Audio Connectors and Headers

The board contains audio connectors and headers on both the back panel and the
component side of the board. The component-side audio headers include front panel
audio (a 2 x 5-pin header that provides mic in and line out signals for front panel audio
connectors). The available configurable back panel audio connectors are shown in
Figure 6.
NOTE
The analog circuit of the back panel audio line out connector is designed to power
headphones or amplified speakers only. Poor audio quality occurs if passive (non-
amplified) speakers are connected to this output.
