How to use the RECORDER IN jack

The following explains the various functions of the RE-
CORDER IN jack.
There are two ways to use the RECORDER IN jack.
1. Synchronizing an external MIDI sound source with the performances
recorded on tracks 1 ~ 4 and digitally mixing down a maximum of
eight channels of sound sources.
2. Directly recording external sound sources without routing them
through a mixer.
Eight channels of digital mixdown
In this method, the RECORDER IN (L, R) jacks of the FD-4 are
directly connected to the MON OUT (L, R) jacks and the moni-
tor SELECTOR switched to [L/R+MON]. Then, the monitor bus
L, R signal and the stereo bus L, R signals are both simulta-
neously output from MON OUT L, R and input to RECORDER IN
L, R. As shown in the drawing below, an external MIDI sound
source is input to INPUT jacks 1~4, and then each channel
INPUT fader is raised, and performances recorded on tracks
1~4 are applied to each channel MON mix section, and played
back using MIDI sync of both performances. With this method,
a maximum of eight channels (Tracks 1~4 and MIDI sound) of
sound sources are mixed and sent to the RECORDER IN L, R
from MON OUT L, R, and digitally mixed down in an outboard
digital device (DAT).

Å@Special Application (How to use the RECORDER IN jack)
Direct recording of an external sound source
Here, an external sound source is directly input to the RECORDER
IN jack of the FD-4 and recorded in the recorder section without
passing through a mixer.
In this case, if an external input is connected to L and R of the
RECORDER IN jack, it will not be possible to record through the
mixer section.
In the illustration below, the signal input to L of RECORDER IN is
sent to tracks 1, 3 and L, and the signal input to R of RECORDER IN
is sent to tracks 2, 4 and R. Any two tracks are selected for record-
ing. If the connection is made from the mixer group out, using a
patch bay will faciliate connections from the front panel as shown
in drawing below. The recording level is adjusted at the external
equipment side and, by setting the monitor section SELECTOR to
[MON] at the FD-4 side, sound can be monitored using the MON
mix section of the channel corresponding to each track. Recording
onto the additional track is possible only in the normal mode and
mastering mode 1.

<More applications for using RECORDER IN>
If an external sound source is connected to both L and R of RECORDER IN,
recording cannot be done via the INPUT fader. If only one jack (L or R) is con-
nected, the track corresponding to the jack not connected can be recorded simul-
taneously via the INPUT fader. For example, if sound source E is connected to
only L of RECORDER IN, another sound source applied via the INPUT fader can
be recorded on any one of tracks, 2, 4, R corresponding to R of RECORDER IN to
which nothing is connected. In other words, because the FD-4 can simultaneously
record two tracks, a sound source from RECORDER IN can be recorded on one
track and sound source routed via the INPUT fader can be simultaneously re-
corded on the other track.
