Back of MIE-3XG Keyboard
Located on the back of the MIE-3XG Keyboard are a variety of jacks (as well as a
STANDBY/ON switch) that are essential to the accurate functioning of the keyboard in
the Music In Education System. Once set and connected, this part of the keyboard will
rarely be touched. To insure correct operation of the system, no student should be al-
lowed to touch this section of the keyboard.
Connect the MIE-3XG to external equipment only after turning off power for all de-
vices. To prevent damage to the speakers, set the volume of the external devices at the
minimum setting before connecting them. Failure to observe these cautions may result
in electric shock or equipment damage.
1: MIDI JACKS
The MIE-3XG Keyboard contains the standard MIDI IN, OUT and THRU jacks and can
run any standard MIDI application. In addition, the keyboard has a special MERGE IN
jack used only in the Music In Education System. See the “1. Quick Start Guide” sec-
tion for details on how to connect the MIDI cables to the jacks.
2: AUDIO IN JACKS
In the Music In Education system the AUDIO IN jacks bring sound from the teacher’s
keyboard and the computer to the student keyboard speakers and headphones.
3: AUDIO OUT JACKS
These jacks contain only the audio signal coming from the AUDIO IN jacks and thus
cannot be used to record the keyboard. (Use the headphone jack to record performanc-
es onto a tape or digital recorder.)
4: DC IN JACK
The external AC power adapter is connected here. This adapter should be used at all
times during normal classroom operation. You should never substitute any other kind of
adapter.
Never interrupt the power supply (e.g., unplugging the AC adapter) during any MIE-
3XG record operation! Doing so can result in a loss of data.
Use ONLY a Yamaha PA-5D AC Power Adapter (or other adapter specifically recom-
mended by Yamaha) to power your instrument from the AC mains. The use of other
adapters may result in irreparable damage to both the adapter and the MIE-3XG.
Unplug the AC Power Adapter when not using the MIE-3XG, or during electrical storms.
You should disconnect the power strip from the wall to accomplish this for an entire
MIE classroom.
5: STANDBY/ON SWITCH
The power switch should always be left turned on. While the system is in use, turning
this switch off will cause the software to stop functioning until the keyboards are reini-
tialized. In normal operation, the power to the keyboards (and the entire MIE system)
should be controlled from the wall outlet or main power strip.
Even when the switch is in the “STANDBY” position, electricity is still flowing to the
instrument at the minimum level. When you are not using the MIE-3XG for a long time,
make sure you unplug the AC power adapter from the wall AC outlet.
