Power conditioner rack help!!!

[akastaten]

Hi all,

 

first of all class forum! Been noseying around and I'm well impressed. Secondly, I need some advice. I'm building a rack for when I gig. This is what I idealy want at the top a power conditioner. Not only to I want my gear protected but also I'm very fussy about exterior sound. What I mean by this is mainly hums from venues mains. I was playing in a church and I was stage left. My the engineer switched my monitor on it was humming. I didn't really mind this however I plugged into the designated sound sockets and my Mesa boogie combo was also humming. Now this bothers me. So here's my questions... Do rack power conditioners stop this hum? If so do they all do it? A behringer pl2000 is £40 an eta pl8 is 50 a t-racks is about 60 a furman rack is about 300-500... All I'm looking for is enough power distro to power tc electronics fx unit, an Ada mp1 preamp, a korg dtr1000 tuner, maybe a graphic eq and to make sure no hum at my Mesa boogie express combo. Will they do the job? Do I really need to spend 500 odd quid for what I'm looking for? Any other suggestions? Samson powerbrite pb10 pro? Ideally I'd like a light to illuminate rest of rack

 

thanks in advance. Hope this makes sense

 

oh lastly... What's the cleanest graphic eq with around 15-32 bands I could put into my rack that wouldn't suck tone out of my guitar?

Power conditioners aren't a magic bullet which will fix all noises on a mains system , they should have some means of electronically lifting the earth to reduce or get rid of the hum on your kit check the manuals of the piece your after, most will supply enough juice for your rig.

 

With regards to your tone, if you send the signal from the guitar into the ADA. into the TC, then into a graphic, then into the boogie what chance does it have ? Both the ADA and the amp have more than adequate tone controls so the graphic would be superfluous. On a personal note, I have never been a fan of using a seperate pre amp with its own colour then sending it into a guitar amp which again will have its own colour. A boogie sounds like a boogie, a marshall sounds like a marshall, the ADA sounds like an ADA, to use it to its full effect put a power amp in your rack buy a four by twelve and leave the boogie at home.

I bought several T-Racks with the built in light and power conditioner. Complete pile of SH1te. Whoever designed it used the wrong value of Cs across the Live and Earth and Neutral and Earth causing 7mA of earth leakage. 4 of them switched on together caused RCDs to trip frequently.

 

There is nothing in a power conditioner to block hum, just HF noise.

 

What is required is either complete isolation from the mains supply via an isolation transformer then use a DI box with the earth lift switch OFF, IE earth present to provide you with 1 earth

 

or

 

Using the supply directly with earth and being a guitar cabinet, micing it using a 57, 906 or whatever.

 

Hum is a direct result in having multiple earth paths or no earth at all.

 

 

Hope that helps Dave.

Cant recommend these any higher. We have three of these, so all the PA is filtered. They are reliable, rugged, the lights are good in them (both front and back). There is a single switch on it so you can power down the whole rack. I reccomend getting an IEC socket to 13Amp 4Way, and mounting that underneath, so any Wall-Warts (transformers) can go into that. It vastly reduced the hum in our rig, and the resettable breaker is handy. It has a display for Voltage and Amp Draw, which again is handy if you are pulling a lot through the amp.

 

If you have any questions about the unit, drop me a PM and ill try and help out

some nice features on that, but I wouldn't pay £110 for it!
