American Marantz tradition also in PC4u Music configurations

Born in New York in 1911, graphic designer and amateur musician Saul Bernard Marantz was dissatisfied with the musical equipment available on the market and spent many hours constructing an amplifier that could reproduce his treasured collection of LP records. Marantz was founded in 1948, coinciding with the introduction of the monophonic LP (LP) by the Columbia Broadcasting System. In the 1970s, the company skillfully exploited American experience from the tube era in the use of transistors and applications with a wide range of technical innovations, such as stereo FM broadcasts, quadraphonic recording and Dolby-licensed noise reduction.

The 4400 model in the video is one of the flagship products

It even had built-in Dolby B circuitry. Such an amplifier is certainly an attractive trophy in the home for collectors of old hi-fi equipment, but rather impractical for a music lover. Half a century old potentiometers and switches need to be renovated. Capacitors have also aged, which means that the characteristics of this amplifier are now quite different from what is stated in the manufacturer's data sheet.

Now the FM tuner in the 4410 cannot provide the quality of the broadcast as from a stream that can be with Free Lossless Audio Codec and the studio sampling standard of 48 kHz, and after time it turns out that it was more optimal to invest in a traditional integrated amplifier 4140.

However, it was best to invest in separate components

The power amplifiers were made with great care and still perform well, although the capacitors have lost some of their properties.

The investment in a cassette recorder is now the least worthwhile, because there is no point in converting music copied from gramophone records even to MP3.

 The situation is slightly better with the 7700-2 reel-to-reel two-track tape recorder, but it did not become a hit. The more popular one might be the 7700-4 (four-track, 2 x stereo). It also doesn't hurt to remember that tapes recorded with 4 tracks cannot be played on better-class tape recorders with 2, but the other way around has never been a problem. 

Martantz was deeply involved in quadraphony, so he also proposed a suitable reel-to-reel tape recorder. However, tapes recorded on it cannot be played back on the 7700-2. In the 7700-4 they can only be played in stereo, but only from a reel that has been properly rewound. However, the one for quadraphony can play stereo recordings on 2- and 4-track tapes. There is only a slight drop in quality with 2-track recordings. The PC as a "tape recorder" is also universal and to an even greater extent.

The PC allows you to install the latest solutions so that it is like it used to be with Marantz equipment and removing it them when they are unnecessary

1st Reference 4 FM radio witch PC4uMusic configurations was as the name suggests for analog broadcasts. It could be built into a wooden case, as was done with the best hi-fi equipment. It could later be supplemented with DAB+ and various versions of DVB, and earlier even NICAM TV stereo. Now supports what the BBC calls Sound HD - 320 kbps stream with Advanced Audio Coding and 48 kHz sampling. 

The best quality of music playback from radio broadcasts is provided by the FLAC stream. More on this topic 48 kHz FLAC by Swedish Radio & EBU recordings

 

Digital signal can be converted to analog with 192 kHz 32 bit float oversampling for stereo, quadro and multi-channel 5.1 or 7.1 

 

The new speaker arrangement for surround sound and active studio monitors provide unique possibilities. Quadraphonic QS and SQ recordings can be played back quite reliably without a decoder. With CD-4 they must be analog decoded, but a non-traditional speaker arrangement for them is very beneficial in practice. Similarly, it is more practical for multi-channel recordings.
