1. Product Introduction
The product is a professional 6x2 4K presentation switcher kit consists of a switcher
and an HDBaseT Receiver.
The switcher is a 6 input multi-format (3 HDMI, 2 VGA, and 1 DP) 4K presentation
switcher that switches video signals to an HDMI and an HDBaseT output. The
HDBaseT output supports PoH and can connect to compatible HDBaseT receiver up to
a maximum of 70 meters (230 feet).
The switcher supports video resolutions up to UHD (4Kx2K@30Hz 4:4:4). With multiple
built-in EDID settings, including an EDID pass-through option, the highest quality digital
video signal will be routed directly to the display. When a VGA video signal is
connected, the video signal will be scaled up to 1920x1200.
The switcher supports stereo and multichannel audio on the HDMI/DP inputs. The
analog audio paired with the VGA inputs is embedded into the digital video stream. In
addition to the audio embedded in the HDMI and HDBT output stream, which may be
muted, the audio is simultaneously de-embedded to an amplifier, a digital optical audio
output, and four analog audio outputs: two 3-pin phoenix connectors, a 3.5mm mini-
jack, and a 5-pin phoenix connector.
The switcher features multiple methods of control. When set to Auto, the switcher will
automatically switch to the newest source device added to the switcher; when the
active source is removed, the switcher will switch to the first detected input. The
switcher can be manually controlled via front panel, IR, RS232, and GUI.
1.1 Features
The transmission distance between the switcher and HDBaseT receiver can up to
70m at 1080p, and 40m at 4K video.
Supports auto-switching.
HDMI input supports 4Kx2K@30Hz 4:4:4, HDCP2.2.
VGA video resolution can be selected as 1024x768, 1280x720, 1280x800,
1360x768, 1920x1080 or 1920x1200.
The MIC and LINE input can be mixed with audio outputs.
3-type microphone input, supports condenser microphone, dynamic microphone,
and wireless microphone.
Supports audio matrix: 1 MIC input, 1 LINE input,1 HDMI embedded audio input, 1
HDBT embedded input, 2 unbalanced audio outputs (3-pin phoenix connectors), 1
balanced/unbalanced audio output (3-pin phoenix connector), 1 analog stereo audio
output (3.5mm mini-jack), 1 digital optical audio output (SPDF) and 1 2x20 watt@4Ω

amplifier. The balanced/unbalanced audio output, analog stereo audio output, and
digital optical audio output come from the same input audio.
Supports embedded EDID selection and customized EDID.
Supports 48V PoH for simplified wiring.
Controllable via front panel buttons, IR Remote, RS232 & GUI.
Supports online software upgrading.

5. Button Control
The front panel buttons can be used for signal switching, VGA resolution, volume
adjustment.
5.1 Manual Signal Switching
First press any one of six inputs button, second press either 1-HDMI or 2-HDBT output
button, and finally press ENTER to select. The following are two examples:
1) Switch 2-HDMI input to 1-HDMI output:
2) Switch 5-VGA input to 2-HDBT output:
5.2 Auto Signal Switching
Press AUTO,and then press the output 1-HDMI to enable the HDMI output port to
automatically switch its input channel. Press them again to disable this auto mode.
Press AUTO,and then press the output 2-HDBT to enable the HDBT output port to
automatically switch its input channel. Press them again to disable this auto mode.
For example: Enable auto-switching mode for 1-HDMI output:
The auto-switching mode abides by the following principles:
New input
Once detecting a new input signal, the switcher would switch to this new signal
automatically.
Rebooting device
The switcher can save the last configuration before losing power. If the last
switching mode is auto-switching, once rebooted, the switcher will automatically
enter auto-switching mode, then detect all inputs and memorize their connection

status for future rebooting using. If the last displayed signal is still available, the unit
will output the signal. If not, the unit will detect all the input signals with priority from
1-HDMI to 6-VGA. When detected the first signal, will transfer to output.
Signal removing
Once removing the current display signal, the switcher will detect all input signals
with priority from 1-HDMI to 6-VGA. It will transfer the signal firstly detected to be
available to output devices.
5.3 VGA Scaling Resolution Selection
Press 5-VGA/6-VGA to set its output resolution, press again to select next one
(1024x768, 1280x720, 1280x800, 1360x768, 1920x1080, or 1920x1200).
5.4 Volume Adjustment
Press MIC+ or MIC-to increase or decrease microphone volume.
Press VOL+ or VOL-to simultaneously increase or decrease the volume of all audio
outputs.
