    subwoofers
    Craig Leerman 12/08/13 12:35 PM,
    While we tend to think of extended bass as a modern invention, audio folks have been expanding frequency response for decades. Way back in 1932, A.C. Thuras received a patent for a bass reflex ported design, and in 1934, Andre D’Alton was granted a patent for a bandpass design. However, true separate subwoofers (dedicated band-limited enclosures with cone loudspeakers for frequencies generally below 100 Hz) did not become commonplace until the 1960s, and even then were mainly used in limited… View this story

    power amplifiers
    PSW Staff 12/02/13 11:48 AM,
    There’s a lot to like when it comes to modern power amplifiers, and a variety of options abound. They provide tremendous power from far lighter packages, and in many cases, resemble a rack-mount processor more than a device capable of generating several thousand watts of audio power. The primary advancement in terms of power is efficiency. Greater output efficiency means less heat, and therefore, less weight, as well as more AC power making it to the loudspeakers. The most common… View this story

    In the past year or so, several major players have introduced digital wireless microphone systems, ranging from entry level to professional units. While generally maintaining the traditional form and functions of the products, engineers have adapted concepts and techniques from computer networking, cellular telephones, and digital signal processing to enhance their performance. Expect this trend to continue, since the new technologies can provide advantages in dense RF (radio frequency) environments, as well as generally excellent audio quality. And in some… View this story

    microphones
    Gary Parks 09/11/13 10:19 AM,
    Expanding on the basic technologies of dynamic and condenser transducers, manufacturers continue to develop new microphones to meet the needs of musicians and sound engineers in a range of formats, sizes, and price points. In more recent introductions, we’re seeing a mix of innovative development, refinement of previous technologies, specialization of mics to specific applications, and changes in manufacturing.  Higher end condenser vocal mics are truly amazing devices, and even most of the relatively inexpensive models are durable, reliable, and… View this story

    digital consoles
    Craig Leerman 02/15/13 04:50 PM,
    Simply put, the market for compact digital consoles has exploded. Manufacturers are offering an increasing number of smaller models, which can also provide additional advantages that include lower prices and ease of transport. Not every gig requires a ton of inputs, and not every portable show and venue has need of a larger control surface. A lesser footprint doesn’t necessarily mean that commensurate feature sets are lacking. Many models utilize the same high-end components and accessories of their larger siblings,… View this story

    For decades, compact 2-way loudspeakers have been a pillar of professional audio, capable of serving as mains, monitors, side fills, center fills, near fills, front fills and delays. Usually they can be carried by a single person via convenient handles and quickly ground stacked, flown, or placed on a stand, where they’re capable of handling reinforcement all by themselves or joined by subwoofers in applications requiring additional low-end reinforcement. Many of these boxes are trapezoidal in shape, with some able… View this story

    real world gear
    PSW Staff 11/20/12 10:59 AM,
    A live music system usually isn’t complete without subwoofers. Whether horn loaded, cardioid, bass reflex, infinite baffle, or band pass, they are a bedrock of pop and rock music, as implicit as the kick drum mic in channel one. Though initially developed to extend LF response in the 1960s and to enhance supplemental effects for 1970s disaster movies, subwoofers – dedicated band-limited cone loudspeakers for frequencies generally below 100 Hz – have grown to become the most ubiquitous specialty enclosure.… View this story

    power amplifiers
    PSW Staff 10/10/12 06:01 PM,
    In the classic sci-fi TV series Star Trek, Captain James T. Kirk of the Starship Enterprise frequently implored his chief engineer, Mr. Scott (a.k.a. “Scotty”), “We need more power!” And Scotty always did his best to comply with the captain’s request, regardless of the complications of the situation. Sound reinforcement system designers and engineers have made similar demands of power amplifier manufacturers, and like Mr. Scott, they’ve come through, and in spectacular fashion. The modern power amplifier is light years… View this story

    line arrays
    PSW Staff 09/30/12 09:25 AM,
    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. Generally speaking, products in this genre offer a relatively small footprint in terms of size, weight and cost. They’re conveniently portable due to the size/weight factor, but are suitable for fixed installations as well. For dynamic full-range music presentation, compact arrays are usually accompanied by at least one subwoofer. In addition, the vast majority of full-range models… View this story

    microphones
    PSW Staff 08/14/12 04:20 PM,
    While it’s true that vocal microphones can do double duty on instruments, only select models do both jobs well. Simply put, vocal mics are optimized for voice – many have a presence peak, or a boost in a band of upper midrange frequencies. This enhances the articulation and intelligibility of voices, but when applied to instruments, it can add coloration that’s detrimental. Vocal mics also tend to roll off lower end frequencies (below the voice range) to help eliminate handling… View this story
