Adjust the DAC locking range

This function allows adjustment for those times when the ultimate in high fidelity 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.

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 five 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.

L O C K R A N G E

¦ - - - - - - - >

Lock range setting can be extended by 3 steps.

Normal settings

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).

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
