3.4. Connection of the Microphone
AVG-SC51D provides with one 3-level microphone input port, to accommodate
different microphone input modes, including 48V phantom power mode, MIC mode &
LINE mode.
48V phantom power input
48V phantom power input has a good frequency characteristic, high input impedance
and high sensitivity.
When switched to “48V”, the MIC input will provide 48V phantom power. This is only
used for condenser microphone.
Connect the microphone in this way: “+” connects to positive, “-” connects to
negative and “ ” to ground.
AVG-SC51D
MIC input
MIC input has low frequency characteristics, and wide frequency response.
When switched to “MIC”, the microphone input is used for connecting with dynamic
microphone. There are two different connection methods:
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.
AVG-SC51D
LINE input
LINE input has low frequency characteristics, and wide frequency response.
When switch to “LINE”, the microphone input is used for connecting with line audio
or wireless microphone output. There are two different connection methods:
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.
3.5. Application
AVG-SC51D has great application in various systems such as the IT realm,
monitoring, conference rooms, big screen displays, broadcast, education, command
& control centers and smart homes etc.
AVG-SC51D
4. System Operations
4.1. Operations of Front Panel Buttons
Front panel buttons can be used for output resolution adjusting, switching
operations, software updating, volume adjustment and other operations.
4.1.1. Resolution Adjusting
Resolution supports auto-adjusting and manual-adjusting. Press and hold for
RESO/AUTO button for 7 seconds or more to switch between auto-adjusting/
manual-adjusting mode.
Note:
1. In auto-adjusting mode, AVG-SC51D will choose the resolution of the display
device at the far-end as the preferred resolution.
If you need to choose the resolution of local HDMI display device:
Turn off the power of AVG-SC51D
Turn on the power of AVG-SC51D.
The unit grabs the resolution of the local HDMI output device.
2. In auto-switching mode, front panel button control is not available, but IR and
RS232 controls are able to switch modes.
4.1.2. Switching Operations
Video signals support auto-switching and manual-switching. Press and hold for
SOURCE/AUTO button for 7 seconds or more to enter in auto-switching/ manualswitching mode.
The display result is showed as below:
IN: HDMI1 MANUAL
IN: HDMI1 AUTO
1280 X 720
1280 X 720
The display result will be shown for 2 seconds.
AVG-SC51D
Auto-switching function
The auto-switching mode abides by the following principles:
New input principle
Once a new input signal is detected, AVG-SC51D will switch to the new signal
automatically.
Power rebooting principle
The AVG-SC51D offers a function to remember the last displayed signal when
rebooting. Once rebooted, AVG-SC51D will automatically enter auto-switching
mode, and then detect all inputs and memorize their connection status for future
rebooting use.
If the last displayed signal is still available, AVG-SC51D will output the signal. If not,
there will be no signal on output devices.
Signal removing principle
Once removing the current display signal, AVG-SC51D will detect all input
signals with priority from INPUT 1 to INPUT 5. It will transfer the signal detected
first to be available to all output devices.
Notice: The Auto-switching function works only when connecting a new signal,
removing a signal or power rebooting. With any VGA port set to AV or YPbPr, the
system will be not able to enter into Auto-switching mode.
Operation Examples:
Connect INPUT 2, INPUT 4, and INPUT 5 ports with source devices, select
INPUT 4 to outputs.
Press and hold for the front key SOURCE/AUTO for 7 seconds or more to enter
in auto-switching mode.
No signal removed or new input, AVG-SC51D just works in auto-switching mode,
and will take no action (Output from INPUT 4)
Connect INPUT 3 with a source device, and then it will choose INPUT 3 to
output.
Remove the signal of INPUT 3, AVG-SC51D will detect from INPUT 1 to INPUT
5. And when it detects that input 2 is available, it will choose INPUT 2 to output.
Cut off the power of the AVG-SC51D, then reboot. As the AVG-SC51D is in auto-
switching mode, it will choose INPUT 2 to output.
AVG-SC51D
4.1.3. Volume Adjustment
