This is why I will never buy a DriveRack PA

After briefly reading over most of the content in this thread and in the referenced articles, I am left with but one burning question in the back of my mind...

Who in their right mind turns off an amplifier last?!

Amps should be the last thing turned on and the first thing turned off to avoid blowing your speakers on any number of components that pop when powering them on or off. All of my mixers do it, all of my EQs do it, all of my compressor / limiters do it, all of my active crossovers do it and so on and so on. Turning your amps on first or leaving them on until last is simply asking for trouble and is quite irresponsible.

For the record, I do not yet currently own a DRPA.

This issue is a whole lot of nothing. Follow proper procedure for power up and power down, then there is nothing to worry about.

In the event of a breaker trip you should always power down the effected pieces anyway. If you reset the breaker without doing that, you're just asking for another trip when the initial current rush happens on power up.

The main reason to get the 260 vs. the PA is here. :p

Yeah, I guess if you're a dummy and accidently turn off your processors all the time. In the mean time why don't you accidently turn off your power conditioner? or your mixer? or your cd player?

In the only plausible event that the DRPA would turn off without intent would be in the case of a power outage. However, if you have a well designed amp, such as the QSC PLX series, the amps will cut off any signal right when the power pulled - to prevent speaker damage.

I actually had that very situation happen to me almost a year ago, about three months after I bought my DRPA. The power spiked for about 15 seconds, and then went off for ten minutes at an event I was working.

When the power came back on, all of my stuff was fine....... except for the DRPA. It was dead, and the fuse was not blown.

I bypassed it in the rack, readjusted my mixer's eq settings, and kept going.

Other than that little blip, I have been happy with the unit, and it has gone through some paces!
 
All good points about the correct sequence for amps to be powered on and off but...accidents and power failures do happen :wink:

As I previously said...adding the BEHRINGER DEQ 2496 to the DCX 2496 will take you into the realm of the DR 260. They easily connect via a single cable. I'm not saying they're as good as the 260 but they're an alternative.

Many companies have been making DSPs for years, including DBX's cousin BSS, ASHLEY, YAMAHA and many more. The DR PA was geared more towards the MI/DJ market and is a great product...just be cearful to avoid the 'pop' issue and like much of our digital gear, it can be very sensitive to electricity issues like brown outs and surges. Just yesterday I spoke to a local DJ who had his DR PA board destroyed by a power surge which got past his protection :shock:

I know some of the DRPA owners are a bit touchy about hearing the news so I expected a few flames thrown my way. It is a bit like buying tires for your automobile because you were told they were puncture-proof and then you learn if you are driving them when it reaches a certain outside temperature the tires blow, causing a serious accident. They feel the need to defend the purchase and never drive at that temperature even though they do not know exactly what temperature the blow-out will happen.

The very box that is touted to protect your speakers (when properly administered) can be the source of the failure. The DR260 has a relay that opens when the mains power is lost and a delay during reapplication of power.

Of course we all will power down out electronics in the proper order when we have control over the situation. Doing anything else is ludacris. Fact: the DRPA will put out a spike everytime it is powered on or off. If some of my fellow posters to this board are absolutely sure of the future I think they should be in the insurance business. They will make a killing $$.

I believe the DR260 is not a fix for the DRPA. It is a higher capability model. The DRPA is a stereo-only unit. Whatever you do to one channel will be done to the other. In addition to all the DRPA can do the 260 can also be a dual-mono which is completely different from stereo. As an example, think mono (lo-mid thru hi freq) to one input feeding left and right stacks and aux fed sub freq to the second input feeding the subwoofers. This setup is almost useless for DJs but it does highlight the difference. I use mine just this way often.

I would say if they simply put a $3.00 relay across the outputs to control the spikes the DRPA would be the cat's meow. What would be wrong with a DRPA Mark II? DBX has stated they will not fix it in a future release of the unit. That leaves an opening for other manufacturers.

John, I had to read your post a second time to get what you were saying... but I agree:

We, as DRPA owners certainly do stand by the product. I think the real reason is because I've never had anything go wrong with it and it's never caused any problems. In fact, it does what 5 or 6 other units would do for me, all in a 1U space which is perfect for a Mobile DJ. My sound is better and my setup is simpler. I have enormous control over the dynamics and quality of my audio performance, as compared to DJs that rely on nothing at all, or perhaps the 3-band or 5-band EQ in their mixer to help things out!

I also agree that the DR260 isn't a "fix" for the DRPA -- it's so much more!
The DRPA is an excellent value in the $450 range in that it includes so much and does it so well. The DR260 is really the next step up in that it adds more features and flexibility.
The DR260 is in the < $999 range, and is what I'll consider getting if I ever feel I want those extra features.

As for "fixing" the DRPA -- if they did that, then everyone would want one, and I doubt DBX could keep up with the demand. :lol:
