13 - Rear panel & connections—Other connections
13–4
This stereo signal may be routed to any combination
of the following: input channels 5-6, input channels
13-14 and
ST-IN 1
, using the
I/O SETUP
screen accessed through the
DIGITAL I/O
key (see
3.1, “I/O setup”).
Regardless of the channel assignment, the signal
received here may always be selected for monitoring
using the
D-IN 1
key of the monitor select keys
[22]
.
Using the
DIGITAL I/O
screens, this may
also be used as a clock source.
13.5Other connections
[75] POWER switch
Turns the TM-D4000 on and off.
WARNINGS
Always make sure that the TM-D4000 is
turned off when connecting or disconnecting
equipment.
Always make sure that the voltage of your
power supply corresponds to the voltage
requirements of the TM-D4000, as specified
on the rear panel by this switch.
[76] WORD SYNC OUT connector
This BNC connector provides a word clock signal
generated from the TM-D4000, for use if the TM-
D4000 is to be used as the word clock master in the
system.
This connector is unbalanced, and outputs the clock
at TTL levels. It is auto-terminating.
[77] WORD SYNC IN connector and
switch
This BNC connector accepts a word clock from an
external source. On the
DIGITAL I/O
CLOCK
screen, as described in 3.2, “CLOCK
setup”, this is referred to as
WORD
.
Set the
75ohms
terminator switch to
ON
in almost
every case. However, if a “daisy-chain” type of word
clock connection, using BNC T connectors is
employed (this is not a recommended method of
working, by the way), this switch should be set to the
OFF
position.
WARNING
There should be one, and only one, word
clock master unit in a system. If more than
one word clock master is present in a system,
there is a risk of damage being caused to
monitor speakers, etc.
The connector is unbalanced, and accepts the clock
signals at TTL levels.
[78] CASCADE IN and CASCADE OUT
These 25-pin ’D’-sub connectors are used to provide
cascade connections between the TM-D4000 and
another TM-D4000.
When making cascade connections,
CASCADE IN
connectors must be connected to
CASCADE OUT
connectors.
CASCADE IN
s should never be con-
nected to other
CASCADE IN
s, and
CASCADE
OUT
s should never be connected to
CASCADE
OUT
s.
For full details of cascade operations, refer to the sec-
tion on “Cascade”.
[79] TO METER
This 37-pin ’D’-sub connector is used to make the
connection between the optional MU-4000 meter
bridge unit and the TM-D4000.
[80] RS-422
This 9-pin ’D’-sub connector is used for connecting
to the control inputs of remote devices which use the
Sony P2 or other “9-pin” control protocols supported
by the TM-D4000.
[81] TO HOST
This 9-pin ’D’-sub connector is used for making a
serial connection (RS-422) to the computer running
the automation software to control the TM-D4000.
[82] MIDI IN, OUT and THRU
These three 5-pin DIN connectors correspond to the
MIDI standard (
MIDI IN
receives MIDI data,
MIDI
OUT
outputs MIDI data originated by the TM-
D4000, and
MIDI THRU
echoes data received at
MIDI
IN
).
The MIDI is used for MIDI Timecode, Program
Change and Control Change messages, as well as for
MIDI System Exclusive bulk data dumps, etc. The
details of these are all given in the section on MIDI.
[83] TC IN
This RCA connector provides a way for the TM-
D4000 to accept linear timecode as an unbalanced
signal.
The input impedance of this connector is 20 k
Ω
, and
the input level is –30 dBV.
