more information.
When synchronizing to ADAT timecode, the 1212 I/O's word clock source
cannot be set to Internal.
SMPTE and MTC offsets have no effect on ADAT timecode
Some ADAT devices, such as the Alesis BRC and Fostex RD-8, allow you to
enter SMPTE and/or MIDI Time Code (MTC) offsets from the normal
ADAT timecode. It is important to remember that these offsets do not affect
the basic ADAT timecode itself, as it is sent along the ADAT sync cables;
the offsets only affect synchronization through the device's SMPTE or
MIDI inputs and outputs.
The 1212 I/O listens only to the simple, unadulterated timecode carried on
the ADAT sync cable. This means that entering a SMPTE offset on the BRC,
for instance, has no effect on the sync received by the 1212 I/O.
Using Premiere Plug-Ins with 1212 I/O-compatible software (MacOS)
Premiere Plug-Ins automatically use the Apple Sound Manager for
preview audio output. When the 1212 I/O is selected as the Sound
Manager output device, the previews will play back through the 1212 I/O.
Since Premiere Plug-Ins use the Sound Manager, they are totally unaffected
by the output assignments in software which directly supports the
1212 I/O (such as Deck II); instead, they use the output channels assigned
to the Sound Manager in the 1212 I/O Utility.
For more information on using the 1212 I/O with the Sound Manager,
please see the chapter "Sound Manager (MacOS)," beginning on page 39.
Using the Alesis BRC: 1212 I/O output to ADAT input
The BRC's track routing features (under the BRC's Digital I/O button)
control the digital I/O routing for the ADAT system. When copying tracks
between ADATs, the BRC is used to select one or more source tracks on a
single ADAT machine; this machine becomes the digital audio
"transmitter," and the selected tracks are sent out on the optical bus. All the
other ADATs in the system become audio "receivers," listening to the
output of the transmitter and passing it on to their own outputs.
When using the 1212 I/O as the digital I/O source, all of the ADATs need
to be receivers. If one of the ADATs is acting as a transmitter, then it will
block the output of the 1212 I/O to all subsequent ADATs in the optical
loop.
The diagram below shows the 1212 I/O connected to a three-ADAT
system, with the optical inputs and outputs of all the devices chained
together. Using the digital I/O routing feature of the BRC (not shown),
