Loudness compensation, or simply loudness, is a setting found on some hi-fi equipment that increases the level of the high and low frequencies. [1] This is intended to be used while listening at low-volume levels, to compensate for the fact that as the loudness of audio decreases, the ear's lower sensitivity to extreme high and low frequencies ...
The 3220PE and 3225PE (PE being 'Power Envelope') are further improved versions of the 3020E and 3020i respectively, sharing circuit boards with the 3020 models, the main change being a different "dual voltage" transformer and improved power supply design. [20] [21] A 7175PE receiver model was also launched.
In the early and mid-1970s, for example, Ferguson made two-channel receivers with a built-in Hafler circuit. Philips had a similar circuit in their two-channel receivers. . Many receivers from middle price brands had such circuits, but often without a volume control for the rear chan
Marantz 2050L AM/FM stereo tuner (USA; 1978-1980) [1]. In electronics and radio, a tuner is a type of receiver subsystem that receives RF transmissions, such as AM or FM broadcasts, and converts the selected carrier frequency into a form suitable for further processing or output, such as to an amplifier or loudspeaker.
Inherently, any circuit above absolute zero generates some random noise that adds to the desired signals. In some cases, atmospheric noise is far greater than that produced in the receiver's own circuits, but in some designs, measures such as cryogenic cooling are applied to some stages of the receiver, to prevent signals from being obscured by ...
The term All American Five (abbreviated AA5) is a colloquial name for mass-produced, superheterodyne radio receivers that used five vacuum tubes in their design. These radio sets were designed to receive amplitude modulation (AM) broadcasts in the medium wave band, and were manufactured in the United States from the mid-1930s until the early 1960s.
