PADS-USB-HUB
Pragmatic Audio Distribution System USB Audio HUB 3 Port
Default model color: Black
The PADS-USB-HUB 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.
This communication channel is accessed by the PC Audio Server as a virtual COM Port on the USB Port, and no special
drivers are needed for it under Windows 2000, XP and Vista. The server uses a very simple API to talk to the control
communication channel via the USB Port.
