Unreferenced date December 2009 An integrated amplifier pre main amp is an electronic device containing an audio preamplifier and power amplifier in one unit, as opposed to separating the two. Most modern audio amplifiers are integrated and have several inputs for devices such as CD player s, DVD player s, and auxiliary sources. Integrated amplifiers commonly had dedicated inputs for Phonograph turntable s, Amplitude modulation AM FM broadcasting FM tuner radio tuner , and tape recorders cassette deck cassette or Reel to reel audio tape recording reel to reel back when those devices were more common. Except for the turntable, all of the inputs are line level , thus they are interchangeable. The turntable also uses RIAA equalization . In signal processing , an integrated amplifier is similar to an inverting amplifier , except that the feedback impedance includes a capacitor . However, due to non ideal properties of the operational amplifier , a resistor still needs to be added into the feedback path along with this capacitor.

Unreferenced date December 2009 Boutique amplifier is a catch all descriptor for any type of guitar amplifier that is typically hand built with the intention of being much better than the mass produced variety offered by large companies. In the majority of cases, this is reflected in the price. Sometimes they are clones of older designs, often with minor improvements in layout or circuit design. Sometimes they are new designs altogether. A common claim made is that they feature better parts than ever appeared in any commercially available amplifier, and use vacuum tubes as the primary means of processing sound. In all actuality most boutique designs use the same components used by the large manufacturers in bygone eras that were abandoned in favor of minimizing manufacturing costs. The term is probably derived from recent usage such as Boutique hotel , which relies on the understanding that Boutique indicates that an item is not a mass market, built to price point product. As a response to the many boutique builders, large companies have released reissues of their classic designs, touting their faithfulness to the original sound and the labor intensive building process. Terms like hand wired and Point to point construction point to point wiring abound. Regardless of whether an amplifier uses point to point or turret board or any other means of circuit board assembly, the term point to point has evidently been chosen as the default term to refer to all wiring methods. This has resulted in some confusion over their meaning. DEFAULTSORT Boutique Amplifier Category Instrument amplifiers ... more details

In electronics, a distribution amplifier or simply distribution amp, is a device that accepts a single input signal and provides this same signal to multiple Electrical isolation isolated outputs. These devices are important because they allow a signal to be distributed to multiple destinations without Ground loop electricity ground loops or signal degradation. They are used for a number of common engineering tasks, including multiple amplification, cable television , splitting monitor and front of house mixes, and tapping a signal prior to sending it through effects units to preserve a dry signal for later experimentation. Video distribution amplifier A Video Distribution Amplifier also known as a distribution amp or VDA is a type of electronic equipment that takes a video signal as an input, amplifies it, and outputs the amplified video signal to two or more outputs. It is primarily used to supply a single video signal to multiple pieces of video equipment. Function Video signals can suffer deterioration over relatively short cable distances. To compensate for that loss, a Video Distribution Amplifier VDA is used. A VDA adjusts the amplitude of a video signal to compensate for loss of signal in a video distribution system. Extending the distance of the signal of the video signal is the main purpose of the VDA. There are VDAs built for all video formats, NTSC , ATSC , QAM16, QAM32, QAM64, Composite Video and Component Video . Their construction and capabilities can be simple accept input signal, amplify, then output. Others can be more sophisticated that allow remote control from a control station, allow adjustment of the gain, equalization, and provide status of the input and output signals through Ethernet networks.
