THIS IS AN OLD STOCK ITEM - IT HAS BEEN TESTED AND IS IN FULL WORKING ORDER
A three-channel gate-to-trigger module (aka a pulse shortener) - very handy if you need a short, or very short, pulse to trigger an envelope generator, sample-and-hold module or just about anything else that prefers to receive a trigger rather than a gate. I've had these modules kicking around for a while, and whilst they're perfectly good at what they do I have a slightly better design which may eventually see the light of day.
All three inputs are normalled together, so it's quite possible to feed the same trigger to three different destinations but plugging something into an input will override the normalling. The pulse duration is controlled by the pots on the front panel, whilst the trimmers on the rear of the board determine the minimum pulse duration. These are set to sensible (for me) values by default, but feel free to fiddle with them if you don't like the settings as they are.
Gate inputs should be at least 3.5V, and the output pulse will be 5V - you can alter this by changing the voltage regulator on board, but since the core functionality is provided by a CMOS IC (a 40106) increasing the output voltage will also increase the required trigger voltage.
The module is 6HP wide and has a panel laser-cut from 3mm acrylic. A power cable and mounting hardware are also supplied.
