You're thinking of HyperMAC (as opposed to SuperMAC, which is what Sony called the 100 Mbps version before it became an AES standard); strictly speaking, the 1 Gbps version has never been incorporated into the (royalty-free) AES50 standard, so "AES50" refers only to the 100 Mbps version.

Not sure who to answer to but here is a rundown on AES HyperMAC and SuperMAC.

MAC's

Cable requirements have changed through the years so it is good to note that.  ;)

Hi all,

Has anyone here used L'Acoustics A10s? Looking at maybe having 4x A10 wide and 2x KS21s all powered with 2x LA4x amps. Not looking to fly anything at this point as 95% of my events are ground supported PAs. I have never used L'Acoustics before. I downloaded the Soundvision software and was completely lost. Much different compared to LAC and ArrayCalc.

What's the throw on these boxes like?
How do they sound?
Would a 1 over 1 or 2 over 1 be sufficient for a band gig and possible DJ. No EDM, hip hop.
The biggest room I provide sound for is 60' wide by 120' deep.
How's the accessories in setting these up etc..

Looking for Pros and cons of this rig.

TIA

I run an A15/KS28 rig, but I have A10's for my delay fills.

I am not sure what type of SPL your are looking for, and what amount of front to back variance is acceptable for your gigs, but I don't think you are going to get 120 feet of coverage with them, especially ground-stacked - in my room my hang of 4x A15's are shooting about 70ft-100ft, and that seems about right.

As these boxes are constant curvature that minimizes some of your options vs a line array.

The boxes are L'Acoustics, so they sound nice, I cannot complain - while they might look somewhat similar to VRX they are different animals.

---

One other curiosity I have is I that have occasionally worked on a A10 rig where the boxes seem to overlap and get harsh between boxes; it was a nature of the array, as it is not splayable. I heard from the integrator who installed that rig that this was due the box not being the install version, and that the install version has an available bumper - but I have not been able to verify that one- in that particular system a point source would have been cheaper and sounded much more consistent both for SPL and frequency.

Granted the A10's in my delay fills don't have this problem though - so not sure why.

---

Bottom Line: They sound nice, but I would probably be looking at a different rig for this application.

The Dynacord DSA8212 amp would work fine bridged mono into a single 4 ohm TH-118.
You would need three more if you want to use the dynamic range the TH-118 can handle.
Their peak power of 3400 watts is good, but as Paul (and Ivan) have suggested the long term limiting should be set to about 1/4 that.

That was my take as well based on the specs but others suggested it might be OK to run one sub per channel? I guess I just  try it out and listen?

In the post below Ivan also suggests that two TH118s can be ran from a single DNA20K channel. Would that be roughly equivalent to a single TH118 on one DSA8212 channel or is my math completely off here?

Just 1 DNA20K.  It is 4 channels that are 5Kw each @ 2 ohms.

If you are running a mono system, then you could run 6 TH118s and 4 SM80s off of a single amp.

So that would be all 4 SM80s on 1 channel and 2 TH118s on each of the other 3 channels.

That is "assuming" all the SM80s are getting the same signal.

Who me?  I need DSR112 power amp.

Thanks!

Ha! Is there any certified shop with techs that know their sh.... So those amps can be repaired, wish Yamaha or some body make em at least to replace broken ones, or you send the bad one and they sent a refurbished one

{...} One thing I was wondering and sort of alluded to: The X/M consoles' AES 50 can carry 48 audio channels each way. Is there any combination of use circumstances that uses that channel count to full capacity both ways? I can't think of any.

Given that you can route 32 channels of bidirectional audio directly between the card slot and an AES50 port (in addition to the DSP and any local I/O), I think the answer to this is "technically yes, but why?". :P

Fair enough. I've always referred to the "Y" splits as passive for some reason, though I've never thought of or referred to a transformer split as "active", so I guess it's a meaningless descriptor in that context.

..except that it's not meaningless: as Tim mentioned, active splits (i.e. audio splitters that involve an amplifier stage) are absolutely a thing, but the use-case for them is vanishingly small (although not nonexistent; for example, they're exactly the sort of "reliability through frivolity" that broadcast loves to throw its money at).

Hello,
I have two JTR Orbit Shifter subs (2021 model) and two Noesis 3TX (2016 model) for sale.
The subs have been used for 6 shows since purchased. I had sold my previous set for an install and upgraded to these. The Noesis are in excellent condition with no issues. I replaced one of the compression drivers in 2023. They also come with Underground padded covers & rain covers. Excellent speakers, I am consolidating equipment and scaling down as I now own a venue.
$7500, shipping not included. Located in St. Petersburg FL. Pictures on request, they are too big to upload here. Thank You

I’ve done some searching but not much info online.  Has anyone actually used a Bassboss system?  I was looking at the AT212-MK3 and dual-18 subs system.  It seems it would be a good medium system, like the JBL SRXs.  It has a lot of good DJ accolades but not much live band experience.  Thoughts?  Any experiences with full bands and outdoor venues?

Yes that would be the AI spellcheck.  Was in line at Lowe’s, sorry

At the risk of being called ultra pedantic, hardwired and transformer isolated splitters are both "passive" ;-)

I got called out on the terminology some years back...!
