MTX Audio is an American consumer audio company headquartered in Phoenix, Arizona [1] that manufactures sound equipment for applications including car audio, home audio, marine audio and live sound products. They are best known for their car audio products and they specialize in subwoofers and subwoofer amplifiers. [2]
The heaviest production subwoofer intended for use in automobiles is the MTX Jackhammer by MTX Audio, which features a 22-inch (560 mm) diameter cone. The Jackhammer has been known to take upwards of 6000 watts sent to a dual voice coil moving within a 900-ounce (26 kg) strontium ferrite magnet.
Audio stereo power amplifier made by McIntosh The internal view of a Mission Cyrus One hi-fi integrated audio amplifier (1984) [1]. An audio power amplifier (or power amp) amplifies low-power electronic audio signals, such as the signal from a radio receiver or an electric guitar pickup, to a level that is high enough for driving loudspeakers or headphones.
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
Representative schematic of a paralleled amplifier configuration. A paralleled amplifier configuration uses multiple amplifiers in parallel, i.e., two or more amplifiers operating in-phase into a common load. In this mode the available output current is doubled but the output voltage remains the same. The output impedance of the pair is now halved.
Amplifier manufacturers soon realized that the tube was capable of being used at ratings above the recommended maximums, and guitar amplifiers with 400V on the plates of a pair of 6V6GTA claim to produce an output power of 20W RMS at 5%THD with 40W Peak Music Power, and with 490V on the plates, as much as 30 W RMS.
A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load. The term usually refers to a type of radio-frequency (RF) power amplifier , some of which have output power measured in kilowatts , and are used in amateur radio .
The voltage on a speaker wire depends on amplifier power; for a 100-watt-per-channel amplifier, the voltage will be about 30 volts RMS. At such voltage, a 1% loss will occur at 0.3 ohms or more of inductive reactance. Therefore, to keep audible (up to 20,000 Hz) losses below 1%, the total inductance in the cabling must be kept below about 2 μH.
