•
¼" Headphone Jack. This is where you connect your headphones to the AudioBox USB.
•
Main Output. This is the main output for your AudioBox USB. The output level of the Main
Outputs is controlled by the AudioBox USB Main volume knob on the front of the unit.
•
MIDI In and Out Ports. MIDI stands for "Musical Instrument Digital Interface". However,
the MIDI standard goes well beyond just instrumentation and sequencing. The MIDI inputs
and outputs allow connection and/or communication with external MIDI equipment. One
function of this port is MIDI programming. These can also be used for MMC (MIDI Machine
Control) and MTC (MIDI Time Code).
NOTE: MIDI is not audio but is frequently used to trigger or control an audio source (such as
a VST plugin or synthesizer). When using MIDI, ensure your MIDI data is correctly
sent and received by the appropriate hardware or software instruments. You may also
need to return those devices' audio to the AudioBox USB. Please consult the User's
Manual 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 is completely bus powered from this connection.
