The PADS-USB-HUB is an Audio Distribution System is a standalone device that attaches to the USB port of any PC based audio server. It provides up to three channels of stereo audio along with a control communication channel for transport over CAT-5 cable to PADS audio endpoints. The PADS-USB-HUB is independently powered and provides power to the audio endpoints. The PC based audio server sees the three audio channels as three separate USB audio-DACs native to the server. No special drivers are needed for these DACs under Windows 2000, XP and Vista. Any PC audio application e.g. windows media player on the can open these DACs as native audio devices and send music to them. The communication channel is used to communicate with the local microprocessor in the audio endpoints, for receiving user commands and status information from buttons on the audio endpoints and for sending music captioning information to the audio endpoints.
