    wireless systems
    Craig Leerman 03/07/12 10:49 AM,
    The early history of the development of wireless microphone systems is a bit murky as to “who did what and when,” but it might be surprising to know that they’ve been around in various forms for more than 60 years. In fact, back in the mid-1940s, publications such as Popular Science showed schematics and kits for making low-power wireless microphones that could transmit to a nearby AM radio. The Shure Vagabond system, which debuted in 1953, most certainly was one… View this story

    loudspeakers
    PSW Staff 02/17/12 12:55 PM,
    When I started working with audio, most companies built their own main and monitor loudspeaker enclosures. Some did it because it could save them money, but the majority did it because they wanted products that were simply not commercially available, so they had to design and build the systems themselves. Today there are a multitude of loudspeaker companies making a wide variety of different enclosures – with more designs hitting the market seemingly every week – but there are still… View this story

    When it comes to loudspeakers for professional audio applications, line arrays get the glory and much of the press, but traditional 2-way boxes are still the real workhorses of the business. They remain invaluable for a range of very good reasons, with versatility that translates to “great bang for the buck” topping the list. A quick check of manufacturer websites bear this out as well. Again, the latest line array might be the “next big thing” touted on the home… View this story

    microphones
    Craig Leerman 11/14/11 04:11 PM,
    Long ago, an old sound guy imparted to me words of wisdom about the optimum way to mic instruments: “Pick your best microphone, put it on your best stand, place it in the best spot, point it in the best direction, and hope for the best.” That statement seems a bit trite, but it also contains truth. So where do we start in this pursuit of the “best” in all aspects of instrument mic’ing? While it’s true that vocal mics… View this story

    amplifiers
    PSW Staff 10/24/11 02:15 PM, 0 Comments
    The common “wisdom” just a few years ago was that the emergence of self-powered loudspeaker lines with enclosure-mounted amplifiers and protection circuitry tuned specifically for the loudspeaker meant the days of rack-mounted power amplifiers were numbered. But it’s funny the difference that innovation can make. Today’s amplifier is a powerhouse, light years removed from the huge, heavy and inefficient designs of the recent past. Current designs are also far lighter, and in some cases, come in a compact package that… View this story

    cardioid subwoofers
    PSW Staff 10/14/11 11:14 AM,
    Ever since the introduction of line arrays, it has become harder for subwoofers to keep up with the efficiency of tall columns of coupled transducers in large full-range systems. This has helped drive transducer and amplifier manufacturers to produce increasingly powerful low-frequency components. Multi-kilowatt dual-18 enclosures are now the standard. However, while flown full-length line arrays do a superb job of getting full-range sound to the back of enormous venues, stacked subwoofers – even with their advantage of half-space coupling… View this story

    In the not-too-distant past, professional touring systems consisted of two or three remotely located consoles, tied to a combination of low-level passive or dynamic input sources (along with some active or phantom-powered inputs), connected by long lengths of multicore snakes, through a system of transformer-isolated or (yikes) passive hard-wired splitters. The effect on low-level signals with multiple consoles and long lengths of multi-core is a reduction in signal level, higher noise floor and less bandwidth. The most vulnerable points for… View this story

    loudspeakers
    PSW Staff 09/21/11 02:16 PM,
    This month we look at line source column loudspeakers, which are also sometimes called “architectural” loudspeakers, presumably because their slim-profile design allows them to blend well into their surroundings. Despite their rather scant appearance, however, many modern column loudspeakers deliver exceptional full-range performance, and this can be furthered by companion LF boxes and subwoofers. There are two primary types of column loudspeakers – those that offer the ability to “digitally steer” the vertical beamwidth and those that don’t. But it’s… View this story

    line arrays
    PSW Staff 09/07/11 02:35 PM, 0 Comments
    In this Real World Gear installment, we look at “compact” line arrays, which we’ve defined as those with 8-inch (and smaller) LF drivers. Previously we applied this designation to “small and mini” models; however, the market is evolving so quickly and dynamically that attempts to put together “like” groups of line array modules under a precisely defined criteria is fast becoming a thing of the past. The fact is that one company’s “small” is another’s “mini” is another’s “compact” –… View this story

    Vocal microphones are most entertainers’ and engineers’ introduction to sound systems, their first point of contact and the first piece of equipment that they purchase and carry with them. The vocal quality is of paramount importance in most sung music, and the easiest way to improve it is often to change vocal mics. Dynamic mics use the same principle as a loudspeaker, except in reverse. A diaphragm attached to an induction coil is positioned in a magnetic field. Sound moving… View this story
