To set the Audio Gain:
1. Channel 1 will be the only channel available in the drop-down list unless you have a mono-
configured AudioFetch Express, in which case Channel 1 and Channel 2 will be available.
2. Ensure an audio source is connected to the AudioFetch Express.
3. Monitor the Peak Audio Status number, if an active audio source is connected then it will
constantly change.
a.
NOTE:
Doghouse Channels Setup page
b.
If the Audio Gain setting is very low (a large negative number) then this might be the
problem – try changing the Audio Gain setting to a number like 15 (positive fifteen)
c.
If it remains at 0% then check if enabled in the Channels Setup page, check the audio
connections, else something is likely wrong in the cabling or audio source
4. Optimum Peak Audio Status is when the status hits 70% to 95% at its maximum
5. If Peak Audio Status is too low or too high, enter a new value for Audio Gain. Values
entered can be numbers like 7 or 9.0 or 12.5 (the tenths digit can only be "0" or "5").
Acceptable range is -100.0 to 20.0.
set/save the new gain value.
a.
After saving, you should notice a corresponding change in the Peak Audio Status
level immediately
b.
Keep adjusting the Audio Gain until Peak Audio Status is within optimum range
6. Repeat this procedure for all audio channels
The example presented above shows an Audio Gain setting of 15.5 and resulting Peak Audio Status of
84.3% (this will change continuously).
MICROPHONE INPUT:
The AudioFetch Express Analog Input connector normally accepts a 3.5mm stereo plug with line-level
stereo signal. By checking the "Microphone Enable" box in the AUDIO GAIN section,
Input is reconfigured to accept a condenser style microphone and provide 4.7V (through 3.9K resistor)
phantom power to the microphone.
The microphone used must be a type compatible with standard PC sound card mic input,
powering requirements compatible with the 4.7V phantom power (through 3.9K resistor) provided by
the AudioFetch Express. AudioFetch recommends the Pyle PLM31 Cardioid Condenser Headset
microphone, readily available through many online retailers. Some less expensive microphones
available online do not work very well with issues such as low output, distortion, etc.
There will be no status indicated if the selected channel is not enabled in
