Microphone / Instrument
Inputs. Each input channel has both
a microphone and an instrument
preamplifier. The combo connectors
allow you to use either a ¼” TS
or the included XLR cables. Use
the ¼” connection for guitars and
other unamplified instruments.
Use the XLR connections to
connect your M7 microphone.
48V Phantom Power. This
button activates phantom power
for both microphone preamps.
Power User Tip: Condenser
microphones, like the M7 microphone
included in your Music Creation Suite
require +48V phantom power to
operate. When using microphones
other than the one included in this
bundle, review the manufacturer’s
documentation to verify that
phantom power is required and will
not damage the microphone.
Power LED. This LED indicates
bus power. It will illuminate red
when the AudioBox USB is being
properly powered by the USB
connection on your computer.
Main Level. This knob controls
the output level for the Main
Outs on the back of the unit.
Mixer. The knob blends the analog
input signals with the playback
signal from your computer. This
allows you to monitor your input
signal with zero latency. If the knob
is positioned at 12 o’clock, the input
signal and the playback stream will
be equally balanced. Turning the
knob to the left will increase the
level of the input signal relative to
the playback stream; turning it right
will increase the level of the playback
stream relative to the input signal.
Power User Tip: In most instances
you will set the Mixer knob to
Inputs while you are recording and
Playback when you are listening to
your recordings in Studio One.
Phones Level. This knob controls
the output level for the headphone
connection on the back of the unit.
Input Gain/Trim Control.
These knobs adjust the input gain
level for their respective inputs.
Clip Indicator. Both channels feature
a clip LED next to each trim control.
This light will illuminate red when the
channel’s input signal reaches 0 dBFS.
Power User Tip: Never run your input
levels higher than the channel inputs can
handle. If you overdrive the analog-to-
digital converters, it will cause digital
distortion, which sounds terrible and will
ruin an otherwise wonderful recording.
Always set your input levels so that the
clip light rarely, if ever, comes on. It’s
important to remember that you can
usually increase the level of a recording
that is too quiet, but once a recording
is clipped, there is no way to undo it.
