Re: eq break down
I posted a link to some images of the innards of my DCX over in my "DCX Woes" thread.

Re: eq break down
I see that David, thank you. I got them right here infront of me and thinking I might take them apart to see if it might be an easy fix.
Drumming is a way of life.

Re: eq break down
After reading your post, I see there is a very active after-marketing for hotrodding the DCX machine.
Why somebody is willing to spend up to $1400 modding this box escapes me, but it appears to have a very loyal following.
Evidently all the analog circuity in the DCX is marginal.
The power supply gets replaced, along with the clock. Evidently the new clock is a real jitter cure.
The output stages are gutted entirely and all the glue between the digital converters and output jack are replaced with a high quality (read: expensive) transformer. All this modding turns the DCX into a jitter free, and hiss free box.
Evidently they user a bunch of el-cheapo OpAmps in the output circuitry. These all get replaced.

My biggest worry is that when I'm dead and gone, my wife will sell my toys for what I said I paid for them.
Re: eq break down
I've seen that too. I think it's a bit beyond what David is trying to achieve, which is running the box reliably with default properties. There is a replacement power supply board and tranny available online, though it still is quite some soldering, and we're not sure if the problem actually stems from the power supply.

Re: eq break down
That's the Behringer way, the circuit design is fine but they cull their parts from the bottom of the barrel. The DSP chips are fine because there is no bottom of the barrel source for those, but I'm sure they use 4551 op-amps or the equivalent throughout because they get them for a dime, instead of paying a buck for a decent chip.bgavin wrote:After reading your post, I see there is a very active after-marketing for hotrodding the DCX machine.
