In this article, we will explain how to use the Denon Audio Technical CD to test your audio system and improve your listening experience. We will also explain what each track on the CD does and how to interpret the results. We will also provide some tips and precautions for using the CD safely and effectively.

What You Need

To use the Denon Audio Technical CD, you will need the following equipment:

  • A CD player that can play standard CDs and has a digital output (optical or coaxial).

  • A digital-to-analog converter (DAC) that can accept the digital output from the CD player and convert it to analog signals.

  • An amplifier that can amplify the analog signals from the DAC and drive your speakers or headphones.

  • A pair of speakers or headphones that can reproduce the full range of frequencies from 20 Hz to 20 kHz.

  • A sound level meter (SLM) that can measure the sound pressure level (SPL) in decibels (dB) at your listening position.

  • A frequency counter that can measure the frequency of the test signals in hertz (Hz).

  • A distortion meter that can measure the total harmonic distortion (THD) of the test signals in percentage (%).

  • A phase meter that can measure the phase difference between the left and right channels in degrees ().

  • A stopwatch or a timer that can measure the duration of the test signals in seconds (s).

You may not need all of these equipment depending on what aspects of your audio system you want to test. However, it is recommended that you have at least a CD player, a DAC, an amplifier, a pair of speakers or headphones, and a sound level meter.

How to Use the CD

The Denon Audio Technical CD is divided into four sections: announcement for basic checks, source material for listening tests, test signals for basic checks, and various measurement signals. Each section has a different purpose and contains different tracks. Here is how to use each section:

Announcement for Basic Checks

This section contains two tracks: one in English and one in Japanese. They announce the name of the CD, its purpose, and some basic instructions for using it. They also warn you not to play the CD at high volume or damage your speakers. You should listen to this section before using any other section of the CD. It will help you familiarize yourself with the CD and prepare your audio system for testing.

Source Material for Listening Tests

This section contains nine tracks of different musical genres: orchestra, concerto, chamber music, piano, organ, jazz, rock, announcement English, and announcement Japanese. They are recorded with emphasis encoding, which is a technique that boosts high frequencies during recording and reduces them during playback. This reduces noise and improves sound quality.

You should use this section to test your audio systems ability to reproduce music with clarity, accuracy, dynamics, and realism. You should listen to each track carefully and compare them with other recordings of similar music. You should also pay attention to how well your audio system handles different instruments, vocals, soundstage, imaging, and ambience.

Test Signals for Basic Checks

This section contains 18 tracks of different test signals: sine waves, square waves, tone bursts c481cea774
