Gibson Firebird X - Low Battery Indications; Connecting to Amplification

Low Battery Indications
Depending on how often you tune, the battery charge can last up to two hours of
continuous playing. The following indicators represent the battery status.
 Gear Shift knob has green dot in center: Battery is charged, with at least 30
minutes charge remaining
 Gear Shift knob flashes yellow: 10 to 30 minutes of charge left
 Gear Shift knob flashes red: Less than 10 minutes left—replace battery. Low-level
white noise appears in the output to give audible confirmation of battery status.
 Gear Shift knob flashes blue approximately every four seconds: After 10 minutes
without activity, Firebird X goes into “sleep” mode. (Sleep mode still drains the
battery somewhat; to prevent this, turn the guitar off completely.) Move the Gear
Shift knob to “wake up” Firebird X.
Connecting to Amplification
Firebird X’s unbalanced output can drive anything from a guitar amp, to a mixing board’s
low-impedance input, to a computer’s audio interface. Separate cables are included to
connect Firebird X to either 1/4” phone jacks (balanced or unbalanced, with ring not
connected) or XLR inputs (pin 2 hot, pin 1 ground, and pin 3 not connected). Note: Use only
the supplied stereo cable to connect Firebird X to the G-Node interface.
Caution! When patching Firebird X to a balanced XLR input, make sure the XLR input
does not have phantom power enabled. This could damage Firebird X’s output.
Firebird X’s output level is somewhat “hotter” than standard guitars. Start with the
amplifier volume at minimum, then turn up to a comfortable listening level. Note: Firebird
X produces no “thump” on power-up or power-down, so you may safely turn Firebird X on
or off even if your amp is set to high levels.
For a quick audio check, you can plug standard headphones directly into Firebird X’s
output. However levels will be low, and only in the left earphone.
