dbx Drive rack 360 Venue
« on: May 07, 2019, 09:59:08 pm »

Hey all,

I'm super curious to know if this little drive rack could do a decent job at tuning a PA? What kind of results do you think you could get from a product that advertises 'wizard' to measure a room response and auto correct it? I know this question sounds ridiculous being posted in a professional sound measurement forum but I'm curious to know if this is a gimmick or maybe has some value as a quick tool to measure and correct room/PA responses?

For those who may not know about the DBX venue360, the unit has a RTA mic input and asks you to place that mic in various places around the speaker system. A sine wave sweep is played from the unit and measured. The resulting measurements are averaged and inverted through auto EQ correction. You're then able to tweak the settings a bit and even pull from a library of speaker/amp manufacturers.

Are SMAART guys/gals out of a job or are they safe? J/K :P    I AM NOT WITH DBX

I think we are all safe.  Half the problem with the taking of measurements is making sure the ones we take are useful and knowing what to do with the measurements.

Yeah, I don't think the unit would be able to differentiate a comb filter from any other dip and adjust accordingly. Maybe there's little use in the DBX but I'm not sure about PA Tuning.

I'm told the Otto Eque function is better than it used to be (I'd hope so).  It's still time-blind but apparently does the averaging better (secret sauce).

There are ways to make use of this tool if one is aware of its limitations and accordingly makes *valid* measurements, but it is not a replacement for a dual channel FFT analyzer and knowledgeable operator.

The VENU360 does OK at tuning, but... it introduces eight (8) EQ adjustments any time you run it. A lot of the changes overlap one another, which could cause some phase issues. EQ introduces phase shift, so the more you EQ, the more shift there can be.

Sound-wise, it lends itself to the brighter end, so we always used the "reflective room" setting, which tames down the high frequencies a bit.

I have used the AutoEQ in the VENU360 to tune our JTR rig (3TX over Orbit Shifters), as well as Smaart V8 and TEF. I've also worked with Jeff from JTR to tune our rig and we A/B'd the results from the VENU360 and Jeff's TEF equipment - both were pretty similar with their end result.

dbx seems to have done a decent job with the VENU360 AutoEQ. Is it perfect? Nope, but neither is Smaart or any other tool.

agreed that the human element is what makes the largest difference but interesting to know that it's semi decent at tuning a PA, maybe I'll give it a whirl and just listen for myself.

What do you mean by "tuning a PA"?  This phrase gets used a lot but I'm not sure the same definitions are always used...

Kind of like "tuning the room."  Really?  We have an EQ for that:  the D9.

How many rackspaces will that take? I don't think I can spare that many...
