Turning +48V phantom power on/off
1.
Press [+48V] to turn +48V phantom power on/off.
If +48V phantom power is on, the [+48V] button will light.
You must turn the phantom power off if you’ve connected
equipment that does not require +48V phantom power.
Mistakenly supplying phantom power to a dynamic
microphone, audio playback device, or any other device that
does not require phantom power will cause malfunctions.
Carefully read the owner’s manual for your microphone or
other device, and make sure of its specifications.
Since noise will be produced when you switch the phantom
power setting, the output of the channel whose setting you
change will be briefly muted.
Adjusting the preamp gain
1.
Use the GAIN dial to adjust the preamp gain.
The preamp gain is not a continuous control, it is digital with
stepped control. In certain situations artifact noise may occur
when changing preamp gain.
Turning -20 dB pad on/off

Press [PAD] to turn pad on/off.

briefly muted.
Turn the pad on if the input level is too high even when the preamp
gain is set to the minimum position.
