Minnesota Public Radio News
KNOW-FM (91.1 FM) is the flagship radio station of Minnesota Public Radio's news and information network, primarily broadcasting a talk radio format to the Minneapolis-St. Paul market. The frequency was the original home of KSJN, but the purchase of a commercial station at 99.5 MHz in 1991 allowed MPR to broadcast distinct talk radio and classical music services. KNOW-FM's studios are located in the MPR Broadcast Center on Cedar Street in downtown St. Paul, while its transmitter is located on the Telefarm Towers in Shoreview. History The KNOW intellectual unit dates from 1980, when WLOL (1330 AM) was purchased by MPR in 1980 and changed its call letters to KSJN-AM, a simulcast of its FM sister. MPR was already making plans to offer a two-channel network when it acquired the frequencies to do so, and bought the AM frequency as a stopgap. In 1989, KSJN-AM changed its call letters to KNOW and began airing an expanded lineup of NPR programming. Two years later, MPR bought 99.5 ...

Classical Music
Classical music generally refers to the art music of the Western world, considered to be distinct from Western folk music or popular music traditions. It is sometimes distinguished as Western classical music, as the term "classical music" also applies to non-Western art music. Classical music is often characterized by formality and complexity in its musical form and harmonic organization, particularly with the use of polyphony. Since at least the ninth century it has been primarily a written tradition, spawning a sophisticated notational system, as well as accompanying literature in analytical, critical, historiographical, musicological and philosophical practices. A foundational component of Western Culture, classical music is frequently seen from the perspective of individual or groups of composers, whose compositions, personalities and beliefs have fundamentally shaped its history. Rooted in the patronage of churches and royal courts in Western Europe, surviving earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Live From Here
''Live from Here'', formerly known as ''A Prairie Home Companion with Chris Thile'', is an American variety radio show known for its musical guests, tongue-in-cheek radio drama, and relaxed humor. Hosted by Chris Thile, it aired live on Saturday evenings. The show's initial home was the Fitzgerald Theater in St. Paul, Minnesota. In 2019, the show moved to The Town Hall (New York City), The Town Hall in New York City, where it remained until its cancellation the next year. The show was derived from the historic''A Prairie Home Companion, A Prairie Home Companion with Garrison Keillor'' (''APHC'') radio show.

HD Radio
HD Radio (HDR) is a trademark for an in-band on-channel (IBOC) digital radio broadcast technology. It generally simulcasts an existing analog radio station in digital format with less noise and with additional text information. HD Radio is used primarily by AM and FM radio stations in the United States, Canada, and Mexico, with a few implementations outside North America. The term "on channel" is a misnomer because the system actually broadcasts on the ordinarily unused channels adjacent to an existing radio station's allocation. This leaves the original analog signal intact, allowing enabled receivers to switch between digital and analog as required. In most FM implementations, from 96 to 128 kbps of capacity is available. High-fidelity audio requires only 48 kbps so there is ample capacity for additional channels, which HD Radio refers to as "multicasting". HD Radio is licensed so that the simulcast of the main channel is royalty-free. The company makes its money ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monaural
Monaural or monophonic sound reproduction (often shortened to mono) is sound intended to be heard as if it were emanating from one position. This contrasts with stereophonic sound or ''stereo'', which uses two separate audio channels to reproduce sound from two microphones on the right and left side, which is reproduced with two separate loudspeakers to give a sense of the direction of sound sources. In mono, only one loudspeaker is necessary, but, when played through multiple loudspeakers or headphones, identical signals are fed to each speaker, resulting in the perception of one-channel sound "imaging" in one sonic space between the speakers (provided that the speakers are set up in a proper symmetrical critical-listening placement). Monaural recordings, like stereo ones, typically use multiple microphones fed into multiple channels on a recording console, but each channel is " panned" to the center. In the final stage, the various center-panned signal paths are usually mixed d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereophonic Sound
Stereophonic sound, or more commonly stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural recording, Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such as broadcast radio, recorded music, television, video cameras, cinema, computer audio, and internet. Etymology The word ''stereophonic'' derives from the Greek language, Greek (''stereós'', "firm, solid") + (''phōnḗ'', "sound, tone, voice") and i ...

Quadraphonic
Quadraphonic (or quadrophonic and sometimes quadrasonic) sound – equivalent to what is now called 4.0 surround sound – uses four audio channels in which speakers are positioned at the four corners of a listening space. The system allows for the reproduction of sound signals that are (wholly or in part) independent of one another. Four channel quadraphonic surround sound can be used to recreate the highly realistic effect of a three-dimensional live concert hall experience in the home. It can also be used to enhance the listener experience beyond the directional limitations of ordinary two channel stereo sound. Quadraphonic audio was the earliest consumer product in surround sound. Since it was introduced to the public in the early 1970s many thousands of quadraphonic recordings have been made. Quadraphonic sound was a commercial failure when first introduced due to a variety of technical issues and format incompatibilities. Four channel audio formats can be more expensive to ...

WLOL (Defunct)
KSJN (99.5 FM, "YourClassical MPR") is the flagship station of Minnesota Public Radio's classical music network, serving the Twin Cities region. KSJN's studios are located at the MPR Broadcast Center on Cedar Street in downtown St. Paul, while its transmitter is located on the KMSP Tower in Shoreview. The 99.5 frequency was established as commercial radio station WLOL-FM in 1957; the station achieved its most success as a top-rated Top 40/CHR station during the 1980s. It was purchased by MPR in 1991. Background KSJN intellectual unit Saint John's University in Collegeville, near St. Cloud, built and began operating the first station in the network, KSJR-FM (90.1), in January 1967. By 1968, however, it was obvious that there weren't enough listeners in the immediate St. Cloud area for the station to be viable. KSJR nearly tripled its power in hopes of reaching the Twin Cities, but even then it only provided grade B coverage of Minneapolis and completely missed St. Paul. To so ...

Call Sign
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations onboard ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a Marconi station ...
