3.6.2 Headset Socket (DIN 5)

The 5 pin DIN Headset Socket is used to connect an optional headset for use when the optional

microphone and loudspeaker are not required.

(Headsets should be used in areas where a number of control panels are used in close proximity, this

should avoid any possibility of howlround (audio feedback) occurring).

3.6.3 Direct Access Key (DAK)

The 4000 Series Panels have Direct Access Key (DAK) pushbuttons. These DAKs are used to make

Listen and/or Talk routes to and from the Control Panel or other audio connections. The DAK can also

be assigned to trigger a control (logic) action.

The pushbutton operation is selectable from a range of options and set via the Configuration and Master

Assignment Programming System (CMAPSi) workstation software. The pushbutton actions include:

Vitec Group Communications can offer three different types type of microphones -

100mm, 340mm and 490mm goosenecks.

All panels are available with DIN 5 headset connection.

Table 9: PD4224 DAK Operation

Latch When a DAK is pressed and released, it latches in the engaged position.

Pressing the DAK again disengages it.

Non-Latch When a DAK is pressed and held depressed, it automatically disengages

when released.

Latch/Non-Latch A combination of the two above such that a quick press will latch the but-

ton and a slow press will be the non-latch action.

Dual Talk/Listen When a DAK is momentary pressed, it makes a latched Listen Route.

The DAK can then be pressed and held to make a Talk Route at the

same time, and released to unmake the Talk Route. A second momen-

tary press disengages the DAK and the latched Listen Route.

Interlock Group A DAK can be assigned to any one of eight interlock groups A - H. Within

an interlock group only one DAK may be active at any one time. If a DAK

in a given group is pressed whilst another DAK in the same group is

already active the currently active key is deactivated and the key pressed

becomes active.
