Gold CD Test & Burn-In CD

Test & Burn-In CD (24K Gold CD, HDCD)

The test and burn-in CD offered by XLO Kabel and Reference Recordings is a valuable tool for the correct installation and cabling of your music system. The burn-in and demagnetizing tracks help you get everything from your system. Using examples from the Reference Recordings catalog, you learn not only about the correct phase position, but also about correct dynamics and miking.

  1. Channel identification - the left and right channels are correctly connected
  2. Voice in phase - the voice must be in the middle between the loudspeakers
  3. Voice in antiphase - the voice seems to stand completely detached in space and has no spatial representation
  4. Clapping - this repeated clapping sound is used by sound engineers to familiarize themselves with the sound conditions of the listening room. You can wonder the reverberation of the room at any position. Often, acoustic specialists are clapping through spaces to do just that. However, since each human clapper is slightly different and the clapping self has an acoustic influence, this track is more suitable.
  5. 315 Hz Test tone - this tone is used to determine balance differences in the electronics. A multimeter connected at the outputs of the system can display wonderful channel differences in the level.
  6. Prof. Johnson demonstrates space acoustics - a multimicrophone installation in a large studio is used for demonstrating spatial representation. Prof. Johnson walks around the hall and can be heard acoustically by his voice and the striking instruments. He also gives an example of a miking error, as it often occurs.
  7. Demagnetization sweep - is used to remove magnetic charges within all components of a hi-fi system. Should be carried out regularly. Please pay attention to the notes in the manual for use with cartridges!
  8. Bass frequency demagnetization fade - Since the frequency dividers in active as passive loudspeakers do not allow the high-frequency sounds in Track 7, this track is specifically designed for the demagnetization of the basses. Do not use this track to demagnetize pickups.
  9. Burn-in tones - all components of your music system have to be imported in order to achieve the best possible reproduction quality. This track speeds up the process enormously. Set the track to Repeat and let it run continuously. Play the track at normal volume. This will not damage your system. If you want to use only a HiFi component, but do not burn the speakers or feel disturbed by the sounds, you can put an 8 Ohm resistor with 10 watts of power between the ends of your speaker cables. These resistors are available for small money in electrometers and standard quality for this application. This track is not suitable for burning pickup systems. These must be retracted mechanically.
  10. Mono music piece in phase - the voice and all musicians should be in the middle between the speakers.
  11. A mono piece of music in the opposite phase - the voice and all the musicians should be completely undefined in the room and do not seem as if they come from the nothing and are represented over a wide width. The less their loudspeakers can be positioned, the better they form when the signal is in phase.
  12. Stereo in the wrong absolute phase - this track sounds good at the first listen, but whoever listens more intensely will find that the musical performance is not really real. The track is in the same phase for the left and the right, but overall in opposite phase. That is, when an air stream in the direction of the microphones went in the original, the reproducing speakers simulate a stream of air that is going away from the listener. The same signal is produced by measuring technology, but there are musicians who perceive the difference. If you do not hear it, do not worry, not every person perceives this difference.
  13. Stormy Weather - the track of the previous tracks in correct phase and full length. The singer Eileen Farrell had just celebrated her 70th birthday and you can hear the age of her voice wonderfully. The sense of space does not come from the reception room, but is artificially generated. Look for the position of the winghorn in the back of the stage.
  14. Shiny Stockings - Big Band Jazz with a big dynamo. The piece begins very quietly with a pianosolo and increases more and more. Finally, five trumpets, three trombones, five saxophones, acoustic bass and drums play. If your system can reproduce all this without smearing the instruments or surrendering before the dynamics capture, then you have done a lot of things right.
  15. Morton Gould is a big band and they have the possibility to listen to the wind instruments one by one. Recorded together with the brilliant acoustics of the Medinah Temple in Chicago.
  16. Janácek - Sinfonietta, "The Queen's Monastery" - This track comes from the first symphonic HDCD recorded in the Czech Republic. There are 26 violins and an equal number of larger stringed instruments. Includes many solos and especially the horns at 3:45 are interesting.
  17. Biebl - Ave Maria - Gigantic choral recording with 30 voices in the center and another 200 voices on the sides. The spatial representation extends beyond the loudspeakers on both sides. The recording was made in "Cathedrals Mode" of the customizable Meyerson Symphony Center in Dallas.
  18. Weinberger - Polka and Fugue - After a common polka, this show presents all instruments of a symphonic orchestra and also their position in the orchestral arrangement. With the use of the organ at 5:38, the orchestra continues to increase in the level, and the combination of organ and bass registers is a challenge for every installation. Most music systems will distort at high levels. Gently touch the limit of your system. Good luck.

The best sound is achieved by using L'Art du Son CD / DVD Conditioner before playing.
