Built–In Interfaces
System Unit Interfaces
The system board's built–in interfaces have ports on the workstation rear panel.
Audio Interfaces
The J Class workstations have audio input and output capability through external input and output
connectors on the rear panel and through an internal speaker. The rear panel contains the Audio IN (Stereo
line–in) and Mic (Mic–in), and Audio OUT (Stereo line–out) and Headphones (Headphone–out)
connectors.
The audio connectors are standard stereo audio mini–jacks. Hewlett–Packard recommends using
gold–plated plugs available through audio retailers for best quality recording and playback through the
external connectors. The following is a summary of the workstation audio features:
