Adjusting The Master Volume - Yamaha PortableGrand DGX-670 Owner's Manual

CAUTION
Even when the [P] (Standby/On) switch is in standby status, electricity is still flowing to the instrument at the
minimum level. Remove the electric plug from the outlet when the instrument is not to be used for extended
periods of time, or during electrical storms.
NOTICE
While recording or editing, or while a message is displayed, the power cannot be turned off even if you press the
[P] (Standby/On) switch. If you want to turn off the power, press the [P] (Standby/On) switch after recording, editing, or
after the message has disappeared. If you need to force-quit the instrument, hold down the [P] (Standby/On) switch for
longer than three seconds. Note that the force-quit operation might cause data loss and damage to the instrument.
Setting the Auto Power Off function
To prevent unnecessary power consumption, this instrument features an Auto Power Off function that
automatically turns the power off if the instrument is not operated for a specified period of time. The
amount of time that elapses before the power is automatically turned off is 30 minutes by default; however,
you can change the setting. For details, refer to page 18.
NOTICE
Any data which is not saved via the Save operation will be lost if the power automatically turns off. Make sure to save your data
before this happens.
 Disabling Auto Power Off (simple method)
Turn the power on while holding down the lowest key on the keyboard. A message appears briefly, then the instrument
starts up with the Auto Power Off function disabled.

Adjusting the Master Volume

To adjust the volume of the entire keyboard sound, use the [MASTER VOLUME] dial while playing the
keyboard.
CAUTION
Do not use the instrument for a long period of time at a high or uncomfortable volume level, since this can cause
permanent hearing loss.
Intelligent Acoustic Control (IAC)
IAC is a function which automatically adjusts and controls the sound quality according to the overall
volume of the instrument. Even when the volume is low, it permits both low sounds and high sounds to be
clearly heard. IAC Control affects only the sound output of the instrument speakers. You can turn the IAC
function on or off, and set the depth, although the default setting for this function is on. This can be set on
the Config1 tab in the Utility display called up via the [MENU] button (page 100).
