Front-Panel Connections and Controls

1) Microphone/Instrument Inputs: Both channels of the IUSB400 have Mic/Instrument combo jacks. This
convenient connector accepts either a ¼-inch phone plug or an XLR plug.
The XLR inputs on channels 1 and 2 are equipped with two microphone preamplifiers. These preamps
work great with all types of microphones including dynamic, ribbon, and condenser microphones.
Power User Tip: Dynamic microphones and ribbon microphones (which are a special type of dynamic mic) are generally
lower-output devices that, with few exceptions, require no external power source. Sending phantom power to a ribbon
mic that does not require it can cause severe damage to the mic – usually beyond repair. Condenser microphones are
generally more sensitive than dynamic and ribbon microphones and typically require external +48V phantom power.
Always review your microphone's documentation and follow its recommended operating practices.
The ¼-inch TS connectors on channels 1 and 2 are for use with instruments (guitar, bass, etc.).
Power User Tip: Active instruments are those that have an internal preamp or a line-level output. Active instruments
should be plugged into a D.I. box, which should then be connected to the mic input rather than directly to an instrument
input. Plugging a line-level source into the instrument inputs on the front of the IUSB400 not only risks damage to
these inputs but can also result in a very loud and often distorted audio signal.
