Marantz is a company that develops and sells high-end audio products. [2] The company was founded in New York, but is now based in California. The first Marantz audio product was designed and built by Saul Marantz in his home in Kew Gardens, New York . [ 3 ]
The TRM-800 was a high-end solid state integrated stereo amplifier made in Japan, using NEC power transistors, by Nikko. It was the top-of-the-line model in the Nikko amplifier range of TRM's series; housed in a wooden walnut-finished cabinet and a brushed aluminum front panel, was introduced in 1975 [1] the same year as the Marantz 2235.
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. [ 1 ] [ 2 ] Most modern audio amplifiers are integrated and have several inputs for devices such as CD players , DVD players , and auxiliary sources.
D+M Group, formerly known as DMGlobal and D&M Holdings, is a Japanese corporation that owned several audio and video brands. It was formed in 2002 from the merger of Denon and Marantz.
The amplifier damping factor, which is the ratio of the nominal load impedance (driver voice coil) to amplifier output impedance, is adequate in either case for well-designed solid state amplifiers. Tube amplifiers have sufficiently higher output impedances that they normally included multi-tap output transformers to better match to the driver ...
Using the Smith chart, the normalised impedance may be obtained with appreciable accuracy by plotting the point representing the reflection coefficient treating the Smith chart as a polar diagram and then reading its value directly using the characteristic Smith chart scaling. This technique is a graphical alternative to substituting the values ...
