Adjust the DAC locking range
This function allows adjustment for those times
when the ultimate in high fi delity sound quality is
demanded.
Even with the same jitter clock input, by narrowing
the locking range, collateral sounds and overtones
can be reduced, thus raising the quality of the
sound.
However, if the locking range is narrowed
excessively, input signals with a high level of jitter
may cause the lock to slip, producing interruptions
or dropouts in the sound. In such cases, adjust
the locking range to a slightly wider value while
listening to the sound, until the sound returns to
normal.
Signal dropout when the locking range is narrowed
(other than at normal times) falls outside warranted
operating conditions. In such cases, widen the
locking range setting until the dropout stops.
This unit records the adjusted locking range set for
each independent input source.
1 Select lock range setting mode.
Press the remote control’s LOCK RANGE button and
enter the setting mode.

2 Change the setting.
Press the remote control’s FINE +/− buttons to change
the locking range. Each time one of the buttons is
pressed, the set value changes (4 steps), as follows.
FINE (−) button (pressed once):
narrows locking range
L O C K R A N G E
| - - - >
FINE (+) button (pressed once):
widens the locking range
L O C K R A N G E

• If the setting is changed to any value other than
the default “normal”, the front-panel LOCK RANGE
ADJUST indicator will light.
• If any button on the remote control other than FINE
+/− is pressed, the display window will change to
show the current input source.
 For advanced users
If the
LOCK RANGE button is held depressed for
fi ve seconds or more, the ability to narrow the
lock range will be extended by three additional
steps. However, as noted in the “Caution” note
below, users should be aware that using these
extended steps will produce a very delicate
mode easily subject to dropouts.
Lock range setting can
be extended by 3 steps.

Caution
• Even more delicate sound quality adjustments
are possible, but the frequency of dropouts greatly
increases, with the result that these steps should
not be taken except by advanced users. In particular,
when two tracks with differing sampling frequencies
and bit rates are played consecutively, the playback
may demonstrate a high propensity for dropouts.
• Even if Up Sampling has been set and the sampling
frequency raised, sound will still be prone to
dropouts.
• If signal dropout occurs, try readjusting the lock
range to a wider value so that the sound appears
normal. Narrowing the width of the lock range
setting (other than in normal conditions) is
considered outside the range of warranted operation
as regards signal dropout. In such cases, widen the
lock range setting until dropouts do not occur.
• To return the lock range to the standard 4 steps,
return the setting to factory defaults (see page 11: To
return settings to factory defaults).
Operation
Setting auto power down
This function automatically turns off the power if
no input signal (including silence) or other user
operation is detected for a period of 15 minutes.
• Factory default setting: ON
1 Set auto power down.
With the power set to OFF, hold the front-panel  /|
STANDBY/ON button depressed for 5 seconds or
more until power turns ON.
Use the same procedure to turn the auto power down
setting OFF.

Note
• If even an inaudible level of signal is detected, the unit will
consider it a valid signal, thus preventing the auto power
down function from operating.
Adjusting the level of illumination (DIMMER)
in the display window and indicators
Adjust illumination in the display window.
When set to OFF, the display window and indicators
are turned off. By disconnecting power to the
display window, minute amounts of electronic noise
can be reduced.
• Factory default setting: 4 (brightest)
1 Adjust the dimmer.
Repeatedly pressing the remote control’s DIMMER
button cycles the display illumination through 4 levels
and OFF (4
