The FD-4 features a four-channel mixer function that en-
ables you to mix four sound sources into a stereo mix.
Since the mixer functions and signal flow are not visible,
the following diagram will help you understand them.
The diagram shows the flow of signals from the inputs
through the mixer section to the recorder.
The thick line in the diagram is called the “stereo bus”,
which collects the channel signals that are panned and pro-
cessed by the EQ.  The signals are adjusted for the final
level by the master faders L/R, then routed to the STEREO
OUT L/R jacks.  The same signals are routed to the recorder
(external SCSI disk) and recorded in the specified tracks.
In this case, the PAN knobs function like a turn signal to
stereo buses L and R.  As shown in the diagram, rotating the
PAN knob toward L will cause signals to be sent to stereo
bus L.  Rotating the PAN knob toward R will cause signals to
be sent to the stereo bus R.  Stereo bus L signals are then
routed to Real tracks 1 and 3 and Additional track L.
Stereo bus R signals are routed to Real tracks 2 and 4 and
Additional track R.  You can select a recording track using
the RECORD TRACK select keys. (You can record to Addi-
tional tracks in real-time only on the disk in Mastering mode
1 or Normal mode.)
For example, to record all sound sources input to channels
1–4, turn all channel PAN knobs completely to L, and press
the RECORD RACK select key 1/L to set the track READY.
