Pro audio forum comedy

I'm officially a troll for asking a simple question on the pro sound forum.

Two links;

If you ever feel bad that you are not skilled enough in DIY audio, just

hang out there for a week and be amazed at how much you really know

vs. them //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Should point them in the direction of the many car audio and home audio amplifiers capable of driving such loads.

Apparently PA is the only audio field that considers it "unnecessary".

I didn't know a 2 ohm mono load was so low //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

"in bridged mode."

Are your only wiring options 2 ohms bridged? What about 8 ohms bridged. QSC has the PowerLite 6.0II that will deliver 4400watts into an 8 ohm mono load. It will deliver 7000 watts into a 4 ohm mono load. If you go into 2 ch mode you get 2200watts a side at 4 ohms and 3500 at 2 ohms.

It is. In pro audio. Most drivers in PA are only SVC and many are 8-16ohms. Very few 4 ohm drivers (mostly subs). Also in pro audio, remember that each driver usually has its own amp channel so that you can properly delay and align each driver. So in essence a 2 ohm load in PA is a very low load. Usually we try to keep it at 4ohms.

Given two choices over in that forum;

1. Run a low impedance loads {1 ohm stereo, 2 ohm bridged}.

2. Have *** with a shemale.

Which is worse for them ?

The issue is not about how to make the system work, it was a question

to find out who make a stable 2 ohm amplifier bridged. I know what my options are //content.invisioncic.com/y282845/emoticons/cool.gif.3bcaf8f141236c00f8044d07150e34f7.gif ... I want a reaction from ''' them ''' ...

I think the real issue is;

1. Users don't want heavy amps. Who wants to haul around many 150 pound

ampifier to a gig ?

2. Who wants a stacks of 4RU, 6RU or 8RU monster amps ..

3. Who has the AC mains to supply these monster amps?

So.. in the pro audio world it's better {ideally} to make lighter amps, preferrably

power programmable amps.. and you can't make a 1 ohm/ch stable amplifier

in a 2RU size that will play sine waves all day, you can probably make one to

play music only.

Hypothetical -> Lets say I have four 8 Ohm woofers in a stack, 70" tall.

2 Ohm load as all driver are in parallel. I don't see a reason to delay

the signal to each woofer being that they are close together in an array.

I could rewire this array for 8 ohms vs. 2 ohms but you loose array sensitivity,

that's not fun for the 'power user' like me who does this in the home, but

obviously not done in pro audio.

/harr harr

If I was doing DJ work and had my own stacks of 15's and made 1 ohm stable amplifiers

and the venue has AC mains to support this.. hell yes I would hook it up this way to punish

everyone.. show no mercy. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

The *** with a shemale would never happen. Rather, they'd begin a never ending monologue about how a shemale has little utility, and that either a male or female would be infinitely better in function.

 

[JimJ 5,000+ posts]

At least it's better than on AudioAsylum, where they would argue that in a blind ABX test, you'd never know the difference between the shemale and otherwise.

Followed by twenty replies saying they preferred *** with the shemale, although they concede to have no personal knowledge of it.

Of course.

We used to run 1 Ohm a side for some setups on a Crest 8001 and never ever ever had any problems. You could also drop a Series III 3500 QSC down way below its "rated" stable ohms point and drive the pants off it and it would just laugh at you asking for more. And same thing with let see QSC MX-1500a, MX-2000, H||H Audio V800, Crest 10001, could do it with a Clown (hm hm I mean Crown) but you might get a DC problem if you don’t watch. It goes to show the guys who think they have done everything and the guys who have done everything. Thank god I'm a 3rd generation experimenter with audio!! (NOTE: NOT RESPONCIBLE FOR FLAMING AMPLIFIERS, SPEAKERS, CABLES, OR POWER BOXES. EVERYTHING IS DONE AT YOUR OWN RISK)

The key is music vs sine wave testing. I did both and sine wave battered the amp

on an abnormal load.

Sine wave testing at 2.8 Ohm bridged blew the IGBT switcher transistors

on a burp, with clipping. But I play music all day with 0.8 Ohm tweeter load

in bridged, 2 Ohm midrange load. PLX doesn't complain.
