite receiver, closed-circuit television cameras, and antenna, etc. Its output signal is designed to work with any TV or STB. Because it comes standard with every RF modulation standard builtin, this device can work anywhere in the world in a plug and play format.
This unit is similar to our popular line H-1,2,4 HDMI-QAM-IPLL product line, but it has some differences. It is a less expensive unit, each program is modulated on its own frequency, CATV RF output only, no IPTV output
