FRONT PANEL DESCRIPTION
1. Power LED Indicator
When you connect the DC power converter and
change the power switch to the DC IN (or BUS,
if using the 6-pin FireWire connector) position,
the unit will be powered and the front power
LED will be illuminated giving you an indication
that your Firefly is on and running.
2. Headphone Output Jack and Control
All the audio signals that are mixed on computer
can be monitored with the Headphone output.
You can also control this level with the
corresponding level control.
3. XLR Microphone Connector
This is a balanced microphone XLR 3-pin
connector, which you can use to connect
dynamic or condenser microphones. Phantom
power may be applied to these connectors to
allow all condenser or ribbon microphones to
be connected.
4. Mic Gain
Turn this knob clockwise to increase the
Microphone input's gain. You have 44dB of
possible gain with this knob, so please take
care when applying gain to ensure Mic Clip
LED does not light up.
5. Gain 1 and 2
This knob controls the input gain for the RCA
and 1/4" plug input jacks located on the rear
panel. Turn then clockwise to increase the
signal level gain or turn them counterclockwise
to lower the input levels. Gain 1 controls the
Analog In RCA 1 and 1/4" TRS 1 input jacks,

and Gain 2 controls the Analog In RCA 2 and
1/4" TRS 2 input jacks. Each gain control is
independent so you can easily match your
input levels.
6. +48V Phantom Power
Pushing this button will activate +48V of phantom
power on the microphone input, allowing users
to connect condenser microphones, ribbon
microphones, or devices that need +48V power
to work properly. If you are not sure if your mic
requires phantom power, please refer to the
microphone's owner's manual.
7. Sig / Clip Indicators
These LED indicators give users an idea
of when their analog and mic inputs and
outputs are receiving a signal (sig) and when
that signal reaches high peaks just prior to
the signal being dynamically clipped, which
may cause undesirable effects to your audio
integrity (clip).
