Before Starting

Signal flow (The PAN knob function and Stereo Bus)

The FD-8 is equipped with an eight-channel mixer function, which enables you to mix and record eight sound
sources into stereo signal. The following diagram is designed to help you visualize the signal flow of the FD-8.
It illustrates how input signals are routed through the mixer and sent to the recorder section.
The thick pipes in the diagram are called the "Stereo Bus," which collects input channel signals passing through
the equalizers and distributes them to L or R via the PAN knobs. The signal is adjusted for final output by the
master faders L/R, then output from the STEREO OUT L/R jacks. At the same time, the signal is sent to the
recorder (external SCSI disk) and recorded onto the tracks selected by the RECORD RACK select keys.
The PAN knobs function as a "turning signal" to Stereo Bus L or R. That is, turning the PAN knob toward L will
send signals to Stereo Bus L, and turning the PAN knob toward R will send signals to Stereo Bus R. If you set the
PAN knob in the center, signals are sent equally to Stereo Bus L and R. At the same time, Stereo Bus L signals are
finally sent to Real tracks 1, 3, 5, and 7, and Stereo Bus R signals are sent to Real tracks 2, 4, 6, and 8.
Recording tracks are selected via the RECORD RACK select keys.
For example, if you input three sound sources (guitar, vocal, and keyboard), set the channel PAN knobs as shown
below, and press the RECORD RACK select keys 1/L and 2/R to record the sources to tracks 1 and 2, the sound
sources are recorded to tracks 1 and 2 as shown below.
If you wish to record all eight sources input to Channels 1-8, turn all channel PAN knobs toward L, and press the
RECORD TRACK select key 1/L to select track 1 as a recording track.

Note:
The FD-8 is capable of eight-track simultaneous recording. (Except that using an MO disk will limit this
number to two tracks.)
For example, if you connect all instruments to the input channels as shown above and select all tracks for
recording, guitar and vocal sounds will be recorded on tracks 1, 3, 5, and 7, and keyboard and vocal sounds to
tracks 2, 4, 6, and 8.
