Adder X-USBPRO-MS2 – Dual VGA USB Audio CATx Extender 300m

Product Overview

The Adder X-USBPRO-MS2-US (AdderLink X-USB PRO MS) is a dual-head VGA KVMA extender that carries two VGA video streams, transparent USB 2.0, and stereo audio up to 300m (1000 ft) over a single CATx cable. It is built for multiscreen desktop environments where the workstation must sit far from its computer — across a building, a campus riser, or a production facility — without sacrificing image quality or peripheral compatibility. As a long-range VGA KVM extender over CATx with a built-in USB hub and dual-user capability, the X-USB PRO MS2 keeps analog video installations crisp at full distance through multi-pole compensation and adjustable skew correction.

Product Description

The system extends VGA resolutions up to 1920x1200 @ 60Hz across the full 300m reach, using a multi-pole compensation technique with color skew compensation and gain adjustment controlled directly from the receiver's keyboard. A variable noise filter handles runs beyond 200m, so even legacy analog displays at maximum distance present clean, sharp images.

The receiver contains a four-port USB hub supporting low and full-speed USB — including isochronous devices — so a complete desktop can be relocated: keyboard, mouse, disk drive, flash stick, webcam, and other USB peripherals all operate remotely. CD-quality stereo audio (2-channel, 16-bit at 44.1kHz) feeds remote speakers, and a local feed-through port for audio and video lets a console remain in use at the machine end. A notable capability for shared systems: two X-USB PRO units can be linked to one computer's USB sub-system, enabling two users at separate multiscreen desks to access the same machine simultaneously.

The USB-powered transmitter reduces the need for outlets at the rack (an external supply serves as backup), full two-page DDC EDID emulation mirrors the source monitor's data exactly, and both metal-cased units can sit on a desk or mount up to 16 per 2U chassis for high-density installations. Distance scales with cable grade — 200m on CAT5, 250m on CAT5e, and 300m on CAT6 or CAT7 trunk cable.

Key Features

• 300m Single-Cable Extension — Dual VGA, USB 2.0, and stereo audio reach up to 300m (1000 ft) over one CATx run, with distance scaling by cable grade.
• Full-Distance Video Quality — VGA up to 1920x1200 @ 60Hz with multi-pole compensation, 62ns de-skew at 2ns resolution, and gain adjustment from the receiver keyboard.
• Complete Remote Desktop via USB Hub — The receiver's 4-port hub supports keyboards, mice, drives, flash sticks, webcams, and other low/full-speed devices, including isochronous types.
• Dual-User Configuration — Two units linked to one computer's USB sub-system give two operators simultaneous access from separate consoles.
• Local Feed-Through Port — Audio and video pass-through keeps a local console usable at the computer end.
• CD-Quality Stereo Audio — 2-channel 16-bit audio at 44.1kHz with THD+N typically -80dB and SNR typically 85dB at 1kHz.
• USB-Powered Transmitter — Runs from the host USB connection with external power as backup, minimizing rack outlets.
• Two-Page DDC EDID Emulation — The remote system mirrors the exact monitor data from the source display for correct output.
• High-Density Rack Option — Up to 16 units mount in a 2U chassis, or use the units stand-alone on the desktop.

Typical Applications

• Broadcast studio multiscreen consoles fed from a central machine room
• Government space operator desks separated from secured computers
• Training room dual-instructor access to a shared teaching system
• Auditorium and multi-purpose room control positions far from equipment racks

Technical Specifications

Frequently Asked Questions

How far can I extend, and what cable do I need?
Up to 200m on CAT5, 250m on CAT5e, and 300m on CAT6 or CAT7 trunk cable. Patch cable runs reduce achievable distance.

Will the image stay sharp at maximum distance?
Yes. Multi-pole compensation, color skew correction (62ns de-skew at 2ns resolution), gain adjustment, and a variable noise filter for runs over 200m maintain image quality at 1920x1200 @ 60Hz.

Can two people use the same computer?
Yes. Two X-USB PRO units connected to a single computer's USB sub-system allow two users to access the system simultaneously from separate multiscreen desks.

What USB devices are supported at the remote desk?
All USB 1.1 full/low-speed devices and USB 2.0 devices operating in those modes — including keyboards, mice, storage, webcams, and other isochronous devices — through the receiver's 4-port hub.

Does the transmitter require mains power?
The transmitter is USB-powered from the host computer, with an external supply available as backup. The receiver uses the included power adapter.

What operating systems are compatible?
All known operating systems, including Windows, DOS, Linux, UNIX, BSD, Sun OS, Solaris, Mac OS, and NetWare. No drivers are required.
