ATEN 5X2 True 4K Seamless Presentation Matrix Switch - VP3520

ATEN VP3520 5x2 True 4K Seamless Presentation Matrix Switch

Overview

The ATEN VP3520 is a 5-input, 2-output seamless presentation matrix switch designed for boardrooms, classrooms, and AV-over-IP rooms where sources change mid-presentation and display continuity matters. It routes True 4K signals — up to 4K@60Hz (4:4:4) — across both direct HDMI and long-haul HDBaseT outputs simultaneously, so a local display and a remote projector or display wall can receive the same or different sources without a separate distribution amplifier. If you're wiring a conference room where the presenter at the table needs to reach a screen 35–40 meters away over structured cabling, the VP3520 is purpose-built for that scenario.

The switch handles the full signal chain: video routing, audio mixing with a phantom-powered microphone input, relay control for projector lifts or screen drops, and network control via PJLink — all from a single 1U device. The ATEN AV switching line targets commercial integrators who need rack-mountable gear that fits standard IT infrastructure rather than bespoke AV cabling.

Key Features

• True 4K@60Hz (4:4:4) HDMI Output at 5m: Full-bandwidth 4K with no chroma subsampling on the local HDMI run — meaningful when you're feeding a high-end LED display or a medical-grade monitor where color accuracy matters. Extend to 10m at 4K@30Hz or 15m at 1080p@60Hz if your rack isn't immediately adjacent to the display.
• HDBaseT Output — 35–40m at 4K@30Hz over Cat 5e/6/6a: Run 4K content to a display 35m away over Cat 5e or Cat 6, or push that to 40m with Cat 6a or ATEN's 2L-2910 Cat 6 cable. At 1080p@60Hz, the reach extends to 60m (Cat 5e/6) or 70m (Cat 6a) — which covers most large conference rooms, auditoriums, and classrooms without pulling new fiber or coax.
• HDCP 2.2 Compliance: Full HDCP 2.2 support means protected content from streaming devices, Blu-ray players, and laptops with DRM-locked output passes through without handshake failures — a common pain point in boardrooms where executives connect personal laptops to display licensed content.
• Phantom-Powered Microphone Input (Captive Screw, 3-Pole): The mic input supports selectable phantom power, so you can connect a condenser microphone directly to the matrix switch without a separate preamp or mixer. The dedicated Mic knob and Volume knob on the front panel give presenters or AV techs physical control without digging into a control system interface.
• Stereo Audio I/O (Mini Jack + HDMI/HDBaseT Embedded): Audio is handled both as a discrete 3.5mm stereo input and embedded in the HDMI/HDBaseT signal paths — so a room with a dedicated audio system can break out audio at the switch rather than at the display, simplifying rack wiring when the amplifier is local but the screen is remote.
• 2x Relay Outputs (Captive Screw, 2-Pole): The dual relay outputs connect directly to projector screens, motorized lifts, or room lighting triggers. When a source is selected or the switch powers on, the relay fires — eliminating the need for a separate relay controller in straightforward room automation scenarios.
• PJLink Protocol over RJ-45: Network control via PJLink means the VP3520 integrates with virtually any room control system that supports the protocol — Crestron, AMX, Extron control processors, or a simple IP-based scheduler can command source switching, volume, and relay states without proprietary drivers.
• EDID Management (ATEN Default / Display A / Remix): Three EDID modes let you lock the sources to a known capability set, mirror the connected display's EDID, or blend capabilities across outputs. This prevents the common problem where a laptop defaults to a lower resolution because it detects an EDID mismatch when the matrix is in the signal path.
• Consumer Electronics Control (CEC) Support: CEC pass-through lets compatible displays power on/off in response to source switching events, reducing the number of separate control commands needed in simpler room configurations where full IP control isn't deployed.

Integration & Compatibility

The VP3520 operates on the presentation matrix switch standard physical rack form factor (rack and pole mount supported) and draws power from a standard 3-prong AC socket, so it fits into standard 1U rack infrastructure without external power bricks. For control integration, the PJLink RJ-45 port connects to managed network switches for IP-based control alongside room AV systems. Input resolution support spans 640×480 through 1080p/1080i/720p at 50Hz, covering legacy sources (document cameras, older laptops) up to full HD — 4K pass-through is handled natively on the video routing path.

For extended HDBaseT runs, ATEN's own 2L-2910 Cat 6 cable is validated to reach 40m at 4K@30Hz — a useful spec to confirm with your cabling contractor before pulling generic Cat 6 and expecting the same performance. Humidity tolerance is rated 0–80% RH non-condensing, appropriate for typical indoor conference, classroom, and auditorium environments. The device is not rated for outdoor or high-humidity installations.

Firmware is field-upgradeable (current release v1.1.103), so the unit can receive updates without replacement — useful in managed AV environments where control system behavior may evolve over the installation lifecycle. For larger room distributions or multi-zone deployments, review the broader ATEN AV matrix switching catalog to identify higher-port-count variants in the same family.

Frequently Asked Questions

Q: What is the maximum 4K resolution the VP3520 can pass over HDBaseT?

A: The VP3520 passes 4K@30Hz over HDBaseT at up to 35m on Cat 5e/6 or 40m on Cat 6a and ATEN 2L-2910 Cat 6 cable. Full 4K@60Hz (4:4:4) is available on the direct HDMI output at up to 5m only.

Q: Does the VP3520 support phantom power for condenser microphones?

A: Yes. The microphone input is a 3-pole captive screw connector with selectable phantom power, allowing direct connection of condenser microphones without a separate preamp.

Q: Can the VP3520 be controlled over IP from a room control system?

A: Yes. The VP3520 includes a dedicated RJ-45 Ethernet port supporting PJLink protocol, which is compatible with most commercial room control platforms including Crestron, AMX, and Extron processors that support PJLink.

Q: What cable category is required to reach 40m at 4K@30Hz over HDBaseT?

A: Cat 6a or ATEN's 2L-2910 Cat 6 cable achieves 40m at 4K@30Hz. Standard Cat 5e or Cat 6 is rated to 35m at 4K@30Hz. At 1080p@60Hz, Cat 5e/6 reaches 60m and Cat 6a reaches 70m.

Q: Does the VP3520 handle HDCP 2.2 protected content?

A: Yes. The VP3520 is HDCP 2.2 compatible, meaning it will pass copy-protected content from laptops, streaming devices, and Blu-ray players to connected displays without decryption errors.

Q: What relay functionality does the VP3520 provide?

A: The VP3520 includes two independent relay outputs via captive screw connectors (2-pole each), suitable for triggering motorized screens, projector lifts, or room lighting — without requiring a separate relay controller.

James Everett

The VP3520 is one of the more complete single-unit solutions I've seen for mid-size conference and classroom AV: it combines seamless 4K matrix switching, HDBaseT long-haul delivery to 40m over Cat 6a, a phantom-powered mic input, dual relay outputs, and PJLink IP control in a single rack unit. That's a lot of infrastructure that typically requires three or four separate boxes to replicate.

Technical Highlights:

• HDBaseT Distance Tiers: 35m at 4K@30Hz on Cat 5e/6, stretching to 40m on Cat 6a — gives you flexibility at the cabling stage rather than forcing a specific cable category on every run.
• Phantom-Powered Mic Input: Selectable phantom power on the 3-pole captive screw mic input means a condenser mic connects directly, reducing BOM and rack space in rooms that don't need a full audio DSP.
• EDID Remix Mode: The ATEN Default / Display A / Remix EDID options are the spec to nail down during commissioning — Remix mode prevents laptop sources from defaulting to 1080p when the matrix is in-line with a 4K display.

Deployment Considerations:

• Validate cable category before pulling runs: Cat 5e/6 caps at 35m for 4K@30Hz and 60m for 1080p@60Hz; Cat 6a or ATEN 2L-2910 unlocks 40m/70m respectively — a spec worth confirming with your cabling sub before walls close.
• The humidity ceiling is 80% RH non-condensing — the VP3520 is rated for climate-controlled indoor spaces only; it's not a fit for industrial, outdoor-adjacent, or high-humidity environments like natatoriums or loading dock AV.

Best fit for a corporate boardroom or higher-education classroom where the integrator needs 4K source switching, a single 40m HDBaseT run to a remote display, local mic mixing, and IP control — all commissioned without a separate relay controller, audio mixer, or secondary control processor.
