Although MP3 players are becoming more and more popular, CDs are still the standard form of recording and distributing hard copies of music. In order for the CD to play at its optimum level, the CD player must be able to reproduce the sound at a high quality. Just like any other product, there are both good and bad models on the market. By learning rate CD players, you can effectively inform the public regarding what to buy.
Instructions
1. Position the CD player in an open room. Clear any objects or materials away from the CD player's speakers. Sit comfortably in a chair if you plan on listening using head phones.
2. Insert a CD that has a wide range of sounds. Record a mix CD that includes bassy hip-hop, high-end pop and midrange rock. This will test the range of the CD player's speakers.
3. Measure the amount of power. Turn the volume knob upward until you hear distortion. This is the peak output level of the stereo. A decent stereo will not distort as easily. Immediately reduce the volume if you begin to feel pain in your ears.
4. Evaluate the equalizer. Stereos with more settings and features give the user a much wider range of sound. Press the bass-boost option, and experiment with the different presets to test out its capabilities.
5. Note how often the CD skips. Most portable CD players will have an anti-skip switch around the edge. Jog or do something active to test this feature. If you have a bigger stereo, the CD should rarely skip at all.
