The (especially the rare 24K Gold disc) is widely considered one of the most valuable test CDs ever produced. It empowers owners of any system, from budget setups to high-end reference rigs, to take control of their listening experience.
The genius of the burn-in tracks is their . Unlike compressed pop music, these tones have zero dynamic compression. They force capacitors to form, driver surrounds to stretch, and solder joints to thermally cycle.
: The "Clap Track" helps identify room reflections and "problem spots" for acoustic treatment. Performance Optimization :
Unlike standard aluminum CDs, the special 24K Gold edition offers better reflectivity and increased longevity, ensuring that the test signals and musical tracks are read with maximum accuracy over time. The (especially the rare 24K Gold disc) is
These tracks are selected for their natural sound, depth, and spatial qualities, designed to test speaker imaging and transient response.
Before you can enjoy true stereophonic imaging, your speakers must be perfectly positioned and perfectly in phase. The test tracks on this album provide precise acoustic cues that allow you to align your system by ear, without needing expensive measurement microphones. Tracklist Analysis and Functionality
Various Artists (VA) / Roger Skoff & Keith O. Johnson Album Title: XLO/Reference Recordings Test & Burn-In CD Edition: Special 24K Gold Edition Release Year: 1995 Format: FLAC (Free Lossless Audio Codec) Unlike compressed pop music, these tones have zero
| Track | Title | Duration | Detailed Purpose & Use | |:---:|---|---|:---:| | 1 | | 0:30 | Verifies that the left and right speakers are connected to the correct amplifier channels. A voice announces "Left Channel" from the left speaker, and "Right Channel" from the right. | | 2 | Voice In-Phase | 0:11 | A test for correct speaker wiring. Roger Skoff's voice should be clearly focused at the center point between the two speakers. | | 3 | Voice Out-Of-Phase | 0:25 | The same voice but with one speaker's polarity reversed. The image should collapse, becoming diffuse, unfocused, and lacking bass. This is a critical tool for speaker placement; listening to this track, you can move your speakers until the voice has no discernible location. | | 4 | Clap Track | 0:59 | A recording of a hand clap. This is used to assess your room's acoustics, specifically to identify excessive echo, flutter echo, or uneven sound decay. | | 5 | 315 Hz Test Tone | 1:15 | A single-frequency tone. This track has multiple uses: it can be used with an SPL meter to balance channel levels, with a voltmeter to check amplifier output balance, and for identifying room modes and "comb filtering" effects. | | 6 | "Prof." Johnson Does Something Spatial | 4:19 | Keith O. Johnson provides a fascinating, narrated demonstration of soundstaging, imaging, and depth, moving around and using percussive instruments to illustrate how spatial cues are captured in a recording. | | 7 | Demagnetizing Sweep | 0:57 | A sweeping signal (40Hz to 19kHz) designed to demagnetize the metal parts in the signal path (cables, connectors, PCBs) of your entire system. | | 8 | Demagnetizing Fade | 1:00 | A continuation of the demagnetization process, focusing on lower frequencies. These two tracks can be played at a high volume (your normal listening level) and are said to immediately clean up the sound. | | 9 | System Burn-In | 15:00 | A specially designed signal meant to be played on loop for hours or even days to "burn in" new components, particularly speakers, by exercising their full frequency and dynamic range. |
The gold layer provides a more consistent and highly reflective surface for the CD player's optical laser, significantly reducing data read errors and digital jitter.
