HI, Can omeone explain how come there are only two connections when there should be three? am I missing something? Regards, Lawrence

Hi,
I'm not sure which connections you are referring to - the 3 pins of the XLR? I have omitted the actual pad and piezo trigger, since it works just like any pad. The pinout is in another thread, can't remember which right now.

Krillo, The pads and peizo are OK.. I am not reeferring to them. From the XLR are there two connections or three? Typically there should be "Input" - "GND" - "Ouptut" if there is a Hall effect sensor or a pot for that matter. Input & GND would give 5 V and then Output and GND would give variable voltage based on the position of the magnet with respect to the HES. Correct me if my understanding is wrong... Regards, Lawrence

From the XLR are there two connections or three? There are two wires going to the PCB, no more is needed. The 5V that is supplied to the PCB via a resistor inside ddrum4 is pulled towards GND by the circuit, by proximity of the clutch magnet, thus creating a voltage level analogous to the position of the same.

..... can anybody upload Original DDRUM4 Hi-hat clutch photos with details, I solve the problem for the clutch open-closing... but the foot playing funktion is ineffective probably,
I need clutch's pictures..
( ý solve the problem with a powerfull magnet. a Neodymium magnet; it's a grey magnet. it is more powerfull then black magnets...)

the hi-hat doesn't work with weak magnets.. or a weak magnetig area.. it's important. and I work the hihat with the sound numbers 14,68,69, most sounds work with the hi-hat clutch.

Is there something in particular that you're looking to see in a picture of the clutch ? sam(otacon28)

thank you Sam, I am wondering to see the Clutch's details, specially under side of it. so maybe I understand the composite of the magnet and the Cover material. or the dimensions of the Magnet. maybe I can Build it. So thank you then ,, for your interest,

Just sent some pictures over to your email address you have listed on your membership account here . I can add some to this post also , but I figured you could see the pictures full size through an email .

. finally ý solved the dilemma, the confusion : )
yes the answer is re calibrating the module. but with this way.. with my idiot modul;
1- I removed the fabric felt on the midle of the hi-hat cymbal pad(removing felt in the hole) 2- then ý put the magnetic clutch on the hi-hat cymbal pad 3- Let the hi-hat clutch fall down on the hi-hat controller by its own weight 4- Press the System button until you get to the Trig Input mode for channel 10 . Select "HHT" with the Rotary Dial 5- Without touching the hi-hat stand , hold Shift and press Exit . The Display will briefly show "CAL" and the calibration is completed 6- then I remove the clutch and replace the felt to the hi-hat( to the hole) 7- then put in place the clutch again. 8- and then Secure the hi-hat clutch at a comfortable height for playing Thats it.
now the foot funktion(foot pedal count) and open-close hihat funktions are working verywell like..

Hi,
I've read this thread as I was looking for some information regarding a problem that has suddenly appeared on my Ddrum 4 SE hi hat (I've owned this drum set for years without ever having any problem).
The hi hat functions normally when the clutch is open, but when I press the pedal to create a closing sound, I now obtain confused reactions when the clutch gets in contact with the pad : a short crazy sequence (or even rattle) of opening and closing hi hat sounds heard in a random manner.
When I loosen the clutch from the metal rod of the pedal, and let it stay down on the pad with its own weight only, the sounds seem to be ok if I play on the hi hat pad with sticks (short lasting closed hi hat sounds). But sometimes the captor stays in "open" mode (even though the cltuch remains in contact whith the pad) and thus long lasting open hi hat sounds are triggered at every hit of a stick.
Apparently the cable is ok, and I have recalibrated the hi hat several times without any change.
I'am not certain I have understood all that is dicussed in this thread (English is not my mother tongue, and this thread is quite technical for me), and I hope my description of the problem is clear.
I would really appreciate it if anyone could help me.
Sincerely.

Hi lucsnarewalker, It sounds like something is broken or loose inside your hihat. Maybe soldering of XLR or component on the PCB inside the hihat pad. Try using another pad for the hihat input to rule out any fault with the hihat input of the module.

Thank you for your quick reply ! I don't have any extra hi hat pad, but I've tried connecting both a cymbal pad (set on CYB for the trigger input) and a tom pad (set on MH1) in the hi hat jack input of the DD4 module. It works fine (but they both use mono jacks). I'am not very familiar with electronics, but it seems that the solderings of the male XLR of the pad, the female XLR of the cable as well as its male stereo jack are ok. Here are photos of both sides of the PCB, in case you can see something wrong (+ pad XLR). Should I open the DD4 module to check the solderings of the hi hat jack female input ? Also, is there a way to be certain that the XLR / jack cable is ok ? Thanks again.
