5 AUTO POWER ON/OFF switch

By setting this switch to the ON position, this unit’s

automatic power ON/OFF function operates as described

below. If you do not need this function, set to the OFF

position.

* Make sure to change the setting of this switch only

when the power of this unit is off.

Automatic power ON/OFF function

When you play a source, the power to this unit turns on

automatically by sensing audio signals input to this unit.

The power turns off automatically if the source being

played is stopped or the input signal is cut off for several

minutes.

* This function will operate responding to a certain level of

input signal. Increase the output level on the input

source if the automatic power ON function will not

operate, or decrease the level if the automatic power

OFF function will not operate.

* There may be a case that the power turns on

unexpectedly by sensing noise from other appliances. If

it occurs, set the AUTO POWER ON/OFF switch to the

OFF position.

This function is available only when the power of this

unit is on (by setting the POWER switch (

2) to “on”).

6 PHASE switch

Normally this switch is to be set to the normal (NOM)

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

reverse (REV) position. Select the better position by

monitoring the sound.
