dehaas battery block
« on: July 13, 2006, 09:39:42 AM »

Hi, I noticed that  my dm pro has a power converter that steps the power down to 9 volts, I was wondering if the dehaas battery block that powers the zendrum  will run the dmpro?
thanks

The battery block passes power through a MIDI cord.  The DMPro power jack is not MIDI, the pins are in different places.

Hello everyone I had an idea or two about alternative power for the ZENDRUM as well, that  I spoke with  Chris about. He reccomends NOT to modify anything just use the block or get the battery mod from the Zendrum folks.  By the way, the Alesis DM Pro and most of their gear from that time period run on 9 volts AC as where the Zendrum runs on 9 volts DC.  Just my $.02.  See ya, Mark

Hello All,

It's Chris deHaas, regarding the questions about powering the DM Pro from the battery box - it will not work, the DM PRO draws way too much current to run off of a 9V battery - it is true that a lot of Alesis equipment does run off of a 9V AC wall adapter, not 9V DC.    Plus, the battery box was designed to power only the Zendrum and nothing else.   

After fixing several Zendrum motherboards that were damaged because someone was trying to modify them to run off of other sources of power, I now strongly suggest to everyone to only use the Merge box, Merge Brick or Battery Box and nothing else to power the Zendrum. 

thanks,

Chris
