Adder AV4PRO-DVI-US – AdderView 4 PRO 4-Port DVI USB KVM Switch

Product Overview

The Adder AV4PRO-DVI-US (AdderView 4 PRO DVI) is a professional 4-port DVI KVM switch that lets one operator control four computers from a single high-resolution console with USB 2.0 peripheral and audio switching. Full dual-link DVI-I video supports up to 4-megapixel resolutions at 60Hz from digital or analog sources, while Adder's USB True Emulation technology keeps keyboard and mouse continuously emulated to every computer for instantaneous, reliable switching. Buyers comparing a 4-port DVI USB KVM switch, a dual-link DVI KVM with audio, or a desktop KVM switch for editing and operator workstations will find the AV4PRO a proven professional-grade choice.

Product Description

Multi-system desks — edit suites, operator consoles, engineering benches — lose time and desk space when each computer has its own keyboard, monitor and mouse. The AV4PRO-DVI consolidates four machines onto one console without compromising video fidelity: its dual-link DVI-I ports carry up to 4-megapixel digital video at 60Hz, and because the connector is DVI-I, analog sources can be accommodated as well.

Where conventional KVM switches merely pass USB signals through, Adder's True Emulation technology presents a fully emulated keyboard and mouse to each connected computer at all times. The result is hotkey channel changes that complete instantly, with no re-enumeration delay and no lost keystrokes — critical on desks where operators bounce between systems continuously.

Two additional independently switchable USB 2.0 channels give the desk real flexibility: a printer, storage drive or audio interface can remain attached to one computer while the console follows another, or everything can switch together. The analog audio channel (3.5mm stereo) switches independently as well, so program audio can keep playing from one machine while you work on a different one.

The AV4PRO family is widely deployed in professional AV, post-production and control environments, and pairs naturally with the rest of the Adder Technology range at Creation Networks when desks grow into extended or matrix systems.

Frequently Asked Questions

What is USB True Emulation and why does it matter?
True Emulation continuously presents an emulated keyboard and mouse to each of the four computers, so channel changes are instantaneous and reliable — no USB re-enumeration pause and no dropped keystrokes.

Can I connect analog video sources?
Yes. The switch uses DVI-I connectors, which accept either digital or analog signals, with full dual-link digital support up to 4-megapixel resolutions at 60Hz.

Can a USB printer stay connected to one computer while I work on another?
Yes. The two extra USB 2.0 channels switch independently of the console, so peripherals can be assigned to specific computers or follow the active channel.

Does it switch audio?
Yes. The 3.5mm stereo audio channel switches independently, so program audio can continue from one machine while the console controls another.

Will it work with Windows, macOS and Linux machines at the same time?
Yes. The switch is OS-independent and mixed platforms can be connected simultaneously.

What cables do I need?
Each computer requires a DVI video cable, a USB Type A-to-B cable and an optional 3.5mm audio lead. Combined Adder cable sets are available; contact us for recommendations.
