Tributaries Cable's two-piece HXMINI5


The two-piece HXMINI5 comprises a compact powered transmitter (a 9V power supply is included) and an equally compact passive receiver module. The transmitter has a single HDMI input from a source such as a set-top box or disc player. The receiver outputs the HDMI signal to a destination such as an HDTV set, HDMI switcher, or AV processor or receiver. The modules are linked using five 75-ohm mini or standard coaxial cables terminated with 75-ohm BNC connectors.

In combination with the HXMINI5’s active electronics, this wide-bandwidth interconnection supports hi-def 1080p/8 bit color HDMI signals over distances of up to 100 meters, 1080p/12 bit color up to 80 meters, and can even support 1440p signals in professional or future environments.

The new Tributaries extender is HDCP-compliant and is thus completely user-transparent with all HDMI-equipped components. And because it is also compatible with HDMI v1.3, it supports Dolby Digital and DTS digital audio transmission, as well as such latest generation HDMI features as Deep Color and CEC multi-component control.

According to Tributaries, the HXMINI5’s self-calibrating active amplification and equalization, and buffered output circuitry, automatically adapt to cable length and signal rate, eliminating signal losses, making it ideal for a retrofit where analog RGBHV cabling has already been installed.

Tributaries’ HXMINI5 speeds installation troubleshooting with five colored LED indicators that confirm power, as well as the signal integrity of the red, green, blue, and clock data streams. The HXMINI5 is available now, at a manufacturer’s suggested price of $500.
