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 ...
An example of a typical high-end stereo preamplifier.. 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]
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 ...
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.
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.
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 ...
In a radio receiver circuit, the RF front end, short for radio frequency front end, is a generic term for all the circuitry between a receiver's antenna input up to and including the mixer stage. [1] It consists of all the components in the receiver that process the signal at the original incoming radio frequency (RF), before it is converted to ...
A crystal set receiver consisting of an antenna, a variable inductor, a cat's whisker, and a filter capacitor. A crystal receiver is very simple and can be easy to make or even improvise, for example, the foxhole radio. However, the crystal radio needs a strong RF signal and a long antenna to operate.
