Chapter 2 Installation 232.14 Audio interfaces (CN5, CN1)The PCM-5820 Series is equipped with a high quality audiointerface, which provides 16-bit CD quality recording and play-back as well as OPL3 compatible FM music. It is supported by allmajor operating systems and is completely compatible with SoundBlaster Pro.2.14.1 Audio connector (CN5)The PCM-5820 Series provides all major signals on a 16-pinflat-cable connector (CN5). These audio signals include Micro-phone in (mono), Line in (stereo) and Speaker out (stereo). Anadapter cable is needed if traditional telephone jack connectors areused for these audio signals.2.14.2 CD audio input connector (CN1)All CD-ROM drives can provide analog audio signal output whenused as a music CD player. The CN1 is a connector to input CDaudio signals into the audio controller. The audio cable of yourCD-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 Vpower supply as audio interfaces usually function under +5 V.However, most audio controllers require an independant +12 Vpower source since this avoids noise interference from otherdigital circuits. By using J1, the PCM-5820 Series' audio interfacecan also accept +12 V power sources for improved audio quality.Table 2-3: Audio power source setting* +5 V +12 VJ1* default setting1 2 3 1 2 3
