Amplifier

JA-030, Johnson's RepTone series amplifier showcases style, power and performance. This versatile amplifier is an impressively loud 30 watts and is perfect as a practice amplifier as well as a performance amplifier for electric guitars, acoustic guitars and classical guitars. This amplifier comes with a 3-band EQ (3 separate controls for treble, middle, and bass), and volume, overdrive and master controls to give it a wider tonal variety that players seek and provide you with a total command of the sound output. It includes a high performance 8" high performance speaker with 30 watts output. With this kind of power, not only can this amplifier be used as a practice amp, it can also be used in band performances. In addition, it also comes with headphone jack and you can play late into the night without bothering anyone else. Both the input and headphone jacks are located in the front of the amplifier making them very easy to access. The amplifier uses high quality electronic components that delivers quality and performance. This amp is housed in a rugged dark green fabric covered cabinet for a tough look and feel. The fabric is scratch and dent resistant. A metal grill is used to provide the ultimate protection for the speaker. Features 30 Watts RMS output (RMS stands for "Root Mean Square", which is used for finding the average amount of power an amplifier can continuously produce. The RMS output in Watts is the measure of how powerful an amplifier is. The higher the wattage, the more powerful the amplifier is.) 8" high performance speaker delivers a lot of power - the bigger the speaker, the better sound quality output. 3-band EQ (3 separate controls for treble, middle, bass), volume control, overdrive control and master control give you uncompromised command of the sound output Deep cone placement for more prominent presence and tone Front power on/off switch and LED indicator for easy access Front input and headphone jacks for easy guitar cable access Standard 1/4" jacks for input, headphone, line out, and overdrive pedal. All jacks are made out of metal for dependability. Metal grill provides ultimate protection to the speaker Sturdy cabinet casing ensures amplifier's long term use Large handle makes carrying the amplifier easy Heavy duty power cable is more than 5 feet long allowing you to place the amplifier anywhere Rubber feet stations the amplifier solidly on the floor and prevents it from sliding Corner protectors shield amplifier from wear and tear This amplifier has been evaluated by the UL and has met all the applicable U.S. safety and performance standards. Weight: 25 lb Size: 15" Height, 14" Width, 9-1/2" Thickness Color: Dark Green

Crown IT 4000 Crown IT 4000 Description: The world has seen many good amplifiers, but few achieve greatness. What sets these elite few apart from all the others? The answer is simple: A careful synthesis of unrivaled sonic performance combined with rock-solid dependability. While the definition of a great amplifier may be simple, delivering on those requirements is not. This is what has always set Crown amplifiers apart from the others: Crown delivers. From the slightest nuances in the tremolo of a flute to the chest pounding bass of a rock 'n' roll kick drum to the harmonic rich vocals of a jazz singer, Crown delivers. Crown amplifiers are renowned for their ability to accurately amplify anything audio-with unmatched power and accuracy-night after night without fail. For decades, the formula for creating great amplifiers has been the same at Crown: An insightful combination of genetics, breakthrough technologies, craftsmanship, and passion. This formula, proven over and over, has produced a lineage of great amplifiers: DC-300, PSA-2, Micro-Tech® , Macro-Tech® , Studio Reference , K, and CTs: Each amplifier great in its time, and each raising the standard for high performance. Once again, this formula for greatness has delivered on its promise: I-Tech, the world's next great amplifier, and the pinnacle of Crown's 50-year history of innovation. Crown IT 4000 Features: 1 Class-I - Interleave Technology I-Tech's patented Interleave switch-mode design delivers a solid combination of high output power and a smaller, lighter weight package. Officially designated "Class-I," this break-through technology provides a clear advantage over conventional amplifier (Class-D) models by providing lower distortion, higher voltage, higher power, and greater reliability. 2 Industry's Highest Output Voltage Today's high-performance loudspeakers need additional voltage drive to really come alive. I-Tech features the highest output-voltage capability of any professional amplifier. 3 Regulated Switch-Mode Power Supply An all-new, ground-breaking power supply forms the heart of the I-Tech Series. Crown's regulated switch-mode power supply delivers full power regardless of mains voltage: from 120 to 277 volts, and from 50 to 60 Hz. 4 PFC (Power Factor Correction) Crown's innovative PFC technology allows I-Tech to draw current from the mains in a more controlled and efficient way than non-PFC amplifiers, providing massive amounts of power from a single 20 amp breaker. 5 Digital Audio Inputs (AES/EBU - CobraNetTM) I-Tech amplifiers feature digital audio inputs for exceptional audio quality. With AES/EBU inputs (standard) or optional CobraNet version, I-Tech provides your choice of today's most widely accepted digital audio formats. 6 Light Weight I-Tech packs a lot of power in a small but rugged, 2U package. Weighing in at less than 28 lbs. (12.7 kg), I-Tech delivers unmatched power for its weight class, far outpacing the competition in watts/po

Amplifier - An amplifier can be considered to be any device that uses a small amount of energy to control a larger amount, although the term today usually refers to an electronic amplifier. The relationship of the input to the output of an amplifier â€” usually expressed as a function of the input frequency â€” is called the transfer function of the amplifier, and the magnitude of the transfer function is termed the gain.

Current-feedback operational amplifier - The current feedback operational amplifier or CFB op-amp is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage as in a conventional voltage-feedback (VFB) operational amplifier. The CFB op-amp was invented by David Nelson at Comlinear Corporation, and first sold in 1982 as a hybrid amplifier, the CLC103.

Low-noise amplifier - The low noise amplifier (LNA) is a special type of electronic amplifier or amplifier used in communication systems to amplify very weak signals captured by an antenna. It is often located very close to the antenna.

Differential amplifier - A differential amplifier is a type of an electronic amplifier that multiplies the difference between two inputs by some constant factor (the differential gain). A differential amplifier is the input stage of most operational amplifiers, or op-amps.
