Videoprevodník Kramer Electronics VP-440X čierna 1080p 18W

VP−440X is a high-performance 18G 4K HDR presentation switcher/scaler with four HDMI inputs and one computer graphics (VGA) input. It scales video and embeds audio to two identical outputs — HDMI and HDBaseT — and also provides an unbalanced analog stereo audio output. Over HDBaseT the unit extends video up to 40 m (130 ft) over CAT copper cable at up to 4K@60Hz (4:2:0) 24bpp and supports longer distances for lower HD resolutions. The compact black aluminum housing and ½ 19” size allow installation in a 1U rack with the recommended adapter.

Advantages

The scaler offers up‑scaling, down‑scaling and cross‑scaling up to 4K@60 (4:4:4) with selectable output resolution and automatic chroma down‑sampling on the HDBaseT output when operating at 18G 4K. Smooth switching provides constant output sync to prevent glitches during input changes, even if a source has no signal. Audio handling is flexible: dedicated unbalanced analog audio can be embedded per input, a front‑panel microphone input supports mixing and talk‑over, and built‑in DSP provides equalization, mixing, delay and ducking. The unit is HDCP 2.2/1.4 and HDR10 compliant, supports EDID pass‑through and CEC forwarding, and provides bidirectional RS‑232 over the extension line for device control. Multiple control methods are available including front panel OSD, web interface over Ethernet, RS‑232 serial control, and contact closure for remote source switching and display ON/OFF.

Suitable for

• Presentation rooms and lecture halls requiring multiple HDMI and VGA inputs
• Meeting rooms where HDMI and HDBaseT outputs with audio embedding are needed
• AV installations that require HDR10 support, EDID pass‑through and HDCP compliance
• Systems needing DSP audio processing (mixing, EQ, delay, microphone talk‑over)

Key specifications

• Inputs: 4× HDMI, 1× VGA (computer graphics)
• Outputs: 1× HDMI, 1× HDBaseT, 1× unbalanced stereo analog audio
• Maximum video support: up to 4K@60Hz (scaling up to 4K, HDBaseT 4K uses 4:2:0 when 18G enabled)
• HDR support: HDR10
• HDCP: 2.2 and 1.4 compliant
• Audio processing: DSP with EQ, mixing, delay, ducking; front‑panel mic input
• Extension reach: HDBaseT up to 40 m (130 ft) at 4K@60Hz (4:2:0)
• Control: Front panel OSD, web GUI via Ethernet, RS‑232 serial, contact closure
• Physical: Black aluminum housing, ½ 19” size for 1U rack mounting; power consumption 18W; weight 1.1 kg

How to use

Connect sources to the four HDMI inputs or the VGA input, and connect displays to the HDMI and HDBaseT outputs. If using HDBaseT, run CAT cable to a compatible receiver placed near the remote display. Select the desired output resolution using the front panel OSD, web interface or serial commands; the unit can follow a sink’s native resolution or be set manually. Embed analog audio by assigning the unbalanced audio input to the required channel, or use the front‑panel microphone for mixing and talk‑over. Use the DSP settings to adjust EQ, delay and ducking as needed. For control and automation integrate the unit with the room control system via RS‑232, Ethernet (web GUI), or contact closure inputs for source switching and display power control.

Recommendations

For reliable 4K@60 performance over HDBaseT, use high‑quality CAT6a or CAT7 cabling and ensure the remote HDBaseT receiver and display support the required HDCP and HDR10 formats. When operating at 4K 4:4:4 output, verify downstream devices support the bandwidth; otherwise configure output scaling or allow automatic chroma down‑sampling on the HDBaseT output.
