2.14 Audio interfaces (CN5, CN1)

The PCM-5820 Series is equipped with a high quality audio
interface, which provides 16-bit CD quality recording and play-
back as well as OPL3 compatible FM music. It is supported by all
major operating systems and is completely compatible with Sound
Blaster Pro.

2.14.1 Audio connector (CN5)

The PCM-5820 Series provides all major signals on a 16-pin
flat-cable connector (CN5). These audio signals include Micro-
phone in (mono), Line in (stereo) and Speaker out (stereo). An
adapter cable is needed if traditional telephone jack connectors are
used for these audio signals.

2.14.2 CD audio input connector (CN1)

All CD-ROM drives can provide analog audio signal output when
used as a music CD player. The CN1 is a connector to input CD
audio signals into the audio controller. The audio cable of your
CD-ROM drive is suitable for connection to CN1.

2.14.3 Audio power source setting (J1)

The PCM-5820 Series is designed to work with a single +5 V
power supply as audio interfaces usually function under +5 V.
However, most audio controllers require an independant +12 V
power source since this avoids noise interference from other
digital circuits. By using J1, the PCM-5820 Series' audio interface
can also accept +12 V power sources for improved audio quality.
