4K Ultra HD 600 MHz Multi-Format 5x1 Scaler

w/ Auto-Switching & Split HDMI & HDBaseT Outputs


Auto-Switch 4K Ultra HD 600 MHz HDMI, DisplayPort 1.2 and VGA. Scale and extend up to 70 meters/230 feet, over a single CAT-5.

The EXT-4K600A-MF-51-HBTLS is a 5x1 Presentation Switcher with three 4K 600 MHz HDMI, one DisplayPort 1.2, one VGA, five independently assignable stereo analog audio, & one balanced/unbalanced microphone/line input. The latter features switchable 48V Phantom Power and Ducking. The five video inputs, along with their embedded or assigned audio, can be switched automatically or manually. Control options include the front panel, hand-held IR remote with On-Screen-Display, electrical IR, RS-232, Telnet/UDP, web server interface, & contact closure.

The split HDMI and HDBaseT outputs feature a scaler, configurable to 3840 x 2160, 30 Hz, 4:4:4. They feed a local and a remote display simultaneously, adding flexibility in larger presentation environments. The Switcher and its recommended Receiver (the EXT-UHDA-HBTL-RX, sold separately) use Gefen’s implementation of the HDBaseT™ technology to extend the HDMI output of the Switcher up to 230 feet/70 meters at 1080p Full HD and up to 130 feet/40 meters at 4K, using one CAT-5e or better cable. The HDMI and DisplayPort™ inputs support resolutions up to 4K DCI (4096 x 2160) 60 Hz 4:4:4, with HDCP 2.2 and 1.4. The HDMI input & output, and the HDBaseT™ output support 2 channels of LPCM digital audio. The VGA input supports resolutions up to WUXGA (1920 x 1200) and 1080p Full HD. When used with third-party adaptors, the VGA input also supports Component (YPbPr) and Composite video. The Switcher features an analog L/R audio de-embedder. The optional Receiver also features analog and digital audio (optical and coaxial) outputs. Any or all audio outputs can be connected to sound-reinforcement systems at the source side or the remote end, adding impact and presence to AV presentations. The 5x1 Switcher features Advanced EDID Management to ensure that sources are optimized for the displays in use. The Switcher, when used with the optional HDBaseT™ Receiver, provides 2-way RS-232 and IR extension, facilitating control of the Switcher, AV sources placed near the Switcher, and the remote display or another device placed near the Receiver unit. Industry-standard Power-Over-HDBaseT™ (POH) technology provides power from the Switcher to the Receiver, over the same cable that extends the AV signal. The Switcher features an integrated IR Sensor on its front panel as well as an electrical IR input. If the switcher is mounted in a location where its IR sensor is not within line of sight, a Gefen EXT-RMT-EXTIRN IR Extender Module or a third-party controller with electrical IR output can be connected to the IR input on its back panel. The 5x1 Switcher features a compact form-factor that can be placed on a shelf or securely mounted on or under a surface. The optional Receiver’s small, ultra-low-profile enclosure can be securely surface-mounted, and conveniently hidden away from sight in the equipment closet or behind the display. Locking HDMI ports on the Switcher & locking power jacks on both units ensure long-lasting and reliable connections.

Shielded (STP) CAT-5e or better cable is recommended. Unshielded (UTP) CAT-5e or better cable may be acceptable depending on cable quality but is not the preferred choice. Care should always be given to keep these cables away from power lines and other sources of electromagnetic interference.
