The Multi-Trigger 2 has the following features:

all components hard-wired for durability
on-off switch
operates on standard 9V battery
jack for optional 120-240 VAC to 9 VDC adapter
LEDs to indicate power on, photogate alignment, and event triggering
test button for the delay unit
inputs for microphone and both variable-width and interrupter photogate cables (parts for cable assemblies included)
switch to select for microphone or photogate input
sound trigger can be activated by a finger snap at a distance of 30 ft. or more
fine (up to 0.05 s) and coarse (up to 0.5 s) delay adjustments
switch to select one of two delay ranges (0 to 0.5 s or 0 to 0.05 s)
continously-variable timeout setting up to 1 s
sensitivity adjustments for the sound and photogate triggers
external input to connect other triggers to the delay unit
instant and delayed optically-isolated outputs for camera and flash

The PC board used by the Multi-Trigger 2 is shown to the right. Locations of components are labeled. Holes are numbered to aid in making connections to the lid of the control box.

The PC board is bolted to the lid of the project box. This reduces the possibility of breaking connections when the lid is removed to add or replace a battery.

Either of the MT2's two optically-isolated outputs can be used for camera or flash. These outputs cannot be used for older model high-voltage (>80 V) flash units. However there is an optional extender kit that provides outputs for high-voltage flash units. Click here for the extender kit.

The Multi-Trigger 2 kit requires assembly. Experience in wiring, soldering, and troubleshooting electrical circuits is assumed. Here are the assembly instructions. (The current build is Build 3.)

Accessories for the Multi-Trigger 2

120-240 VAC to 9VDC adapter

The AC/DC adapter provides a substitute for a 9V battery to power your HiViz circuits. The adapter accepts 100-240V input voltage at 50-60 Hz; output is a regulated 9 VDC. The power rating is 10 W.

PC Board for Multi-Trigger 2

You may purchase the PC board only. No other parts are included.

Notes:

This board is intended for use with the Multi-Trigger 2 enclosure or a similar enclosure of your design. The PC board is not intended to be used for a stand-alone trigger circuit, as it doesn't include holes for PCB-mount potentiometers, jacks, switches, and LEDs.
The version of the board that we're currently providing is for build 3 of the MT2 kit. The numbering of holes for the jumper wires is different between builds 2 and 3. Here is the conversion table.
