Rear panel tour
AC connector
This is where a standard IEC
detachable power cord plugs
in.
POWER switch (hard)
Normally, you'll leave this
switch on, controlling power
from the front panel switch.
Always turn off the unit using the
front panel POWER
switch first. The "soft"
power-off procedure
parks the drive heads,
so they may be removed
safely.
Ethernet
Connect this jack to a computer
to transfer audio to any
workstation. Each Song will
appear as a folder containing
each track as a separate .WAV
or .AIFF file. Since the HD24
uses FTP, you can even connect
this jack to a cable modem to
transfer files over the Internet.
See Chapter 9: Ethernet.
Analog I/O
These
INPUT
and
OUTPUT
jacks
may be connected to balanced
or unbalanced mixers, since
they're 3-conductor balanced
1/4” phone jacks (also called
TRS for “tip-ring-sleeve”).
See
Chapter 2: Connections
.
Word clock input
Connect the word clock output
of a digital mixer or master
clock source to this jack, to
ensure that everything in the
studio samples at exactly the
same time, avoiding ticks and
clicks.
LRC and PUNCH
Connect the LRC remote
control (supplied) to the LRC
jack, and any momentary
footswitch (optional) to the
PUNCH jack for hands-free
recording.
MIDI
MIDI IN allows the HD24 to
follow MMC commands from a
sequencer, and MIDI OUT can
transmit MMC and MTC (MIDI
Time Code).
See
Chapter 8:
Synchronization and MIDI .
ADAT Optical (Digital
I/O)
Each of these connectors carries
8 channels of digital audio
information (or, 4 channels at
the 88.2/96 kHz sampling rate).
See
Chapter 2: Connections
.
ADAT Sync
Connect a remote control (such
as the BRC™) to the
SYNC IN
jack. Or, connect a 9-pin cable
from the
SYNC OUT
jack of
another ADAT unit here to
expand a system to as many as
120 simultaneous tracks.

Chapter 8: Synchronization and MIDI
and Chapter 2: Connections
