5. Select [D.out adat] by using the JOG dial, and press the EXECUTE/YES key.

Now the Digital Out is set to "adat".

Setting the reference clock

When setting "Digital In" (see the previous page) to an "Async" mode ("adat:Async" or "SPDIF:Async"), you must select whether the recorder is referenced to the internal clock or word clock from an external digital device. When setting "Digital In" to a "Sync" mode ("adat:Sync" or "SPDIF:Sync"), the recorder is refer- enced to the word clock received through the exter- nal digital audio signal.

6. Select the [Clock Sel?] menu via using the JOG dial, and press the EXECUTE/YES key.

The current reference clock is displayed together with "Clock Sel?". The default is [Clock Sel? Int].

Press the EXECUTE/YES key, and the current selection will start flashing.

7. Select the desired reference clock by using the JOG dial, and press the EXECUTE/YES key.

The reference clock is now set to your desired clock. When connecting the recorder to a digital mixing console that can accept the word clock from the WORD OUT of the recorder, set the recorder's reference clock to [Int].

See the table below in other cases.

<About reference clock setting>

You must set the reference clock when setting "Digital In" (see the previous page) to an "Async" mode ("adat:Async" or "SPDIF:Async"). You can select from [Auto], [Word] and [Video] in addition to the default [Int]. Note that [Video] is available only when the optional TC/ SYNC card (model 8345) is installed.

See the table below about the relation between the Digi- tal In setting and reference clock.

8. Press the EXIT/NO key or STOP button to exit the SETUP mode.

The display shows the beginning of the disk with ABS time base.

After complete [Digital In], [Digital Out] and [Refer- ence Clock] settings, execute the basic recording in a similar manner to "Basic analog recording" described earlier.
