The Philips CD200 - ahead from the start
The arrival of Compact Disc
The time has come. Compact Disc Digital Audio is here. The new "miracle" system for enduringly better sound and computer-age operating convenience.
Pure, perfect sound
Compact Disc Digital Audio is a totally new sound source; fully digital, and astonishingly accurate. From the master recording right through to the stereo signals that feeds the audio amplifier - nothing is added, nothing is taken away.
From the lowest frequencies to the highest levels, the sound that is heard is an exact copy of the sound that was recorded; no detectable noise, no measurable wow and flutter.
Dynamic range is exceptional, frequency response is mirrorflat, and overall channel separation and phase linearity are extremely good.
In a word, Compact Disc sound is purer - and you can certainly hear the difference.
Sound in shining armour
The digital recording is sealed inside the shining silver disc - safe from scratches, fingerprints and dirt. The pick-up is a laser beam. It could not wear out a disc if it ran for a hundred years. Special modulation (EFM) and error correction (CIRC) systems optimise signal handling and further suppress the effects of marks and scratches.
Thus, pure Compact Disc sound is everlasting sound. In normal use, CD recordings far outlast any conventional record.
Automatic control and direct access
Compact Disc introduces a totally new concept of ease, convenience and programmability. The digital codes on the record, detected in the player under fingertip control, and introduce unprecedented programming potential. Philips use this potential to great effect in the Philips CD200.
Plentiful software
Compact Disc already has big support from the recording studios. Many familiar labels appear on these shining silver discs, so that a wide choice of music from the world's leading artistes is available. And choice will expand fast as more and more CD players come into use.
The best sound ever
The CD200 is more than just a Compact Disc player; it offers the highest sound quality, the greatest operating ease and facility, and the best reliability - because Philips have the priceless advantage of the longest experience in Compact Disc technology.
Rack top or free-standing
The slimline CD200 is 420mm wide - the standard width of most of today's system components. So it makes a perfectly fitting crown for a HiFi rack.
Alternatively, it is an exciting focus of attention as a free-standing HiFi component.
Connects to any sound installation
The CD200 connects directly to any sound installation with a line input (CD/TV, AUX, TAPE or TUNER). It will bring the very best out of any installation, but the better the sysyem, the bigger the advantage gained.

人老是自然规律。等那些老的烧友仙去，你也会变老了的。当你老了的时候你会知道，在对声音的整体领会中，並不是能听到更高频率，就等于会听音乐。总不会认为儿童比你更会理解音乐吧？而且这样不着边际的比较，什么也说明不了吗，这就像说调查过某二个收入相差几十倍的人，证明收入
