TOGGLE OPERATION (PUSH TO TALK)

TOGGLE OPERATION (PUSH TO TALK)

Let's say that you want MX392 to be muted by default. If someone pushes the membrane switch, you want the microphone to stay unmuted until the user presses the switch to mute the microphone. You also want the LED to illuminate when the microphone is unmuted.

First, set DIP Switch S1, S2, and S3 to ON and set S4 to OFF. Then, connect SWTICH OUT to one of the Logic Input pins 1-24. Connect LOGIC GND to Logic Output pins 21-25. Connect LED IN to one of the Logic Output pins 1-20.

DEFAULT CONDITIONS

First, you want to make sure that the Vortex Device has all microphones muted as part of the Power on Preset. Next, you need to make sure that if the unit is controlled by a control system that the proper commands are sent to the Vortex Device to mute the microphones when the room is used for conferencing or sound reinforcement purposes. Remember that since the requirement is push to talk, the user of the microphone is the one that must initiate the activity of unmuting the microphone.

LOGIC INPUT

Go to the Logic Input page of Conference ComposerTM. If the SWITCH OUT wire is connected to Logic Input pin 1, then you need to assign Pin 1 by left-clicking the desired pin in the DB-25 graphic and selecting the pink color (The pink color means that the pin is not grouped to other pins).
