Hi and welcome!

How high have you set the volume forr the headphones? It can be grounding 
problems, a broken amplifier or simply different headphone standards used 
nowadays and back in the days...

Hi, & Welcome !

I have 2 SDS9 that have both the same problem ...
Therefore I'm not using that much so ...I just let it like this ...

Once, I had the same problem on my SDX, when we opened the console we've seen that a screw was going through the headphones lead ...

I'm not sure it does help you, but you know a bit more about it ...
I'm tempted to say that it might be often on a Simmons ... from my own experience...

bye & good luck !
Patrice.

  Hi, I am new in this group so hello to everyone :)

  I recently bought a black sds9 5 piece set in a simmons rack, sds9
  module and manual in english :)

  I am very satisfied with it, but have one little "problem". I get some
  background noise (static?) from the Headphone output. What could cause
  this? 

  Thanx

I think the Simmons were designed for a 50 ohm headphone. Using a different impedance load could cause you to hear more of the noise floor. Or the cable from the headphone jack to the PCB could be pinched between the bottom and top part of the chassis.

Yes, impedance was the word I was looking for... :)

Re: [Simmons Drums] Noise from Headphones

2007-01-09 by michael.buchner@debitel.net

The headphone amp of the SDS9 is located unfortunately on the power-supply-board and not on the main pcb. Rumours say, that they didn't want to build a headphone amp into the unit at all because they never had headphone amps in their brains: The main pcb's design was finished, but marketing factors forced simmons to add the amp, so this was the only way.
The amp is fed from the mix out by a shielded wire, but the connection acts like an antenna for all noise, buzz and hum. But if you run the mix out to a mixing console, you can use the console's phoneamp. If you don't need the SDS9's mix out, you can plug an external headphone amp there. So: Simply ignore SDS9s headphone jack.
Greetings
Michael

Must be just rumours. I believe the sds8 had a headphone jack and came
out much before the sds9. The headphone amp being on the PS shouldn't
matter as the cables running to and from it. Repositioning these 
cables may limit the interference. But I would first try the 50 ohm
headphone.

Hi!

I guess that they wanted stuff you'd gig with, not practice with at home. 
The SDS-2 has a separate headphones amplifier which is from another planet 
or something. With a pair of modern headphones plugged in you can call your 
ear doctor on the double 'cause that thing is mental and dangerous.

electronically yours, jesper - tried it once - *aouch*
