Members musicnmotionz Posted January 4, 2014 Members Share Posted January 4, 2014 I was wondering why the GX7 is priced below it's PLX counterpart, the 1804? Are the components of equal quality? Also, I need to run a 50Hz HPF (for my speakers' longevity). What's the best most economical way to do this with the GX7, since it does not have built in HPF? (use a Driverack?)Lastly, what's a good price for a used unit in good working condition? Any help will be much appreciated! Thanks! Link to comment Share on other sites More sharing options...

The GX7 does not support 2 ohms, is lower (total) power, does not have the signal processing features that the PLX does, this is one reason why it's less expensive. They are also built differently, the GX series is much harder to service than the PLX, therefore perhaps more expensive. For a HPF, something like the DRPX is a good choice. If you are biamping, then the HPF is contained in the High Out x-over filter. What speakers are you using? Link to comment Share on other sites More sharing options...
Members musicnmotionz Posted January 4, 2014 Author Members Share Posted January 4, 2014 EAW LA212 speakers.Is the GX7 a good match? I could purchase a good used unit for $300. Link to comment Share on other sites More sharing options...
Members mkfs9 Posted January 4, 2014 Members Share Posted January 4, 2014 Just get a qsc rmx amp with one built in. Link to comment Share on other sites More sharing options...
Members Tomm Williams Posted January 4, 2014 Members Share Posted January 4, 2014 As you are probably aware, the 4 series offers less features than the 2. I believe the plx3002 is in the same power range as an 1804. I've seen a number of them used at GC for 399.00. 2 series has switchable filters . 4 does not.

CMS Author Craig Vecchione Posted January 4, 2014 CMS Author Share Posted January 4, 2014 Planning depends on the details. How are you using the LA212's; fullrange front of house, biamped with subs for front of house, or as floor wedges?If they are being using fullrange, I would suggest you consider an amp that has HPF's built in. The RMX series has them, and cost is comparable to the GX's, but these amps are heavy. The PLX series are lighter and have the HPF's. Long-term I'd suggest the PLX.If the LA212's are being used as part of a biamped, system, then a driverack would probably cost efficient, as you'll need at least a crossover in addition to HPF's. In this case a GX series amp works out fine. Link to comment Share on other sites More sharing options...
Members Tomm Williams Posted January 4, 2014 Members Share Posted January 4, 2014 I'm surprised at the price I still see used RMX's going for. You would think they would be dirt cheap but not so in many cases. I would spend the extra $$$ and look at PLX if you need the features. I have a pair of 3602's and three 1804's. Each have their place but I really like the extra features on the 02 series. Link to comment Share on other sites More sharing options...
Members agedhorse Posted January 4, 2014 Members Share Posted January 4, 2014 The RMX has a reliability track record going for it, there are still some folks who don't (yet) care about weight. Link to comment Share on other sites More sharing options...

Members musicnmotionz Posted January 4, 2014 Author Members Share Posted January 4, 2014 Yeah, I hear you. I'm 26 years old, and I've made a decision to stick with amplifiers under 25lbs and speakers under 55lbs. I'm currently using a QSC CX702 amplifier with the EAW LA212's. It's my living room sound system at the moment. But when I have to disconnect and move everything for the occassional gig, the barrier strip terminals are a pain. Plus, the amp makes a huge "POP" sound (heard through the speakers) when I turn off the power switch. Any ideas why that's happening? Thanks for all the input so far!

Members Tomm Williams Posted January 4, 2014 Members Share Posted January 4, 2014 26 !!!!! Sonny I didn't shed my RMX until I was 50 !!However I didn't start doing this until I was about 45 and super light amps didn't exist. Ah the good old days , no wonder my back always hurts.

Members agedhorse Posted January 4, 2014 Members Share Posted January 4, 2014 When you turn off the amp's power switch or by chance are you turning off other power switches at the same time??? Link to comment Share on other sites More sharing options...
Members mkfs9 Posted January 5, 2014 Members Share Posted January 5, 2014 Turn your amp on last when setting up, and first when shutting down, turning down first aswell. Link to comment Share on other sites More sharing options...
Members musicnmotionz Posted January 6, 2014 Author Members Share Posted January 6, 2014 Even with the gain controls all the way down, it still does the POP. Even with no inputs into the amp. This only happens when I turn the power switch OFF. Any ideas? Link to comment Share on other sites More sharing options...
