This diagram shows an electric guitar connected directly to channel 1 (with the hi-z switch engaged),
a bass guitar connected directly to channel 2 (also with the hi-z engaged), a condenser microphone on
channel 3/4 with the phantom power engaged, a drum machine connected to channel 5/6, and a key-
board connected to channel 7/8. A headphone amplifier allows for multiple headphone use during the
recording process.
A pair of Mackie MR8 powered reference monitors are connected to the left and right control room out-
puts, for careful and accurate monitoring of the performances in the control room.
A laptop computer connects to a FireWire port, allowing each channel to be recorded and two chan-
nels from the laptop to be played back. Note: You can record a maximum of 8 channels via FireWire if
you do not record the auxes or main mix.
The DAW gets the 8 individual channel tracks. You can then mix down the project within the DAW at a
later time. These individual tracks can be pre-EQ or post-EQ depending on the channel pre/post switch-
es. Post-EQ allows you to use the mixer's high-quality Perkins EQ in your recordings. Software plug-ins
can be used for the effects processing of different tracks, and software amplifier emulators can be used
on the guitars to give the sound of mic'd amps.
Your carefully mixed 2-channel mix can be sent back to the control room via FireWire, by engaging the
FW 1-2 switch in the control room/phones matrix, and sent to the band with the headphone amp fed by
the phones out.
