¼-inch Phones (headphone) Jack. This is where you connect headphones to your
AudioBox USB.
Main Out. These are the main outputs for the AudioBox USB. The output level of the
Main Outs is controlled by the Main volume knob on the front of the unit.
Power User Tip: You must connect speakers or headphones directly to your AudioBox USB in order
to monitor playback from your computer.
MIDI I/O. MIDI stands for “Musical Instrument Digital Interface.” MIDI inputs
and outputs allow connection to, and communication with, external MIDI
equipment. One function of these ports is MIDI sequencing but the MIDI
protocol can be used for much more than instruments and sequencing.
NOTE: MIDI is not audio but is frequently used to trigger or control
an audio source (such as a plug-in or synthesizer). It’s important
to ensure that your MIDI data is correctly sent and received by
the appropriate hardware or software devices. If the devices
generate audio, you may also need to return the audio to an
AudioBox USB input channel. Please consult the User’s Manuals
of your MIDI devices for help with MIDI setup and usage.
USB Port. This is where you connect the USB cable from your AudioBox USB to your
computer. The AudioBox USB is bus-powered via this connection and does not
require an external power supply.
Your AudioBox USB is compatible with all types of USB ports (1.1, 2.0, and 3.0).
