AUDIO SIGNAL CONNECTION
Please use the special five core RGB signal cord to connect the input and output devices and connect the BNC
connector R (red) G (green) B (blue) H (horizontal) V (vertical) carefully.
Attention:
Please make sure the RGBHV connectors from the sources and to the destination should be in the same
Order, Otherwise it could cause color loss or no output signal at all. Use supplied BNC to RCA for Component.
“AUDIO INPUTS”, “AUDIO OUTPUTS” audio network interface in RGB matrix switchers can be connected to
the audio signal and amplify sources. The audio connection is a little more complicated than video. It has two
types of connection: balanced and unbalanced. The balanced connection transmits a pair of balanced signals
with two cables. Because interferences will have the same intensity and the opposite phases on the two cables;
it will be counteracted in the end. For the low frequency extent of the audio signal, it would be easily interfered
under long distance transmission. Therefore as an anti-interference connection, it is mostly used in the connec-
tion of special high end devices.
The unbalanced connection transmits signals with only one cable. Without counteraction, it can be interfered
more easily. Accordingly, it is adopted for household appliances or some cases with low technical demand.
Take the audio signal line for example: 1.Unbalanced: pin “G” connects to SLEEVE, pin “+” connects to TIP,
pin “–” connects to pin “G”; 2.Balanced: pin “G” connects to SLEEVE, pin “–” connects to RING, pin “+”
connects to TIP.
To select which connection is up to the interface of the device. When available, the balanced connection is the
first choice. Before connection, please read the command or relevant demand in the user manual carefully. In
some cases, there is balanced in the source signal end but unbalanced in the destination end. If in a nonstand-
ard case, it is done to connect balanced for the balanced end and unbalanced for the unbalanced end. But if in
a standard one, the converter must be used to switch the signals as the same,balanced or unbalanced.
