Description: SOUND CHECK 2 is the definitive audio test disc. Created in association with renowned record producer, engineer and musician Alan Parsons, it is available as a single CD or in a double CD case with built-in microphone and sound level meter, calibrated from -15dB to +12dB. When used in conjunction with its third octave tracks, SOUND CHECK 2 forms an instant system response analyser.
It contains 99 tracks of practical material compiled as a result of careful research and investigation into the needs of studio engineers, audio technicians, serious audiophiles, record producers and musicians. The disc has been designed not only to help assess the technical performance of a wide range of sound recording and reproduction equipment, but also to offer the very best available musical, vocal and effects sources for experimentation and demonstration.
The levels indicated on SOUND CHECK 2 refer to 0dB FS (Full Scale), the theoretical maximum level obtainable on digital recordings. Analogue equipment can be calibrated to read 0VU at the sine wave reference tone on this disc which is recorded at û14dB FS. Digital meters should indicate this level. There are no rigid standards regarding digital/analogue operating levels, however you can easily choose a higher or lower operating level. For example, if analogue VU meters are lined up to +2VU, then 0VU will represent û16dB FS.
By selecting individual tracks on your CD player while the disc is running, the announcements preceding test signals can be eliminated. This is especially useful for extended play of one track, when used in conjunction with the Store and Repeat or Continuous Play functions found on most CD players.
