AW2400 Owner’s Manual

EDEVICE NO. box

Speciﬁes the MMC device number (1–127) that the

AW2400 will receive.

FMTC ﬁeld

Speciﬁes how the AW2400 operates when synchronized

with an external MIDI device using MTC (MIDI Time

Code).

GMTC MASTER button

When this button is on the AW2400 functions as MTC

master. Turn this button on when you want external equip-

ment to synchronize to the AW2400.

HMTC SLAVE button

When this button is turned on the AW2400 functions as

MTC slave, and will follow MTC received via the MIDI

IN connector (or USB connector or digital I/O card input

port). Turn this button on when you want to synchronize

two AW2400 units, or synchronize the AW2400 to an

external device that can only function in MTC master

mode.

ISYNC AVERAGE box

Select one of the following to specify how closely the

AW2400 will follow the incoming MTC data when func-

tioning as an MTC slave.

•0.............The AW2400 will synchronize to the incoming

MTC data with the highest precision. If the

incoming MTC has signiﬁcant instability, syn-

chronization may be interrupted or become

unreliable with this setting.

•1.............This setting provides more tolerance to MTC

instability than the OFF setting.

•2.............This setting allows the maximum tolerance.

Use this setting if the MTC master is an exter-

nal MIDI device that has signiﬁcant instability.

JOFFSET

When using the AW2400 as an MTC slave, this parameter

shifts the absolute time of the AW2400 forward or back-

ward relative to the incoming MTC. The range is

-24:00:00:00.00 to +24:00:00:00.00.

KSYNC OUT ﬁeld

Selects the type of MIDI message to be used for synchro-

nization.

• OFF button ........Engage this button (it will appear

inverted) to disable transmission of

MIDI synchronization messages.

• MTC button .......When this button is ON MTC will be

transmitted while the recorder is run-

ning.

• MIDI CLOCK Button

...............When this button is ON the MIDI clock

will be transmitted while the recorder

is running. Also, appropriate START,

STOP, CONTINUE and SONG POSI-

TION messages will be transmitted

when the transport is operated.

• The MMC device number is an identifying number used to distin-

guish devices that transmit and receive MMC commands. When

using MMC, the AW2400 and the external MIDI device must be set

to the same MMC device number.

• When transmitting MMC data from the AW2400, the MMC device

number is always set to “128” (allowing control of all MMC-com-

patible devices).

NOTE

• If the accuracy of the incoming MTC becomes unstable when the

AW2400 is functioning as an MTC slave and is synchronized to an

external MIDI device, the AW2400 will make slight adjustments in

playback pitch in an attempt to maintain synchronization. The

SYNC AVERAGE parameter speciﬁes the range of MTC variance

that will be tolerated.

• The OFFSET setting has no effect on MTC output via the MIDI

OUT/THRU connector (or USB connector or digital I/O card output

port).

HINT

•MIDI clock operation is based on the tempo speciﬁed in the Tempo

Map (refer to page 175 for Tempo Map setup details).
