I purchased a used dm10 kit for my son and trying to get it setup. Everything works except crash 1 and 2. The cables for each only have one connection which i plug into the A slot of the cymbal. Turn on note chase and it doesn't pick up anything. Cables seem good - i can plug the crash 1 into a rack tom and i hear a cymbal crash when i hit the drum. The cymbal is also ok as i can plug in both cables from the ride cymbal and it works fine.
I don't know what to do next to get them working.
If it is a factory/stock kit..meaning Alesis DMPad cymbals and not a kit pieced together.
There are (3) 12" cymbals...all are single cable...one is hi hat (single zone).. (2) crash cymbals,..one has a choke (dual zone) , one does not (single zone).
They should be labeled underneath.
If you have the factory color coded harness..
Crash 1 (with Choke) is TRS cable (Red)..input 7 (Crash 1)..
Crash 2 is TS cable (Blue) input 11 (Perc 3)
If cables or cymbals are mixed up (inputs 7 and 11) the module will show a calibration error on power up.
If you can't identify which cymbal is with choke..make sure the correct cables are in the correct inputs..power off.. connect cymbals..power back on.
If you get a calibration error..power off.. swap the cymbals...power on
The module calibrates each time it is turned off and on.
I don't know what you mean by "Slot A" unless it's a 2 cable cymbal which is specifically for the Ride Cymbal and cymbals with 2 jacks won't work with just one cable unless a dummy plug is in one of output jacks.
After you are sure cymbals/cables are correct...check all the levels etc
With Note Chase on ..
Check MIX BANK (Faders)..press to change A-B
"B" must be lit to use Fader for Crash 2 (Perc 3) level..
"A" must be lit to use Fader Crash 1 (Crash) level..
Press EXT TRIG..IN (F1)increase SENSITIVITY
Under EDIT
Press INST....F2 (LVL) >increase LEVEL.
If you press INST while in level (LVL) it will switch Layers A-B..B-A
