User's Manual

If you look at the front panel above the main source buttons you can see that each source
button has a small audio meter plus an ON and AFV button. These buttons above the source
buttons are the audio controls for that specific input. If you want to control the audio settings for
input 1, then you use the controls immediately above input 1. It’s the same for each of the other
inputs to the switcher and the controls for each input are above the input source button.
You can also change audio settings in the LCD menus as there is a full menu just for audio
settings, proving an alternative way of adjusting audio. Of course, any control you do on the
front panel and in the LCD menus is also reflected in the software control panel. You can try
connecting a computer, selecting the audio mixer in the software control panel and watching
the effect of each front panel setting on the audio mixer. This can be a good way of better
understanding what the front panel audio controls are doing.
Audio Control
To turn audio for this input on permanently, simply press the ON button above its source button.
Now the audio from that input will be sent to the built in audio mixer and be heard on the
program output.
To select audio only when the input is on air, select the AFV button. This means audio follows
video and the input is now only on when the source is on air.
Audio Levels
The function of the knob on the front panel is primarily for audio level adjustment, although it is
used for menu selection when you are in the LCD menus. However, normally it’s used for audio
level control, and you can tell what it’s controlling by looking at the LCD. The label on the LCD
will tell you what the knob is adjusting.
Normally, the LCD has the label Master and this means the knob is adjusting the main audio
mixer master output. Adjusting the knob will lower the whole program audio levels and
you can see the effect on the main audio meters in the LCD that are superimposed on the
video preview.
Use the knob to adjust the master audio level and you
can see the effect on the main audio meters in the LCD
If you want to adjust the audio for one of the inputs, this is where the small 4 LED meter above
the source button is used. This small meter lets you identify where a hot audio level could be
coming from. If the main audio level is too high and only one of the small meters on the front
panel has a red flashing LED then this means that only that single input is too high level.
So in this case you don’t want to adjust the master audio level because all the other inputs will
now become too low. You really want to select the input audio level and adjust just that single
audio level.
