A preamplifier, also known as a preamp, is an electronic amplifier that converts a weak electrical signal into an output signal strong enough to be noise-tolerant and strong enough for further processing, or for sending to a power amplifier and a loudspeaker. [1] Without this, the final signal would be noisy or distorted.
A data link is a means of connecting one location to another for the purpose of transmitting and receiving digital information (data communication). It can also refer to a set of electronics assemblies, consisting of a transmitter and a receiver (two pieces of data terminal equipment ) and the interconnecting data telecommunication circuit .
A number of companies make combination preamplifier-DI units for electric bass, double bass, or for acoustic instruments which use piezoelectric pickups (e.g., a violin, acoustic guitar, mandolin, etc.). These units may be housed in a "stompbox" pedal format, in a small rackmount unit (often less than a full rack space), or in units designed to ...
Some older tape recorders, and equipment like receivers designed to connect to them, use a 5-pin DIN connector to connect left and right for record and playback with a single cable. Adapters between this connector and RCA connectors have used white and red for left and right channel recording, and blue (or sometimes black) and yellow for ...
In the case of UK BSkyB receivers, the LNB remains powered while in standby so that the receiver can receive firmware updates and Electronic Programme Guide updates. In the United States, the LNB connected to a Dish Network receiver remains powered so the system can receive software and firmware updates and guide information over the air at night.
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.
An audio/video receiver (AVR) or a stereo receiver is a consumer electronics component used in a home theater or hi-fi system. Its purpose is to receive audio and video signals from a number of sources, and to process them and provide power amplifiers to drive loudspeakers , and/or route the video to displays such as a television , monitor or ...
Circuit of a very simple preselector. For any one frequency, using a larger tuning coil results in a narrower bandwidth, i.e. greater rejection of out-of-tune signals.. A preselector is a name for an electronic device that connects between a radio antenna and a radio receiver.
