Meaning of "interconnection" in the English dictionary
General liquid surface cleaners and disinfectants, as well as aerosol sprays, are OK to use on exterior surfaces. A clean, soft-bristle toothbrush can also be used to clean between the strands of grille wire if needed. Avoid liquid contact with the microphone diaphragm as damage may occur.
After surface cleaning, be certain to let the grille air-dry before use. If a deeper cleaning is desired and your microphone has a removable threaded-on grille, remove the grille and soak it including the inner foam components in hot soapy water containing your chosen detergent. Be certain to let the grille and foam components air-dry before use. The large selection of Electro-Voice microphone accessories includes removable external foam windscreens for your microphone model.
These foam windscreens can be washed in hot, soapy water containing your chosen detergent, rinsed and allowed to air dry before use. Owning more than one of these windscreens allows rotation between cleaning and use cycles, as well as providing clean windscreens for each of multiple users.
Due to the nature of how they are used, judicious care and hygiene practices are recommended when using any vocal microphone.

Are you getting ready to buy a new amp? Is your band booking some bigger venues and in need of new loudspeakers? Are you just starting out and have no idea what equipment you need?
As you look up equipment details, a lot of the terminology can be pretty confusing. What do all those specs mean? Is it different from a loudspeaker? Why is a watt power amp cheaper than a watt power amp? What's a balanced signal, and why does it matter? You just need to understand the terms that matter to you.
This quick-reference guide explains some basic audio terms and why they matter. A Column Array - Generally a single cabinet with the elements of the array oriented in a straight line to provide some level of directivity at a range of frequencies. A Constant Curvature Array - An array of multiple boxes, each at the same angle of seperation between each array element. A Line Array is a loudspeaker system made up of a number of loudspeaker elements joined in a line to create a single sound source.
The loudspeakers must be close enough together to send sound waves farther than individual loudspeakers, and with a more evenly distributed sound output pattern. A balanced signal allows for the use of long cables while reducing susceptibility to external noise.
Professional audio products support balanced signals. A typical balanced cable contains two identical wires, which are twisted together and then wrapped with a third conductor that acts as a shield. A continuous signal of a single frequency capable of being modulated by a second, data-carrying signal.
Audio distortion caused by pushing an amplifier to create a signal with more power than its source can produce i. The signal will cut off when it reaches maximum capacity, which produces clipping. Also called phase cancellation. A comb filter adds a delayed version of a signal to itself, causing interference.
Comb filtering can occur when two loudspeakers are playing the same signal at different distances from the listener. In an enclosed space, a listener hears a mixture of direct sound and reflected sound. Because the reflected sound takes a longer path, it sounds like a delayed version of the direct sound, which is called comb filtering.
Reducing the dynamic range of a signal for recording and then expanding it to its original value for reproduction or playback. A small specialized diaphragm transducer which generates the sound in a wave guide or horn. They are very high-efficient compared to cone radiating loudspeakers, typically used as midrange or high frequency drivers in high power sound reinforcement loudspeakers and public address systems.
An electrical circuit passive or active consisting of a combination of filters used to divide an audio frequency into segments suitable for individual loudspeaker use. Active crossovers split frequency bands prior to amplification of the audio signal. Passive crossovers split frequency bands after amplification of the audio signal, just before reaching the individual loudspeaker components. One cycle is the transition of a sine wave from 0 to positive crest down through 0 to the negative crst and back to 0.
One full cycle is shown in this graph. Cycles per Second refers to the number of times a full cycle is repeated in the period of one second. Cycles per Second is usually expressed as hertz Hz. One hertz is equal to one cycle per second. A logarithmic scale that is used to measure signal levels. Sound pressure level SPL can be measured in dB. Decibels unloaded; reference voltage for professional applications.
Decibel volts; reference voltage for consumer applications. An electronic circuit that delays the audio signal for a short period. Used to compensate for time differences of multiple signals and align them into a coherent signal, e. A device that enables a musical instrument to be connected directly to a mic- or line-level mixer input.
The alteration of the original shape or other characteristic of a sound wave which changes the sound. Distortion is usually unwanted, but it may be stylistically desirable for certain instruments, such as an electric guitar. The three principal types of intentional distortion effects are overdrive, distortion, and fuzz. The method of minimizing the effects of multipath delays that can create drop-outs of the RF signal. Frequency Response is given as the range of frequencies between the points at the upper and lower ends of the sounds spectrum, where the speaker response is 3 dB below the nominal output level.
This indicates that the system is starting to have a reduced output below this frequency. Frequency Range is given as the range of frequencies between the points at the upper and lower ends of the sound spectrum, where the speaker response is 10 dB below the nominal output level.
Anything below or above this frequency range should not be expected to be reproduced from the system. A frequency-dependent amplifier circuit designed to amplify, pass, or attenuate certain frequency ranges. A Low-Pass Filter allows frequencies below its cutoff to pass and progressively attenuates frequencies above the cutoff.
A High-Pass Filter allows frequencies above its cutoff to pass and progressively attenuates frequencies below the cutoff. Professional audio equipment should maintain a good technical ground and operate with a good safety ground.
The amount of resistance offered by an electronic circuit or device to the AC current that flows through it. A circuit that allows signals below a specified input power to pass unaffected while attenuating the peaks of stronger signals that exceed this input power.
A limiter is a compressor with a high ratio and, generally, a fast attack time. An electroacoustic transducer that produces sound in response to an electrical audio signal input. To reproduce a wide range of frequencies, most loudspeaker systems use more than one driver.
Individual drivers reproduce different frequency ranges. Condenser Microphone A microphone where a condenser capacitor is created by stretching a thin diaphragm in front of a metal disc the backplate. Condenser microphones require external voltage to operate, which is normally supplied in the form of phantom power from the microphone preamp or the mixing console. Dynamic Microphone A microphone design where a wire coil is attached to a small diaphragm. Sound pressure causes the coil to move in a magnetic field, thus creating electrical voltage proportional to the sound pressure.
Since dynamic microphones have a weaker signal than condenser mics, they must be placed relatively close to the audio source. Since the sound reaching the rear of the diaphragm travels slightly farther than the sound at the front, it is slightly out of phase.
The greater this phase difference, the greater the pressure difference and the greater the diaphragm movement. As the sound source moves off the diaphragm axis, this phase difference decreases due to decreasing path length difference.
This is what gives a directional microphone its directivity. Cardioid A type of microphone that has a heart-shaped polar, or directional, pattern. It is the most common unidirectional microphone in use because it effectively rejects sound from other directions.
Hyper-Cardioid A type of microphone with a tighter area of front sensitivity and a smaller lobe of rear sensitivity.
Super-Cardioid Similar to a hyper-cardioid microphone, except there is more front pickup and less rear pickup. In wireless systems, it is interference due to multiple arrivals of the same RF signal due to reflections off nearby objects. The difference in path lengths creates different arrival times, thus causing signal cancellation and degradation. A type of cable connector mostly used in professional audio systems for connecting loudspeakers to amplifiers.
Speakon connectors are a higher current-carrying alternative to other connectors for loudspeakers. NL4 is a type of Speakon connector that has four electrical connections.
The electrical output of the amplifier module based on a set of test parameters. There are many different kinds of power ratings for amplifiers and speakers, which can make comparisons difficult unless you identify the ratings that use the same test parameters.

Enhance Power Systems Stability
It was established by the Government of Quebec in from the expropriation of private firms. This was followed by massive investment in hydro-electric projects like the James Bay Project. Today, with 63 hydroelectric power stations , the combined output capacity is 37, megawatts. Its residential power rates are among the lowest in North America. In Quebec , advocates for the creation of a public hydroelectric utility protested against high costs, poor rural electrification , and the lack of French speakers in management positions in hydroelectricity companies. Duplessis's conservative reign, now known as the Grande Noirceur , ended when he died in office in

SAA semantic audio analysis The automatic extraction of meaning from audio and the means for representing it, typically as metadata. One sabin is the sound absorption of one square foot or one square meter — a metric sabin of a perfectly absorbing surface—such as an open window. The sound absorption of a wall or some other surface is the area of the surface, in square feet, multiplied by a coefficient that depends on the material of the surface and on the frequency of the sound. These coefficients are carefully measured and tabulated. The unit honors Wallace Sabine see below. Sabine used this unit, which he called the open window unit owu , as early as A Dictionary of Units of Measurement ].
