    This article is provided by Bartlett Audio.   Condenser microphones need phantom power to operate their internal circuitry. Phantom power is supplied to the mic through its 2-conductor shielded cable. The power can be supplied either from a stand-alone device or from a mixing console (at each mic connector). The microphone receives power from, and sends audio to, the mixer along the same cable conductors. It’s called “phantom” because the power does not need a separate cable; it’s “hiding” in… View this story

    Portable loudspeakers are amazing in their versatility, able to serve as mains, fills, delays, stage monitors and much more, providing solutions for hundreds of applications in live sound reinforcement. These 2-way miracle workers usually include an 8-inch, 12-inch or 15-inch ported woofer and a compression driver on a horn or waveguide, with dispersion (6 dB-down points) commonly at 40 degrees (v) by 90 degrees (h) or 40 degrees (v) by 120 degrees (h). The primary purpose of this dispersion is… View this story

    This article is provided by Bartlett Audio.   Getting a little bored with the same old “tried-and-true” microphones and techniques? Let’s have some fun with fresh approaches that are off the beaten path. Vocals To create a differential (noise-canceling) mic, tape two identical omni mics together, one over the other, separated by a block of wood (Figure 1). Mix both mics at equal levels but with one mic switched in opposite polarity. Have the performer sing close to the top… View this story

    This article is provided by Bartlett Audio.   As audio professionals, the more we understand what’s under the hood of modern power amplifiers, the better we can make a wise buying decision. What are the main sections or parts of a power amp? Every power amplifier includes a power supply, an input stage, and an output stage. Most amps also have protection mechanisms; some have DSP, and a few have networking capability. Let’s explain each feature… Power Supply Basically, a… View this story

    This article is provided by Bartlett Audio.   As if by magic, cardioid microphones can pick up what they are aimed at, but reject sounds to the side and rear. For example, talk into a cardioid mic from all sides while listening to its output. Your reproduced voice will be loudest when you talk into the front of the mic and softest when you talk into the rear. Because they discriminate against sounds to the sides and rear, cardioid designs… View this story

    Bruce Bartlett 08/09/16 12:18 PM,
    This article is provided by Bartlett Audio.   Microphone choice and technique have a powerful affect on the amplified sound of a reinforcement system. The sound picked up might be “natural,” “boomy,” “thin,” “colored” and any other number of descriptive terms that are applied to a sonic signature. It’s usually most desirable to attain “natural” sound. But what does that mean? I define it as the tonal balance heard with our ears in front of a musical instrument, a few… View this story

    phantom power
    Bruce Bartlett 06/21/16 06:22 AM,
    This article is provided by Bartlett Audio.   Unsure about phantom power? Let’s clear up the mystery. Nearly all mixing consoles and audio interfaces provide phantom power at their microphone input connectors. Most condenser mics need phantom power to operate, so you simply plug the mic into the mixer to power it. But the ways we use and connect phantom power can make a big difference in how well those mics work. So what, exactly is phantom power, and how… View this story

    This article is provided by Bartlett Microphones.   Remote recording is exhilarating. Musicians, excited by the audience, often put on a stellar performance. Usually you only get one chance to get it recorded, and it must be done right. It’s on the edge, but by the end of the night, especially if everything has gone as planned – what a great feeling! Challenges abound. Monitors can feed back and/or leak into the vocal microphones, coloring the sound. Bass sound can… View this story

    This article is provided by Bartlett Microphones.   Nothing has more effect on the sound of your recordings than microphone technique. For example, which mic you choose—and where you place it—affect the recorded tone quality. That is, mic technique affects how much bass, midrange, and treble you hear in the monitored sound of a musical instrument. Mic choice and placement also affect how distant the instrument sounds in the recording, and how much background noise you pick up. This guide… View this story

    This article is provided by Bartlett Microphones.   Some time ago I decided I wanted to find out how the location of a microphone near a banjo affects the tone quality you hear. To make these tests scientific as well as subjective, I measured the spectrum of the banjo in several different mic locations. The spectrum of a musical instrument is its output vs. frequency. It affects the tonal balance or timbre. It is the relative levels of the fundamental… View this story
