The VSA-X21 is an award winning HDBaseT Receiver with 50watt audio amp. It includes a flexible embedded WebGUI that can be used to select inputs, control volume, turn the display power on/off, and more. VSA-X21 can directly drive 8 ohm speakers and is compatible with any HDBaseT compliant sender such as the UHBX-S-WP wall plate HDMI sender, or the UHBX-SW3-S sender with multiple HDMI and VGA inputs. "Long-Reach" mode allows Cat6 cable lengths to 150 meters.

For mixing audio from other audio sources such as microphones, a separate audio input is provided.

It can also control other devices such as projectors via RS232 or LAN. A configurable WebGUI is embedded that lets users create, name and assign functions to virtual buttons on a control page. It also supports connection to physical keypad VSA-UI-DP for control.

Advanced features include: auto display On/Off control, auto input selection, priority page mute, HDMI audio ducking, L/R stereo to mono mixer, and ARC audio support.

For mounting under a desk on in a projector vault, a pair of brackets (F10341-KIT) are included with the product. The brackets can be mounted two ways, with the "L" flange pointing outward or tucked under the device (for tight spaces)
