Any thoughts or advice would be appreciated, as I am about to return or exchange my IP2000.
We do 'Dueling Pianos' professionally - so, two keyboards, and two mics. That's it. Simple set up, way less than other posters here running full bands through IP2000.
I am using a Mackie ProFx12 V2, which has been tested with other speaker setup's and sounds great with those....
But with Turbosound, hear me out:
-Was getting terrible crackling and distortion. Went back and forth with Music group. Identified the likely cause, namely, that the XLR line out from Mackie was too hot, and clipping the input gain's on the IP2000. And according to the spec sheets, this was true - IP2000 can handle up to +22dB from a mixer or other line level source.
So I did two things: A) tried the 1/4 inch Main out from Mackie, which is rated at +22dB. Same issues. And then B) I used a freaking DI box from the Mackie, into the Turbosound, cutting th impedance way down - same issues!!!!!
Ready to ponder? Check this: bluetooth streaming sounds amazing, no clipping, through my IP2000 and I can jack the volume to unfathomable levels with no problems. Likewise, I can use a guitar and keyboard directly into the inputs, and raise the volume way up, again, no clipping. But as soon as I use more than (2) instruments, through the mixer, I get static and clipping even at low volumes!!!!!!!!
Please advise and thank you! Do I just have a bad unit?
I feel really bad for sending back a perfectly good Turbosound. Everyone seemed certain it wasn't the mixer, I would guess because good quality ones don't malfunction very often.
I'm thinking you may have the ip2000 input gain set to be too hot. Lower the input gain on the ip2000 channels and make that adjustment up in volume by raising the master output of the ip2000.
Were you able to figure out why yours was crackling?
Last night the IP2000 started terrible crackling whenever the second mic was operational. I replaced all cables and used different mics but still the same. Just the line in sounds fine. Only when the mics are used the crackling sound comes.
Looking forward for guidance from this group to help troubleshoot.
Has anyone whose IP2000 is out of warranty opened the unit to look inside? I recently saw a picture of a unit that had been opened and was surprised (as was the owner) to see that the subwoofer has a passive crossover network. I have been unable to find any meaningful specs relating to the crossovers in this system, so it makes me wonder if the HF tweeter is treated in the same way.
If it is a case of the HF driver being passively crossed over, then I feel this could explain the distortion being heard by some. On this and other forums, the distortion heard is often related to when a microphone is being used, and, ok when program music is played. This leads me to conjecture that if a low slope passive crossover is used on the HF tweeter, any microphone plosives will be below the filter cutoff and tweeter operating point, and will get through to the tweeter causing the distortion. On program music there are no such transients.
Now until we get a good look inside one of these units, this is just speculation. So if anyone is prepared to open theirs up and check it out, and maybe put up some pictures of the internals we'll just have to speculate.
It appears that this is not an isolated problem. There are plenty of reports on numerous fora that there is a problem with this model. I think it is time that TurboSound come out with a statement or a fix for this situation.
