Comutador de matriz de apresentação ATEN 4 x 2 True 4K

The ATEN VP1421 is a compact multi-in-one presentation switch that combines a video matrix, True 4K scaler, HDBaseT extender, audio DSP and analog-to-digital conversion in a single metal enclosure. Designed for meeting rooms and educational spaces, the VP1421 supports resolutions up to 4096 x 2160 @ 60Hz (4:4:4) with HDR and provides flexible input and output options for presentations and video conferencing.

Advantages

The VP1421 delivers True 4K HDR visual clarity and simultaneous scaling to 4K and 1080p, enabling sharp, accurate images across displays. It supports up to four inputs (1 HDBaseT, 2 HDMI, 1 VGA) with smooth source switching and built-in HDBaseT transmission over a single Cat6/Cat6a cable up to 140 m, carrying AV, power and bi-directional RS-232/IR control. An onboard audio DSP provides microphone support with selectable 48V phantom power, automatic program-audio ducking for clearer speech, and flexible embedding/de-embedding to HDMI, line out and optical outputs. Multiple control options — front-panel buttons, IR remote, web GUI, RS-232, Ethernet and contact closure — simplify integration and operation.

Suitable for

• Corporate meeting rooms and boardrooms
• Lecture halls and classrooms
• Small-to-medium conference spaces and training rooms
• Video conferencing systems requiring multiple inputs and flexible audio routing

How to use

Connect source devices to the available inputs (HDBaseT, HDMI, VGA), connect displays to the HDMI and/or HDBaseT outputs and, if needed, run a Cat6/Cat6a cable to extend AV and control up to 140 m. Configure scaling, audio embedding and routing via the front-panel controls, the web-based GUI or an external control system using RS-232 or Ethernet. When using a microphone, enable the 48V phantom power if required and adjust the audio DSP settings to mix mic and program audio and apply automatic ducking for speech intelligibility.

Recommendations

For optimal HDBaseT performance use high-quality Cat6 or Cat6a cables (ATEN recommends 2L-2910 Cat6 for best results), ensure firmware is up to date, and verify display EDID settings when mixing 4K and 1080p outputs to avoid resolution or color-space mismatches.
