High Sec Labs SX42PHU-N 4×2 DP/HDMI KVM Mini-Matrix switcher USB 3.0 Dual-Display Audio Mic

Description

The SX42PHU-N is a 4×2 DisplayPort/HDMI KVM mini-matrix designed to let a single operator view and control multiple computers across two console displays while preserving electrical isolation between systems. It consolidates keyboard, mouse, USB 3.0 peripherals and analog audio into a single chassis to remove the need for dedicated per-computer peripheral sets. The unit supports simultaneous presentation on two outputs and secure local switching controlled by front panel and keyboard commands.

Key features include four computer inputs selectable across two console outputs, four USB 3.0 host ports at the console, USB Type B connections to each computer and analog 3.5 mm speaker and microphone jacks. The device supports copy and paste file/text transfer between connected systems through the KVM without a network connection by using standard clipboard commands. The mini-matrix also provides full keyboard and mouse control across systems and maintains peripheral isolation for secure environments.

Performance specifications include support for UHD 4K resolutions depending on the variant and connection method with a maximum of 3840×2160 at 30 Hz or 60 Hz as supported by sources and outputs. The console uses DP/HDMI outputs while computer side supports DP/HDMI inputs for the SX42PHU-N model. Power consumption is rated up to 35W and the unit accepts 100 to 240V AC via an external power supply. Operating temperature range is 0 to 40 C and the product is certified to CE, FCC class B, VCCI, RCM, TUV US and TUV Canada standards.

Connectivity covers two console display outputs, two DisplayPort/HDMI inputs per computer port, USB Type A console ports for keyboard and mouse and USB Type B computer ports. Audio I/O consists of 3.5 mm speaker and microphone jacks on both console and computer sides to support analog audio capture and playback. Supported operating systems include Windows, Linux and Mac, enabling broad peripheral and driver compatibility in mixed-OS environments.

Typical applications include meeting rooms where host and guest systems must be presented side-by-side, control rooms that require constant multi-source monitoring across two displays and secure desks that need strict peripheral isolation while allowing data copy via the KVM. The mini-matrix is suited to scenarios where multiple computers must be simultaneously visible and controllable without adding per-computer peripheral sets. It simplifies workflows by centralizing USB 3.0 device access and analog audio switching.

Installation is straightforward – the compact 342 x 148 x 42 mm chassis mounts on a desk or equipment shelf and connects to sources using DP/HDMI cabling plus USB and audio leads. The external power supply reduces internal heat and simplifies maintenance while the 2 year warranty and 10 year product life-cycle support long-term deployments. Built certifications and BAA/TAA compliance help integration into government and enterprise environments where regulatory compliance is required.
