6 - Hookup-Synchronization and control connections Word sync clock connections NOTE In every digital audio setup, there must be one, and only one, word sync source. If there is more than one source in a system, there is a risk of causing damage to the monitoring system (and your hearing). The DM-24 can act as either a word sync clock master or as a slave. In the case of the DM-24 acting as a master for the system, make sure that the switch by the BNC word sync connectors is in the center position (75-ohm IN termination is OFF, and the DM-24 generates the word sync signal from the OUT terminal). In the case of the DM-24 being a word sync clock slave, it is possible for the DM-24 to either retransmit MIDI connections Make these connections following the usual MIDI standards See "MIDI" on page 95 for details of how the DM-24 uses MIDI. SMPTE/EBU timecode connections SMPTE/EBU analog timecode is received at the TIME CODE IN connector on the rear panel The timecode is needed when using the automated mix functions. Meter unit The optional MU-24/DM meter unit may be connected to the TO METER connector. P2 connections Devices which implement the P2 protocol can be controlled by the DM-24. the word sync to other units, or to act as the last unit in the word sync chain. When retransmitting the sync, set the switch to the left position (75-ohm IN termination is OFF and the OFF/THRU setting is set to THRU). If the DM-24 is the last unit in the word sync chain, the switch should be in the right position (75-ohm IN termination is ON). All input and output is at TTL level. Select the word sync source using the CLOCK screen in the DIGITAL section ("CLOCK settings" on page 24). NOTE It is not recommended that any ADAT unit is set up to be a word clock slave. Also see "SYNC/TC" on page 23 for further details of MTC operation. Note that the DM-24 does not output analog timecode, but can output MTC for use by other units. See "SYNC/TC" on page 23 for details of setting up the DM-24 to use the timecode. Consult the documentation with the meter unit for full details of installation and using the meters with the DM-24. See "Machine Control/Location" on page 80 for full details of control of other devices using the DM-24. 48 TASCAM DM-24 Reference Manual

TASCAM DM-24 Reference Manual

Word sync clock connections

NOTE

In every digital audio setup, there must be one, and

only one, word sync source. If there is more than one

source in a system, there is a risk of causing damage to

the monitoring system (and your hearing).

The DM-24 can act as either a word sync clock mas-

ter or as a slave.

In the case of the DM-24 acting as a master for the

system, make sure that the switch by the BNC word

sync connectors is in the center position (75-ohm

termination is

OFF

, and the DM-24 generates the

word sync signal from the

OUT

terminal).

In the case of the DM-24 being a word sync clock

slave, it is possible for the DM-24 to either retransmit

the word sync to other units, or to act as the last unit

in the word sync chain.

When retransmitting the sync, set the switch to the

left position (75-ohm

termination is

OFF

and the

OFF/THRU

setting is set to

THRU

If the DM-24 is the last unit in the word sync chain,

the switch should be in the right position (75-ohm

termination is

All input and output is at TTL level.

Select the word sync source using the

CLOCK

screen

in the

DIGITAL

section (“CLOCK settings” on

page 24).

NOTE

It is not recommended that any ADAT unit is set up to

be a word clock slave.

MIDI connections

Make these connections following the usual MIDI

standards

See “MIDI” on page 95 for details of how the DM-24

uses MIDI.

Also see “SYNC/TC” on page 23 for further details

of MTC operation.

SMPTE/EBU timecode connections

SMPTE/EBU analog timecode is received at the

TIME CODE IN

connector on the rear panel

The timecode is needed when using the automated

mix functions.

Note that the DM-24 does not output analog time-

code, but can output MTC for use by other units.

See “SYNC/TC” on page 23 for details of setting up

the DM-24 to use the timecode.

Meter unit

The optional MU-24/DM meter unit may be con-

nected to the

TO METER

connector.

Consult the documentation with the meter unit for

full details of installation and using the meters with

the DM-24.

P2 connections

Devices which implement the P2 protocol can be

controlled by the DM-24.

See “Machine Control/Location” on page 80 for full

details of control of other devices using the DM-24.
