Compact Scaler Switcher (with PoE)
7
receiver (bi-directional RS232 control, either is available).
Step7. Both the scaler switcher and the receiver have IR IN and OUT. When one model
is used for IR signal receiver, the other model must send out the IR signal.
For example: When “IR IN” of the scaler switcher connects with an IR receiver,
the IR transmitter must connect to IR OUT of the receiver.
The IR signal can be transmitted bi-directionally between the scaler
switcher and the receiver.
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 (the receiver is able to get
power from the scaler switcher).
3.4 Connection of Microphone
The compact scaler switcher provides one 3-level microphone input to accommodate
different microphone input modes, including 48V phantom power mode, MIC mode &
LINE mode.
Ø
48V phantom power input
When switched 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 microphones.
Connections: “+” connects to positive, “-” connects to negative and “
” to ground.
Ø
MIC input
When switched to “MIC” (It has a low frequency characteristics, and wide frequency
response in this mode), the microphone input is used for connecting dynamic
microphones. There are two different connections:
1) Unbalanced connection:
“+” and “
” connect to ground, and “-” connects to signal.
“-” and “
” connect to ground, and “+” connects to signal.
