Jose Feliciano with two MD 421 microphones (for vocals and guitar) in 1970. With a diaphragm diameter of 27 millimeters (1.1 in), the MD 421 is classified as a large-diaphragm microphone. Its wide frequency response (30–17,000 Hz ± 3 dB) exceeded the former Hi-Fi standard and came close to the performance of condenser microphones.
A sound engineer at the controls of a SSL9000J mixer. Most, but not all, audio mixers can use monaural signals to produce simulated stereo sound through panning. provide phantom power required by condenser microphones. Some mixers can add onboard external effect units (reverb, echo, delay). Mixers with onboard digital effects typically offer a ...
Electret microphones require no polarizing voltage unlike other condenser microphones, but normally contain an integrated preamplifier which requires a small amount of power (often incorrectly called polarizing power or bias). This preamp is frequently phantom powered in sound reinforcement and studio applications. Other types include a 1.5 V ...
Designing and maintaining systems and processes using condensers requires that the heat of the entering vapor never overwhelm the ability of the chosen condenser and cooling mechanism; as well, the thermal gradients and material flows established are critical aspects, and as processes scale from laboratory to pilot plant and beyond, the design ...
Liebig condenser. The Liebig condenser (/ ˈ l iː b ɪ ɡ /, LEE-big) [1] or straight condenser is a piece of laboratory equipment, specifically a condenser consisting of a straight glass tube surrounded by a water jacket. In typical laboratory operation, such as distillation, the condenser is clamped to a retort stand in vertical
The condenser microphone, invented at Western Electric in 1916 by E. C. Wente, [22] is also called a capacitor microphone or electrostatic microphone—capacitors were historically called condensers. The diaphragm acts as one plate of a capacitor, and audio vibrations produce changes in the distance between the plates.
Microphones can be thought of as speakers in reverse. The sound waves strike the thin diaphragm, causing it to vibrate. [1] Microphone diaphragms, unlike speaker diaphragms, tend to be thin and flexible, since they need to absorb as much sound as possible. In a condenser microphone, the diaphragm is placed in front of a plate and is charged. [2]
The U47 was the first condenser microphone switchable between cardioid and omni-directional pick-up patterns. It incorporated the highly successful 12- micron -thick M7 capsule and VF-14 tube amplifier, which was a metal-clad pre-World War II pentode changed to work as a triode .
