NOTE: MIDI is not audio but is frequently used to trigger or control an audio source (such as a VST
plugin or synthesizer). When using MIDI, ensure your MIDI data is correctly sent and received
by the appropriate hardware or software instruments. You may also need to return those
devices’ audio to the FireStudio Project. Please consult the User’s Manual of your MIDI
devices for help with MIDI setup and usage.
• Main Output. The audio source for the Main Outs is identical to that of General Purpose outputs 1 & 2
(DAW Playback 1 & 2 by default). The difference is that the output level of the Main Outputs is
controlled by the FireStudio Project Main volume knob on the front of the unit.
• General Purpose Line Outputs (TRS Balanced). These are general purpose line-level outputs. Line
Outputs 1 & 2 are typically your computer’s audio playback. All eight Line Outputs can be accessed by
your computer and can be used for separate mixes, additional speakers, external effects processors, etc.
NOTE: By default, the General Purpose Outputs are DAW Playback 1-8 streams from your computer.
However, the FireControl has final control over their audio sources.
• Line Inputs. These are the line-level inputs for channels 1 & 2. Their gain structure is identical to the
¼” inputs for channels 3-8 and are typically used for signals not requiring preamplification (like
CD/MP3 players, effects processors, etc.) These inputs are normalled to the channel 1 & 2 preamp
outputs so take precedence over the corresponding Mic/Instrument input on the front of the FireStudio
Project. (I.E., if a cable is plugged into channel one line input on the rear of the FireStudio Project,
the channel one Mic/Instrument input will be inactive until the cable is removed from line input one.)
• Preamp Outputs. These ¼” jacks are balanced outputs of the preamps on channels 1 & 2. They are
half-normalled to the line inputs 1 & 2, so plugging a cable into either of the preamp outputs does not
interrupt the signal flow from the preamp outputs to the line inputs (and to the ADC).
NOTE: The Preamp Outputs are typically used for patching in external signal processors such as
compressors, limiters, EQ’s, de-essers, etc. to the audio signals on channels 1 or 2. These Preamp
Outputs are not connected to the DAC (digital to analogue converters) in any way and so are only
capable of routing the input signals from channels 1 & 2. If you need to route recorded audio or input
from channels 3-8, you will need to use your recording software and one or more of the Line Outputs.
