2.0 Top Panel Features
INPUT LEVEL KNOBS
Turn these knobs clockwise to boost the input level as needed.
SIG/OL LED
This LED will light green when an input signal is detected, yellow when
a strong input signal is detected and red when too much input signal
is detected. A red LED doesn’t automatically mean your signal is clipping, but that it’s getting too close and it’s time to back off the level.
48V PHANTOM POWER
Pressing this button will send 48V through the XLR cable to power
a condenser mic. Always turn OFF the 48V when connecting and
disconnecting your microphone. When using ribbon microphones,
please refer to your mic’s documentation for proper use, since some
ribbon microphones may be damaged by phantom power.
–20DB PAD
Pressing the PAD button will lower the input signal by 20dB for use
with very loud sources.
75HZ HIGH PASS FILTER
Pressing this button will roll off frequencies below 75Hz.
COMP
Pressing this button engages the optical compressor. The yellow LED
will light brighter as more compression is applied to the input signal.
This compressor is designed to be very transparent for recording an
optimal level. Once recorded, you may want to experiment with more
aggressive compression, as needed within the context of your mix.
HEADPHONE
Turn this knob clockwise to boost the output volume of the headphones as needed.
NOTE: The IN2’s headphone amplifier is very high output, so always
turn the Headphone knob down before finding the right level.
