How does the Dante audio integration work on the VLPT-51HT70?

The VLPT-51HT70 includes a dedicated Dante RJ45 port supporting 2x2 Dante audio I/O at 44.1, 48, 88.2, or 96kHz at 24-bit, with configurable latency of 2, 3, 4, 5, or 10ms. A built-in 3x3 audio matrix routes analog, Dante, and HDMI-embedded audio with independent EQ, volume, and delay per channel. Dante audio can be embedded into or de-embedded from the HDMI/HDBaseT outputs.

Can I control a PC at the switcher from the display end of the room?

Yes. The VLPT-51HT70 supports USB 2.0 KVM over HDBaseT. Keyboard and mouse connected to the receiver's USB device ports can control the USB host at the switcher, and USB 2.0 devices can be extended in both directions at up to 350–480Mbps. This eliminates the need for a separate KVM extender in most room installations.

Product Description

The VLPT-51HT70 is a 5x1 seamless presentation switcher that consolidates three HDMI sources and two USB-C sources into a single display output, with a mirrored HDBaseT 3.0 output extending the signal up to 230ft/70m over a single CAT6A cable — and the HDBaseT 3.0 receiver is included. The two USB-C inputs support DisplayPort Alt mode for 4K/18Gbps video, USB 2.0 data pass-through, 100m Ethernet pass-through to a connected laptop, and 60W charging, making them purpose-built for BYOD meeting rooms where participants need a single-cable connection experience. HDCP 2.2 compliance and advanced EDID management ensure compatibility with the full range of modern display devices, while automatic and manual input switching modes accommodate both room-automation and walk-up presentation workflows.

The VLPT-51HT70 is equally capable as an audio hub. A built-in 3x3 audio matrix with independent EQ, volume, and delay adjustment per channel handles both an analog audio input/output (via phoenix connector) and Dante® 2x2 networked audio input/output — enabling routing of program audio, microphone feeds, or room reinforcement audio across the same infrastructure as the video.

Local USB 2.0 KVM switching lets users control a host PC directly from the display end of the room, while bidirectional RS-232 and IR pass-through enable control of external devices at both the transmitter and receiver ends. Flexible control is available via front-panel buttons, IR remote, RS-232, TCP/IP, and a web GUI.

Ideal Applications

Corporate Conference Rooms and Huddle Spaces

The VLPT-51HT70 is purpose-built for modern meeting rooms where multiple presenters need a seamless, single-cable connection experience. The two USB-C inputs let laptop users connect with a single cable and receive 4K video output, USB 2.0 data, Ethernet access, and 60W charging simultaneously — eliminating the dongles and adapters that slow down meeting starts. The included HDBaseT 3.0 receiver mounts cleanly at the display wall, extending the signal up to 70m from the equipment rack or credenza. Manual and automatic input switching keep transitions clean whether the room is managed by a control system or used as a walk-up space.

Higher Education Lecture Halls and Classrooms

Large lecture halls and tiered classrooms benefit from the VLPT-51HT70's ability to accept video from multiple instructor and guest sources while extending the signal the full length of the room. A professor's laptop, a document camera, a desktop workstation, and a guest presenter's USB-C device can all be connected simultaneously, with seamless switching between them. KVM functionality over HDBaseT allows the instructor to control a PC from the display end of the room, and Dante® 2x2 audio integration enables routing of room microphone feeds and program audio over the same network infrastructure as video.

Government and Defense Briefing Rooms

Classified and secure briefing environments require reliable, fully wired presentation infrastructure without wireless dependencies. The VLPT-51HT70 provides exactly that — five discrete wired inputs, HDCP 2.2 content protection, and a fully contained HDBaseT 3.0 distribution chain with the receiver included. Bidirectional RS-232 and IR pass-through enable remote equipment control without exposing additional network attack surfaces. Advanced EDID management ensures that connected sources and displays negotiate correctly every time, preventing the display failures that are unacceptable in high-stakes briefings.

AV Integration in Hospitality and Event Spaces

Hotels, convention centers, and multi-purpose event venues require presentation infrastructure that adapts to different presenter types — from keynote speakers with MacBooks to AV technicians patching in rack equipment. The VLPT-51HT70's mix of USB-C and HDMI inputs, combined with PIP/PBP/Triple/Quad multiview modes, provides the flexibility to display content from multiple sources simultaneously for panel events, live demos, or split-room configurations. Analog and Dante® audio pass-through supports integration with room sound reinforcement systems, and the 70m HDBaseT range reaches displays in even the largest ballroom configurations.

Training Centers and Corporate Learning Environments

Training facilities that rotate between instructors, guest presenters, and remote participants need a switcher that accommodates any connection type without IT intervention. The VLPT-51HT70's automatic switching mode activates the active source immediately, while USB-C Power Delivery charging keeps trainers' laptops charged through long sessions. KVM over HDBaseT lets a single host PC be controlled from either end of the room, enabling a facilitator at the display to drive the instructor's workstation. The built-in audio matrix with independent delay adjustment ensures synchronized audio for recording and live-stream workflows common in modern training environments.

Frequently Asked Questions

What does the included HDBaseT 3.0 receiver provide?

The VLPT-51HT70 ships with a complete HDBaseT 3.0 receiver, giving you a ready-to-deploy transmitter-and-receiver system out of the box. The receiver provides an HDMI output for connecting to the room display, an analog audio output (LINE OUT via 5-pin phoenix connector), USB 2.0 host port and two USB device ports for peripheral extension from the TX end, bidirectional RS-232 and IR pass-through for display or device control, and a service port (Micro USB) — all powered over the single CAT6A cable from the switcher via PoE (RX_PD).

How far can the VLPT-51HT70 extend 4K video over HDBaseT?

The VLPT-51HT70 extends uncompressed 4K@30Hz and 1080p signals up to 230ft/70m over a single CAT6A (F/FTP) cable. For 4K@60Hz 4:4:4 signals, the maximum range is 131ft/40m. Cable quality and termination matter: use a shielded CAT6A (F/FTP) cable with proper 568B termination, direct interconnection is required (do not use crossover cables). The HDBaseT output also carries PoE to power the included receiver, USB 2.0 data, and RS-232/IR control signals over the same cable.

What can the USB-C inputs do beyond video?

Each of the two USB-C inputs on the VLPT-51HT70 is a full-featured connection, not just a video input. In addition to carrying 4K/18Gbps video via DisplayPort Alt mode, each USB-C port passes USB 2.0 data to the switcher's USB host, provides 100M Ethernet connectivity directly to the connected laptop, and delivers 60W Power Delivery charging to keep the user's device charged during a presentation. This makes the USB-C inputs ideal for BYOD (bring-your-own-device) meeting rooms where participants want a single-cable docking experience.

What multiview display modes does the VLPT-51HT70 support?

The VLPT-51HT70 supports five multiview display modes: Single (full-screen), PIP (Picture-in-Picture), PBP (Picture-by-Picture), Triple (three sources on screen), and Quad (four sources on screen simultaneously). These modes are available via the front-panel buttons, IR remote, RS-232, TCP/IP, or web GUI. The switching between single full-screen inputs is seamless, while multiview layouts enable fast-switching between sources in environments where simultaneous source monitoring is needed.

How does the Dante® audio integration work?

The VLPT-51HT70 includes a dedicated Dante® RJ45 port on the switcher, supporting 2×2 Dante® audio input and output at sample rates of 44.1, 48, 88.2, or 96kHz at 24-bit depth, with configurable latency of 2, 3, 4, 5, or 10ms. The built-in 3×3 audio matrix routes signals between the analog input, Dante® input, and HDMI-embedded audio, with independent EQ, volume, and delay (0–50ms sync delay) adjustable per channel. Dante® audio can be embedded into the HDMI/HDBaseT output or de-embedded for separate routing — managed through the built-in web GUI or Dante® Controller software.

Can I control a PC connected at the switcher from the display end of the room?

Yes. The VLPT-51HT70 supports local USB 2.0 KVM switching, meaning a keyboard and mouse connected to the USB device ports on the receiver can control the USB host connected to the switcher — effectively providing KVM control over the HDBaseT 3.0 link. You can also extend additional USB 2.0 devices (drives, cameras, peripherals) from the TX side to the RX host or from the RX side to the TX host at up to 350–480Mbps depending on the direction. This eliminates the need for a separate KVM extender in most room installations.

What control options are available for the VLPT-51HT70?

The VLPT-51HT70 supports six control methods: front-panel buttons, the included IR remote, RS-232 serial control (via 3-pin phoenix connector), TCP/IP over the LAN port, and a web GUI accessible from any browser on the network. Additionally, CEC and RS-232 control allow the switcher to turn connected displays and external devices on or off. Bidirectional RS-232 and IR pass-through extend control to devices at the receiver end, enabling full room control from either the equipment location or the display wall without additional control system hardware.

Does the VLPT-51HT70 support automatic input switching?

Yes, the VLPT-51HT70 supports both manual and automatic input switching modes. In automatic mode, the switcher detects which inputs are active and selects the most recently connected source, making it well-suited for walk-up presentation spaces where users plug in and expect immediate output without pressing any buttons. Manual mode maintains the selected source until a user or control system explicitly changes it, which is preferred in managed AV environments with a room control system. Both modes are configurable via the web GUI, RS-232, or front-panel settings.
