Description


General Features
  • The Ultimate Amplifier Level Setting Disc, for Critical Evaluation of Audio Components
  • The ultimate test disc for determining the audible level of distortion in an audio system
  • Uses specialized tracks to set up your system for maximum sound and minimum system hiss
  • No special equipment is needed
  • The tracks will indicate the specific amount of gain overlap (clipping), average distortion, and the relative loudness present in your system
  • Other tracks on cd#104 will permit optimal component adjustments of the signal level to maintain optimal system performance
  • Also available in 5 Disc Set
  • Authorized Internet Dealer
  • 30 Day Manufacturer's Warranty
Specifications:

Tracks 2-6 demonstrate the subjective increase in loudness that can be obtained by providing a specified amount of gain overlapping at the amplifier of an audio system.

  • Track 2: Demonstrates 0 dB of gain overlap
  • Track 3: Demonstrates 5 dB of gain overlap
  • Track 4: Demonstrates 10 dB of gain overlap
  • Track 5: Demonstrates 15 dB of gain overlap
  • Track 6: Demonstrates 20 dB of gain overlap

Tracks 7-12 are used for setting the max level (clipping threshold) of electronic components

  • Track 7: 50 Hz @ 0dBFS useful for adjusting subwoofer crossover)
  • Track 8: 100Hz @ 0dBFS useful for setting midbass of an electronic crossover
  • Track 9: 400Hz @ 0dBFS useful for x-over setting at this frequency
  • Track 10: 1kHz @ 0dBFS used to set x-over midrange output
  • Track 11: 4kHz @ 0dBFS useful to set tweeter output of an electronic crossover
  • Track 12: 8kHz @ 0dBFS useful to set tweeter output of an electronic crossover

Tracks 13-18 are used to obtain 5 dB of gain overlap

  • Track 13: 40 Hz @ -5 dBFS
  • Track 14: 100 Hz @ -5 dBFS
  • Track 15: 400 Hz @ -5 dBFS
  • Track 16: 1 kHz @ -5 dBFS
  • Track 17: 4 kHz @ -5 dBFS
  • Track 18: 8 kHz @ -5 dBFS

Tracks 19-24 are used to obtain 10 dB of gain overlap

  • Track 19: 40 Hz @ -10 dBFS
  • 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

AWESOME BUY!!!!!!

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.

Excellent Tuning Tool

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.

AutoSound 2000 CD-104

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.

autosound test cd (ultimate amplifier level setting cd)

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.

great test cd

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.

Great for tuning a new system!

This was the first time I tuned the new sound system and amplifier in my car, and this product really helped me do it right on the first try.
