Additional Functions of MTS 67/5
Control output - Control of external devices
Pin 4 is an open collector control output to control external devices.
When the microphone is activated the output is low-impedance to
chassis (Pin 1). The maximum current is 12 mA, the maximum voltage
is 55 V, total power dissipation 150 mW. If you want to connect
higher loads, this output can also be used for the control of an
additional switch.
Example:
If you connect the MTS 67/5 to the E 3300 mixing amplifier, the
current programme (e.g. music) can be faded out and the micro-
phone switched on for an announcement by pressing the micro-
phone button.
Control input - Control by external devices
The microphone unit can be controlled by an external control contact
connected to pin 5 (floating connection to chassis, pin 1). The operation
can be remotely controlled by an operator. Using the DIP switch located
on the underside allows you to select between remote control operation
(switch to "Remote control only") or microphone button and remote
control equally (switch to "Remote and internal control").
Example:
If you connect the MTS 67/5 to an operating console, video conference
or media control system the microphone unit can be switched on and
off centrally at the operation console, by the conference participant
or by the media control system.
Important!
To connect the MTS 67/5 us a cable with the following structure:
2 wires shielded (AF), 2 control lines and overall shield.
