The Io IP front panel has the following controls and indicators:
Monitor Output and Gain Control
A 1/8 inch TRS connector is available for monitoring two channels of audio,
selectable in channel pairs using the Control Panel application. Typically used
with a pair of headphones.
The Monitor Gain knob on the left adjusts the monitor output level. Pushing in
the knob extends it (for adjustment) or recesses it (to prevent accidental changes).
Audio Level Meters
The Audio Level Meters in the center of the front panel indicate:
• During Capture - The first 8 channels of the audio source selected (SDI, HDMI,
Analog)
• During Playback - The sum of whatever sources are being played out via
the AJA hardware; i.e. NLE timeline and mix of host system audio output (if
applicable)
The meter's LEDs are colored to indicate the amount below 0dBfs when averaged
over a one millisecond time interval:
