3.3 Connection Procedure
Step1. Connect HDMI source devices (e.g. Blue-ray DVD) to HDMI input ports of TEK
51T-HD with HDMI cable. Connect VGA source device (e.g. PC) to VGA input
ports of TEK 51T-HD with VGA cable.
Step2. Connect the corresponding audio source to the corresponding AUDIO INPUT
port of TEK 51T-HD with audio cable one to one. The audio of HDMI can be
embedded or external by sending RS232 command.
Step3. Connect HDMI display device to HDMI output port of TEK 51T-HD with HDMI
cable.
Step4. Connect TEK TPHD402PR to HDBaseT output port of TEK 51T-HD with Cat 5e
or Cat 6 type cable.
Step5. Connect speaker, headphone, or amplifier to AUDIO OUTPUT port of TEK
51T-HD.
Step6. Connect control device (e.g. PC) to RS232 port of TEK 51T-HD or TEK
TPHD402PR (bi-directional RS232 control, either is available).

Step7. Both TEK 51T-HD and TEK TPHD402PR have IR IN and OUT. When one model
is used for IR signal receiver, the IR signal must be sent out by the other model.
For example: When “IR IN” of TEK 51T-HD connects with an IR receiver, the IR
transmitter must connect to IR OUT of TPHD402PR.
The IR signal can be transmitted bi-directionally between TEK 51T-HD and
TEK TPHD402PR.
Step8. Select MIC level and connect right microphone to MIC input port. MIC audio will
be transmitted to AUDIO OUTPUT port and mixed with source audio.
Step9. Connect DC12V power adaptor to the power port (TEK TPHD402PR is able to
get power from TEK 51T-HD).
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.

2) Balanced connection: “+” connects to positive, “-” connects to negative and “ ”
connects to ground.
LINE input
When switched to “LINE” (low frequency characteristics and wide frequency response in
this mode), the microphone input is used for connecting with line audio or wireless
microphone output. There are two different connections:
Unbalanced connection:
“+” and “ ” connect to ground, and “-” connects to signal.
“-” and “ ” connect to ground, and “+” connects to signal.
b) Balanced connection: “+” connects to positive, “-” connects to negative and “ ”

3.5 Application
The TEK 51T-HD is ideal for smaller system applications especially when there is no
need for an equipment rack. The switcher can be mounted under a conference table, on
a wall, or in a teacher’s desk. When used with a TEKVOX Drop-In system, a low cost
and complete mediated classroom system can be created.
4. System Operations
4.1 Operations of Buttons
