Bessie Posted October 24, 2010 Share Posted October 24, 2010 Hi all, first post round here. Want to see if anyone can be of assistance. Has anyone had much to do with L Acoustics LA8 and LA4 amplifiers? I've used LA4s with 12XTs and found them to be pretty good. Has anyone used them with dV-DOSC? I've heard various people talk of how they don't cope very well, but its generally been said as a rather sweeping statement. I've heard dV driven by Labs and its been rather lovely. I don't think the LA8/4s are actually produced by Lab Gruppen like the LA48s used to be. Correct me if I'm wrong. Also has anyone heard any L Acoustics boxes through the MC2 E Series - E25 / E90s etc... Any opinions much appreciated, facts even more so :D Thanks Link to comment Share on other sites More sharing options...
Wilflet Posted October 24, 2010 Share Posted October 24, 2010 Has anyone used them with dV-DOSC? Its fairly common and always sounded fine to me. Link to comment Share on other sites More sharing options...
Bessie Posted October 24, 2010 Author Share Posted October 24, 2010 Yes. I realise its fairly common. L Acoustics do make them for use with their speakers. :D I'm interested in how they compare to the older Lab Gruppens (LA48s). And anyones experince of the systems with other amplifiers. So you say they sound fine, not great then eh? Link to comment Share on other sites More sharing options...
Simon Lewis Posted October 24, 2010 Share Posted October 24, 2010 For the facts about the Lab Gruppen amps, it would be worth asking Simeon Ludwell... Link to comment Share on other sites More sharing options...
waster Posted October 25, 2010 Share Posted October 25, 2010 The LA4/8 is made in conjunction with camco. They are good amps. I work in a venue that has dvdosc powered by LA8's. I can't compare it to LA48's but nobody who comes through complains about the amps. If you are looking to buy amps to go with a dvdosc system or any l-acoustics system I think it would be foolish to buy anything other than the LA amps. It keeps it all more rider friendly, cross hire / sub hire friendly and also allows for the use of LA network manager for system eq, delay etc. Link to comment Share on other sites More sharing options...
nb705 Posted October 25, 2010 Share Posted October 25, 2010 I've used Dv-Dosc with both LA8s and with Lab FP6400s with XTA and DLP processing. There is a noticeable difference in how the box sounds, and how loud it appeared to go too (I haven't had the time or the opportunity to perform objective measurements). I found the LA8s to be a touch louder and sound nicer, not only that but the LA8s are lighter and are 4 channels with builtin processing, reducing the size and weight of your amp racks.

Bessie Posted October 26, 2010 Author Share Posted October 26, 2010 Now thats the kinda response I was after. You work in a venue with dV and you're from Nottingham... must be Rock City, right? The dV Subs are flown there yes? Am I also right in thinking there's some SB218/SB28s on the floor. How do you find the combination of 15s and 18s for low end? Not really experienced the two together apart from in Turbosound Aspect and I was impressed then. Though that system was driven by MC2 amps which just rocked it. E90s on the 2x18s, great stuff. "I found the LA8s to be a touch louder and sound nicer." Interesting you say that as I have heard people say the exact opposite. Maybe it's just one of those things.

Wilflet Posted October 27, 2010 Share Posted October 27, 2010 How do you find the combination of 15s and 18s for low end? Not really experienced the two together apart from in Turbosound Aspect Im struggling to think of a 4 way system Iv mixed (and been happy with) on that dosnt include both. nexo alpha, arcs on sb28 (and a stack of DV, on some DVsubs, next to some 218s for that matter), kf850 over 18" subs.... *With the LA amps you get the option to choose a few profiles for alot of boxes, so you can choose what frequencies each box does, the DVsub and SB arnt nescercarily competing on the same frequency, it might be closer to a 4 way system depending on profiles... though from what iv seen of the rock city set up for alot of bands Id possibly want to view it as a Dv/DVsub full range out with ground subs on an aux. Referencing my earlier post 'Fine' probably understated it, I consider it the normal way of doing it, and given the previously stated advantages of weight and U space and savings in signal distribution and processing along side cross hire ability I beleive it would take a hell of a good sounding amp- to the point Im atleast yet to here and not entirely convinced can be made- to overcome to advantages of the LA8 Link to comment Share on other sites More sharing options...

Yes I'm a House Engineer at Rock City working in the main hall that has the SSE installed dv-Dosc system. The system is 8 flown dv-Dosc a side. We have LA Network control over it in three zones (2,3,3). 2 flown dv-Subs on the outside of the dv-Dosc hangs. Then 3 SB28's on the floor per side. 3 LA8's on the dv-Dosc, 2 LA8's on the dv-Sub, 2 LA8's on the SB28's. We use a Yamaha DME to route signal to the amps. We can configure it to allow touring productions to have indvidual control over all 6 outputs (dv-Dosc L/R, dv-Sub L/R, SB 28 L/R) or just a L/R feed in. We can do the SB28's off a seperate feed. The dv-Subs work well and add punch. We run the dv-Dosc down to 100Hz. dv-Subs run 100hz - 60Hz. Then SB28's take over 60Hz down. We use LA Network Manger to provide EQ over different zones of the PA should engineers require it. All Time Alignment is done using the amps processing. We just use the DME for routing. It is a very good system. Link to comment Share on other sites More sharing options...

As I said, I haven't been able to perform objective measurements. However, it might be worth noting that L'Acoustics have been releasing various firmware updates for the LA series amplifiers that can have a big impact on how they sound.

organised confusion Posted November 1, 2010 Share Posted November 1, 2010 The LA8's are great, and finally brings L'Acoustics up to speed with the likes of d&b. You can't buy LA48's new now any way, they did offer to build us them especially for our dV's in my last company, but that was because we were a V-dosc partner. Doubt they would do it for many people. Link to comment Share on other sites More sharing options...
