14 System Overview
Each control head can be installed anywhere on a multi-drop line up to
2000m long (not included), and is powered locally by a mains-operated DC
plug pack. A speaker plugs into each control head to provide local Tx and
Rx audio.
Note
The DC Plug pack is not supplied as part of the kit. The correct
plug pack for each country can be ordered separately as per the
table on page
The control heads provide the same functionality as the standard T2000
control head, but will not provide for a DTMF module to be fitted. In
addition, the control heads provide some extra functions:
Global Mute
The Global Mute function is provided to avoid the possibility of
audio feedback when two or more control heads are placed in close
proximity. This function is individually selectable on each control
head, via a link JP1 on the control head PCB. Refer to Part B, Con-
trol Head for further information.
Power Switch Selection
The Power Switch Selection function is provided so that only one
control head in the system (the Primary control head) is able to con-
trol the system's power. This function is selectable by the fitting of a
jumper (JP2) on the control head PCB of the Primary control head.
Refer to Part B, Control Head for further information.
