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.
