Hi,

Can somebody explain what a rim-switch is?

Here is the answer to your question, and many other answers!
   Thanks to Jonathan Karow ... whether he knows it or not!
   Dual Zone/Stereo Pads and the Famous Input Question
   By Jonathan Karow 

   I am commonly asked many questions about stereo inputs on 
electronic drum modules in relation to dual zone or stereo pads. I 
hope that this information answers many of the questions that are 
simple but seem confusing to many. Hope this helps...Scott

   Stereo Pads (Membrane Switch/Piezo)
   Stereo pads and dual zone pads do have their differences. A stereo 
pad uses two different types of  technology to assure two separate 
zones and allow choking capabilities to the rim section. The rim
zone is commonly a membrane switch (like an on/off switch) that can be 
choked with many common modules such as the Roland TD series and 
Yamaha DTX. The center section of a stereo pad uses the industry 
standard piezo transducer technology. Most common stereo pads are of 
the round rubber type with a raised rim section. In some cases, such 
as the Roland stereo pads, the head and rim have to be struck 
simultaneously in order for the rim switch to be activated. Most 
drummers tend to prefer stereo pads as cymbal triggers rather than 
drum pads. 

   Dual Zone Pads (Piezo/Piezo)
   A dual zone pad such as the Pintech CC102 ConcertCast, Ddrum Cast 
Precision or the Roland V-Drum pads are intended to be used for 
convincingly real rim shot and cross stick patterns. This is 
accomplished by hitting both the rim and head of thed rum 
simultaneously. Two totally separate sounds can be accomplished with a 
little tweaking of your module parameters. Dual zone pads are
   commonly more drum like professional pads that use real drum heads 
(Pintech, Ddrum) or mesh   heads (Roland) and consist of two piezo 
transducers (one for the head and one for the rim). 

   Module Inputs for Stereo and Dual Zone Pads
   It is important to understand that there are 3 types of inputs on 
modules - mono, stereo, and dual. 

   Basic Alesis modules (D4 and DM5) are designed with mono inputs. 
Dual zone pads (Pintech CC102 ConcertCast, Ddrum Cast Precision or the 
Roland V-Drum, etc.) can be used with the   Alesis modules. Pads like 
the Pintech ConcertCast can utilize both rim and head sounds with the 
use
   of 2 standard mono cables connected into two separate inputs. The 
Roland V-Drum pad and Ddrum   Cast Precision pads require special "Y" 
adapters and 2 cables to accomplish dual zone capabilities
   with the Alesis D4 and DM-5 modules, but this can be done never the 
less. 

   The Roland TD-10 V-Drum module consists of 1 dual zone input (#1) 
and 11 stereo inputs. The   Yamaha DTX consists of 2 dual zone inputs 
(#9/10 and #11/12) and 8 stereo inputs. A "Y" adapter
   is necessary to split up these inputs (dual Piezo inputs) when 
using pads that have mono Piezo   outputs. E.g., the Roland V-Drum pad 
has a single stereo jack that can be plugged directly into the
   dual zone input when using a stereo cable. The Pintech CC102 pad 
uses 2 mono outputs. It will   require a stereo "Y" adapter and a 
single stereo cable to utilize both zones on a dual zone input such
   as #1 on the Roland TD-10 or #9/10 and #11/12 on the Yamaha DTX 
module. Hosa manufacturers   a stereo "Y" adapter that can commonly be 
purchased for around $6.00 at music stores (Radio   Shack currently 
doesn't carry these adapters). Stereo inputs (membrane switch/Piezo) 
are intended   for stereo (round rubber chokeable) pads only! These 
types of inputs are found on the Roland TD5,   TD7 and TD10 with the 
exception of #1 input on the TD10 and the #9/10 and #11/12 on the
   Yamaha DTX. 

   Dual zone pads (dual Piezo) such as the Pintech CC102 ConcertCast, 
Ddrum Cast Precision or the   Roland V-Drum pads can utilize both 
zones on all drum modules the same as with the Alesis. This still 
requires the use of 2 inputs. Only 1 zone can be used on stereo pads 
(membrane switch/Piezo)   when plugged into a mono input such as the 
Alesis D4, DM-5, #1 input on the TD10 and the #9/10 and #11/12 on the 
Yamaha DTX.
