Philips is known to make products that are compatible with a wide variety of discs on the market. With this audio system you can enjoy music from CD, CD-R and CD-RW. CD-RW (CD-Rewritable-compatible) means that the audio system can play both CD-Recordable (CD-R) and CD-Rewritable (CD-RW) discs. CD-R discs can be recorded once and played back on any CD player. CD-RW discs, on the other hand, can be recorded and overwritten more than once and can only be played back on compatible CD players. The Shuffle/Repeat function means you never have to listen to your music in the same order again. Once you've loaded your music onto the player, you only need to select one of the two modes and each track will play in a different order. Enjoy a different and unique music experience every time you use the player. With Dynamic Bass Boost, you can emphasize the bass in your music at the touch of a button, regardless of the volume setting, for maximum listening pleasure. The lowest bass frequencies are usually lost at low volumes. To counteract this effect, Dynamic Bass Boost allows you to boost the bass levels so that an even sound is produced even at low volumes. Connect easily and enjoy all your music from portable devices and computers. Simply connect your device to the AUDIO input (3.5 mm) of your Philips system. For computers, the connection is usually made via the headset output. Once connected, you can enjoy your entire music collection directly through high-quality speakers. Philips simply delivers better sound. This system offers a 3 W RMS total output power. RMS stands for Root Mean Square and is a typical unit of measurement for audio power, or rather the electrical power transmitted from an audio amplifier to a loudspeaker and measured in watts. The amount of electrical power transferred to the speaker and the sensitivity of the speaker determine the sound power produced. The higher the wattage, the better the sound power output from the speaker.
