4.0 Installation

4.1 Electrical connections

Although the FreeSpace

system controller accepts balanced and unbalanced sources,

balanced sources provide better audio performance. Observe proper polarity when

making connections:

• The positive terminal is usually the high, tip, or plus (+) terminal, or pin 2.

• The negative terminal is usually the low, ring, or minus (–) terminal, or pin 3.

• The ground terminal is usually the shield, sleeve, or ground (

) terminal, or pin 1.

Note: The ground terminals are NOT safety grounds. They are for audio signals only. Do

not use these terminals as a substitute for a proper safety (earth) ground for this equip-

ment or other equipment connected to it.

From microphone or paging source

(Figure 6):

1. Connect the positive and negative terminals to the positive and negative terminals on

the controller.

2a. If the source has balanced outputs, connect the ground terminal to the ground

terminal on the controller.

2b. If the source has unbalanced outputs, connect the ground terminal on the controller

to the negative terminal on the controller. This will help prevent unwanted noise.

CAUTION

Unplug all components before

making connections.
