Prepare the Room
Before installing an GLC-1 music conferencing system, there are many factors to consider. For example, the size and shape
of the room, the availability of lighting and power outlets, and the ventilation and temperature control of the room all need
to be addressed. Please consider the following physical and electrical requirements before installing the GLC-1 music
conferencing system.
Physical Requirements
• Create an effective floor plan that ensures a clear “line-of-sight” from all student stations to the teacher station. While
this isn’t always possible due to the constraints of a given room, it’s a worthwhile setup goal.
• Be sure that there’s adequate space behind each student station so that the teacher can move easily from station to station.
• Use anti-static, or static-resistant, carpet on the floors whenever possible to lower the noise-level in your lab and reduce
damage created by static electricity.
Electrical Requirements
• Once the floor plan is defined, determine the number of electrical outlets and power strips needed to supply power to
all devices. Isolate the GLC-1 Hub from devices such as computers or lights by plugging the devices into separate 120v
wall plug receptacles. Plugging computers or rheostatic lights into the same receptacle as the GLC-1 Hub could cause
disturbing noise and hum during operation. Use only the supplied AC power adapter; other AC adapters can
damage the unit and void the warranty.
• Use surge protectors on all electronic equipment in the music lab. This includes the GLC-1 Hub, the teacher’s instrument
(and computer), student instruments, and all external audio devices. Check the voltage and amperage requirements of the
equipment being installed and consult with the building engineering staff regarding the level of electrical service required.
• Set the main power switch on the GLC-1 to the Off position before connecting the AC power adapter to a 120v
wall plug receptacle. Use only the AC power adapter supplied with the Music Tutor Lab Controller; other AC adapters
can damage the unit and void the warranty.
• For further protection against electrical surge damage, disconnect all AC power adapters from the wall plug receptacle
during school vacations or summer breaks.
