2.4 USING THE PREAMP OUTPUT AND LINE INPUT AS AN INSERT
The FireStudio Project features ¼” TRS balanced Send and Return jacks on Channels 1 and 2. These jacks are
labeled as Preamp Output (Send) and Line Input (Return). These connectors allow the use of external
processors such as compressors, limiters, EQ’s, de-essers, etc. Simply connect the Preamp Output jack to the
line input of your external processor. Then connect the line output of the external processor to the Line Input 1
or 2 of the FireStudio Project. The input signal from channel 1 and/or 2 is now routed out of the FireStudio
Project into the external processor and back into the FireStudio Project. The final, processed signal can now be
recorded using channel 1 or 2.
NOTES:
The line inputs on channels 1 and 2 are normalled to the channel 1 & 2 preamp outputs, so take precedence over
the corresponding combination 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.)
The 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.
