VARI PITCH key LED turns off.)
Stop the recorder. (The STOP
button LED turn off.)
Turn off the TRACK SHIFT key LED.
Turn off AUTO RTN mode and AUTO
PLAY mode. (AUTO RTN and AUTO
PLAY indicators turn off.)

About Sampling Frequency
You need to reset all the controls on this recorder to their initial settings according to the controls and switches on
the mixer before you proceed to the next step. This procedure is called “Initialize” in this Guide and in the
Reference Manual. The buttons and switches on this recorder should be reset as shown below. Remember to
“initialize this recorder” before you start a new session.
The sampling frequency is important when recording a digital source, as described later in "Basic digital
recording", but is not as important when recording analog source.
As described earlier in "Formatting a hard disk drive", the sampling frequency and quantization of the cur-
rent drive (<44.1 kHz 16bit or 24bit>, <48 kHz 16bit or 24bit> or <96 kHz 24bit>) are fixed when formatting.
Therefore, the sampling frequency of a digital device connected to the recorder must match the recorder's
sampling frequency.
For example, if you record a CD source digitally, the recorder's sampling frequency must be 44.1 kHz because
the sampling frequency of a CD source is 44.1 kHz. If you use the 48 kHz digital signal of adat, the recorder's
sampling frequency must be 48 kHz.
The sampling frequency selected when formatting the disk is indicated in the display.
<Hints>
* When connecting the recorder to a digital mixing console as shown in the example above, unlike connecting to an
analog console, both digital devices must be synchronized with each other.
To achieve this, use "word clock," the signal for synchronization.
Word clock is used to synchronize all digital words in a system. Normally one digital devices in the system acts as
a master of word clock, and the other devices act as slaves. All the slave devices receive the word clock fed from the
master device and synchronize to it. In the example above, the recorder acts as a word clock master and the digital
mixing console acts as a slave and synchronizes with the recorder. The word clock is fed from the WORD OUT
terminal of the recorder to the WORD IN terminal of the digital mixing console.
* Note that the master word clock setting of the digital mixing console must match the recorder's sampling frequency.
See the instruction manual of the digital mixing console for details.
To execute the digital multitrack recording using a digital mixing console, see "Basic digital recording" on page 17
for details about the digital multitrack recording using a digital mixing console.
