iMac (Flat Panel): About the Sound System

This document discusses the iMac (Flat Panel) computer's sound system.

Sound System

The sound system provides sound input and output through the built-in microphone and speaker. External input and output devices can also be connected by way of the headphone sound output port, the Apple Speaker sound output port, and the USB ports.

Note: Some configurations come with Apple Pro Speakers.

To maintain the highest fidelity when playing digital audio program material from CDs or DVD-Video discs, the audio data is kept in digital form until just before being sent to a sound output port. A switch-mode power amplifier provides the power for the external speaker.

The sound system works with sample sizes up to 24 bits and sample rates of up to 48 kHz.
