The Multi-Trigger 3 (MT3) is an upgrade from the Multi-Trigger 2. Improvements include greater ease of use, an additional 4 outputs on the lid of the box for camera and flash, elimination of the focus/review switches for the camera shutter, pulse outputs for diagnostic purposes, and a one-sheet label designed specifically for the MT3. The MT3 has all the same functions as the previous model. These include:

  • all components hard-wired for durability
  • operates either on a 9V battery or an optional 120-240 VAC to 9 VDC adapter
  • LEDs to indicate power on, photogate alignment, and event triggering
  • test button to produce output pulses without a sensor cable connected
  • inputs for microphone and photogate sensors as well as external triggers
  • selector for microphone or photogate input
  • fine (up to 0.05 s) and coarse (up to 0.5 s) delay adjustments
  • selector for one of two delay ranges (0 to 0.5 s or 0 to 0.05 s)
  • continously-variable timeout setting up to 1 s
  • instant and delayed optically-isolated outputs

The MT3 kit includes all the parts for the (i) control box, (ii) the microphone cable, and (iii) one of the two types of photogate cable. The MT3i version of the kit includes parts for the interrupter-type photogate. This is version you would choose if you were, for example, using the MT3 in conjunction with the AstroSplash Drop Controller to capture drop collisions. If, on the other hand, you need a photogate cable with variable width for larger objects, you would select the MT3v version.

 

If you want both types of photogate cable, you can order the second type from the MT3 accessories page. Also see the accessories page to order the optional 9V AC/DC adapter.

 

The Multi-Trigger 3 kit with control box and sensor cables requires assembly. Experience in wiring, soldering, and troubleshooting electrical circuits is assumed. Here are the assembly instructions.

What else is needed

  • A trigger cable is needed to connect a flash unit or wireless transceiver to the Multi-Trigger 3. Select a cable with a 3.5mm plug.
  • In order to trigger a camera shutter, you need a shutter cable.

Flash Trigger Cable Kits

These kits are for preparing a cable to connect the flash output of one of our trigger circuits to a PC jack. The cable kit with 3.5mm plug will work for the Multi-Trigger 3. The cable kit with RCA plug will work for the Sound Trigger 2.

 

The flash trigger cable kits include a PC-type connector for the flash, either a 3.5mm mono plug or RCA plug, 3-ft of 2-conductor cable, and heat-shrink tubing. Assembly is required.

 

Hot shoe adapterIf your flash unit doesn't have a PC jack but does have a hot shoe, the hot shoe adapter shown to the right can be used together with a flash trigger cable for flash triggering.

 

If your flash unit is one of the Vivitar models 283, 285HV, or 3700, you'll need a Vivitar PC-1 cord to connect to your flash unit. Click here for one possible source. If you're triggering your flash wirelessly or your flash unit has a 3.5mm synch jack, see this page for 3.5mm cables.

Select this cable kit for the Multi-Trigger 3. Select this cable kit for the Sound Trigger 2.

Shutter Cables

 

We provide shutter cables for most camera makes/models for use with our triggers. When you order a shutter cable, we include a 6-ft extension cable as well as an adapter to convert the cable for use with the 3.5mm stereo jack on our triggers.

 

Select your camera make/model below and note the corresponding ID. If you don't find your model listed, compare the socket on your camera to the photos below. The photos will enlarge by clicking on them. If you are still unable to determine the type of plug that you need, please contact us. If you already have a shutter release and want to convert it for use with our triggers, this page may help.

 

All shutter cables, which include extension cords and adapters, are $9.95.
