"Your Disc" A Unique and Simple to Use Cd that Takes some of the Mystery Out of your Audio System
Quantity: 1

General Features:
  • "Your Disc" A Unique and Simple to Use Cd that Takes some of the Mystery Out of your Audio System
  • Was created to demonstrate different characteristics and specifications of an audio system
  • Produced for the audio retailer as a sales training and technical tutorial
  • Intended to make it easier to demonstrate some of the more difficult to explain characteristics and specifications of an audio system
  • Also available in 5 Disc Set
  • Authorized Internet Dealer
  • 30 Day Manufacturer's Warranty
Reference Tracks:
  • Track 1: "Head Honcho", Clarity Recording
  • Track 2: "Infernal Dance", Sheffield Lab
  • Track 3: "Hummin' to Myself", Clarity Recording
  • Track 4: "Foggy Mountain Breakdown", Sheffield Lab

The Car Noise Demonstration contains actual recordings of cars traveling at 65MPH on a smooth stretch of highway with the windows rolled up and light traffic. Road noise poses a large challenge when it comes to obtaining great sound quality while you vehicle is in motion.

  • Track 5: This track is a level setting reference for tracks six through eleven
  • Track 6: This track is an actual recording of the background noise of a Lexus 400
  • Track 7: This track is identical to track 6 except that the test vehicle is a Ford Explorer
  • Track 8: This track is a musical track that plays without interruption for the first 10 seconds. After that, the noise that was recorded on Track 6 in the Lexus 400 is mixed in with the music. This demonstrates the effect on sound quality that is perceived by the listener under real world driving conditions
  • Track 9: This track is an actual recording of the background noise of a Ford Explorer and its background noise is mixed in
  • Track 10: This track is identical to track 8 (with the Lexus 400) except for the type of music has been changed to Classical due to its extreme difficulty in being reproduced accurately in car audio
  • Track 11: This track is identical to track 10 except that the test vehicle is the Ford Explorer

The Spectral Balance Demonstration shows the different frequencies in the musical spectrum when they are too loud or too soft. All the even tracks in this section contain a balanced recording, while the odd numbered tracks are unbalanced.

  • Track 12: This track is a normal, well-balanced recording
  • Track 13: This track should sound bass heavy and overly boomy
  • Track 14: This track is a normal, well-balanced recording
  • Track 15: This track should sound like it needs more bass
  • Track 16: This track is a normal, well-balanced recording
  • Track 17: This track should sound artificial and lack fullness
  • Track 18: This track is a normal, well-balanced recording
  • Track 19: This track should sound dull and lifeless
  • Track 20: This track is a normal, well-balanced recording
  • Track 21: This track should sound bright and tinny
  • Track 22: This track is a normal, well-balanced recording
  • Track 23: This track should sound dull and muffled

The Crossover Separation Demonstration plays the range of sounds that is audible to the human ear, which is usually between 20 and 20,000 Hz. It will play bass, midbass, midrange and highs(treble) so you can hear what each of those segments sound like in the typical 4-way system.

  • Track 24: Bass- this is the range that encompasses very large instruments such as cello, tubas and bass drums
  • Track 25: Mid-bass range - this is the range that generally contains male vocals, low guitars, and large wind instruments
  • Track 26: Midrange - is the foundation that the other ranges (bass, midbass and treble) hinge or adheres to. It contains vocals and the majority of musical instruments
  • Track 27: Treble - this is the range that contains flutes, triangles and smaller instruments as well as the harmonics of all the instruments that are necessary for natural, full sounding music

The Crossover Composition Demonstration shows how the different wavelengths of musical frequencies are intended to be played and combined at the output of the crossover to create a balanced and natural reproduction, beginning with the midrange.

  • Track 28: This track begins with the midrange foundation and contains only the frequencies from 400 Hz to 5 kHz
  • Track 29: This track takes track 28 and adds the midbass for a combined range of 80 Hz to 5 kHz
  • Track 30: This track takes track 29 and adds the high frequencies for a combined range of 80 Hz to 20 kHz
  • Track 31: This track takes track 30 and adds the lowest bass frequencies for a total spectral range of 20 Hz to 20 kHz

The System Noise demonstration intentionally slips noise into the music tracks at higher levels on each track. The first two seconds of each track contain the specified noise level so it can be heart without the music for easy comparison. On quality systems, the first few tracks should have noise levels that canít be herd while the last few tracks should have noticable noise levels. This dimonstration will help you understand the importance of noise levels and how they are herd in the real world.

  • Track 32: Noise @ -80dB below the level of the music
  • Track 33: -70 dB
  • Track 34: -60 dB
  • Track 35: -50 dB
  • Track 36: -40 dB
  • Track 37: -30 dB
  • Track 38: -20 dB

Distortion Demonstration (Tone): Using track 39 as your tonal reference, the following 4 tracks demonstrate increases in distortion using a pure tone.

  • Track 39: This track is the reference tone (with successive tracks that demonstrates increases in distortion)
  • Track 40: Same as track 39, except with 0.3% distortion
  • Track 41: Same as track 39, except with 1% distortion
  • Track 42: Same as track 39, except with 3% distortion
  • Track 43: Same as track 39, except with 10% distortion

Distortion Demonstration (Voice): Track 44 begins a demonstration that is identical to the previous one, except the test signal is a voice rather than a tone. This demonstrations characteristics of a voice combined with distortion make the distortion slightly more difficult to detect.

  • Track 44: This track is the reference voice
  • Track 45: Same as track 44, except with 1% distortion
  • Track 46: Same as track 44, except with 3% distortion
  • Track 47: Same as track 44, except with 10% distortion
  • Track 48: Same as track 44, except with 30% distortion

Distortion Demonstration (Music): Track 49 begins a demonstration that is identical to the previous two, except the test signal is music rather than a tone or a voice. This demonstrations characteristics of music combined with distortion make it even more difficult to detect than distortion combined with a voice or tone.

  • Track 49: This track is the reference song
  • Track 50: Same as track 49, except with 1% distortion
  • Track 51: Same as track 49, except with 3% distortion
  • Track 52: Same as track 49, except with 10% distortion
  • Track 53: Same as track 49, except with 30% distortion
