VSA-X21
Audio Functional Block Diagram

The VSA-X21 can directly drive 8-ohm speakers and is compatible with any HDBaseT compliant sender such as the model UHBX-S-WP wall plate HDMI sender, or the UHBX-SW3-WP sender with multiple HDMI and VGA inputs. The VSA-X21 provides power to the senders using PoH eliminating the need to connect power to the senders. It also employs “Long-Reach” mode allowing Cat6 cable lengths to 150 meters.

For mixing audio from microphones or other sources, a separate audio input is included. When connected to a network, control is possible via LAN either using Telnet, or using the internal WebGUI. The flexible WebGUI lets users create, name and assign functions to virtual buttons.

A keypad port is also included for connecting an X21-UI remote control wall plate when physical control of the room with a real keypad is required.

Other advanced features include priority page mute, ducking, auto input priority, L/R to mono mixer, and ARC audio support.
