It supports Full HD resolutions, MPEG-2 encoding, and multiplexes 12 inputs into 4 RF frequencies (3 programs per frequency), making it ideal for efficient CATV, hospitality, or digital signage applications.

Setup is easy via LCD, Ethernet NMS, or wizard mode.

H-Thunder-12 is part of the acclaimed Thunder series of modulators, designed for professional-grade video distribution in environments like hotels, sports bars, educational facilities, and broadcast setups.

This rack-mountable unit features 12 HDMI inputs, supporting resolutions up to 1080p30 (with inputs handling 480i to 1080p60) and bit rates of 6-15 Mbps (default 9 Mbps) using MPEG-2 video encoding.

Audio options include MPEG-1 Layer 2, AAC, or AC3, with sampling rates of 44.1 kHz or 48 kHz.

Unlike other Thunder models that may output individual frequencies per channel, the H-Thunder-12 optimizes bandwidth by generating only 4 RF output frequencies (50-950 MHz range, 1 kHz step, 100 dBµV level with 30 dB attenuation), multiplexing 3 transport streams (TS) per frequency for a total of 12 programs.

It supports ATSC (8VSB constellation) and QAM J.83B (64QAM/256QAM) standards, with a typical MER of 35 dB for clean signal quality.

Front-panel controls include an LCD display, buttons for navigation, and status LEDs (dual-color for HDMI sources: green for connected, blue for no source; green for RF active; blue for LAN connected).

Rear connections feature 12 HDMI inputs, RF output, a LAN port for NMS, and AC power (100-240V 50/60Hz).

Configuration is user-friendly via Ethernet-based NMS (default IP: 192.168.0.188, admin/admin), with a dashboard showing channel/program status, bitrates, and resolutions.

Broadcast settings offer per-channel tweaks or a wizard for quick setup: select the standard (ATSC/QAM), frequency, and apply—the system auto-arranges channels and muxes programs.

Additional features include password changes, IP modification, firmware upgrades via Ethernet, factory reset, and reboot.

Weighing 2800g and sized at 484x300x44mm, it's built for reliable 24/7 operation.

This model stands out in the Thunder family for its efficient multiplexing, reducing RF channels while maintaining high-quality output, perfect for cost-effective multi-channel distribution over existing coax infrastructure.
