In a multi-channel amplifier, the connection of two channels to drive a single load. The input signal is split, and then the phase of one of the signals is inverted. The non-inverted signal is sent to the left amplifier and the inverted signal is sent to the right amplifier (L+R-). The load is connected between the two outputs so it receives twice the voltage at a given input level. The resultant power is much greater than the two 4-ohm channels combined.

Electrical impedance, or simply impedance, describes a measure of opposition to alternating current (AC). Electrical impedance extends the concept of resistance to AC circuits, describing not only the relative amplitudes of the voltage and current, but also the relative phases. When the circuit is driven with direct current (DC) there is no distinction between impedance and resistance; the latter can be thought of as impedance with zero phase angle.

A measure of the proportion of electrical energy fed to a loudspeaker that is turned into acoustic energy. Most loudspeakers are very low efficiency transducers (typically around 5 per cent). Only horn loudspeakers manage a much higher efficiency (sometimes around 30 per cent).

Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and commutator-type electric machines of the dynamo type. Direct current may flow in a conductor such as a wire, but can also be through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric charge flow in a constant direction, distinguishing it from alternating current (AC). A term formerly used for direct current was Galvanic current.

Generally, an amplifier is any device that will convert one signal (often with a very small amount of energy, a few milliwatts) into another signal (often with a larger amount of energy e.g. several hundred watts). A power amplifier converts a low-power signal from a pre-amplifier into a high-power signal (tens to hundreds of watts) needed to drive a loudspeaker.

    The unit by which resistance to electrical current is measured. From Ohm's Law (Current=Voltage/Resistance, or in other words, Current=Voltage/Ohms), a mathematical expression of the relationship between these three elements. It is also symbolized by the Greek capital letter omega (Ω).

    Stereophonic sound, commonly called stereo, is the reproduction of sound using two or more independent audio channels through a symmetrical configuration of loudspeakers in such a way as to create the impression of sound heard from various directions, as in natural hearing. It is often contrasted with monophonic, or "mono" sound, where audio is in the form of one channel, often centered in the sound field (analogous to a visual field).

    Literally, bandwidth is a frequency span. Beyond that definition, its meaning will depend somewhat on context. For example, the bandwidth of a bandpass filter is the upper cutoff frequency minus the lower cutoff frequency (cutoff frequency being the filter's -3 dB point). The audio bandwidth is generally given as 20 Hz to 20,000 Hz, although there are harmonic components of audio that extend far above the 20k point. In most situations where bandwidth is given as an audio spec, the wider the frequency range the better. Be sure that when comparing bandwidth on different devices, that the same spec is being expressed. For example, some effects devices cite their bandwidth spec based on the dry, or unprocessed signal, while others give the bandwidth of the actual processed sound. These difference between these two specs (both listed as "bandwidth") can be substantial.

  • Definition ofBalanced:] body=[
    An audio line comprising three conductors: two carrying signal and a ground (shield) wire, in which one of the signal wires carries the sound and the other carries an inverted copy. When the signal reaches the destination, the inverted copy is flipped and added to the original. Any noise that has been induced into the signal is also inverted. When this is combined with the "uninverted" noise, it cancels it out. Balanced lines thus are less susceptible to hum and can carry audio signals over longer distances. Balanced audio lines typically use 3-pin XLR or 1/4-inch tip-ring-sleeve, phone connectors.

  • Definition ofSpeakon:] body=[
    The Speakon is a type of cable connector, originally manufactured by Neutrik, mostly used in professional audio systems for connecting loudspeakers to amplifiers. The same manufacturer produces another connector dubbed PowerCon, which is designed to carry mains power rather than audio signal. The audio and power designs cannot connect to each other.

    A Speakon connector is designed with a locking system that may be designed for soldered or screw-type connections. Line connectors (female) mate with (male) panel connectors and typically a cable will have identical connectors at both ends. If it is needed to join cables, a coupler can be used (which essentially consists of two panel connectors mounted on the ends of a plastic tube). Recently the manufacturer has introduced a new series called STX which includes also male line connectors and female panel connectors (in the four-pole and eight-pole version only).

    A binding post is a connector commonly used on electronic test equipment to terminate (attach) a single wire or test lead. They are also found on loudspeakers and audio amplifiers as well as other electrical equipment. Commonly designed in a style called five-way or universal, such binding posts allow the connection of several different types of connections including Banana Plugs, Pin Connectors, Bare Wire and Lug Terminals.
