3.4 Connection of Microphone
TEK 51T-HD provides one 3-level microphone input to accommodate different
microphone input modes, including 48V phantom power mode, MIC mode, and LINE
mode.
48V phantom power input
When switched to “48V”, the MIC input provides 48V phantom power. This is only used
for the condenser microphone.
Connection is: “+” connects to positive, “-” connects to negative and “ ” to ground.
MIC input
When switched to “MIC” (low frequency characteristics and wide frequency response in
this mode), the microphone input is used for connecting with the dynamic microphone.
There are two different connections:
1) Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-” and “ ” connect to ground, and “+” connects to signal.

Switching Operations
4.1.2
The TEK 51T-HD Supports both auto-switching and manual switching. Press and hold
the SOURCE/AUTO button for 7 seconds or more to enter into
auto-switching/manual-switching mode.
The display result is showed as below:
The display result will be shown for 2 seconds.
The auto-switching mode follows the listed principles:
New input principle
Once it detects a new input signal, the TEK 51T-HD switches to this new signal
automatically.
Power rebooting principle
TEK 51T-HD offers this feature to remember the last displayed signal when
rebooting. While rebooting, the TEK 51T-HD automatically enters into auto-switching
mode and detects all inputs to memorize their connection status.
If the signal last displayed is still available, then it will choose the signal to output. If
not, there will be no signal on its outputs.
Signal removing principle
Once it has removed the current display signal, the TEK 51T-HD will detect all input
signals with priority from INPUT 1 to INPUT 5. It will select the first detected signal to
its output.
Notice: The Auto-switching function works only when an input detects a new signal, loss
of a signal, or power rebooting. With any VGA port set to AV or YPbPr the system is not
able to enter in Auto-switching mode.

7. Troubleshooting & Maintenance
1) When the output image is looks like noise or snowflakes, common problems
include but are not limited to:
Poor quality cable. Please try another higher quality cable.
The video cables are loose. Try reconnecting them.
2) When it is not able to manage EDID, the HDMI cable may be broken or
loose.
3) When a user cannot control the switcher by computer through its COM port,
check the COM port number in the software and make sure the COM port is
in good condition.
4) If the POWER indicator doesn’t work or respond to any operation, ensure
the power cord’s connection is secure.
5) No output image when switching:
Use an oscilloscope or multi-meter to determine if there is a signal at the
input and output end. If there is no signal, the connection cord may be
broken or have loose connections. Use a new cable and/or attempt to
reconnect them.
If none of these methods have worked, there may be something wrong
with the switcher. Contact your dealer if this is the case.
6) If the static becomes stronger when connecting the video/audio connectors,
the grounding may be incorrect. If it is incorrect, the connection may
damage the switcher.
7) If it is not able to control the scaler-switcher from front panel buttons, but
able through RS232 commands, the front panel buttons are probably locked.
Send command 50605% to unlock.
8) If the scaler-switcher cannot be controlled by the buttons on the front panel,
RS232 port, or IR remote, the switcher may be broken. Send it to the dealer
for repairs.

3) Since the unit produces some heat, the working environment should be
maintained with ventilation
4) Cut off the general power switch in humid weather or if it is left unused for a
long period of time.
5) Before following operation, ensure that the alternating current wire is pulled
out of the power supply:
Take off or reship any components of the equipment.
Take off or rejoin any pin or other link of the equipment.
6) Unless you are a professional or given permission, DO NOT try to open the
