1)
Time Code Multi-Pin
Time code input and output on 5-pin
LEMO
®
connector.
2)
AES3id Inputs 1/2 and 3/4
Unbalanced digital input accepts two
channel AES3 (or S/PDIF) on BNC con-
nectors. Supports sample rates up to 200
kHz.
3)
FireWire (IEEE-1394) Port
Connection to a computer (Mac OS,
Windows 2k/XP, Vista, Linux) to access
the internal hard drive and Compact-
Flash volumes as mass storage devices.
Also used to attach external FAT32-for-
matted FireWire drives to the 744T for
direct recording and copying.
4)
C. Link In/Out
RS-232 protocol interface on 6-pin
modular (“RJ-12”) connector for link-
ing multiple 7-Series recorders together.
Word clock, machine transport, and time
code are carried on the C. Link connec-
tor.
5)
External DC In
Accepts sources of 10–18 volts DC for
unit powering and removable Li-ion
battery charging. The Hirose 4-pin con-
nector is wired pin-1 negative (
-
), pin-4
positive (+). Pin-2 (
-
) and pin-3 (+) are
used to charge the removable Li-ion
battery. DC ground at both pins-1 and
2 is at the same potential as chassis and
signal ground.
6)
Word Clock Input and Out
Provides clock input and output for the
744T. Word input accepts sampling rates
between 32 kHz and 192 kHz. Word
clock output is the rate that box is run-
ning. There is no sample rate conversion
onboard the 744T.
7)
AES3id Output Bus 2
Unbalanced digital output, two-channel,
for Output Bus 2. Signal source is menu-
selected.
8)
AES3id Master Output Bus
Unbalanced digital output, two-channel,
for the Master Output Bus. Signal source
is menu-selected and is identical to the
Analog Master Output Bus signal.
9)
Multi-Function Rotary Switch
When in the setup menu, the rotary
switch moves between menu selections;
push to enter selection or enter data.
In record and playback modes, selects
headphone monitor source; push action
is user selectable.
