Connecting Headphones Or An External Speaker ([Phones/Output] Jack); Connecting A Microphone ([Mic Input] Jack) - Yamaha PortableGrand DGX-670 Owner's Manual

Connecting Headphones or an External Speaker ([PHONES/OUTPUT] jack)

The [PHONES/OUTPUT] jack can be used to connect headphones, as well as for sending the output signal
to the connected device, such as a speaker, recorder or computer. The speakers of this instrument are
automatically shut off when a plug is inserted into this jack.
CAUTION
Do not use the instrument/device or headphones for a long period of time at a high or uncomfortable volume level, since this can
cause permanent hearing loss.
Instrument
Standard stereo
phone plug (1/4")
NOTICE
• To avoid possible damage, first turn on the power to the instrument, and then to the external device. When turning off the
power, first turn off the power to the external device, and then to the instrument. Since this instrument's power may
automatically be turned off due to the Auto Power Off function (page 17), turn off the power to the external device, or disable
Auto Power Off when you do not intend to operate the instrument.
• Do not route the output from the [PHONES/OUTPUT] jack to the [AUX IN] jack. If you make this connection, the signal input at
the [AUX IN] jack is output from the [PHONES/OUTPUT] jack. These connections could result in a feedback loop that will make
normal performance impossible, and may even damage the equipment.
NOTE
Use audio cables and adaptor plugs having no (zero) resistance.
Reproducing a Natural Sound Distance Sensation (even when using Headphones)—
Stereophonic Optimizer
The Stereophonic Optimizer feature recreates for headphones the spacious sensation you hear when you
play an acoustic piano. In general, the sound from headphones is much too close to your ears for natural
sound. When this function is turned on, you can sense a natural sound distance as if the sound is coming
from the piano, even though you hear it on headphones. This function is effective only on the VRM Voices
(page 41) and does not affect the sound output of the instrument speakers. The default setting of this
function is on. You can turn it on or off via [MENU] → Cursor buttons [
TAB [ ] Config1 → Cursor button [
