Cheating? Really?

Note: This was written in response to Baker Lee’s “FOH At Large” column (June 2012 FOH) regarding the occasional dangers of technology and whether depending on various devices represented a form of “cheating.” We thought Kip presented some good points and we wanted to share them with you. —ed.

As I sit typing this on my MacBook, I start to wonder if I am “cheating” by not picking up a pen and paper, purchasing a stamp and driving a letter to the post office. All things that, in this economy, I would prefer not to do.

Microphone Innovations: The Problem, the Process and the Prototype

Since I made the choice to migrate from analog consoles to a digital platform, something that’s become increasingly clear to me is the requirement to be even more selective and judicious in my microphone choices. I believe it’s reasonable to conclude that the process of digital conversion after the mic preamp is maximized when the processor engine is provided with the highest possible degree of useful detail from the transducer. In the last six years, I have been adding more and more precision high-end condenser, ribbon and dynamic microphones to the James Taylor show’s input list.

Saint Monitor

Where do monitor engineers go when they retire? That’s easy: they go to heaven. After dealing with all of the crazed artists and onstage insanity that comes along with creating multiple mixes for performers with widely varying needs, they deserve it. Yours truly does not fall into either category (monitor engineer or heaven), but that doesn’t mean that we can’t dig out tips and techniques to help you in your quest to create a better stage experience for the artists with whom you work.

On toms and snares, a cardioid dynamic (such as this Sennheiser e904) — placed slightly above and near the edge of the drum head — offers good tone with little bleed or feedback problems.

Microphone Techniques for Houses of Worship

Probably the most overlooked issue in house of worship audio is the placement of the all-important microphone. This issue is mostly confined to instrument microphones and choir mics. With regards to speaking and individual singing mic placement, the issue here is usually the end user. However, we will discuss this later. For now, let’s turn our attention to instrument miking techniques. There are a few different ways to mic almost every instrument. So I am going to tell you my tried and true methods, whether it be drums, guitars, bass, brass, etc.

The Language Tool: The Other Side of the Spoken Word

Call me archaic, but I actually find the English language to be a great way to express one’s thoughts — regardless of intent or purpose. From relaying simple instructions in concise terms to loquaciously waxing poetic, English — when used properly — is capable of conveying thoughts and feelings with nuance and elegance. This does not mean that we need to roll our “R’s” nor speak in Shakespearean English, but as intelligent people, we must find a middle ground between “Wherefore art thou?” and “Where you at?”

Soul of a Tradeshow

It’s been a couple weeks since InfoComm 2012 and by all accounts, this year’s event was one of the most successful shows that organization has presented in recent memory. (Note: For highlights and insights on InfoComm 2012, CLICK HERE). Attendance was up, there was no shortage of new technology, new tools and new toys to check out, and the vibe among attendees — both exhibitors and visitors — was uncompromisingly positive. All of the above are good signs that bode well for the overall health of the industry.

Understanding Crossovers

Every year brings more processing power to all aspects of live sound. Modern loudspeaker processing routinely employs equalization, delay, crossovers, limiting and other advanced DSP processing techniques, such as FIR filters. DSP can be found in standalone processors, in amplifiers or built into powered speakers.

SIA Acoustics Helps Shape the Sound in eTown’s New Performing Arts Facility

It starts with a phone call… or an email. “I want to build a studio or a sound stage or even a concert hall.” Usually, it’s the owner, just starting out and wondering how to move forward. Sometimes, it’s an architect or even a construction manager, hired on and wondering how to turn a mostly amorphous vision for a facility into drawings and either a new building or a renovation of an existing space. Some discussion of the project’s program, what the facility’s intended to do, and its space requirements, budget and goals — both operational and initial capital needs, as well as potential cash flow — will quickly reveal how realistic (or unrealistic) the concept is. These calls come often. Sometimes there is a second or even third call. Some of these turn into real projects. It’s all part of the life of an acoustical consulting firm.
