Model D2424LV Quick Operation Guide 
<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 PUT] terminal of the recorder to the [WORD INPUT] 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 “16” for details about the digital multitrack recording using a digital mixing console.
Initial settings
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.
Locate the top of the selected Program (ABS 0).
Turn off AUTO RTN mode and AUTO PLAY mode. (AUTO RTN and AUTO PLAY indicators turn off.)
Turn off AUTO PUNCH mode. (The REHEARSAL and TAKE LEDs go off.)
The [STORE] key and [RECALL] key LEDs turn off.

Stop the recorder. (The STOP button LED turn off.)
Turn off the Vari Pitch function. (The [VARI PITCH] key LED turns off.)
“SAFE.” The track indicators (square frames) turn off.
About Sampling Frequency
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 current drive (<44.1 kHz 16bit or 24bit>, <48 kHz 16bit or 24bit>, <88.2 kHz 24 bit> 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.
In this recorder, the program to be complied in the current drive after formatting can be changed to any sampling frequency. When several programs recorded using different sampling frequencies are in the cur- rent drive, sampling frequencies must be confirmed at each change of the program.
