Microphone audio input configuration
There are two mic/line inputs for the IN1606 and IN1608 series. The Mic/Line Input tab
contains options to apply phantom power or a high pass filter to the microphone inputs, set
ducking parameters, or adjust input gain on the microphone inputs.

Phantom power
Phantom power adds +48 VDC to the mic/line input. The default level for the microphone
input is 0 dB, muted. Having the input muted before plugging in a microphone and
especially before turning on phantom power is recommended.
ATTENTION:
• Condenser microphones require +48 V phantom power. Dynamic microphones
do not require power. Never enable phantom power with an unbalanced dynamic
microphone connected. Doing so may damage the microphone.
• For condenser microphones, verify it will safely operate at +48 VDC.
• When a line level source is connected, be certain the +48 V phantom power is
disabled.
To enable or disable phantom power:
1. Click the Mic/Line Input tab.
2. In the Mic/Line input panel for the desired microphone input, click the Phantom Power
button. The button turns blue when enabled.
