1. Product Introduction
The TekFlex-85T Pro is an 8x5 presentation matrix switcher designed to simplify the
implementation of large distance learning and HyFlex systems. The TekFlex-85T Pro
includes dual HDBaseT outputs for multi-display systems, a quad-multiview camera switcher
with USB capture, and seven HDMI inputs & 1 USB-C input with 60W charging. Matrix
switching ensures that any input can be routed to any output, and the switcher includes
twelve flexible multiview configurations for displaying up to four sources at once, as well as
an auto-switching mode.
The built-in, multi-host USB 3.0 KVM BYOM from an in-room PC, 2 separate HDMI laptops,
and a USB-C laptop. The TekFlex-85T Pro also includes an internal DSP with four microphone
inputs (each with toggleable phantom power) for mixing microphones, providing speech
reinforcement, echo cancellation, and AEC reference for ceiling microphones. Finally, the
TekFlex-85T Pro includes a PoE-capable internal network switch, which drastically reduces
the number of network connections needed for larger systems. The camera multiviewer
supports Side-by-Side (SBS) and Picture-in-Picture (PIP) usage of system cameras for
conferencing. The internal network switch reduces network drops needed, and supports PoE
for powering a connected controller or touchscreen.
With an incredible array of advanced features packed into a 1RU form factor, the TekFlex-85T
Pro represents the pinnacle of comprehensive, integrated A/V for distance learning and
HyFlex systems.

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) will turn blue
When switching to two-window (A&B) mode, the corresponding mode
LED will turn blue, and the window A and B LEDs 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
4.2 Full-Screen Setting
The factory default mode is Full-Screen, and the correspondence is:
Input 1 →Window A.
In Multiview mode, press the Window A~D buttons to select the
corresponding window to display in full screen. The corresponding
input source button LED and window button A LED illuminate blue,
and other window buttons and previous Multiview mode button
LEDs will go out.
4.3 Audio Control
By default, the HDMI and HDBT output audio follows the video
source in Full-Screen mode, but in the Multiview modes
there will be no output audio. The audio source can be
changed via GUI or RS232 commands.
Press the volume knob to select Source level or Speech level.
Rotate the knob to increase or decrease the volume of the
selected audio. Press and hold the knob for at least 3 seconds to mute the selected audio; rotate
