Top & Front of MIE-3XG Keyboard (Continued)

Stereo headphone jacks are located on the front left and right corners of the key-
board. Headphones should always be left plugged in to avoid wear on the head-
phone jacks. MIE-3XG headphones will always output sound when connected, 
and do not need to be unplugged for the speakers to work. See the “Modes Chart” 
for a complete description of headphone operation in the four different modes.

A Keyboard Split Divider fits over the center octave and should be used in Split 
and Ensemble modes to provide each student with an identical two-octave key-
board. 

   

Speakers are located at the upper left and right corners of the keyboard. Sound 
coming from the speaker can be turned on or off by pressing the speaker button 
adjacent to the speaker. Speaker sound can also be controlled by the MIE soft-
ware. The teacher can monitor an individual student using headphones by turning 
on his/her respective speaker button. See the “Modes Chart” for a complete 
description of speaker operation in the four different modes

This button is located above the keys on both sides of the keyboard. It allows the 
students to respond during quiz and review activities.
