FEATURES

Your Optimus CD-3620/CD-3640 Por- table Compact Disc Player uses the latest digital audio technology to give you the clean, crisp sound of compact discs. You can connect the CD player to your home audio or car stereo sys- tem or connect a pair of stereo head- phones for portable, private listening.

The CD player’s features include:

Digital Anti-Shock System (DAS2) (CD-3640 only) — rapidly scans data from the CD and stores it in memory for uninterrupted play with no sound skip even when the CD player is ex- posed to shocks or vibration. This makes this CD player excellent for use in your vehicle.

Eight-Times Oversampling with Digital Filtering — improves the CD’s sound by multiplying the stan- dard 44.1 kHz sample rate by eight and using a digital filter to reduce or eliminate distortion.

1-Bit DAC — uses the latest in digital- to-analog conversion circuitry to accu- rately reproduce all sound levels with virtually no distortion.

Built-In Battery Charger — re- charges rechargeable batteries in- side the player when you use an AC or DC adapter.

Automatic Search Music System (ASMS) — lets you quickly locate and play any track on a CD.

Audible Search — helps you locate a particular section of a track by rapidly playing the CD in either direction.

Intro Scan — helps you locate a de- sired track by automatically playing the first 10 seconds of each track on the CD.

Programmable Play — lets you pro- gram and play up to 24 tracks in any sequence you choose.

Repeat Play — lets you automatically repeat a single track, an entire CD, or a programmed sequence.

Random Play — lets you play the tracks on a CD in random order.

Pause and Cue — lets you tempo- rarily stop play, or cue a track for play at a later time.

Extended Bass System — creates a fuller bass sound.

Auto Power On/Off — automatically turns on the CD player when you press PLAY and turns it off when you stop play or 2 minutes after the CD fin- ishes playing.
