Dave Rat Transmission: Smart Amplifiers =  Huge Changes In Professional Audio
With manufacturer-specific smart amps (and also increasingly, powered/processed loudspeaker systems), there's an opportunity for a fundamental shift in exactly who really has control of the starting-point sound of a PA system.

Are external digital processors just a band-aid, like what we see with our laptops when a new technology comes out?  Remember external modems that used the now nearly extinct 9-pin serial port?

Over time with laptops, most “things” moved to inside the package, and now even in our own industry, digital consoles are gobbling up stand-alone compressors, gates and EQ.

So how far fetched is it really that the amplifier will eat the digital processor? It’s not.

In fact, for several years, a number of leading amplifier manufacturers have been offering a number of options for onboard processing, monitoring and other capabilities, usually in plug-in card form. 

NEW STANDARDS
At the same time, the sheer power output capability of modern amplifier technology is remarkable, and even more so when considering size, weight and channel count.

When I began working in pro audio in 1980, the state-of-the art amplifier was a four-rack-space unit (such as this one - pdf file, by the way), which delivered a then-whopping 700 watts per channel into 2 ohms while weighing in at a “feathery” 57 pounds.

Today, we have 10,000-watt, 4-channel, processor-equipped units of just two rack spaces and less than 30 pounds, and even this “wonder spec” won’t remain amazing for much longer at the rate the technology is being improved.

Just as stereo replaced mono, 4-channel amps are positioned to become the new standard, with 6- and 8-channel versions not far off.

Funny maternity clothes need not necessarily be expensive, as you may get funny maternity t-shirts for less than $30! There are t-shirts that have inscriptions such as "not in a good mood", "baby on board", "I'm pregnant, what's your excuse?", " I'm making a human, what did you do today?", "Already smarter than Bush", "I just wanted a back rub" etc. There are funny clothes available for the father of the child too, with funny inscriptions such as "See how my boys swim,” "Man behind the belly"; "My pregnant wife scares me" etc.

Commercial carpet cleaners might be a money waste, as their cleaning effectiveness can easily be achieved with a good, inexpensive homemade all-purpose carpet cleaner. The chemicals that different store-bought carpet cleaners contain, might be another reason to prefer using your own cleaning solution. Here are some tips how to make an all-purpose carpet cleaner with products you probably already have in your home.

The main idea of online shopping is not just in having a good looking website that could be listed in a lot of search engines or the art behind the site. It also is not only just about disseminating information, because it is also about building relationships and making money. Mostly, cisco braindumps / cissp braindumps / citrix braindumps / comptia braindumps / crm braindumps / cwna braindumps / db2 braindumps / itil v3 braindumps organizations try to adopt techniques of online shopping without understanding these techniques and/or without a sound business model. Rather than supporting the organization's culture and brand name, the website should satisfy consumer's expectations.
