Product Features

  • Everything you need is in one kit—including collaboration system, presentation switcher, a control panel, and even cables.
  • Easy to set up and use for a small meeting room where typically up to ten people meet to share ideas.
  • Keep the focus on collaboration and productivity, not equipment management.


Today's workplaces need to support easy-to-use technology so the focus can be on collaboration and productivity rather than managing equipment. This kit, designed for a small meeting space, contains everything you need to create a modern conference room with integrated collaboration, video and control systems. The system is pre-configured and ready to use for most conference rooms. No programming knowledge is required.

Coalesce Professional

With Black Box's wireless collaboration and videoconferencing system, Coalesce Professional, everyone's ideas are just a few clicks away. It enables up to four users to share content from any device, PC, laptop, tablet, or iOS or Android device, to the display. Using an optional touch screen even allows users to collaborate directly from the screens. Each connected user can share an unlimited number of items simultaneously. Share desktop, apps, docs, images and videos in real time.

Coalesce connections can be over a wired or wireless network, or even using two networks at the same time, so guest users can share ideas too. The compact form factor is easy to deploy behind flat panels and above projectors. Coalesce is compatible with virtually any display, including touch screens, via an HDMI connection. Learn more at

4x1 Presentation Switcher

To address multi-use rooms with multiple video inputs, use the 4x1 Presentation Switcher. It's the center of your system and enables you to connect, extend, and switch four inputs to any conference room display. It switches fast and seamlessly between any of the standard video formats (DisplayPort, HDMI, DVI with adapters), and VGA. There are no worries about 4K video either. The switcher up- or down-scales 4K video to match the display resolution. The switcher fits beneath conference tables or neatly in lecterns.

8-Button Wallplate Control Panel

Use this sleek wall-plate-based control panel to operate and control the Presentation Switcher, other AV or KVM switchers, and other AV devices with RS-232, RS-485, IR, or relay control. The control panel is pre-programmed and enables users to select sources, turn the display on or off via CEC, or to mute audio, but can be modified for other application specific requirements. Each of the eight buttons is fully programmable.


The kit includes the cables you need to connect everything to the 4x1 Presentation Switcher and to your network. See the Application Diagram under Support for more details.
