1. Product Introduction
The 1201-MV is a universal switcher that supports 4Kx2K@60Hz 4:4:4, flexible multiview modes, and
six video inputs: five HDMI, and one powered USB-C. The 1201-MV includes simultaneous HDMI &
HDBaseT outputs, LAN bridge extension, and a simulated USB 3.0 hub extender with bridging to the
USB-C input. The HDMI output can be configured to mirror the HDBaseT output or preview the HDMI
1 input. The HDBaseT output can travel up to 328 feet (100m) without any additional amplification,
and supports PoC for remotely powering the receiver.
The 1201-MV also features automatic source detection & switching, can power displays on and off
using CEC or RS232, and offers versatile multiview for showing up to four sources on-screen
simultaneously. The universal switcher can extend USB signals—such as cameras and
microphones—from the far-end hub, making them available to the system PC or a connected laptop.
The 1201-MV is available with or without its hub/receiver.

There are four built-in Multiview modes which can be selected via the
front panel buttons.
Input 1 -> Window A
Input 2 -> Window B
Input 3 -> Window C
Input 4 -> Window D.
The view buttons’LEDs (A~D) turn blue
When switching to two-window (A&B) mode, the corresponding
mode’s LED will turn blue, and the window A and B LEDs will turn
blue. The factory default correspondence between the two input
sources and the two output windows is:
Input 1 -> Window A
Input 2 -> Window B

79033-MV User Manual
4.2 Fullscreen Setting
The default mode is fullscreen, and the default routing is:
Input 1 -> Window A.
In Multiview mode, press the Window A~D buttons to display the
corresponding window in full-screen mode. The corresponding
input source button LED and window button A LED will illuminate
blue, and other window buttons and previous Multiview mode
button LED will go out.
4.3 HDMI Output Settings
MIRROR: Press to set the local HDMI output as an HDBaseT loop
output, meaning that the HDMI and HDBaseT ports will
simultaneously output the same signal source.
BYPASS HDMI 1: Press to set the HDMI output port to output the
source signal of HDMI input 1.
4.4 Audio Control
By default, the HDMI and HDBT output audio follows the video
source in Fullscreen Mode. In the Multiview modes, the output
audio will come from the HDMI 1 input. The audio source can be
changed via GUI or RS232 command.
Press the volume knob to select MIC or SOURCE audio. If MIC
audio is selected, then the MIX and MIC mixing audio inputs are
controlled simultaneously.

4.5 Video Signal Switching
In Multiview modes
Operation: Input # + Window #
Example: Switch Input 1 to Window B:
Press “Input 1”(The input 1 LED will turn blue, and the A~D LEDs will flash.) Press “Window B”
(The A, C, and D LEDs will go out, and then the input 1 and Window B LEDs will flash three times. The
input 1 LED will then go out, and the A~D LEDs will turn blue.)
In Fullscreen Mode
1. Manual Switching
Operation: Directly press Input #
If Input 2 is currently set to fullscreen Window A, press “Input 3”to switch HDMI Input 3 to Window
A. The Input 3 and Window A LEDs will then turn blue.
2. Auto Switching
Press the “AUTO”button to enable or disable auto-switching mode. Note that auto-switching mode
only works while in Fullscreen Mode. When in auto mode, the switcher will switch according to the
following rules:
⚫The switcher will switch to the available active inputs with the following priority: Input 1 > Input
2 > Input 3 > Input 4 > Input 5 > Input 6 (USB-C). When the input source and output window are
connected, the corresponding LEDs will turn blue.
⚫New input: The switcher will automatically select a new input once it has been detected.
⚫Reboot: If power is restored to the switcher, it will automatically reconnect to the input that
was active when the switcher powered off.
⚫In auto-switching mode, the input source can be switched manually, but doing so will exit auto-
switching mode
⚫When changing from Fullscreen Mode to Multiview mode, auto-switching mode will not exit.
4.6 Switching Status
In Multiview mode, the LEDs for Windows A, B, C, and D will turn blue
Operation: Press and hold Window # button for at least 3 seconds.
Example: To determine which source is being sent to Window B, press and hold the Window B button
for at least 3 seconds. Windows A, C, and D’s LEDs will turn off, and the LED of the input being sent
to Window B will light up (e.g. if Window B is currently set to Input 2, the Input 2 LED will light up).
After 3 seconds, the Window A, B, C, and D LEDs will turn back on, and the Input 2 LED will turn off.
