Installation 

 

 

89 

 

• 

If the teacher workstation includes a stereo cassette recorder, auxiliary audio source (like 
a CD player/burner), or additional MIDI sound sources, connect the equipment at this 
time.  Be sure to route all signals in stereo, or split the signal using an appropriate cable 
or adapter. 

• 

If the GEC3 is to be connected to an external amplification system, connect the Room 
Outs to the amplifier, receiver, or powered monitors at this time.

 

Of particular concern are the AC, audio and communications (modular) cabling runs 
themselves.  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.   

More on the Communication Cables 

In configuring a 

GEC3 learning System

, the only non-standard cables integral to installation 

are the 

Communications Cables

.  These are Ethernet, eight conductor cables (category 3 or 

5). 

GEC3 Communication Cables 

can be purchased in two ways: 

Korg supplies three lengths of 

Communications Cables

,

 CC-14/25/33

, in fourteen, twenty-

five, and thirty-three foot lengths. 

When permanently installing a large 

GEC3 Learning System

, the purchase of a s pool of 

category 3 or 5 cable, connectors, crimping tool, and cable tester may be preferable.  Material 
specifications are listed below and the cable, connectors, and crimper can be purchased from 
any computer network or cable wholesaler: 
 

1.  Cable: eight-conductor category 3 or category 5 

2.  Connectors: RJ-45 type 

3.  Crimping: RJ -45 type 

 

Note:  

If you are not experienced in network installation, Korg U.S.A. recommends that you 
purchase the 

Communications Cables

 noted above or that you contact a local professional 

who has experience in network installation.
