TROUBLESHOOTING

The purpose of technology in the classroom is to improve instruction. I simply don't believe in technology for the sake of technology. When looking at a piece of music tech gear, I'm always trying to evaluate and develop ways to use the gear as a tool to teach a musical concept in a more efficient and/or interesting manner. Music technology, in particular, has the ability to make musical concepts more accessible to students and can serve as the "on ramp" to a lifelong appreciation of music. Sure, any student can drag in loops to make a beat using music production software, but in my classroom I use loops to teach the concepts of form and texture. The piano keyboard is often an intimidating piece of music making equipment, however, by starting with some simple percussion rhythm, venturing to a 2-note bass line, and finally playing notated melodies, students can slowly get their feet wet and eventually feel comfortable playing on the keyboard.

Some pieces of gear go beyond teaching a concept and actually allow a classroom to function. Over my 13 years of teaching music technology both in high school and higher education, the one indispensable piece of gear that makes my classroom work is the Korg GEC. Administrators are always amazed at how quiet my classroom is and how efficiently I can address student needs and differentiate my instruction. Students can work independently, interact 1-on-1 with the teacher, share audio with the class, and work collaboratively with a peer. The GEC is the audio nerve center of my classroom and provides the perfect teaching environment for all audio-based activities.

The GEC has steadily improved over the years and the new GEC5 is a dramatic upgrade. The GEC5's rack-mounted Teacher Unit and a computer/tablet application provide a much more user-friendly environment. With the addition of a wireless router, the teacher can manage the classroom while walking around the room with an iPad or Android tablet. Students no longer need proprietary T4 headphone connections and can instead use standard 3.5mm jack headphones (including iPhone style headphones with microphones!).

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. I will start with a brief overview of the student interface units, rack-mounted Teacher Unit, and how to make all of the connections. Next, I will delve into the software that controls the GEC5. The GEC5 Controller application is available for Mac/Windows and iPad/Android tablets. Finally, I will conclude with an appendix discussing the layout of the lab, a site plan checklist, and step-by-step instructions on how to install the Korg GEC5 system. Throughout the text, I include numerous TIP boxes that offer real-world advice from my years of working with the GEC Learning System in the classroom.

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.

Teacher Unit Front:

Examine the front of the Teacher Unit (see Fig. 1). With the exception of the Call Button, the Teacher Unit front is very similar to the Student Interface Unit front.

KORG GEC5 Worker set Powerless in line

(Fig. 1)

1. Headphone Input: Connect the teacher headphones here for audio playback and microphone communication. Similar to Student Interface Units, teachers can connect any standard 3.5mm headphones to the Headphone Input jacks. If the headphones include a microphone (such as the Koss SB40 headphones), connect the 3.5mm mic cable from the headphones to the microphone input jack. It is especially important for the teacher to have a headset with attached microphone to improve hands-free class communication.
2. Volume Knob: Rotate the knob clockwise to increase the overall volume in the teacher headphones. Rotate the knob counter-clockwise to decrease the overall volume.

NOTE: The teacher volume knob does not impact the volume output of the teacher microphone or Aux inputs to the students. In other words, if the teacher increases the volume with the volume knob it will only impact the volume to the teacher headphones and this will have zero impact on the volume of teacher devices to the student stations.

1. Aux In 1: This is a stereo input to connect any external device such as a laptop, tablet, or MP3 player.

TIP: Connect a stereo 3.5mm male to stereo 3.5mm male cable and leave this connected at all times. Teachers can then easily incorporate sound from an external device and broadcast this sound to all student workstations without having to reach to the back of the Teacher Unit. I suggest keeping this cable connected to a device (MP3 player, iPod, laptop, etc.) at all times to avoid unwanted noise.

1. Power: Toggle the switch to turn the power on or off.

TIP: I suggest shutting down the Teacher Unit when it will not be in use for an extended period of time. I usually turn the Teacher Unit on first thing in the morning and off at the end of my teaching day.

TIP: Be sure to turn off your classroom speakers and/or the power amplifier for your speakers before turning off the Teacher Unit. This will avoid popping sounds from your speaker that can damage your speakers over time. Generally, turn the speakers and/or power amp ON last and OFF first.

Teacher Unit Back:

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.

(Fig. 2)

1. Power: Connect the AC adapter to the power jack. Connect the included 3-prong cable to the AC adapter and then into a standard 3-prong wall outlet.

TIP: The 3-prong cable is a standard cable that often comes with other electronic devices such as monitor speakers and computer towers. These cables are interchangeable.

1. Instrument Input: Connect your teacher instrument to this input. You will mostly likely need dual TS male 1/4" (out of your instrument) to dual TS male 1/4" (into Teacher Unit). Be sure to check the user manual of your instrument to confirm the proper cabling for your specific device.

2. Aux In 2: This is a stereo input to connect any external device to the Teacher Unit. Most commonly you will use this jack for the teacher computer or audio interface. If you are going directly from the teacher computer to the Teacher Unit, you will need a stereo 3.5mm male (out of your computer) to stereo 3.5mm male (into Teacher Unit). If you are using an audio interface you will mostly likely need dual TS male 1/4" (out of your interface) to stereo 3.5mm male (into Teacher Unit). Be sure to check the user manual of your audio interface to confirm the proper cabling for your specific device.

3. Room Out: Connect your room speakers to this jack.

a. If you have active (self-powered) speakers, use two cables (for Left/Right stereo sound) with a balanced (TRS) 1/4" (into Teacher Unit Room Out) to the required input of your active speakers. Most commonly your active speakers will require a balanced (TRS) 1/4" male or XLR male cable.

b. If you have passive (unpowered) speakers, use two cables (for Left/Right stereo sound) with a balanced (TRS) 1/4" (into Teacher Unit Room Out) to the required input of your power amplifier. Most commonly your power amplifier will require a balanced (TRS) 1/4" male or XLR male cable. Then, connect your power amp to your passive speakers.

TIP: Turn your power amp or active speakers ON last and OFF first to avoid pops.

1. Record Out: This jack allows you to record the overall output of the Teacher Unit. Use two cables (for Left/Right stereo sound) with a balanced (TRS) 1/4" (into Teacher Unit Record Out) to the required input of your recording device.

TIP: Use this Record Out jack to capture live recordings of student performances. Save the file as an MP3 and build digital portfolios of student work for assessment.

TIP: There are many options for recording. Here are a few suggestions:

• Use any portable digital recording device to capture the audio. These devices often record to an SD card and can store many hours of MP3 audio. There are many makes/models of portable digital recording devices currently available at very affordable prices. Be sure to take note of the inputs available on your portable digital recording device (some use 3.5mm jacks while others use a pair of 1/4" jacks) and connect with a cable with the corresponding end.

• Connect directly to a computer audio interface using Aux Inputs 1 or 2. Record the audio using music production software such as Audacity (free download).

• Student Interface Inputs: Using CAT5 cables, connect each Student Interface Unit to the Teacher Unit station inputs (1-32). Be sure to connect student workstation 1 to Teacher Unit station input 1, and so forth.

TIP: Label each CAT5 with the student station that it is connected to in the event that you need to disconnect the Teacher Unit. I suggest labeling the CAT5 cable on both the Teacher Unit end and the Student Interface Unit end.

7. Network:

Wireless configuration: If you are going to use the iOS or Android app or just want to connect to the Teacher Unit wirelessly through your Mac/PC computer app, you will need a wireless router. Connect a CAT5 cable from the Teacher Unit network jack to your router's LAN ports (this is NOT the internet input on the router). 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.

• For more information on the Apple AirPort Express visit: http://www.apple.com/airport-express/
• For more information on the Apple AirPort Extreme visit: http://www.apple.com/airport-extreme/

TIP: To have internet access while using the wireless configuration, connect your internet connection cable to the wireless router's internet input.

TIP: Remember to check your devices wi-fi network and confirm that it is seeing the wireless router connected to your Teacher Unit. The wi-fi network can change when you restart your device, walk out of range of the wireless router, or a variety of other reasons. Check the selected wi-fi network FIRST when you are troubleshooting a GEC5 issue. If you lose connectivity, your GEC5 application will display a screen indicating that it is searching for your GEC5.

TIP: I strongly suggest using the wireless configuration. This gives the teacher flexibility to use the Mac/PC app or tablet app since they both access the same wireless router.

Wired configuration: If you are only going to use the Mac/PC app simply connect a CAT5 cable from the Teacher Unit network jack to your computer's Ethernet jack. NOTE: It can take 1-3 minutes for the computer application to recognize the GEC5 in this configuration if you do not have an active internet connection connected to the other Teacher Unit network jack.

TIP: Although I prefer to have both GEC5 access AND internet access on my device while working the GEC5, it is perfectly fine to use and operate the GEC5 as a stand-alone unit with no internet connectivity.

Student Interface Unit Front:

Install a single Student Interface Unit at each student station. You do not need a Student Interface at the teacher station. These Student Interface Units can be mounted with screws either on top of or below the desk depending on what works best for your situation.

TIP: When mounting each Student Interface to the student workstation, be sure to set them back about 1-2" to allow for the cable heads. If the Student Interface is set even with the desk, the cable heads will stick out and be subject to much more wear-and-tear and this will inevitably shorten the life of the Student Interface Unit jacks and headphone cables.

TIP: You can also mount the Student Interface to stations using Velcro. I've seen some teachers apply Velcro to the bottom of the Student Interface unit and the top corner of the keyboard at each student workstation.

Hardware Overview

GO TO WEBSITE

1. Call Button: Students will press this button whenever they need to get the teacher's attention.

TIP: I ask my students to press the Call Button whenever they have a question or want to play/perform a completed assignment for me.

TIP: Get students comfortable pressing the Call Button for help from day 1. In my music production classes, I invite students to share their first project with the class and I offer bonus points for doing so. Any student who would like to share and earn bonus points must press his/her Call Button to alert me during our sharing time. This gets students comfortable with sharing as well as making use of the Call Button.

1. Aux In 1: This is a stereo input to connect any external device such as a laptop, tablet, or MP3 player.

TIP: Connect a stereo 3.5mm male to stereo 3.5mm male cable and have this cable available for student use at all times. Students can then easily incorporate sound from an external device without switching headphones.

TIP: Consider posting custom accompaniment files to a website for students to access on their personal devices. For example, a student could download an accompaniment for a piano exercise on his/her iPhone, connect the device via the Aux In 1 input, and then play along with the accompaniment using the lab keyboard.

1. Headphone Input 1 and 2: This is where students connect headphones for audio playback. Students can connect any standard 3.5mm headphones to the Headphone Input jacks. If the headphones include a microphone (such as the Koss SB40 headphones), connect the 3.5mm mic cable from the headphones to the microphone input jack.

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.

1. Volume Knob: Rotate the knob clockwise to increase the overall volume of the station. Rotate the knob counter-clockwise to decrease the overall volume.

TIP: I suggest turning the volume mostly all the way up on your external devices (keyboard, computer, audio interface, other audio device, etc.). Then slowly increase the overall volume using the Student Interface Volume Knob. This will reduce the presence of system noise.

Student Interface Unit Back:

Examine the back of the Student Interface units (see Fig. 4).

1. 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). If you are using an audio interface you will mostly likely need dual TS male 1/4" (out of your interface) to stereo RCA male (into Student Interface unit). Be sure to check the user manual of your audio interface to confirm the proper cabling for your specific device (see Fig. 5).

1. Instrument In: Connect your keyboard/instrument to this input. If your keyboard/instrument has a Left and Right audio output, you will most likely need dual TS male 1/4" out of your keyboard/instrument to stereo RCA male into Student Interface unit (see Fig. 6). If your keyboard/instrument only has a single audio output, you will most likely need a single TRS male 1/4" to stereo RCA male cable (see Fig. 7). Be sure to check the user manual of your keyboard/instrument to confirm the proper cabling for your specific device.

(Fig. 7: TRS male 1/4" to RCA male cable)

1. 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. Using an 3.5mm TS male to 3.5mm TS male cable, connect one end into the Mic Out jack on the Student Interface and connect the other to your computer's audio input (see Fig. 8). If you are using an audio interface to cable the microphone audio, you will likely need a 3.5mm TS male (to Student Interface) to 1/4" TS male (to audio interface) cable (see Fig. 9).

1. Network: This all-important jack connects each Student Interface Unit to the main Teacher Unit at the teacher station. Use a CAT5 cable to make this connection.

TIP: Since each Student Interface Unit is hard-wired to the Teacher Unit, it is important to plan the layout of the room prior to installation. It is difficult to move stations more than a few feet after installation and it could require you to re-cable individual stations. I would also suggest working with your janitorial staff so they know not to move stations from their current location. If you ever need to move a station, label each CAT5 cable with the name of the station and unplug it from the Student Interface Unit before moving.

Installing the Application:

Now that you have completed your hardware set up in your lab, it's time to configure the GEC5 Software Control Application for your new lab. The Teacher Unit will act as a server for the room and save any customizations you make along with setting up Teachers, assigning Classes and even creating presets. The Korg GEC5 Software Control Application is available for any desktop or laptop using a Windows or Mac operating system or tablets using iOS or Android. Because the Teacher Unit saves the information you input for your room set up, you can transition from desktop to tablet with ease.

First, choose the device option that fits your needs best and follow the download instructions provided online:

Room Setup:

Once you have the application installed on your device, you are ready to really begin using the GEC5. Be sure that all cables are securely connected (especially all CAT5 cables) and the Teacher Unit is powered on. Launch the application from your device. The very first time you launch the application, you will go through a brief room setup. If the application does not find your GEC5 hardware, quit the application, recheck your CAT5 connections, verify the power to the Teacher Unit is on, and re-launch the application. Follow the on-screen prompts to setup your virtual room in the GEC5 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; both halves of the keyboard are transposed so that they are in the same middle octave, as well.

These Korg Split Programs, along with the Split Station capability of the GEC5 system, will allow the two students to function completely independently, and the teacher will have all the same audio functionality as if the students were at separate keyboards. Split Station mode is ideal for labs where space restrictions are a factor, as it essentially allows you to have double the number of keyboard students as you have keyboards.

NOTE: You must load specialized Korg Split Sounds into your Korg keyboard to make use of the Split feature.

TIP: In the application, you will see a thin red bar at the bottom of any student stations that are not recognized by the GEC5 system. Check to make sure all CAT5 cables are securely connected. You can also try restarting the application and/or the Teacher Unit. If the problem persists, try replacing the CAT5 cable.

Call Button:

(Fig. 35)

The Call Button exists on each Student Interface Unit. When students press the Call Button, the student station on the GEC5 application screen will light up yellow (see Fig. 35). To answer the call, double-click twice on the student station. To remove the yellow tag, double-click again. You can also press the Clear All Calls button in the lower left corner to clear off all calls at once.

Lecture Mode:

(Fig. 36)

To access Lecture Mode, click the Lecture icon at the bottom of the screen (see Fig. 36). Lecture Mode is used when you (the Teacher) want to present material in a lecture format. Students hear the Teacher Station output plus their own station. To mute all student station sound while in Lecture Mode, click the "Student Instruments" icon in the bottom right corner of the application. This icon will turn gray indicating that all students hear the teacher microphone, instrument, and Aux devices (such as the teacher computer) ONLY.

You can also bring students into the lecture so they can be a part of the presentation by double clicking (see Fig. 37). A blue headset icon will appear next to the student's name and they are now broadcasting their station's audio to the class (mic, instrument, Aux devices).

(Fig. 37)

TIP: My most common uses for Lecture mode include:

• Students playing along with the Teacher. I use this mode for a class warm-up or to introduce a new song.
• Teacher lecture. I use this mode if I want to address the entire class and instruct from the front station.
• Students share/perform for the entire class. Simply double-click one or more students to allow those students to broadcast their work to the entire class. Students can share a completed project or piano song with their peers. Consider hosting a virtual recital using the GEC5...and record it with the Record Out feature on the back of Teacher Unit using a hand-held recorder or computer software!

Note: Students can perform duets, trios, quartets, etc. for the class by clicking on more than one student in Lecture Mode. To practice duets, trios, quartets, etc. you will use Group Mode (discussed later in this section of the text).

Practice Mode:

(Fig. 38)

To access Practice Mode, click the Practice icon at the bottom of the screen (see Fig. 38). Practice mode is used when the students are working independently. Each student hears only his/her own instrument. You have the option of hearing the student, or hearing and speaking with the student.

To eavesdrop on a student, double click the student station. You will see a headphone icon without a microphone (see Fig. 39).

(Fig. 39)

To communicate 1-on-1 with a student, double click the student station again. You will now see a headphone with microphone icon (see Fig. 40).

(Fig. 40)

TIP: My most common uses for Practice Mode include:

• Individual student practice time. Students can work on their material in a quiet classroom setting.
• Eavesdropping. As the teacher, I can monitor student progress to help manage my class and keep students moving ahead on class material.
• 1-on-1 student/teacher interaction. 1-on-1 communication is my favorite aspect of the GEC5. I get a chance to talk to each and every student on a daily basis throughout class. I can also answer questions and check completed assignments/projects extremely efficiently.

Group Mode:

(Fig. 41)

To access Group Mode, click the Group icon at the bottom of the screen (see Fig. 41). Group mode is used when you want to allow students at different workstations to work together. Group Mode allows you to define groups of two or more student workstations so they can collaborate on projects with complete audio capabilities. Each student hears their own instrument and the mic(s) and instrument(s) of the other students working in their assigned group. You have the option of eavesdropping on the groups or having 2-way communication with them.

To group students using the existing Auto Group presets:

1. Click the "Recall Preset" icon (see Fig. 42).
2. Select one of the Auto Group presets (Duet, Random Duet, Quartet, Group All, and Ungroup All).
   a. Duet: Groups are automatically created for stations 1/2, 3/4, 5/6, etc.
   b. Random Duet: Each time you click on Random Duet, the GEC5 groups

TIP: Since Group All has ALL students sharing all sound output, I would only suggest using this preset with small classes or when each student has a clear task. I do NOT suggest using this preset for sharing class projects. Use Lecture Mode instead.

To group students into custom groups:

1. Click and hold on a student station until it turns blue.
2. Continue to click and hold on additional students so multiple students are blue (see Fig. 43).

All Call:

(Fig. 46)

All Call is available in Practice and Group mode (see Fig. 46). Press it to route signal from the teacher mic to every headphone set connected in the studio or classroom. This is the quickest way to establish communication with the students in Practice or Group mode.

By pressing the All Call button, you turn off all student instrument and voice audio, and students will only hear you (the Teacher) and your instrument. All other selections and button presses (like student box, two way communication, etc.) are disabled.

TIP: My most common uses for All Call include:

• To avoid distraction during a lesson lecture. Since All Call mutes the student station audio, I can be sure the students are focused on my instruction and not distracted by any other audio source from their own station.
• To signal a transition to a new topic or activity. As students are working in Practice or Group mode, I will often use All Call to quickly mute all student sound and pivot to a new activity. Example: Students are working on the melody to piano piece in Practice Mode. After 15 minutes, I press All Call and instruct the students to pause their practicing while we discuss the music theory concepts behind the chord progression for the piano piece. I'm always amazed at how quickly the students look up when I press the All Call button!

When installing your music or language lab, adhere to local building and electrical codes. If you are not familiar with local building regulations for the installation of electrical equipment in your school or studio, seek assistance from maintenance personnel, electrical contractors, and/or local government (county or township) offices for information.

The Planning Stage:

The more time and thought you give to planning your music or language lab, the fewer problems you are likely to face when installing and using it in a teaching situation. The checklist below will assist you in preliminary planning. We recommend that you use the checklist to design a teaching environment that will meet your needs.

Before you begin, consider the following:

• Allow for future expansion: If possible, leave sufficient room for additional equipment and cabling. The GEC5 allows for easy expansion of additional student stations, up to 32 total.
• When planning teacher and student workstations, don't forget that some instruments are freestanding and others require stands, which add to their length, width, and/or depth.
  • Take into account student sight lines. It will be important for students to see the Teacher, LCD projector screen, whiteboard, and other teaching aids.
• If students are to work and perform in duets, quartets, or customized groups, make an effort to place
  student keyboard/workstations so that students within groups can easily establish eye contact.
• Ensure that the teacher can easily access his or her instrument, as well as external audio equipment (such as additional instruments, computer/keyboard, digital recorders, CD players/burners, etc.).
• Position the room speakers so that the Teacher, as well as the Students can hear them

Site Plan Checklist:

1. Diagram the dimensions of the physical site where the GEC5 will be located. Make sure that the diagram is drawn to scale.
2. Note on the diagram the placement of all doors, windows, AC outlets, and Ethernet drops (if there will be computers using a wired internet connection).
3. List the equipment that will be used by the teacher including the Teacher Unit, teacher's instrument, any additional MIDI devices/instruments, computer, and audio accessories such as tape decks, CD players/burners, stereo amplifier/receiver, self-powered monitors, and/or speakers.
4. How many student stations will the lab contain?
5. List the equipment that will be used by each student.
6. What are the approximate dimensions of each student station? Include the student bench or chair, allowing sufficient space between the instrument and bench for the student to be seated comfortable and for the teacher and other students to walk between stations.

TIP: I suggest using seats with backs. Students often find piano benches without backs rather uncomfortable if the class lasts more than 30 minutes.

1. Draw to scale a diagram of teacher and student workstations, as well as all additional audio and/or MIDI accessories.
2. Once the teacher station and student stations are positioned in the diagram, add AC and CAT5 Cable routings. Finally, add the cable routings for the audio accessories (such as tape decks, CD players/burners, stereo amplifiers, etc.).

Cabling Estimates and Requirements:

Here are the different kinds of cable that will be essential to the lab installation:

1. AC Cable: carries electrical current to all devices. Be sure that there are enough grounded AC outlets to accommodate the teacher and student stations. The installer must check with the school regarding power requirements, use of extension cords, fire code, etc. to insure that the lab adheres to code. The GEC5 Student Interface Unit does not require an AC outlet, but instruments and computers will.
2. Audio Cable carrying:
   a. Signals from the teacher's instruments and external audio equipment to the Teacher Unit.
   b. Signals from the Teacher Unit to an amplifier (or powered monitors) and a digital recorder.
   c. Signals from the student instruments and student computers to the Student Interface Units.
3. CAT5 Communications Cable: carries audio and communication signals between the Teacher Unit and the Student Interface Units. You will also need CAT5 cable to connect your computer and/or wireless router to the Teacher Unit for GEC5 Controller Application functionality
4. Speaker Cable. If your monitors are not self -powered, you will also require speaker wire to carry audio signals from the room amplifier (which may be a standard stereo receiver) to the room speakers. This wire should be of the heaviest gauge practical.

Sizing Cables:

The placement of the equipment in your lab will determine the lengths of cabling required. In order to select the appropriate lengths of communications cable, measure the distance from the Teacher Unit to the floor, floor distance from teacher station to student station, floor to Student Interface, and include an additional twelve to twenty-four inches for movement and slack.

Positioning Equipment:

Begin your installation by:

1. Positioning the teacher and student stations in accordance with your site plan.
2. Placing all audio accessories in their designated areas.
3. Positioning the Teacher Unit and each Student Interface Unit.

Mounting the Student Interface Unit:

Each Student Unit Interface should be mounted on or near the student instruments, making it easier for students to access volume controls and call buttons. This will also minimize the length of audio cables required between student instrument and Student Interface Unit.

Position Student Interface Units so that student headset cables will not be in the way, inhibiting students' natural movement in playing. Position the Student Interface units 1"-2" back from the table edge to help protect the headphone jack and headphone cable from accidental damage. Student Interface units may be attached to desks or wooden tables using wood screws or on top of desks/keyboards using Velcro.

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:

1. Start with the AC cabling.
2. Next, connect the audio and CAT5 cables at both teacher and student stations.

a. Having permanently mounted the Student Interface units to or near the student instruments, connect all student instrument outputs to the Student Interface inputs.
b. If the student workstations include a computer or other auxiliary devices, connect the audio signals to each Student Interface unit's auxiliary input. Also connect the Mic Out on the back of the Student Interface unit to the student computer's audio input.
c. Connect a CAT5 cable from the Teacher Unit to each Student Interface Unit.
d. Connect the teacher instrument output to the Teacher Unit's instrument inputs.
e. Connect the audio signals from the teacher computer or other auxiliary devices to the Teacher Unit auxiliary inputs.
f. Connect the audio signals from the Record Out jack on the back of the Teacher Unit to any digital recording device or computer audio interface.
g. If the Teacher Unit is to be connected to an external amplification system, connect the Room Outs to the amplifier, receiver, or powered monitors at this time.
h. Using CAT5 cables:

i. Connect your internet cable to one of the network jacks in the back of the Teacher Unit.

ii. Wired: Connect the computer's Ethernet jack to one of the network jacks in the back of the Teacher Unit.

iii. Wireless: Connect your wireless router's Ethernet jack to one of the network jacks in the back of the Teacher Unit.

TIP: In the interest of neatness and in order to avoid potential accidents, you should use many cable ties. In order to minimize potential interference, always try to keep AC, audio, and communications cables as far apart as possible, always attempting to avoid parallel runs. In addition, avoid exposed and/or loose cabling, avoiding cable runs across walkways and aisles.
