    The goal of this text is to provide teachers with the practical functionality of all aspects of the GEC5 from a teacher’s perspective. I hope it will serve as a teaching resource as you begin managing your class with the GEC5.

    Hardware Overview The GEC5 lab system hardware consists of a single rack-mountable Teacher Unit and one Student Interface Unit per student workstation in your classroom. The Teacher Unit comes with an external power supply that you will plug into an electrical outlet and the Student Interfaces are powered by the Teacher Unit via Cat5 cables.

    Hardware Overview Teacher Unit Back: Volume Aux In 1 Power Examine the back of the Teacher Unit (see Fig. 2). You can connect up to 32 student stations to the back of the Teacher Unit using CAT5 cables (see #6). You do not need to connect all 32 stations; simply use as many student workstations as you have in your classroom.

    Be sure to connect to your wireless router through the wi-fi settings on your device. NOTE: The Apple AirPort Express and Apple AirPort Extreme are the recommended wireless routers for the Korg GEC5 system. See the Installation section of this manual for detailed instructions on setting up your AirPort Express/Extreme for use with the Korg GEC5.

    TIP: Using headphones with a built-in microphone is highly recommended to improve communication with students in the room. TIP: Current standard iPhone style headphones that include stereo headphones plus a mic do work with the GEC5! Simply connect the 3.5mm headphone cable into the headphone input on the Student Interface unit and you can hear audio output and use the headset microphone for student/teacher communication.

    Hardware Overview Student Interface Unit Back: Examine the back of the Student Interface units (see Fig. 4). (Fig. 4) Aux In 2: Most commonly you will connect the audio output of your computer or audio interface to this jack. If you are going directly from a student computer to the Student Interface, you will need a stereo 3.5mm male (out of your computer) to stereo RCA male (into Student Interface unit).

    Hardware Overview Mic Out: This jack sends the headset microphone audio out to any device. Most commonly, teachers will connect the Mic Out to a computer’s Audio Input or Mic In so students can record their voice into audio software such as Audacity.

    Set Up Overview The GEC5 is a very flexible system that can be used in a number of different learning situations with any combination of digital instruments regardless of brand. Both with and without computers, below, are some common lab situations using the GEC5: Keyboard and Piano Lab, Guitar Lab, Language Lab, and Multi-Purpose Technology Lab.

    Set Up Overview Wireless Teacher Workstation: This is the most common way to setup the teacher station. This setup provides the opportunity to use both the Mac/PC and tablet applications. When utilizing the tablet application, you can connect teacher headphones to the tablet’s headphone jack OR the Teacher Unit for audio playback.

  • Page 13

    Set Up Overview Once the Teacher Unit is set up, you are ready to connect the Student Interfaces to each station and corresponding instru- ment or computer, or both. Keyboard or Piano Lab: In this situation, you will connect the keyboard output to the Student Interface instrument input. See Fig. 12 for a detailed diagram.

  • Page 14

    Set Up Overview Keyboard or Piano Lab with Computer: In this situation, you will connect the keyboard output to the Student Interface instrument input jack and the computer audio output to the Student Interface Aux In 2 jack. You could also use an audio interface for computer audio output and connect the output of your audio interface to the Student Interface Aux In 2 jack.

    Guitar Lab: Connect an electric guitar to the input of a stand-alone guitar processor/external amp simulator (such as the Korg PXmini). Then connect the output that device to the Student Interface Instrument In jack. See Fig. 14 for a detailed diagram.

  • Page 16

    Set Up Overview Guitar Lab with Computer: Connect an electric guitar to the input of a computer audio interface and the output of the audio interface to the Student Interface Aux In 2 jack. In this situation you do not need to connect anything to the Student Interface Instrument In jack. See Fig.

  • Page 17

    Set Up Overview Language Lab: Connect the Student Interface Mic Out to the input of the computer audio interface. If you computer has a mic input jack, you may connect directly to the computer and skip the computer audio interface. Use software such as Audacity on your computer to record the audio output of the student headset microphones.

  • Page 18

    Set Up Overview Multi-Purpose Technology Lab: If your lab will be used for multiple purposes consider this setup. Essentially this is a combination of the 3 setups listed above and it would allow for the use of guitar, keyboard, and voice recording. See Fig. 17 for a detailed diagram. Front: Audio device (iPod, laptop, etc.) to Student Interface Aux In 1.

    Software Control Application TIP: Setting a class up in split mode allows the GEC5 system to accommodate 2 students per station, sharing a single keyboard. For the best results, you’ll need keyboards that are programmed with Korg’s GEC5 Split programs. These presets split the audio from the keyboard down the middle so that only the student on the left will hear notes below Middle C, and the student on the right will only hear the keys above Middle C;...

    Installation Positioning the Teacher Unit: The Teacher Unit should be placed near the teacher instrument and close to external audio devices and the room amplifier, for ease of use. The unit can sit on a desktop or be rack-mounted. Connect Cabling: Once all equipment is in place, you are ready to lay down the wiring that will connect all lab equipment: Start with the AC cabling.
