Automatic Standby function
When you play a source, the power of this unit turns on
automatically by sensing audio signals input to this unit. This
unit turns into the standby mode automatically if the source
being played is stopped or the low frequency input signal is
cut off for several minutes.
This function will operate by sensing a certain level of low
frequency input signal. Its sensitivity is high in the HIGH
position and low in the LOW position of the AUTO STANDBY
switch. In the HIGH position, the power will turn on even with
a low level of input signal, but on the other hand this unit may
not turn into the standby mode when there is an input signal
even if its level is extremely low.
* There may be a case that the power turns on unexpectedly
by sensing noise from other appliances. If it occurs, set the
AUTO STANDBY switch to the OFF or LOW position.
* The level of low frequency input signal differs with each
source, and each different part on the same source. So,
this function may not operate properly depending on some
sources.
This function is available only when the power of this
unit is on (by setting the STANDBY/ON button Ÿ to ON).

PHASE switch
Normally this switch is to be set to the REV (reverse)
position. However, according to your speaker systems or
the listening condition, there may be a case when better
sound quality is obtained by setting this switch to the NOM
(normal) position. Select the better position by monitoring
the sound.
