The Gefen EXT-HDMI1.3-141SBP Super Booster PLUS is an active signal conditioning and extension device engineered to resolve common signal integrity issues in HDMI installations. Its primary function is to regenerate a degraded HDMI signal, allowing for reliable transmission over longer cable distances than would typically be possible with a passive cable alone. By integrating an equalization and reclocking circuit, the device actively reconstructs the incoming digital signal, correcting for jitter and compensating for high-frequency loss caused by cable attenuation. This process restores the signal's original timing and amplitude, outputting a clean, robust signal that can drive an additional length of cable to reach a distant display, effectively extending the total reliable connection distance.

This model is specifically designed for the HDMI 1.3 specification, which introduced support for higher bandwidth features like Deep Color, xvYCC wide gamut, and high-bitrate Dolby TrueHD and DTS-HD Master Audio audio formats. The booster ensures these advanced signals are maintained without corruption over extended runs. It is particularly valuable in home theater installations, digital signage networks, and conference rooms where the source equipment—such as a Blu-ray player, AV receiver, or media PC—must be located far from the display or projector, a scenario where signal dropouts, sparkles, or complete handshake failures often occur.

The device is housed in a compact, plug-and-play enclosure that requires external power via an included adapter. Its operation is transparent, requiring no user configuration; it automatically handles HDMI handshaking and EDID communication between the source and display. By serving as an in-line signal regenerator, the Super Booster PLUS effectively functions as a one-port distribution amplifier, solving distance-related performance issues without the complexity of a larger matrix or extender system. It provides a cost-effective and reliable solution for achieving stable, high-definition audio and video delivery in challenging installation environments where standard cables fall short.
