The Extron DA HD 4K Series includes one input, multiple output distribution amplifiers for HDMI signals at resolutions up to 4K. They support data rates up to 10.2 Gbps, 3D, Lip Sync, and HD lossless audio formats, along with integrator-friendly features such as automatic input cable equalization, automatic color bit depth management, and selectable output muting. They also feature Extron EDID Minder® and Key Minder® technologies to maintain continuous EDID communication between connected devices and ensure simultaneous distribution of HDCP-encrypted source content. The DA HD 4K distribution amplifiers are available in sizes from two to six outputs, and are ideal for applications that require reliable distribution of a single HDMI source signal to multiple displays. To enhance and simplify integration, the DA HD 4K Series offers many integrator-friendly features. They provide automatic input cable equalization up to 50 feet, when used with Extron HDMI Pro Series cables. Input cable equalization restores and reshapes incoming HDMI signals, reducing the need for additional signal conditioning equipment by compensating for weak source signals or signal loss from a long input cable. Color bit depth is automatically adjusted based on the display EDID, which prevents color compatibility conflicts between source and display. Also, outputs can be muted independently via RS?232, allowing content to be previewed on a local monitor. The DA HD 4K distribution amplifiers provide immediate visual confirmation of HDCP authentication and signal presence for each port via front panel LED indicators. If HDCP?encrypted content is transmitted to a non?HDCP compliant display, a full?screen green signal provides immediate visual notification that protected content cannot be viewed on that display. HDCP authorization is user-selectable, allowing the unit to appear HDCP compliant or non?HDCP compliant to the connected source. This is beneficial if the source automatically encrypts all content when connected to an HDCP-compliant device. The DA HD 4K Series distribution amplifiers also provide +5 VDC, 250 mA on each output for powering peripheral devices such as an Extron UHD4K 101 or HDMI 101 Plus cable equalizer. The DA2 HD 4K is housed in a 1″ (2.5 cm) high, quarter rack width metal enclosure that can be mounted in a rack or discreetly installed beneath a desk or behind a display. It includes an external, universal power supply for worldwide power compatibility. The DA4 HD 4K and DA6 HD 4K are housed in 1U high, half rack width metal enclosures, are rack?mountable, and are equipped with internal universal power supplies.
