CONTROLS AND CONNECTIONS
33 | PreSonus 2009
 Main Output. The audio source for the Main outputs is identical to that of General Purpose outputs 1
and 2 (DAW Playback 1 and 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 and 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.
 Return 1 and 2 (Line Inputs). These are the line-level inputs for channels 1 and 2. Their gain structure
is identical to the ¼” inputs for channels 3-8 and are typically used for signals not requiring
preamplification (CD/MP3 players, effects processors, etc.). These inputs are normalled to the channel
1 and 2 preamp outputs, so they take precedence over the corresponding Mic/Instrument input on the
front of the FireStudio Project. (This means that if a cable is plugged into the channel 1 return input on
the rear of the FireStudio Project, the channel 1 Mic/Instrument input will be inactive, and it will
become active again when the cable is removed from return input 1.)
 Send 1 and 2 (Preamp 1 and 2 Outputs). These ¼” jacks are balanced outputs of the preamps on
channels 1 and 2. They are half-normalled to the preamp inputs 1 and 2, so plugging a cable into either
of the preamp outputs does not interrupt the signal flow from the preamps to the AD converter.
Note: The Send outputs are typically used for patching in external signal processors (such as
compressors, limiters, EQs, and de-essers) to process the audio signals on channels 1 or 2. These
outputs are not connected to the digital-to-analog converters and so are only capable of routing the
input signals from channels 1 and 2. If you need to route recorded audio or input from channels 3
through 8, you will need to use the FireStudio Project Device window to route the input to one or more
of the General Purpose Outputs.
