S HURE ® MX392 B ASICS The Shure MX392 is a surface-mount, electret microphone that includes a programmable membrane on/off switch that can be controlled externally via logic input / output terminals.
Switch Behavior User Action Required / LED Behavior DIP Switch Settings Push to Mute, Release to Talk (As Shipped) Press and hold switch to temporarily mute microphone; release switch to unmute.
Here is a drawing showing the functionality that is assigned to each DIP Switch: 5.
L OGIC P ORT The Logic Input port is a female DB-25 connector where pins 1-24 can be programmed to execute commands via the Logic Input page. Pin 25 is the ground pin and it can sink up to 500 mA of current. The Logic Output port is a female DB-25 connector where pins 1-20 can be programmed.
P HYSICAL C ONNECTIONS AND G ROUNDING In order to connect the microphone to the Vortex Device, first connect the audio portion of the microphone to the Vortex Device: Connect the Positi ve conductor (Red) to the Positive terminal, the Negative conductor (Black) to the Negative ter minal, and the Ground wire (gray) to the Ground terminal.
T OGGLE O PERATION (P USH TO T ALK ) 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.
Now, right click in the A CTIVATED C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O FF . Now, whenever the switch goes Active Low (0V DC), the Vortex Device will unmute Input 1. Now, right click in the D EACTIVATED C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O N .
Make sure that the physical wiring works by pressing the membrane switch. You should see the LED above the pin assignment lit in green: Repeat the above process for each MX392 microphone that you want to connect to the Vortex Device. L OGIC O UTPUT Go to the Logic Output page of Conference Com poser.
Next, right click in the A CTIVATED C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O FF . Now, whenever the microphone is unmuted (Mute = False), the LED will illuminate on the MX392. Next, right click in the D EACTIVATED C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O N .
Make sure the LED works as designed. If you press the membrane switch, you should see the LED above the pin illuminate in Conference Composer as well as on the MX392.
T OGGLE O PERATION (P USH TO M UTE ) Let's say that you want MX392 to be unmuted by default. If someone pushes the membrane switch, you want the microphone to stay muted until the user presses the switch to unmute the microphone. You also want the LED to illuminate when the microphone is unmuted and not illuminate when the microphone is muted.
Now, right click in the A CTIVATED C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O N . Now, whenever the switch goes Active Low (0V DC), the Vortex Device will mute Input 1. Now, right click in the D EACTIVATED C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O FF .
Repeat the above process for each MX392 microphone that you want to connect to the Vortex Device. L OGIC O UTPUT Go to the Logic Output page of Conference Com poser. If the LED IN wire is connected to Logic Output pin 1, then you need to assign Pin 1 by left-c licking the desired pin in the DB-25 graphic.
Next, right click in the D EACTIVATED C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O N . Now, whenever the microphone is muted (Mute = True), the LED will not illuminate on the MX392. Here is what the screen should look like when you are finished: Make sure the LED works as designed.
When the membrane switch is pushed again, the EF Device toggles the state from unmuted to muted. Now, the LED should not be illuminated since the input from the MX392 is now muted.
M ACROS Go to the M ACROS page of Conference Composer. To make things easy, label Macro 0 as MUTE ON and label Macro 1 as MUTE OFF. Then, for each microphone that is physically connected to the Vortex, add commands to Macro 0 that mute the microphones and add commands to Macro 1 that unmute the microphones.
In order for one microphone to mute all microphones, we need to be able to mute and unmute the microphones on all units regardless of whether a microphone is muted from the Vortex EF2280 or the EF2241. To accomplish this, we will use the BROADA command to send MUTEI commands from one unit to the other unit.
Repeat that same process for Inputs 2-4 of the Vortex EF2241. The, perform the same procedure to unmute Inputs 1-4 on the Vortex EF2241. Remember that there is a colon after the BROADA command.
Follow the same procedure for muting the Inputs 1-8 on the Vortex EF2280 from the EF2241. Here is what the Macros page for the Vortex EF2241 should look like when you are finished: L OGIC I NPUT Go to the Logic Input page of Conference Composer.
Now, place the cursor in the A CTIVATED C OMMAND column for Logic Input 1 and select I NSERT , M ACRO , 0 ("MUTE ON"). Now, whenever the switch goes Active Low (0V DC), the Vortex Device will execute Macro 0. Now, right click in the D EACTIVATED C OMMAND column for Logic Input 1 and select I NSERT , M ACRO , 1 "(MUTE OFF").
Repeat the process for each microphone that is connected to the Logic Input port. If you are successful, you should see this on the screen (the screenshot is from a Vortex EF2241): Make sure that the physical wiring works by pressing the membrane switch.
Next, right click in the A CTIVATED C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O FF . Now, whenever the microphone is unmuted (Mute = False), the LED will illuminate on the MX392. Next, right click in the D EACTIVATED C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O N .
Make sure the LED works as designed. If you press the membrane switch, you should see the LED above the pins illuminate in Conference Composer as well as on every MX392.
L OGIC I NPUT Go to the Logic Input page of Conference Composer. 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).
Now, right click in the H ELD C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O FF . Now, whenever the switch goes Active Low (0V DC), the Vortex Device will unmute Input 1. If you are successful, you should see this on the screen: Make sure that the physical wiring works by pressing and holding the membrane switch.
L OGIC O UTPUT Go to the Logic Output page of Conference Com poser. If the LED IN wire is connected to Logic Output pin 1, then you need to assign Pin 1 by left-c licking the desired pin in the DB-25 graphic. The pin will turn color from gray to pink.
Next, right click in the D EACTIVATED C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O N . Now, whenever the microphone is muted (Mute = True), the LED will not illuminate on the MX392. Here is what the screen should look like when you are finished: Make sure the LED works as designed.
When the membrane switch is pushed again, the EF Device toggles the state from unmuted to muted. Now, the LED should not be illuminated since the input from the MX392 is now muted.
L OGIC I NPUT Go to the Logic Input page of Conference Composer. 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).
Now, right click in the H ELD C OMMAND column for Logic Input 1 and select I NSERT , I NPUT , 1, M UTE , O N . Now, as long as the switch is Active Low (0V DC), the Vortex Device will mute Input 1. If you are successful, you should see this on the screen: Make sure that the physical wiring works by pressing and holding the membrane switch.
L OGIC O UTPUT Go to the Logic Output page of Conference Com poser. If the LED IN wire is connected to Logic Output pin 1, then you need to assign Pin 1 by left-c licking the desired pin in the DB-25 graphic. The pin will turn color from gray to pink.
