5 USING THE AUDIO SYSTEM
The Enhanced Business Audio system supports recording and
playback of waveform (WAV) audio files, and playback of
Musical Instrument Digital Interface (MIDI) audio files.
The system is based on the Crystal Semiconductor CS4231
chipset which incorporates 16-bit digital audio circuitry, a
stereo analog mixer and an Ad Lib-compatible FM synthesizer.
The computer itself has an internal speaker, a master volume
control, and stereo input/output sockets for microphone,
headphones and line-level consumer audio.
Connecting audio devices and controlling output volume
There are two 3.5 mm stereo audio sockets on the left-hand
side of the system unit; an input socket and an output socket.
Audio inputs
The input socket, labelled with the icon, allows the
connection of audio sources to be used when monitoring or
recording sound. You can connect a microphone (such as the
one supplied), a personal stereo (tape or CD), or a line-in signal
from a high-fidelity tape deck or CD player.
The mono microphone provided with the computer can be
worn clipped to your clothing, or mounted on the keyboard.
The microphone is switched on by sliding the cover back to
expose the grille.
