IR signal receiver, the IR signal must be sent out by the other model.
For example: When “IR IN” of SC51T connects with an IR receiver, the IR
transmitter must connect to IR OUT of TPHD402PR.
The IR signal can be transmitted bi-directionally between SC51T and
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 (TPHD402PR is able to get
power from SC51T).
3.4 Connection of Microphone
SC51T provides with one 3-level microphone input, to accommodate different
microphone input modes, including 48V phantom power mode, MIC mode & LINE mode.
 48V phantom power input
When switch to “48V” (It has a good frequency characteristic, high input impedance and
high sensitivity in this mode), the MIC input will provide a 48V phantom power. This is
only used for condenser microphone.
Connection is: “+” connects to positive, “-” connects to negative and “ ” to ground.
 MIC input
When switch to “MIC” (It has a low frequency characteristics, and wide frequency
response in this mode), the microphone input is used for connecting with 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.
