Demonstration

Sound Check 2 is the definitive audio test disc. Created in association with renowned record producer, engineer and musician Alan Parsons, it is available as a single CD or in a double CD case with built-in microphone and sound level meter, calibrated from -15dB to +12dB.When used in conjunction with its third octave tracks, SOUND CHECK 2 forms an instant system response analyser. It contains 99 tracks of practical material compiled as a result of careful research and investigation into the needs of studio engineers, audio technicians, serious audiophiles, record producers and musicians.The disc has been designed not only toтhelp assess the technical performance of a wide range of sound recording and reproduction equipment, but also to offer the very best available musical, vocal and effects sources for experimentation and demonstration.

"I produced the first Ultimate Demonstration Disc in 1995, and it went on to be a huge success. It caught on with audiophiles, especially those who read audiophile magazines like "Stereophile" and "The Absolute Sound," but didn't fully understand the lexicon of sound. Audiophile reviewers use words like "transparent" and "soundstage depth" all the time, but rarely describe exactly what the words mean. With the original and now this new UDD I spell out what to listen for on each tune. And since Chesky recordings are made by and for audiophiles the entire recording chain – the microphones, mic preamps, mixer, and analog-to-digital converter – is custom built to high-end standards.
