Basic operation

1
3
1
Press the POWER button to turn the unit on.
The power indicator lights blue.
o When the power is turned on, the unit starts warming the
crystal oscillator (OCXO) up to its operating temperature. It
takes two minutes for the oscillator frequency to stabilize.
V
When you do not plan to use the unit for an extended
amount of time, turn the preheat (PrHEAT) setting
OFF and press the POWER button to turn the unit off.

Make clock output settings.
When using the CLOCK OUT connectors
1) Set the clock reference frequency to 44.1 or 48 kHz.
Press the MENU button to open the FREQ menu and use the A
and B buttons to set the frequency mode (pages 14–15).
44 (44.1 kHz)
Use for playback of CDs, Super Audio CDs and other
44.1kHz sources.
48 (48 kHz)
Use for playback of DVDs, DATs and other 48kHz sources.
(Some DVDs and DATs are recorded at 44.1  kHz. In this
case, use the 44.1kHz setting.)
o When using only universal clock (100  kHz or 10  MHz),
either setting is fine.
o Only use 44EXP or 48EXP for frequencies that are not cov-
ered by the 44 and 48 modes (page 15).

2) Use the A and B buttons to set the frequencies
sent to connected devices (page 11).
When setting 10MHz OUT connectors
Press the 10MHz button to turn output on and off.
Use the menu to set which 10MHz OUT connectors (1–4) to use
(page 16).
o If you do nothing for five or more seconds, setting mode will
end and ordinary display will resume. (If DISP is set to SHORT,
this will happen after three seconds.)

On the connected devices, turn clock sync ON
(or set to slave mode).
Read the owner's manual for each device for instructions on how
to set their clock sync status properly.
If you connect this unit to devices from other manufacturers, be
sure to read the manuals of those devices to confirm the clock
frequencies that they can receive.
Some devices require the clock frequency to be set to the same
value as the audio signal sampling frequency.
Some dual AES connections might require that the clock fre-
quency be set to half of the audio signal frequency.
o Due to the nature of the crystal oscillator (OCXO), continuous
operation stabilizes the precision of operation, so we recommend
turning the preheat (PrHEAT) setting ON (page 16).
o Settings are retained even when the power is turned off.
o Once settings have been made, those settings can be used when
the power is turned on again.
Set the frequency mode according to the type of disc to be
played or device being used (page 15).
