5.  Installation
5.1  Rack installation 
Each device requires one rack unit for installation in a 19" rack. Please allow an 
additional 4" of rack depth for the rear panel connectors.
Be sure that there is enough air space around the unit for cooling. To avoid 
overheating, do not place the unit on power amps, for example.
5.2  Audio connections
You will need a large number of cables for the different applications. 
The illustrations below show the wiring of these cables. Be sure to use only 
high-grade cables.
The audio connections of the MULTICOM PRO-XL, AUTOCOM PRO-XL and 
COMPOSER PRO-XL are electronically balanced to avoid hum problems.
You can, of course, also connect unbalanced devices to the balanced inputs/
outputs. Either use mono plugs, or link the ring and shaft on stereo plugs 
(or pins 1 and 3 in the case of XLR connectors).
For unbalanced use, pin 1 and pin 3 have to be bridged
1 = ground/shield
2 = hot (+ve)
3 = cold (-ve)
