3. Channel 1 and 2 Inputs
These two combo jacks allow users to connect either balanced
XLR -pin connectors, for dynamic or condenser microphones,
or ¼" TRS phone jacks for instruments such as electric or bass
guitars.
NOTE: When plugging line-level signals into the combo jacks, disengage
the PAD button to lower the signal level to an acceptable degree.
4. Input Gain Controls 1 - 8
Turn these knobs clockwise to increase the microphone/line
input gain for the corresponding channels. You have 50dB of
gain to work with, but be sure not to adjust it to a level that will
make the input meter hit the "clip" point. A good region to be
in is about -6dB – this will give you a greater signal level with
enough headroom to avoid clipping.
5. PAD selector
This button controls the input sensitivity for channels 1 and 2.
Pushing this button in will attenuate the input signal by 20dB,
allowing you to connect a microphone or instrument to the
combo input jack.
6. +48V Phantom Power
Pushing one of these buttons will activate the +48V phantom
power for the corresponding channel, allowing you to use
condenser or ribbon microphones (or other devices that require
+48V) to work properly. Activation of phantom power will be
accompanied by an illuminated LED. If you are not sure if your
mic uses phantom power, please refer to the microphone user's
manual.

7. Headphone Output Jack and Gain Control
All the audio signals that are mixed inside the Firefly 808
Universal can be monitored with headphones through this jack.
You can also use the corresponding control to adjust the signal
level.
8. Main Level Control
This control adjusts the final level of the audio sent through the
main left and right outputs, the signal of which is taken either
from the FireWire return signal or the various analog and digital
inputs (depending on your software settings).

9. LED Level Meter
This stereo 6-segment LED meter displays the signal level of
sum of all 8 analog input channels. User's are advised to keep
this meter sitting around the -6dB mark to make the best use of
audio possible without causing any unnecessary clipping.
10. Channel LED Level Meters
The input/output signal levels from analog inputs/outputs 1
to 8 are shown in these 4-segment LED meters. Whether
these meters display the input or output level is dependant on
the input/output select button. Users are advised to try and
keep their signal level around the -20, -10 marks, as to avoid
distortion and clipping.
11. Input/Output Select Switch and Indicator
This button determines whether the LED level meter will display
the input or output signal of the Firefly 808's input/output
channels. This button is an easy way to compare input and
output levels. Depending which setting is currently active, an
LED will light up next to the corresponding setting ("analog
input" or "analog output").
