    Electromagnetic interference, often referred to as EMI, is a degradation of the performance of a piece of equipment or system caused by electromagnetic radiation. Electromagnetic radiation is the travel of alternating electric and magnetic fields through space at 186,273 miles (about a billion feet) per second, or the speed of light. A wavelength, as shown in Figure 1 below, is the physical distance traveled by a wave during one cycle. When the equipment or system is closer than about a… View this post

    Before beginning the design process for a business sound system, identify what the customer needs and expects: Fidelity Expectations. Does the client want a good, basic system; something a little better than average; or maximum bandwidth and maximum fidelity? Sound-Level Requirements. Will the system be used strictly for background music, or does it really need to rock? Usage. What kind of music will be played through it? For example, if it’s urban funk, then you’re going to have to think… View this post

    Altinex has announced the new TNP155 and TNP155S Tilt ‘N Plug Jr. interconnect boxes, providing one-touch access to dual AC power receptacles plus two charging USB ports and available in both standard and custom configurations. As a tabletop connection device, the Altinex TNP155 (brushed black finish) and TNP155S (clear brushed aluminum) are highly functional tools for accessing conventional AC power outlets for the purpose of powering, for example, a notebook PC. Similarly, the dual USB ports are capable of charging… View this post

      The crest factor of an audio signal is the dB difference between the peaks and the RMS value of the signal. The RMS (Root Mean Square) is defined as the “heating value” of the signal - the voltage that would generate the same heat as a DC (Direct Current) signal, over the same time. The RMS value of a complex signal must be read with an RMS voltmeter. Alternatively, the signal can be digitally sampled and the samples summed… View this post

    New Crest Audio CLh Series power amplifiers for fixed installation applications are now shipping. Led by the CLh 5000 and CLh 2500 models, CLh amplifiers are outfitted with an efficiency amplifier output circuit that reduces weight while increasing output power, reliability and thermal efficiency. As servo-controlled, highly efficient, class-D power amplifiers, the CLh 5000 and CLh 2500 deliver power through two channels to balanced outputs for high common-mode noise cancellation. The CLh 5000 produces 2,500 watts per channel continuous at… View this post

    John Meyer was awarded the Adele De Berri Pioneers of AV Award at InfoComm 2014 in Las Vegas. Since founding Meyer Sound in 1979, Meyer has led an engineering team that has advanced sound reinforcement through the design, manufacture, and use of linear loudspeakers. While many of Meyer’s innovations appeared radical at first, many of his ideas have become industry norms. This includes Meyer Sound’s self-powered loudspeakers, a breakthrough for the company when first introduced in the 1990s. Meyer also… View this post
