Quadrophonia - Find The Time (Part 1) (CD)


To transmit four individual audio signals in a stereo-compatible manner, there must be four simultaneous linear equations to reproduce the original four audio signals at the output. Quadrophonia - Find The Time (Part 1) (CD) systems used matrix decoding technology to recover four channels from the two channels recorded on the record.

Matrix systems can have a significant level of channel independence but not full channel separation. Matrix quadraphonic recordings can be played in two channels on conventional stereo record players. There are varying levels of stereo and mono compatibility in these systems. The term compatible indicates that:. This process could not be accomplished without some information loss. That is to say, the four channels produced at the final stage were not truly identical to those with which the process had begun.

In order for the effect to work as intended a recording engineer needed to be specially trained for working in each of these formats. Special mixing rules for matrix recording minimize the technological limitations inherent in matrix formats and mask or eliminate undesired side effects. A so-called matrix format, it utilized four sound channels which were "encoded" into two stereo album tracks.

These were then "decoded" into the original four sound channels. But with poor decode performance, these systems failed to match the accuracy or channel independence of later matrix formats.

The original systems DY and EV-4 suffered from low front left-right separation around 12 dB and a poor rear left-right separation of 2 dB. The decoders were designed more to give an effect rather than accurate decoding, which was mainly due to limitations in both systems.

Since both systems were very closely related mathematically, users only needed one decoder of either system to playback albums of both systems. Improved systems based on Peter Scheiber 's work on utilizing degree phase-shift circuitry came later, namely the QS and SQ systems. The first of these, known as QS, was developed by Sansui Electric. A so-called matrix format, it utilized 4 sound channels, which were "encoded" into two stereo album tracks.

Both SQ and QS had significant support from major record companies and hardware manufacturers during the s. They also achieved notable sales and market penetration. Unfortunately, due to the similarities in name and technology these could easily be confused by Quadrophonia - Find The Time (Part 1) (CD) public. Discrete reproduction describes a quadraphonic system in which all four channels are fully independent of each other. As its name suggests, with discrete formats the original four audio channels are passed through a four-channel transmission medium and presented to a four-channel reproduction system and fed to four speakers.

This is defined as a 4—4—4 system. Discrete phonograph systems use a specialized demodulator to decode four fully independent sound channels. This allowed for full channel separation. Such systems could be prone to reduced record life.

However, more durable vinyl formulations were quickly developed to work around this problem and nearly all discrete LPs use special vinyl. When discrete quadraphonic LPs are played on conventional stereo record Quadrophonia - Find The Time (Part 1) (CD) the entire music program can be heard in stereo.

This quadraphonic format was first marketed in the United States in May A fully discrete system, it eschewed matrix technologies in favor of a more sophisticated method. CD-4 also adds 2 additional "difference" audio channels to the main channels. The difference signals are encoded in ultrasonic carrier frequencies in the range of 30 kHz, which is above Quadrophonia - Find The Time (Part 1) (CD) audible range.

CD-4 requires a specialized phono cartridge with a "Shibata" stylus to read these additional high frequencies. The combined signals are then sent to a special demodulator for 4 channel decoding. The demodulator converts the ultrasonic signals back into the audible range and uses the difference channels to separate rear audio information from the main channels.

These are different mixes than those that appear on the album as they were remixed in by John Entwistle. The most notable difference is the track " The Real Me " used for the title sequence of the film which features a different bass track, more prominent vocals and a more definite ending, which was part of the original recording but faded out on the previous mix.

The Quadrophonia - Find The Time (Part 1) (CD) two songs marked Kenney Jones 's first on-record appearance with the Who after taking over on drums for the late Keith Moon.

The album keeps the Who tracks in the same order as the original double album Quadrophonia - Find The Time (Part 1) (CD) begins with the two High Numbers tracks.

A version of the album was released on CD in as Music from the Soundtrack of the Who Film Quadrophenia restoring the track listing to its original configuration, and adding "I'm The Face" to the running order.
