To adjust audio volume complete these steps in the VGA Grid HD Encoder's Admin panel (note this is done on the encoder, and not the VGA Grid):

1. Ensure an audio input source is connected to an analog audio input port.
2. Connect to the VGA Grid HD Encoder's Admin panel using your preferred connection method. See Connect to the Admin panel and log in as admin.
3. From the Admin panel, scroll to the Configuration section.
4. Click Audio; the following window opens.

5. Choose Line to capture high-powered audio signals from self-powered equipment, such as a CD player, synth or amp, or select Mic to capture audio from a microphone connected to the audio input port.

Adjusting the Input Amplifier adjusts audio levels in both the recorded and streamed output.

6. If using a microphone or other source that needs an audio boost, enable Microphone 20dB boost to provide additional volume amplification for the microphone inputs.
7. Click Apply.
