Blaupunkt
Blaupunkt GmbH () was a German manufacturer, producing mostly car-audio gear and other electronic equipment. Owned by Robert Bosch GmbH from 1933 until 1 March 2009, it was sold to Aurelius AG of Germany. It filed for bankruptcy in late 2015 with liquidation proceedings completed in early 2016. The brand, now managed by GIP Development SARL of Luxembourg, is licensed for use by various product groups worldwide such as Air fryers. History Founded in 1924 in Berlin as "Ideal," the company was acquired by Robert Bosch AG in 1933. In 1938 it changed its name to "Blaupunkt", German for "blue point" or "blue dot", after the blue dot painted onto its headphones that had passed quality control. After World War II, Blaupunkt moved its headquarters and production to Hildesheim. Blaupunkt took over a former Philips/ Grundig factory in Portugal to produce automotive head units. It is still owned and operated by Bosch, used exclusively to make OEM units for car manufacturers and 24V ...

Car Audio
Vehicle audio is equipment installed in a car or other vehicle to provide in-car entertainment and information for the occupants. Such systems are popularly known as car stereos. Until the 1950s, it consisted of a simple AM radio. Additions since then have included FM radio (1952), 8-track tape players, Cassette decks, record players, CD players, DVD players, Blu-ray players, navigation systems, Bluetooth telephone integration and audio streaming, and smartphone controllers like CarPlay and Android Auto. Once controlled from the dashboard with a few buttons, they can be controlled by steering wheel controls and voice commands. Initially implemented for listening to music and radio, vehicle audio is now part of car telematics, telecommunications, in-vehicle security, handsfree calling, navigation, and remote diagnostics systems. The same loudspeakers may also be used to minimize road and engine noise with active noise control, or they may be used to augment engine sounds ...

Autofahrer-Rundfunk-Informationssystem
Autofahrer-Rundfunk-Informationssystem (ARI, German for: Automotive-Driver's-Broadcasting-Information) was a system for indicating the presence of traffic information in FM broadcasts used by the German ARD network of FM radio stations from 1974. Developed jointly by IRT and Blaupunkt, it indicated the presence of traffic announcements through manipulation of the 57 kHz subcarrier of the station's FM signal. ARI was rendered obsolete by the more modern Radio Data System and the ARD stopped broadcasting ARI signals on March 1, 2005. Functionality description SK signal The SK signal is actually the 57 kHz subcarrier that is transmitted by the ARI-compliant FM station for this functionality. This frequency, like the RDS subcarrier frequency is chosen because it is the third harmonic of the 19 kHz pilot tone used in the FM-stereo transmission standard. An easy way to understand that is that this frequency is the 19 kHz pilot tone multiplied by 3. An ARI-equip ...

Radio Data System
Radio Data System (RDS) is a communications protocol standard for embedding small amounts of digital information in conventional FM broadcasting, FM radio broadcasts. RDS standardizes several types of information transmitted, including time, station identification and program information. The standard began as a project of the European Broadcasting Union (EBU), but has since become an international standard of the International Electrotechnical Commission (IEC). Radio Broadcast Data System (RBDS) is the official name used for the U.S. version of RDS. The two standards are only slightly different, with receivers able to work with either system with only minor inconsistencies in the displayed data. Both versions carry data at 1,187.5 bits per second (about 1.2kbit/s) on a 57 kHz subcarrier, so there are exactly 48 cycles of subcarrier during every data bit. The RBDS/RDS subcarrier was set to the third harmonic of the 19 kHz FM stereo#Stereo FM, FM stereo pilot tone to mi ...

CD Player
A CD player is an electronic device that plays audio compact discs, which are a digital audio, digital optical disc data storage format. CD players were first sold to consumers in 1982. CDs typically contain recordings of audio material such as music or audiobooks. CD players may be part of home stereo systems, car audio systems, personal computers, or portable CD players such as CD boomboxes. Most CD players produce an output signal via a headphone jack or RCA jacks. To use a CD player in a home stereo system, the user connects an RCA cable from the RCA jacks to a hi-fi (or other power amplifier, amplifier) and loudspeakers for listening to music. To listen to music using a CD player with a headphone output jack, the user plugs headphones or earphones into the headphone jack. Modern units can play audio formats other than the original CD PCM audio coding, such as MP3, Advanced Audio Coding, AAC and Windows Media Audio, WMA.

Audiophile
An audiophile (from + ) is a person who is enthusiastic about high-fidelity sound reproduction. The audiophile seeks to achieve high sound quality in the audio reproduction of recorded music, typically in a quiet listening space in a room with good acoustics. Audiophile values may be applied at all stages of music reproduction—the initial audio recording, the production process, the storage of sound data, and the playback (usually in a home setting). In general, the values of an audiophile are seen to be antithetical to the growing popularity of more convenient but lower-quality music, especially lossy digital file types like MP3, lower-definition music streaming services, laptop or cell phone speakers, and low-cost headphones. The term '' high-end audio'' refers to playback equipment used by audiophiles, which may be bought at specialist shops and websites. High-end components include turntables, digital-to-analog converters, equalization devices, preamplifiers and ...

Audio Power
Audio power is the electrical power transferred from an audio amplifier to a loudspeaker, measured in watts. The electrical power delivered to the loudspeaker, together with the speaker's efficiency, determines the sound power generated (with the rest of the electrical power being converted to heat). Amplifiers are limited in the electrical power they can output, while loudspeakers are limited in the electrical power they can convert to sound power without being damaged or distorting the audio signal. These limits, or power ratings, are important to consumers in finding compatible products and comparing competitors. Power handling In audio electronics, there are several methods of measuring power output (for such things as amplifiers) and power handling capacity (for such things as loudspeakers). Amplifiers Amplifier output power is limited by voltage, current, and temperature: * Voltage: The amp's power supply voltage limits the maximum amplitude of the waveform it can o ...
