DM10 module powered by battery.
« on: July 18, 2023, 12:10:47 PM »
My band are playing an open air gig in a very remote spot here in Scotland. Completely off grid. We're using Roland Cube battery powered amps. I'll be using my drums powered from the 12 volt batteries of my van through a 230volt inverter. The drum amp works fine (tested with a keyboard), but, when I plug in my DM10 module it powers OK but the volume output is very low and there's a huge amount of background hiss.
I'm figuring it's to do with a DC current being converted to AC (van batteries to inverter ) then being converted again by the DM10 power brick.
I'm wondering if the DM10 module could be powered by 9 volt battery so that its avoiding possible interference from other power sources.
It's a MK1 module.
Any ideas? Has anyone ever used their e-drums off grid?

Welcome to the Forum !

I have known some to use 12volt to 110 ac..no problems..but not 12 volt to 230 volt..then to 110 AC..not many in the US have to deal with 230 Volt.
The DM10 is 9 Volt AC..1.5amp..so I don't know how a 9 volt battery which is DC..would work..
The symptoms you posted sound like the DM10 isn't getting enough amperage, similar to those that used the wrong power supply with correct voltage but wrong amperage (too low) which caused odd behavior with the module.

Those is the power supply I'm using at home for the DM10
I'm not sure if it's the original supplied by Alesis.
It works fine at home and has done for many years.
Can anyone confirm if its original?
If its not the original maybe changing the power supply could solve my issue.

I don't believe Alesis ever offered a Factory 230-240 power supply for the module in the US.

Factory US Model is 110 9VAC..1.5 AMP in the US..

Instrumental Parts still offers the power supplies listed under the Alesis Brand....mostly they were Numark ( NUMARK was the Parent Company.. at the start of the DM10..then acquired by InMusic).Numark gear had a lot of interchangeability for power supplies..
The original DM10 "Charcoal" Module came with 1.3Amp...about a year later the Silver Module came out and the power supply for it was now 1.5Amp.
There is never any mention why...so one presumes it was under-powered for it's  features.
 
If the one you have worked at home had no issues I would check everything else.the Universal Power supply you show is 50HZ so it's a Pure Sine Wav.
I was mainly looking at how many amps were being supplied to it from the 230 stepdown after the 12 Volt.
Are there multiple pieces of gear connected to the inverter?..have you tried just the module alone connected?
I don't know if the inverter can be switched to 110..then get a 110 9VAC power supply and eliminate one piece in the power chain will guarantee any difference.

I don't know many doing multiple conversions on one piece of equipment (12 volt DC > Inverter> 230 Volt AC >..Stepdown> 110AC.) and it's affects  using multiple pieces of gear..The only time I knew anyone using 12v to 230v was for using Marshall Stacks from UK that were original wiring....that was many years ago.. most full bands etc use generators..I have known a few to carry around portable 12 volt Jump Starter/Jump Boxes that have 110 inverters built in and outlets..USB ports etc.
You may have better success checking in local European Performing Musician Forums.
I am sure someone has used the original DM10 over the past 10 years or the same power/chain/supply setup in an outdoor venue etc..

Thanks for the reply again. It's really helpful.
The inverter I'm using to convert 12v DC to 230v AC ( UK uses 230v for domestic electricity supply ) isn't pure sine wave. It's modified sine wave. A bit of research has shown that a lot of things need pure sine wave to function properly. I'm thinking this might be where my problem lies. I'll try and get a pure sine wave inverter and test this theory out.
I also might try a portable power unit such as the type that are used by campers etc Jackery, Ecoflow and many others have these, they have pure sine wave AC outlets and are lithium-ion so small and light. Does any one have any opinions on those type of portable power units?
Does anyone know how much electrical power the DM10 draws? I wouldn't have thought it would be a lot. This would help me get the right sized power unit.

Power demand of the DM10 X time it needs to be powered = the amount of power from the source required. Any one got any info on this?

You could check these calculators..enter in the info from all the devices/gear you use and get a by the hour rate..by the day..etc etc.
Most everything power related is based on WATTS.
