Active DI Box Location
I've just ordered an ART Dual X Active DI Box and was thinking of putting it on top of my amp, is there a potential problem in doing this as I have read somewhere that you can get a hum if you do this due to it being so close to the amp?
I would prefer to put it on my amp if possible due to all the wires coming out of it rather than it being on the floor. I haven't received it yet so I can't tell whether it will create a problem or not, but obviously where it ends up going will decide on what length connecting cables to get for it.
Well I used the ART DI Box last night for the first time, set it all up on top of my amp and everything worked ok until the sound check and my bass channel was putting a radio station through the PA!
We didn't have much time before the show started so we quickly replaced my (Digital) wireless for a standard cable and all was fine. I don't know why the wireless unit was causing the interference, I could sort of understand if it was an Analogue wireless system but mine is digital and works on 2.4ghz? I have never experienced any problems before with the wireless in the 3 years I've been using it.
Had we more time I would have tried a different channel to see if that resolved the issue, but we have another show this Saturday and won't have the opportunity to try and identify the problem before then. Has anyone experienced a similar problem? Our sound guy suggested it could be a lead acting as an antenna and picking up the radio signal. Could it be something as simple as a lead? I will be using the same leads at the next gig, so hopefully it was just a local issue, but will try setting the wireless to a different channel beforehand anyway.
This also leads me on to my original posting, i.e. was the problem caused by putting the Active DI Box on top of the amp?
Any suggestions or ideas would be welcome. :hmm:
At the gig last night I set the DI Box on the floor, used the same Wireless channel as before and didn't experience any problems whatsoever.
Perhaps there was some interaction between the wireless unit and the amp circuitry when The DI Box was on top of the amp? Don't know really, it may have just been a one-off situation.
don't think that just because its "digital" that it is not subject to operational laws as UHF in respect to frequncies...if someone told you different when you purchased this then they did you a severe disservice.
in fact i have come across this many times and in many places. there is actually sooo much more things running on the 2.4 band that in certain places its almost full...think about it, you have wireless routers, Bluetooth, just think about every mobile phone...
in theory, for example for all you know is that someone could of been listening to the radio on their phone and their phone happened to be transmitting it somewhere on a the same exact part of the 2.4 pie...
which wireless unit have you got???
i also agree that i doubt that it is the DI box...but stranger things have happened...and to be honest...i highly doubt that it is the cable...this is pretty rare that this would present a problem, also it certainly isn't unheard of. but i doubt that its the cable...
