PSW Staff 05/08/13 02:53 PM,Ashly Audio has introduced the new nX family of Class D amplifiers, which deliver up to 12,000 watts while drawing less than 1 watt in sleep mode. These latest amplifiers are back by a heritage stretching back to Ashly founder Billy Thompson’s invention of the “Loud Amp” in the early 1970s and the introduction of its MOS-FET amplifier technology in the early 1980s. nX amplifiers are offered in four- or two-channel versions with selectable high-Z (70/100-volt) or low-Z output on… View this story

Bill Whitlock 04/16/13 06:01 PM,“A cable is a source of potential trouble connecting two other sources of potential trouble.” The humor in this statement may be lost on those who regularly assemble sound systems. But a reality of sound systems is that a signal accumulates noise as it flows through equipment and cables. And once noise contaminates a signal, it’s essentially impossible to remove it without altering or degrading the original signal. For this reason, no system can be quieter than its noisiest link.… View this story

PSW Staff 04/16/13 05:48 PM,Bose Professional builds on its proprietary PowerMatch technology platform with three additional models of configurable professional power amplifiers. Configurable through the use of QuadBridge technology, each amplifier is capable of combining 2 or 4 output channels, creating flexible options to drive different power levels and loudspeaker impedances. “Building off customer feedback we’ve received during our first 18 months with the PM8500, we developed three new models with different channel and power levels—all leveraging the same great performance, efficiency, and reliability… View this story

Dobil AV sales engineer David Rosenberger explains, “We’ve been refreshing a lot of their older AV systems which isn’t uncommon given newer digital technology and the industry having evolved from coaxial to the twisted pair and IT world. We’re getting more into network switchers and control processors and we have to power… View this story

Mike Sessler 02/20/13 10:11 AM,This article is provided by ChurchTechArts. The topic for today’s post comes from a reader, Jonathan Mould. He wanted to know more about the electrical side of sound. This is an interesting topic because sound is both electrical and physical. Sound systems turn physical movement of air into electrical signals, then process and amplify those signals (sometimes changing them into streams of 1s and 0s and back), and finally turn those amplified signals back into physical air movement. It’s… View this story

Craig Leerman 02/15/13 02:29 PM,Festival season, in particular, means dealing with portable generators for show power. At performance venues, we hardly give power a second thought, simply handing our tails or feeder to the house electrician to tie into the “company switch.” Then we check the voltages at the distro end with a meter to make sure everything is connected properly, and that’s usually it – no more thinking about the power until it’s time to disconnect at the end of the gig. The… View this story
