Owner’s Manual
Since this instrument is equipped with two [PHONES]
jacks, you can connect two sets of standard stereo head-
phones. If you are using only one set of headphones,
insert a plug into either jack, shutting off the speakers.
CAUTION
Avoid listening to the instrument at a high volume level
through headphones for a long period of time, to prevent
hearing damage.
This function 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. Note that the I.A. Con-
trol is effective only from the sound output of the instrument speakers.
