1.Microphone / Instrument Pre-Amplifier. Your FIREBOX is equipped with two
custom designed PreSonus microphone / instrument preamplifiers for use with all
types of microphones including Dynamics, Condensers, and Ribbons as well as
instruments and line level signals. The award winning PreSonus preamplifier design is
a Class A input buffer followed by a dual servo gain stage. This arrangement results in
ultra low noise and wide gain control allowing the FIREBOX user to boost desirable
signal without increasing unwanted background noise.
2. 48 Volt Phantom Power. The FIREBOX has selectable 48V Phantom power
available for both preamps.

+22dBu Headroom. The FIREBOX mic-pre has +22 dBu of headroom. This feature
gives you wide dynamic range and excellent transient response characteristics.
Neutrik Combo Connectors. Both preamps of the FIREBOX have a Mic/Line
connector using the Neutrik Combo connector. This revolutionary style connector lets
you use either ¼" phone or XLR connectors in the same female input.
INSTRUMENT INPUTS (Channels 1 and 2): The ¼" TS connector on channels 1
and 2 are for use with an instrument (guitar, bass, and etc.). When an instrument is
plugged into the instrument input, the microphone preamplifier is bypassed and the
FIREBOX becomes an active instrument preamplifier.
