  • Track 20: 100 Hz @ -10 dBFS
  • Track 21: 400 Hz @ -10 dBFS
  • Track 22: 1 kHz @ -10 dBFS
  • Track 23: 4 kHz @ -10 dBFS
  • Track 24: 8 kHz @ -10 dBFS

Tracks 25-30 are used to obtain 15 dB of gain overlap

  • Track 25: 40 Hz @ -15 dBFS
  • Track 26: 100 Hz @ -15 dBFS
  • Track 27: 400 Hz @ -15 dBFS
  • Track 28: 1 kHz @ -15 dBFS
  • Track 29: 4 kHz @ -15 dBFS
  • Track 30: 8 kHz @ -15 dBFS

Tracks 31-35 are the same as tracks 2-6. However, the levels of these tracks have been adjusted to compensate for the loudness increase

  • Track 31: Reference track with 0 dB gain overlap
  • Track 32: 5 dB of gain overlap w/recording level lowered 4.9dB
  • Track 33: 10 dB of gain overlap w/recording level lowered 9.4 dB
  • Track 34: 15 dB of gain overlap w/recording level lowered 13.3 dB
  • Track 35: 20 dB of gain overlap w/recording level lowered 16.2 dB

Excellent Tuning Tool

September 18, 2013

This CD is essential for fine tuning a high end car audio system. Directions are printed on inner jacket and are very easy to undetstand. I wouldn't use any other brand car audio set up disks then these.

Its a good disc to tune your system, but I rarely use it. I highly recommend the DD-1 but if you don't have that kind of money this is still a good choice.

great test cd

July 15, 2012

Has a couple tracks with music, so you can hear what some instrumental music sounds like, and it has several test tones that you can set gain with either by ear or with the use of an oscilloscope for precise tuning.

AWESOME BUY!!!!!!

April 26, 2012

The Autosound cds are a must for car audio. I have used them to tune my system, and now it rocks! There are many different tests on these cds. So, if you have a rocking system that needs tuned, Sonic Electronix has what you need.

autosound test cd (ultimate amplifier level setting cd)

January 15, 2012

If you wish to set your gains using an oscilliscope this is the cd for you. I have set the gains of several car audio systems using this cd and have noticed an improvement in sound quality. Using your ears will get you close this cd in combination whith an oscilliscope will get you bang on the money. Good stuff.
