KB-702/KB-702GM TWO-CHANNEL SPEAKER STATIONS

1-8

speaker or headset is controlled by the program level control. The program

input accepts a balanced or unbalanced line-level audio signal. If this input is

connected to the stage announce (SA) output of a main station it can be used

as a paging input. Since the level of this input is independently adjustable

from the intercom audio volume, it can be used to override the intercom

audio.

The pinout of the program input connector is as follows:

Pin 1 --- Ground (shield)

Pin 2 --- + Signal

Pin 3 --- - Signal

Figure 1-6: Program-Input Cable Wiring

18. Option Board Jumpers: The three jumper plugs P1, P2, and P3 must be

installed when optional modules are not used. When the optional EB7-4W

four-wire or EB7-TW modules are used, both P1 and P3 must be removed.

In the KB-702GM, P2 is replaced by the VOX module. Save these jumper

plugs for possible future use after removing them. The KB-702 will not

operate without either these jumper plugs or the optional modules

installed.
