2011-2012 Holiday Shop Closing

Thanks to all of our new friends and customers for making 2011 a really big year for us at Disaster Area Amps.  We couldn’t have done it without you!

Disaster Area Amps will be closed from Monday 26 December until Tuesday 3 January.  The Store will remain open, but email support will be limited.  If you ordered before 15 December, we’ll do our best to ship your pedal before the end of the year.  If you ordered after the 15th or if you have custom firmware or other special options, your order will probably ship the first week in January.  Orders placed during our shutdown will likely ship the 2nd week in January.

In 2012, we’ll be offering a few new products including the DMC-3XL.  Stay tuned.

Thanks!

DMC Series Power Over MIDI

Some MIDI devices can get “phantom power” from the MIDI out of the previous device in line.  One pin of the MIDI out is at 5VDC, current-limited with a 220 ohm resistor, and the other active pin is connected to ground by the microcontroller or microprocessor in the device.  Although it’s not technically part of the specification, it is possible to steal some current from that 5V pin.  In order to do that, we need to make ground available to the device that’s stealing power.

On the DMC-3’s, the MIDI jack has pin 1 grounded by design.  On pedals with a PCB-mounted jack (DMC-2, -4, -6,) the ground may or may not be connected to pin 1.  The first thing to do is plug your other device into the DMC MIDI out and see if it works.  If not, here’s how to fix it: Continue reading

DMC Series Wiring Diagrams Added

A lot of folks have bought DMC PCBs lately, and the existing wiring diagram is a little too general to be helpful.  I’ve added a new drawing that shows the DMC-2, DMC-3, and DMC-4 wiring, plus the internal box layout for the DMC-3.  There is only one way to get all the parts for a DMC-3 in a 1590B sized box, believe me!
