ADAT HD24 Reference Manual
Input Monitor Controls
There are two Input Monitor controls:
AUTO INPUT
and
ALL INPUT
.
Auto Input
This feature determines what you will hear from
the HD24’s output jacks when a track is record-
enabled (
REC
LED flashing): the track, or the input
source. The
AUTO INPUT
button toggles the Auto
Input Monitor on and off.
At the bottom of the display,
AUTO
will light in
yellow under the
MONITOR
icon.
When a track is monitoring its input signal, its
INPUT
LED (the blue indicator under the meter) will
be lit.
• When Auto Input Monitor is off , all record-
enabled tracks will monitor the input signal
and all other tracks will monitor the playback
signal.
• When the Auto Input Monitor is on (
AUTO
icon is lit), you'll hear the playback of the
track right until the moment of punch-in,
when it will switch to the input signal. You’ll
hear the input to record-enabled tracks
during record, stop, rewind or fast fwd, but
not in play.
The reason for having these two options is to
accommodate different stages of the recording
process. Leaving the Auto Input Monitor off is
the “normal” option and is what you would use
when first recording tracks. When performing
punch-ins and overdubs, you will probably want
to turn the Auto Input Monitor on so that you can
hear what was recorded on tape for a given track
right up to the point you want to punch in. As
soon as the HD24 punches into record mode, the
recorded signal is replaced by the input signal so
you can hear what’s being recorded. After you
punch-out, the monitor reverts to playback.
Typically, Auto Input should be on when the
Rehearse feature is used (see page 48).
All Input
When the
ALL INPUT
button is on (
ALL
icon under
the
MONITOR
icon is lit), the Auto Input Monitor
setting is overridden so that all tracks monitor
their input signals regardless of their record
enable status. All of the song’s tracks
INPUT
LEDs
will be lit. When All Input Monitor is off (
ALL
icon is off ), the Auto Input Monitor setting
determines track monitoring.
The following table indicates the status of tracks
that are record-enabled and tracks that are safe,
depending on the status of the
AUTO INPUT
and
ALL INPUT
buttons:
