Configuring The Master Mix Bus Effects, Stereo Mix, and Headphone Outputs:
In addition to configuring any of the individual channels to send their outputs directly to the PreSonus
AudioBox 1818, your RECEPTOR will mix all of the synth and audio channels together and send the results
out any and all of the Line outputs that have been assigned to the Master Mix Bus. NOTE: the Master Mix
bus is assigned to Line Out 1+2 and S/PDIF output by default.
As you already know, you can add effects to the master mix bus signal using the two effects slots, but
you also have the option of taking these effects channels and sending them out their own separate sets
of outputs. This also provides you with the opportunity to use the Effects channels in SEND mode as
separately controllable stereo mix outputs, giving you not one, not two, but potentially THREE separate
stereo mixes all at the same time.
The PreSonus 1818 interface also has its own dedicated headphone output which requires a separate
signal assignment, also covered in this section.
Master Mix Bus Output Assignment
The Main Mix Outputs are by default assigned to line outputs 1+2. In addition,the
default condition is to send this signal to the S/PDIF outputsas well. You an un-
assign the S/PDIF outputs, but the outputs are hardwired to Line Outputs 1+2 to
guarantee that there will always be an output signal on the main outputs.
In addition to letting you assign the Master Mix Bus to any of the other outputs,
this is also how you will assign the main outputs to the Headphone output port.
The PreSonus AudioBox 1818 uses outputs 7+8 as the headphone outputs, so in
order to hear anything out of the headphone jack on the front of the unit you must
assign the desired output to outputs 7+8. This is so important we're going to say
it again:
NOTE: the AudioBox interface feeds the HEADPHONE jack on the front
panel from Outputs 7 and 8. You must assign Outputs 7+8 to any channel
or bus you want to monitor on headphones.
Mix Effect Output Bus Assignments
The output assignment feature of the two Mix Effect channels makes it possible to separate your "effected"
signals from your "dry" signals and send them out different outputs. This is only possible with an effect
that is in SEND mode, since an INSERT effect is, by definition, inserted into the signal chain, and to
remove it from the signal chain defeats the purpose of inserting it in the first place.
To add effects to a synth or audio channel and then send it out its own separate "wet" channel, simply click
the OUTPUT button adjacent to the effect of interest, de-assign the effect from the Master Bus, and then
assign it to its own set of outputs. Note that in SEND mode, the relative amount of each signal sent to the
effect is controlled by the SEND control on each of the synth or audio input channels.
This clever configuration also makes it possible to create up to three completely independent stereo mixes
(Master Mix Main outputs, Mix SEND effect 1 outputs, Mix SEND effect 2 outputs). To do this, simply use
the SEND control on each channel to adjust the relative mix, and then use the assigned physical output
on the Master Bus Send effect as its own independent stereo output. This is very handy for setting up a
monitor mix or separate mix that is going to a different from what is being sent out the master mix bus
outputs.
TIP: You can use the Master Mix Effects as outputs even with no effect selected. Simply place the effect
slot into SEND mode and assign an Output, and it will be available as its own separate bus.
NOTE: All audio input and output assignments are saved with your preset, so don't forget to
save your preset to retain the I/O settings.
